Snow for the Mid-Atlantic and Northwest

Wed, 06 Mar 2013 07:40:28 EST
The surface low across the Ohio Valley continues to fill in as the primary low nears the Virginia/North Carolina border coast. Winter Storm Warnings and Winter Weather Advisories are in effect for much of the Ohio River Valley and Mid-Atlantic States, as well as portions of the southern Appalachians. Winter Storm Watches are also in effect for portions of southeastern New England. Snowfall accumulation rates will be most favorable west of the fall line (west of I-95), particularly farther west toward the higher elevations/Appalachians. Low pressure drifting into the Pacific Northwest will bring snow to the higher elevations of the Oregon Cascades and central/northern Sierras should receive the highest snow totals, with some locations likely receiving in excess of 12 inches. Details...

This system will shift into the Southern Plains on Tuesday. This may have an impact on travel conditions. Details...

Heavy Snows for the Northern Plains and Upper Midwest

Sun, 10 Feb 2013 07:54:36 EST
The stage has been set for another blizzard to impact the continental U.S.. Low pressure currently moving over southwest Nebraska will continue to move northeastward toward the Upper Peninsula of Michigan by Monday morning. The center of low pressure is actually expected to weaken just slightly as it moves toward the northeast but a threat of significant snow west and northwest of the center has led to the forecast of 4 to as much as 12 inches of snow from eastern South Dakota across southeast North Dakota into much of central and northern Minnesota/northwest Wisconsin and near the tip of Lake Superior. In addition to the snow, strong and gusty winds surrounding the deep surface cyclone will create dangerous white out conditions, and blizzard warnings have been issued for a large portion of the North Central U.S.. Details...

Heavy Snows and Strong Winds Diminish

Sat, 09 Feb 2013 07:43:09 EST
After dumping over two feet of snow across portions of the Northeast and bringing blizzard conditions to locations along the New England coast, the intense coastal storm should finally begin to weaken while lifting northeastward into the Canadian Maritimes. Reports of 20 inches to over nearly 3 feet have been reported by midnight across central Long Island and Connecticut. Elsewhere across Connecticut/Massachusetts/Rhode Island and Coastal Maine, Most total snowfall will likely be in the 1 to 2 foot range with locally higher amounts. Details...

Northeast Blizzard

Fri, 08 Feb 2013 07:13:28 EST
The merger of a southern stream shortwave/jet system with an amplifying northern stream trough is on target to produce a very intense cyclone off the southeast New England Coast late Friday and early Saturday. One relatively weak low pressure system over the Midwest will fill as another developing low along the Southeast Coast will become the primary circulation as it nears Cape Hatteras by morning and then moves offshore and continues to deepen well east of New Jersey Friday evening and then just east of Cape Cod by Saturday morning. Heavily populated areas from New York City to Boston could measure more than a foot of snow from the event, with locally higher amounts possible. The storm should slowly start to move away from the states Saturday afternoon, and conditions should gradually clear out from west to east across the Northeast. Details...

Snow for the Great Lakes into the Northeast

Thu, 07 Feb 2013 07:58:50 EST
A surface low lifting out of the Middle Mississippi Valley is expected to produce of stripe of moderate to heavy snow accumulations from southern Lake Michigan through Central Michigan today and across the eastern Great Lakes region tomorrow. With this northern system swinging into the Northeast/Northern Mid-Atlantic on Friday it will begin to phase with a southern stream shortwave lifting out of the southeast, driving a surface low center that will deepen rapidly as it tracks along the Mid-Atlantic to Northeast Coasts Friday and Saturday. This combination has the potential to deliver very heavy snows to portions of the Northeast, with the heaviest amounts centered from northern Connecticut and Rhode Island into central/eastern Massachusetts to southern New Hampshire and the southern Maine Coast where a high risk for a foot or more has been indicated. Expect the heavy snow threat to extend north along the Maine Coast on Saturday. Details...

Winter Storm for West Texas

Thu, 03 Jan 2013 07:22:56 EST
Snow is expected in western Texas. Temperatures across the central/southern Rockies into the plains are currently a good 10 to 20 degrees below average which will help set the stage for a moderate to locally heavy snow storm for west Texas today. Details...

Heavy Snow in West Virginia

Tue, 30 Oct 2012 08:15:19 EDT
Heavy snowfall is expected to continue today and tonight across portions of the central and southern Appalachians as sufficiently deep cold air persists around the southwestern flank of what is now post-tropical cyclone Sandy. Sandy will steadily weaken over the next few days and this will allow the heavy snowfall threat to diminish, especially by later Wednesday as the system begins lifting northward and away from the region. Total snowfall amounts for the event of 2 to 3 feet with locally higher amounts are expected through Wednesday especially over the higher terrain of central West Virginia. Snowfall totals of 1 to 2 feet are expected in the mountains of southwestern West Virginia down to the Kentucky border, with 12 to 18 inches of snow expected in the mountains along the North Carolina/Tennessee border and in the mountains of far western Maryland. Details...

