Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 410 PM EDT Sat Apr 10 2021 Valid 00Z Sun Apr 11 2021 - 00Z Tue Apr 13 2021 ...Stormy and unsettled weather pattern continues over much of the East for the rest of the weekend; severe weather possible from Georgia to Florida into Sunday... ...Accumulating wet snow expected across the far northern Plains on Monday following mixed rain and snow on Sunday... ...Elevated to critical fire weather risk remains in place for parts of the Southwest and southern High Plains... A low pressure system moving toward the Great Lakes will bring widespread unsettled weather across the eastern U.S. for the rest of the weekend as a cold upper-level trough pushes across the Northwest into the northern Plains. Severe weather and heavy downpours will be most likely across southern Georgia into northern Florida through tonight well ahead of a cold front moving into the Deep South. Meanwhile, a swath of rain will move across much of the Midwest into Sunday as the center of the low pressure system passes to the southeast. Rain and embedded strong thunderstorms are also in the forecast from the Great Lakes and Ohio Valley spreading into the Appalachians and the Mid-Atlantic tonight, then into the western and southern New England ahead of a warm front. Rain intensity should taper off over the Great Lakes later on Sunday as the system gradually weakens. However, a good chance and strong to severe thunderstorms is forecast for northern Florida on Sunday as the cold front approaches. Meanwhile, rain and embedded thunderstorms along the East Coast will gradually move out to sea later on Sunday as the cold front moves off the coast. In the Northwest, a cold upper-level trough will continue to bring below normal temperatures through the region as it helps the development of a new low pressure system across the northern Plains during the next couple of days. Scattered mountain snows across the Pacific Northwest are expected to move into the northern Rockies and the northern High Plains by this evening. Most snowfall accumulations should remain below 6 inches, with the exceptions being in the highest elevations of the Cascades and northern Rockies where higher amounts are possible. On Sunday, mixed rain and snow is expected to reach North Dakota as cold air wraps around the developing system. The system will attempt to merge with the weakening low pressure system over the Great Lakes to promote wet snow across North Dakota into northern Minnesota where up to 8 inches is possible near the Canadian border. Regarding other weather hazards around the country, fire weather conditions remain at elevated to critical levels in parts of the southern High Plains and southern Rockies tonight with slight improvement possible on Sunday. Elsewhere, the fire weather risk is elevated over central Florida. Kong Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
