Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 337 PM EDT Sun Mar 29 2020 Valid 00Z Mon Mar 30 2020 - 00Z Wed Apr 01 2020 ...Weekend storm system to generate showers and thunderstorms in the Northeast and Mid-Atlantic, snow in the northern Appalachians... ...Pacific storm to make for a wet and wintry start to the week in the Northwest... ...Developing area of low pressure to cause wet and stormy conditions from the Southern Plains to the Southeast... The storm system responsible for Saturday's episodes of severe weather and flash flooding in portions of the Mississippi and Ohio Valleys will track through the Great Lakes this evening. A cold front tracking across the South and Mid-Atlantic will usher in cooler temperatures and drier conditions on Monday. Meanwhile, showers and thunderstorms will track across the Mid-Atlantic and southern New England tonight while northern Maine witnesses measurable snowfall. The snow in northern New England is a result of a developing coastal low east of the Massachusetts Capes. Portions of northern Maine can expect over 6 inches of snow tonight before the snow tapers off Monday night. In wake of this storm system, a coastal front will push south from southern New England Tuesday to the Mid-Atlantic on Wednesday forcing cooler temperatures to stick around through mid-week. In the West, a northeast Pacific storm will roll into the Northwest on Monday bringing widespread showers and mountain snow to the Pacific Northwest, northern Great Basin, and Northern Rockies. The Cascades will measure snowfall in feet through mid-week while interior mountain ranges such as the Bitterroots, Sawtooths, and Tetons also pickup heavy snow. In addition, a cold frontal passage will lead to colder temperatures across the Northwest Monday night and lasting into the middle of the week. Farther south, an upper-level disturbance will track across the Southwest Monday morning. Ahead of this feature, an area of low pressure will form in the southern High Plains Monday afternoon. The developing storm system will tap into Gulf moisture leading to a blossoming shower and thunderstorm activity from the Southern Plains Monday evening to the Lower Mississippi Valley some time Monday night. There is a chance for flash flooding in parts of the South Central region Monday afternoon and into the overnight hours. By Tuesday, the storm will advance east and into the Southeast where heavy showers and a threat of severe thunderstorms are possible.