Snow in the Central and Southern Appalachians

Mon, 29 Oct 2012 07:52:35 EDT
A major early-season snowstorm will impact portions of the central and southern Appalachians beginning today and continuing through wednesday as a very deep cyclone evolves over the Mid-Atlantic States. The slow movement of the inland post-tropical remnants of Sandy leads to a long duration event across the central Appalachians. Very intense moisture transport around the cyclone will combine with strong upslope flow in northwest facing terrain to produce heavy snow in the higher elevations of West Virginia with amounts tapering off north into Laurel Mountains of southwest Pennsylvania and heavy snow expected as far south as the Smoky Mountains of Tennessee/North Carolina, tapering off down towards the Georgia border. Details...

Snow in Northern Minnesota

Thu, 04 Oct 2012 08:46:48 EDT
Winter Storm Warnings and Winter Weather Advisories are in effect for eastern North Dakota and northern Minnesota where a changeover from rain to snow is expected by this afternoon and evening. Snowfall totals of 4 to 8 inches with isolated heavier amounts are expected over far northeastern North Dakota and across northern Minnesota. Some amounts of closer to a foot are possible near the Canadian border. Yesterday, a daily snowfall record was set in Billings, Montana with 2.3 inches of snow recorded. Details...

Snow in the Northern Rockies

Sat, 28 Apr 2012 08:00:29 EDT
A mid-upper level low across eastern Wyoming this morning will meander east and eventually north across the High Plains today and tonight, bringing periodic moderate to heavy snow showers across portions of the Northern Rockies above 4500-5000 feet, particularly across the Big Horn Mountains in north-central Wyoming where probabilities of an additional 4-8+ inches of snow will be highest through this evening. Details...

Light to Moderate snow for the Pacific Northwest

Fri, 30 Mar 2012 09:04:46 EDT
An approaching upper level jet streak will cause a trough to amplify off the Pacific Northwest Coast. Until then, expect continued strong, deep-layer moist west southwest flow and favorable orographic component to bring more heavy snowfall today/tonight across the Washington/Oregon Cascades and into the northern Rockies. New snowfall amounts will be highest today across the northern Washington Cascades, as well as in the Sawtooth/Teton ranges in central Idaho and western Wyoming. A period of light snow is expected tonight across the higher elevations of the southern tier of New York, and the northern border counties of Pennsylvania. Localized accumulations of 2 to 4 inches are anticipated by daybreak Saturday. Details...

Moderate snow over parts of California

Sun, 25 Mar 2012 08:14:24 EDT
Mountain snow will blanket sections of California as an upper cyclone feeds off a steady transport of Pacific moisture. Orographic lift along the favored terrain will lead to locally heavier pockets of precipitation. By Sunday night, the upper trough is expected to finally translate inland spreading scattered rain/snow showers to the interior mountain west. Highest snowfall accumulations are expected across the Shasta and southern Sierra Nevada with up to a foot possible through Tuesday morning. Details...

Moderate to heavy snow over parts of California

Sat, 24 Mar 2012 06:35:15 EDT
The approach of a jet streak in advance of an upper low should be in place across northern California Saturday and drift east Saturday night, bringing in an area of moderate to locally heavy snowfall amounts possible in the Shasta/Siskiyous/Trinity Alps. Snow should move further south on Sunday. The models still show enough cold air to warrant a risk of heavy snow into the southern Sierra Range. Details...

Snow over Colorado/far northern New Mexico Rockies

Mon, 06 Feb 2012 07:35:09 EST
Moist upslope southerly flow will bring a swath of light snowfall over portions of the Central Rockies, especially in central and southwest Colorado. The probability of significant snowfall (8 or more inches) will be less than 10 percent through Tuesday morning however, there will be a moderate risk for at least 4 inches across the San Juan Range in southwest Colorado. Details...

Snow scross the central Plains

Wed, 19 Jan 2011 06:30:15 EST
A short wave digging through the Inter-mountain West/Four Corners Region on Wednesday will proceed through the eastern two thirds of the country Thursday and Friday. The heavy snowfall potential today will be highlighted across the Colorado Rockies and across the central Plains into the middle Mississippi Valley. The heaviest snowfall of 4 to 8 inches appears likely from central Nebraska to northeastern Kansas and through north central Missouri, especially around the Kansas City metro area. Snow is also forecast over the Appalachians into New England. Details...

