Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 321 PM EDT Mon Mar 23 2020 Valid 00Z Tue Mar 24 2020 - 00Z Thu Mar 26 2020 ...Early Spring Snowstorm for inland higher elevations of eastern New York State and New England... ...Severe weather possible across portions of the Central to Southern Plains into the Lower Mississippi Valley and Tennessee Valley... ...Below average temperatures for much of the West early this week, while May-like temperatures spread across the Plains, much of the South into Florida... Two well defined storms will progress from west to east across large portions of the nation over the next two days, supporting an active spring time precipitation pattern. The lead storm is strengthening off the Mid-Atlantic coast this afternoon and will be positioned near the southern New England coast Monday night into Tuesday. Moderate to heavy rain is likely across the Mid-Atlantic into New England. Farther north, heavy snow will take shape in the higher elevations of the Catskills, Adirondacks, Berkshires, Green and White Mountains this evening. Look for drier conditions to return on Tuesday as high pressure makes a brief stop over the Northeast before another round of precipitation arrive Tuesday night and into Wednesday. Behind this lead storm, another storm system is going to track across the Southwest this afternoon and into the Central to Southern Plains overnight. Modest precipitation amounts are expected with this storm system in the Southwest, Great Basin and Central Rockies. As this system emerges into the Plains late Monday into early Tuesday, precipitation coverage and intensities are forecast to increase as it taps into Gulf of Mexico moisture. Moderate to heavy rains expected to spread from portions of the Central Plains into the Mid Mississippi Valley, Ohio Valley, Tennessee Valley, and Appalachians Tuesday into Tuesday night. Thunderstorms with this system may produce severe weather from portions of the Central to Southern Plains, eastward into the Lower to Mid Mississippi Valley and Tennessee Valley. Localized areas of flash flooding are also possible in these areas as well. Periods of rain will then push into the Mid-Atlantic Tuesday night and into Wednesday as the storm tracks off the DelMarVa coast Wednesday afternoon. Some snow is possible in the higher elevations of the interior Northeast on Wednesday as well. A strong cold front will drop southeastward from the Pacific Northwest this afternoon across the Northern Rockies, Great Basin and as far south as southern California by early Wednesday. This front will cause temperatures to drop below normal through mid-week from the West Coast to the Central Rockies. Most of the West over the next few days can anticipate showery conditions in the lower elevations and snow at higher elevations. Meanwhile, temperatures across the South will look more like May with temperatures in the 70s and 80s. In fact, some locations in West and South Texas may soar as high as 90 degrees Wednesday afternoon. Mullinax Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
