Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 357 AM EDT Sun Mar 11 2018 Valid 12Z Sun Mar 11 2018 - 12Z Tue Mar 13 2018 ...Storm system developing over the southern U.S. this weekend... An evolving storm system over the south-central U.S. on Sunday will be the main weather story through early Tuesday. A surface low over the Deep South is forecast to become better organized as a shortwave disturbance approaches from the western High Plains. Showers and thunderstorms are expected to be widespread across most of the southeast U.S. as deep moisture from the Gulf of Mexico surges northward and interacts with a warm front. Some areas from Mississippi to southern Georgia could get an inch or more of rainfall through Monday, and there is also a slight risk for severe thunderstorms over the central Gulf Coast region. By Monday morning, a new surface low is forecast to develop near the southeast coast and become a nor'easter as it intensifies and moves toward the northeast. There is still some uncertainty on the future track of this storm and thus the direct impacts it will have from the Mid-Atlantic to New England. The best prospects for accumulating snow will be for the southern and central Appalachians and interior portions of New England. If the nor'easter tracks closer to the coast, then high winds and coastal flooding will be an issue. D. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