Snow and Ice for the Northeast

Tue, 18 Jan 2011 06:58:54 EST
The combination of an intensifying area of low pressure moving up the East Coast and a shallow but sub-freezing air mass entrenched across the Northeast and northern Mid-Atlantic states will result in widespread heavy snow and freezing rain on Tuesday. A deepening low moving up the coast will bring Atlantic moisture into the Northeast and New England for moderate to heavy snowfall and significant ice accumulations. A Pacific short wave will bring moderate to heavy snow from the Oregon Cascades to the Tetons. Details...

Snow across the Northern Plains and Midwest

Mon, 17 Jan 2011 07:48:03 EST
An upper disturbance will slide through the upper Mississippi Valley and weaken tremendously on Monday. This feature is already producing a wide and expansive shield of snow across Iowa and southern Minnesota early this morning. This light to moderate snow activity should lift off to the north and east into Wisconsin and Michigan and be completely detached from the deeper moisture content down south. A surface wave will track up the Southeast coast and draw north a surge of anomalous low level moisture. As this happens, a solid surface ridge established over the Northeast and wedging south into the Mid-Atlantic Region will remain locked in place. This shallow air mass will be difficult to erode initially, while strong mid-level warming and moisture content surges into the region very late Monday into Tuesday. The northern extent of the expanding precipitation should start off as some light snow and freezing rain. Details...

Snow across the northern Rockies, Cascades and Great Lakes

Sat, 15 Jan 2011 08:03:24 EST
A strong jet stream will focus orographic precipitation along the Canadian border, including the Cascades. Additional air off the Pacific will help raise snow levels as far east as northern Idaho. In the Northern Rockies, snow levels will continue to lift given westerly flow aloft. This will hold snow accumulations down a bit, but there should still be plenty of snow at higher elevations from Montana into northwest Wyoming. Across the Great Lakes and Midwest, the first in a series of mid level shortwaves and an associated surface low will scoot just north of the border. This will produce generally light to moderate snowfall amounts due to a pronounced lack of moisture. Cold advection in the wake of the low across the open waters of the Great Lakes will result in lake enhanced snowfall. This appears to be especially true to the lee of lakes Ontario and Erie. Details...

Snow across much of the northern tier of the U.S.

Fri, 14 Jan 2011 05:25:26 EST
A strong jet stream will focus on the Pacific Northwest, propelling Pacific moisture into the Northern Rockies. Expect areas of heavy orographically enhanced snow for the north end of the Washington Cascades into the Northern Rockies with focus on the Sawtooth, Tetons, and especially the Bitterroots. Accumulations in excess of 1 foot and locally up to 2 feet will be possible over the next three days. A deepening low moving from the Pacific Northwest will move over the Upper Midwest later today. As it does so, it should couple with low level east to southeast upslope flow to produce a streak of mainly light snow from eastern Montana into the Dakotas and eventually into the Great Lakes. A low to moderate risk of 4 inches is indicated north of the track of the low. Details...

Frost Advisories

Tue, 05 Oct 2010 05:25:22 EDT
Frost Advisory are in effect Tuesday morning for many areas from the Great Lakes region into the Mid-Mississippi Valley, Oklahoma, and east into the Tennessee and Ohio Valleys. Details...

Late season snows over the Colorado Rockies

Thu, 13 May 2010 05:25:47 EDT
An upper trough from the late season snow storm will partially remain over the Central Rockies on Thursday and Friday. Upper difluent flow and jet maxima will then remain somewhat stationary across Colorado, combined with a low level anticyclone over the Plains funneling low level moisture into the foothills/front range of Colorado will result in 4 to 8 inch snowfalls Thursday and Friday over the Colorado Rockies. Details...

Snow in the higher elevations of New England and the Northeast

Sun, 18 Oct 2009 07:30:40 EDT
As a low pressure system off the Mid-Atlantic coast moves northeast through sunday night, precipitattion will continue to wrap around west of the circulation center into western New England. While mostly rain is expected along the coast, accumulating snows are expected in the Berkshires of Massachusetts and nearby higher elevations in adjacent portions of New York, Vermont, New Hampshire, and Maine. Details...

Snow into the Northern Rockies

Thu, 14 May 2009 05:15:42 EDT
The passage of yet another low pressure center will bring the risk of 4 to locally 8 inch snowfall amounts to the higher elevations of the Pacific Northwest into the Northern Rockies. Snows in the northern and central Cascades should be tapering off Thursday morning. Snow should be spreading eastward during the day on Thursday from the Bitterroot Range into the Northern Rockies and the Absaroka Range as the low progresses east. Snow levels should start out fairly high, around 5000 feet, and then decrease somewhat. The best risk of heavier snow will be mainly confined to higher elevations. Details...

