Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 308 PM EST Thu Feb 13 2020 Valid 00Z Fri Feb 14 2020 - 00Z Sun Feb 16 2020 ...Unsettled weather along the East Coast will move off into the Atlantic tonight into Friday morning... ...Heavy snow returns to higher elevations of the Pacific Northwest, Intermountain region, and into the northern Rockies... The widespread unsettled weather across the eastern U.S. and down along the Gulf Coast will come to an end by Friday morning as the associated low pressure/frontal complex moves quickly off the East Coast. Snow across the interior Northeast and thunderstorms over the Southeast will be replaced by cold and dry conditions on Friday. The high pressure system responsible for the cold weather will dominate much of the eastern U.S. through Saturday as it drifts east and settles along the Eastern Seaboard. Sub-zero temperatures are forecast for tonight and Friday morning over much of the upper Midwest and nearby northern Plains, spreading into northern New England by Saturday morning. Meanwhile, a series of low pressure systems and upper-level troughs are expected to track across the Pacific Northwest toward the northern Rockies for the next couple of days. This will keep a good chance of precipitation across the region through Saturday. The higher elevations will likely see heavy accumulations of wet snow especially later on Saturday. A piece of the energy from this system is forecast to eject eastward across the northern Plains on Saturday. This will trigger the formation of a low pressure wave along a warm front and produce wintry precipitation across the upper Midwest and into the Great Lakes on Saturday. Across Florida, showers and a few thunderstorms will slowly push southward through Saturday near and behind a cold front. Meanwhile, some moisture returning from the Gulf of Mexico could trigger showers along the western Gulf Coast as the high pressure system slides eastward into the Northeast later on Saturday.
