Weather Outlook for Friday
Fri 20 Nov 2009 07:15:15 EST
A complex low pressure system over the western Gulf Coast will produce heavy rainfall through Saturday morning before slowly edging eastward into the central Gulf Coast by Saturday evening. A strong south-southeasterly flow from the Gulf of Mexico is drawing a large amount of moisture into the western Gulf Coast. As the frontal boundary intercepts this plume of moisture, increased shower and thunderstorm activity is to be expected. Flooding is a definite concern given the large amounts of rain expected in a short time span. Active weather will continue across the West Coast as a series of upper level disturbances move over the Pacific Northwest. A cold front has moved onshore with widespread precipitation falling from northern California through the U.S./Canadian border. As the front moves eastward into the Intermountain West, much of the precipitation across the interior regions will change over to snow as the cooler air settles in. A upper low across the eastern Great Lakes and associated frontal system is moving into the New England states. A mix of rain showers and thunderstorms will move through the northeastern U.S. with the bulk of the activity winding down by Friday evening.
