Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 315 PM EDT Mon Mar 30 2020 Valid 00Z Tue Mar 31 2020 - 00Z Thu Apr 02 2020 ...Heavy rains and possible flash flooding Monday night/early Tuesday over the Lower Mississippi Valley. Heavy rains and potential severe weather across portions of the Southeast on Tuesday... ...Below average temperatures for the Pacific Northwest and much of the East over the next two days... ...Heavy snows likely through the Cascades and into the Northern Rockies. Light snows possible from northern New York State into northern New England... Active weather expected ahead of an area of low pressure forecast to move east from the Southern Plains into the Lower Mississippi Valley tonight and across the Southeast on Tuesday. Thunderstorms are expected to continue to enhance late this afternoon across the Southern Plains, moving into the Lower Mississippi Valley tonight. These storms will likely produce heavy rains and the potential for localized flash flooding. This heavy rain potential will continue on Tuesday across the Southeast, Southern Appalachians and Southern Mid Atlantic as the storm moves eastward. In addition, severe thunderstorms may affect portions of the Southeast from southern Alabama, Southern Georgia, far northern Florida into far southern South Carolina. Large portions of the country over the next two days will be in a cool spring weather pattern as upper level lows are anchored across the Pacific Northwest/southwest Canada and over the Northeast. These upper lows will keep temperatures below average from the Pacific Northwest, Northern Rockies and into the northern High Plains and across much of the east. The exception will be along the Gulf coast into Florida where much above average temperatures will continue Tuesday before cooler temperatures move in behind a cold front on Wednesday. Above average temperatures also likely from southern California, through the Southwest and across much of Plains over the next two days. In addition to the closed upper lows supporting below average temperatures, they will also support heavy snows from the Cascades of Washington & Oregon into the Northern Rockies. Snow totals over the next two days may be in the 1 to 2 foot range across those areas. Much lighter snows are also possible across northern New York State and northern New England where 1 to 3 inches are possible.
