Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 PM EST Sun Mar 03 2019 Valid 00Z Mon Mar 04 2019 - 00Z Wed Mar 06 2019 ...Heavy rainfall with a threat for flash flooding and severe weather to continue through tonight across parts of the Southeast... ...An east coast winter storm to bring hazardous winter travel conditions to the northern Mid-Atlantic and New England through Monday... ...Very cold airmass stays in place east of the Rockies Monday and Tuesday... A surface low moving off the Mid-Atlantic coast tonight will continue to allow for heavy rainfall and strong to severe thunderstorms along and ahead of the trailing cold front this evening, coming to an end overnight. Flash flooding and/or the risk for damaging winds and isolated tornadoes will be a threat, mainly across eastern parts of Georgia and the Carolinas. WPC continues the slight risk for excessive rains this evening, while SPC is also highlighting a slight to enhanced risk for severe thunderstorms. As the surface low exits the Mid-Atlantic and intensifies as it moves off the Northeast coast, moderate to heavy snows are likely from eastern Pennsylvania to Downeast Maine. Total accumulations of 6 to 10 inches is possible and hazardous travel conditions likely along the I-95 corridor from Philadelphia to Boston tonight and into Monday. Elsewhere, a bitterly cold airmass has already infiltrated the Central U.S. and will spread into the Eastern states as we begin the work week. Temperatures, especially across the Plains and into the Ohio Valley, could be as much as 20 to 40+ degrees below normal, with record min and max temperatures possible. Out West, a couple of week impulses aloft will continue to bring light to moderate snows to the higher terrain of the central Intermountain West and Colorado mountains on Monday, with another round of potentially heavy rainfall and mountain snows once again impacting California beginning on Tuesday.