Disturbance in the upper atmosphere will bring widespread heavy snow to the Intermountain West

Thu, 22 Jan 2009 05:20:26 EST
An upper level disturbance off the coast of California will spread ample moisture into the Intermountain West. Widespread heavy snowfall is expected the next three days across the western terrain, especially in the Tetons/northern Wasatch and Colorado Rockies. Details...

Bitterly cold air continues to affect Northern Plains to New England

Thu, 15 Jan 2009 07:05:48 EST
A weak surface low exiting the Mid-Atlantic coast will bring an area of light snow from southeastern New York and New Jersey to southern New England. Heavy lake-effect snow is possible across parts of Michigan, northwest Pennsylvania, and southwest New York. Wind chill warnings and advisories remain for much of the Northern Plains and Midwest and into the Mid-Atlantic and New England. Winter storm and high wind warnings are up across interior parts of central Alaska. Details...

A fast moving clipper system bringing bitterly cold temperatures from Northern Plains to New England

Wed, 14 Jan 2009 06:42:05 EST
Record-breaking extreme cold is freezing the Northern Plains and Midwest and dropping temperatures close to 50 below in spots. The fast moving clipper system will reach eastward just north of the Ohio valley today and exit the New Jersey coast by early Thursday. In the wake of the clipper system, a surge of Arctic air will bring bitterly cold temperatures across the northern Plains, Midwest, and interior New England. Wind Chill Warnings are in effect for parts of the northern Plains and Midwest. Localized bands of heavy snow to the east and southeast of the Great Lakes is possible. Light snow is also possible from Montana through western Kansas. Details...

Snow and Cold across the Plains and Upper Mississippi Valley

Tue, 13 Jan 2009 06:47:33 EST

Developing winter storm over the Southern Plains will impact the Mid-Atlantic on Tuesday

Mon, 05 Jan 2009 05:27:35 EST
A strong mid/upper jet will send a stream of Pacific moisture across the Pacific Northwest and northern Great Basin/Northern Rockies. Most ranges east of the Cascades should remain cold enough for snow, with 1 foot amounts possible over the Washington Cascades and the terrain of northern Idaho. Over the Southern Plains, the developing wave will result in freezing rain developing over portions of north Texas and southeast Oklahoma into western and northern Arkansas. Models indicate that a quarter inch plus amounts of freezing rain are possible near the Dallas/Fort Worth and Little Rock areas through Tuesday morning. By Tuesday, a low will track west of the Appalachians from the Tennessee Valley to southern Ontario, resulting in a setup for widespread freezing rain and sleet from western Virginia and Maryland and eastern West Virginia through south central and into northeastern Pennsylvania. Details...

Moderate to heavy snow in parts of the Northeast, snow continues in mountains of the Pacific Northwest

Snows across parts of the Great Lakes and New England

Mon, 24 Nov 2008 05:37:05 EST
Low pressure moving from the Wisconsin/Illinois border to Lake Huron, combined with cold air in place will bring snow across Michigan and into Ohio. Heaviest snowfall will be in northern and central lower Michigan with lesser amounts into Ohio. Snow from this system will spread into parts of New York and Pennsylvania late Monday. Snow is also possible in the higher elevations of eastern West Virginia. As the low over Lake Huron deepens Tuesday and Wednesday, snow will increase over New York and New England. Snow is indicated in the northern White Mountains in northern New Hampshire and Maine where precipitation should start with a burst of moderate to heavy snow before changing over to rain. Westerly winds across the open waters of Lake Erie and Ontario will result in another round of lake effect snows Tuesday and Wednesday. Heaviest accumulations are expected to the lee of Lake Erie. Snows will be slower to develop to the lee of Lake Ontario. Details...

Lake effect snows tapering off

Sat, 22 Nov 2008 08:42:30 EST
Lake effect snows will be tapering off from west to east across the Great Lakes as conditions become less favorable. In addition to less favorable winds, the temperature at low levels will be increasing with time.

Wed, 31 Dec 1969 19:00:00 EST
An upper level trough exiting the Rockies will evolve into a Central Plains closed low with a deepening low level circulation. Models continue to suggest that precipitation will change to snow as dynamic cooling occurs and some low level cold air is drawn southwestward across parts of western and central Nebraska later Thursday and Thursday night. Localized 4 inch plus amounts are possible mainly over central Nebraska. Mid and upper level Pacific energy is forecast to approach the West Coast Thursday night as an elongated trough develops. Most of the mid level onshore flow and associated moisture will be reaching into northern and central California and southern Oregon. This system will bring a threat of snow amounts up to around 8 inches through the more favored higher elevations of the Sierra. Details...

