Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 340 PM EDT Fri Mar 25 2016 Valid 00Z Sat Mar 26 2016 - 00Z Mon Mar 28 2016 ...Heavy rainfall and thunderstorms possible across the Deep South by Sunday... ...Light snow continues on Saturday across the Central Rockies and portions of the Northern Plains/Upper Midwest... ...More unsettled weather is in the forecast for the Pacific Northwest and Intermountain West... The southern portion of a cold front pushing off the Northeast coast this evening will stall over the Southeast and central Gulf of Mexico keeping showers and thunderstorms in the forecast through the weekend across these regions. By Saturday, the front is forecast to begin lifting northward as a warm front, which should bring heavier rain into the Central Gulf Coast region by Sunday morning. WPC has highlighted a slight risk for flash flooding along the boundary from the Central Gulf Coast to South Carolina on Sunday. A slow moving cold front across the Central Plains will push into the Mississippi Valley and the Ohio Valley this weekend. Light snow will continue over the Central Rockies as well as portions of the Northern Plains/Upper Midwest, with rain showers and thunderstorms developing by Saturday across portions of the Southern Plains to the Middle Mississippi Valley. Some scattered light rain or snow showers are also possible across parts of the Southern High Plains Saturday into Sunday as cold air filters in behind the boundary. By Sunday, interactions and instability between this front and the boundary along the Gulf Coast should allow for the development of isolated to scattered heavy rain and strong to severe thunderstorms across the Lower Mississippi Valley to the Tennessee Valley. The Northwest should get a brief break in the wet weather tonight before yet another system makes its way onshore by Saturday afternoon. Valley rain and mountain snow will spread across the Pacific Northwest on Saturday, and into the Intermountain West and Rockies by Sunday. Precipitation should be mostly light in nature with minimal accumulations limited to favorable upslope along the higher terrain.
