Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 343 AM EST Mon Nov 02 2015 Valid 12Z Mon Nov 02 2015 - 12Z Wed Nov 04 2015 ...Heavy rain possible across portions of Alabama/Central Gulf Coast to southern Mid-Atlantic states... ...Snow possible over the parts of the Northern Rockies, the higher elevations of the Great Basin and the Sierras... An area of low pressure located over the Central Gulf Coast will lift toward the North Carolina coast by Tuesday. A quasi-stationary boundary will setup over central portions of Georgia and eastern half of the Carolinas. Gulf moisture will stream along this boundary, resulting in showers and thunderstorms over the Southeast and Mid-Atlantic states. As the system moves northeastward, the rain will be limited to the Southern Mid-Atlantic/Southeast Coast by Tuesday morning. The highest rainfall will concentrate over the Carolinas, where 2 to 4 inches (possibly higher) is forecast over the next three days. Flash flooding may occur with this system. Please refer to the Excessive Rainfall Outlook issued by WPC for additional information. Scattered to widespread showers are forecast for much of the Intermountain West, Great Basin and central Rockies regions over the next few days as an upper-level trough and associated low pressure system moves through. The northern portion of the front will track across the northern High Plains/Upper Midwest/Great Lakes region by Wednesday, reaching the Northeast by Wednesday. The central portion of the front will become quasi-stationary from parts of the Upper Great Lakes southwestward to the Central Rockies then southward over parts of the Great Basin into the Southwest. Areas of lower elevations will generally observe rain amounts less than 0.50 inch. Some of the higher elevations of the Northern Rockies and the Great Basin will transition to all snow by this afternoon -- the snow levels will fall as the upper-level trough moves inland. The highest points of the Sierras, Wasatch and central Rockies could see accumulations up to 1 foot, with liquid equivalents around 2 to 3 inches. The Tetons, Beartooths, Bridgers and Crazies of Wyoming and Montana could see snow amounts 10 to 20 inches, with up to 24 inches near Yellowstone.