Snow in the Colorado and Utah

Wed, 31 Dec 1969 19:00:00 EST
Ridging along the West Coast will help amplify a Trough downstream over the Great Basin on Friday, which will help develop a low pressure center over the western High Plains. Snow should be developing over the Rockies and then spread out over the Plains as the low deepens. The heavier snows are expected across the Colorado Rockies. The longer duration of snow is expected in the higher terrain where 4 to 8 inches are possible. Snow showers are expected behind the frontal boundary over parts of the Wasatch and Uintas Details...

Heavy snows in the Northwest and northern New England

Wed, 31 Dec 1969 19:00:00 EST
The Pacific storm system will bring moisture into the Pacific Northwest and Northern Rockies. The strong influx of Pacific moisture should support snowfall amounts of one foot on Friday, with the overall heaviest amounts primarily in the Washington Cascades, with secondary maxima in the Bitterroots and Sawtooth Ranges. In the Northeast, a developing low is forecast to remain off the New England coast today and tonight. An onshore flow will develop, supporting a band of snow today/tonight. By Saturday, the combination of the deepening low, onshore flow, a developing frontal system, and upper level disturbance will bring a threat of a significant snow event to parts of Maine and northern New England where a foot of snow is possible. Over the Great Lakes, a strong flow of Arctic air will result in areas of enhanced lake-effect snow showers. The greatest threat is on the south shore in southwest lower Michigan and adjacent Indiana. Details...

Lake effect snows downstream of the Great Lakes, another storm bringing snow to the West

Wed, 31 Dec 1969 19:00:00 EST
Over the eastern Great Lakes, significant lake effect snowfall is expected across Lake Erie and Lake Ontario. A moderate to high risk of 4 inches or more will be downwind of Lake Ontario in the Tug Hills region of western New York. A slight risk of 4 or more inches will be downwind of Lake Erie from the NY/PA border, along I-90 to Buffalo NY. In the West, moderate snowfall is expected across the Cascades and Siskiyous. Best threat for some 8 or more inch totals exist across the western slopes of the Oregon Cascades and southern slopes of the Trinity Alps. Snowfall accumulations of a foot or more are possible in the northern/central Sierra with 4 to 8 inches likely in the foothills between 3500-5000FT MSL by Sunday morning. There is a risk of of 4 to 8 inches of new snow in the western Oregon/northern and central Idaho ranges as well. Details...

Snows in the Central Plains and Northern Rockies

Wed, 31 Dec 1969 19:00:00 EST
A very dynamic low making its eastward from the western High Plains will be filling as it moves east across the Plains and finally opening up the system later tonight. With the system beginning to fill, snow should be weakening throughout the day over the Plains. In addition, the system will be moving into a warmer environment where temperatures will begin to limit the amount of ice crystals in the column. Model guidance indicates perhaps a couple more inches of snow, mainly in Kansas. Blizzard conditions will still be possible after the snow stops falling due to strong and gusty winds. Conditions should improve from west to east during the day. A Pacific trough dropping into the Northern Rockies will produce widespread but light snow over the Northern Rockies later tonight. The best chance for 4 inches of snow looks to be in parts of Idaho/Montana where amounts should be enhanced somewhat by additional low level lift due to orographics. Details...

Winter weather across the West, Rockies, and spreading into the Plains

Wed, 31 Dec 1969 19:00:00 EST
A series of upper level disturbances will move through the West Coast and eventually emerging into the Plains, helping spread of shower activity across much of Oregon and California the next 2 to 3 days. The larger snowfall accumulations are forecast in the Sierra/Cascades above 4500 FT MSL, and the Siskiyous above 4000 FT MSL. Orographic lift supports a foot or two above 5500 FT MSL with over 3 more feet of snow above 6500 FT MSL between today and Sunday morning in the Sierra. In the Rockies, snowfall accumulations will be highest above 6000 to 7000 FT MSL during the next several days in Idaho, northern Nevada, western Wyoming, and northwest Montana with convective elements dropping snow levels down below 5500 FT MSL. The disturbances will spread snow into the Plains and Midwest by early in the weekend. Details...

Snowfall in the California Sierra

Wed, 31 Dec 1969 19:00:00 EST
A closed upper low and trough will dig down the California coast on Sunday and move roughly parallel to the coast. Pacific moisture will move across southern California and into the central/southern Sierra. This should be ideal for moderate to heavy orographic snowfall on Sunday. Details...
