Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 347 AM EDT Mon Mar 14 2016 Valid 12Z Mon Mar 14 2016 - 12Z Wed Mar 16 2016 ...Additional rain likely from Texas to Mississippi... ...Rain and mountain snow for the West Coast and Intermountain West... ...Strong storm system to affect the central U.S. by Tuesday... After days of heavy rainfall and flooding across Texas and the lower Mississippi Valley, the pattern will be changing as the deep moisture feed from the Gulf of Mexico weakens. River levels will remain quite high across this region as all of the rain water slowly drains away. Across the western U.S., a strong Pacific front progressing eastward will bring widespread showers and mountain snow through Tuesday across the West Coast and then the Intermountain West. The heaviest snow is likely for the Cascades and northern Rockies, where 1 to 2 feet of snow is possible. This same frontal boundary is expected to evolve into a large low pressure system over the Upper Midwest by Wednesday morning, which will likely have some snow across parts of the Dakotas and into Minnesota. Over the eastern U.S., periods of rain with a few thunderstorms are likely across the Ohio Valley, Great Lakes, and Mid-Atlantic region on Monday as moisture returns to the region from the south. Mild weather is expected to continue from the Deep South to the Southeast with highs in the 70s to low 80s through Tuesday, which is above seasonal averages. D.
