Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 238 AM EDT Sat Mar 21 2020 Valid 12Z Sat Mar 21 2020 - 12Z Mon Mar 23 2020 ...Much cooler temperatures expected from New England into the Mid-Atlantic on Saturday, while much above average temperatures continue from the Southeast into Florida... ..Wet weather to spread northeastward from the Southern Plains/Lower Mississippi Valley into the Ohio Valley/Mid-Atlantic... ...Wet weather also likely for Central to Southern California Sunday into Monday with accumulating snows in the Sierra... After the first full day of spring brought much above average temperatures across parts of the Northeast into the Mid-Atlantic, much cooler temperatures expected this weekend in the wake of a strong cold front that is pushing offshore of the Northeast this morning. Below average temperatures will also persist westward through the Ohio Valley, Great Lakes, Mississippi Valley and much of the Plains. Much above average temperatures will continue over the next two days from the eastern Gulf Coast, portions of the Southeast and into Florida. Along with the cooler temperatures across much of the Central to Eastern U.S., an increasingly wet pattern will develop this weekend as rains blossom over South Texas Saturday, spread into the Lower to Middle Mississippi Valley/Ohio Valley Sunday and the Appalachians/Mid Atlantic Sunday night into early Monday. Accumulating snows are possible on the northern edge of this developing precipitation region across portions of the Mid-West, Lower Great lakes and into the Northern Mid-Atlantic. A slow moving storm system off the California coast will be pushing eastward this weekend toward California. This will lead to increasing chances of wet weather late Sunday afternoon continuing into Sunday night over portions of Central to Southern California. Inland, accumulating snows are likely through the central Sierra. Oravec Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
