Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 423 AM EDT Mon Mar 30 2020 Valid 12Z Mon Mar 30 2020 - 12Z Wed Apr 01 2020 ...Pacific storm to make for a wet and wintry start to the week in the Northwest... ...Low pressure system lingering over the Northeast expected to bring additional snowfall for northern New England... ...Developing area of low pressure expected to spread heavy rain and thunderstorms quickly across the Deep South to the Southeast... Quite an active weather pattern is expected for the next few days as three major systems are expected to affect many parts of the country. The low pressure system responsible for widespread precipiation from the Great Lakes to the Northeast will weaken very slowly as it lingers over the Northeast for the next couple of days. This will keep a good chance of snow across northern New England through Wednesday morning where a few inches of additional accumulations can be expected. A cold front behind an intensifying storm off the New England coast will usher in cooler temperatures and drier conditions through much of the eastern U.S. today. This storm system will also push a back door cold front down from New England into the Mid-Atlantic on Tuesday as rain ahead of a low pressure system from the Deep South quickly moves into the Southeast and the Mid-Atlantic by Tuesday evening. This low pressure system is currently developing over the southern High Plains as an upper-level disturbance tracks across the Southwest. The storm will tap into Gulf moisture leading to a blossoming of showers and thunderstorms from the southern Plains Monday evening to the lower Mississippi Valley some time Monday night with a good chance for a quick round of heavy rain. By Tuesday, the storm will advance rapidly into the Southeast where heavy showers and a threat of severe thunderstorms are possible. By Wednesday morning, the storm center should continue to move rapidly off the Southeast U.S. coast, ending the rain over the Southeast. Farther north, some rain should linger over the Mid-Atlantic and the Ohio Valley near a surface trough. In the West, a northeast Pacific storm will roll into the Northwest on today, 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. Kong/Mullinax Graphics available at
