Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 428 AM EDT Mon Mar 15 2021 Valid 12Z Mon Mar 15 2021 - 12Z Wed Mar 17 2021 ...Major winter storm winding down over the central Rockies to the north-central High Plains... ...Another low pressure system is forecast to bring more severe thunderstorms and heavy rain across the central Plains Tuesday and Wednesday, with additional snowfall across the central Rockies... ...Critical fire danger continues across parts of New Mexico and western Texas... A large and energetic low pressure system enveloping the mid-section of the country is showing signs of winding down after delivering one to two feet of snow to the central High Plains with higher amounts along the Front Range. Blizzard conditions in parts of the area have since subsided as the storm center slowly makes its way eastward into the central Plains. Nevertheless, a band of moderate snow with some mixed precipitation is moving across the Midwest and should reach the upper Midwest and lower Michigan by tonight. Some mixed precipitation should also move into the central Appalachians tonight well ahead of the weakening system. Across the Deep South, expect some thunderstorms to move into the region today and then lingers into Tuesday ahead of a weakening cold front. Rain and some embedded thunderstorms will likely move through the Mid-Atlantic states on Tuesday before clearing out Tuesday night as a new low pressure center forms and moves offshore. The current active weather pattern will tend to repeat itself as another upper trough is forecast to move through the Southwest. This will bring another around of mountain snow and lower elevation rain from west to east starting from California and the Pacific Northwest today followed by the southern Great Basin and the Four-Corner region on Tuesday. By Tuesday night into Wednesday morning, it appears that another significant low pressure system will begin to intensify over the southern Plains. This system should be less intense than its predecessor but a resurgent of Gulf moisture into the southern Plains will likely bring the next round of severe thunderstorms together with a band of heavy rain farther north across parts of the central Plains ahead of a developing warm front. Cold air on the back side of the storm will once again support moderate to possibly heavy snow spreading through the central to southern Rockies to the nearby High Plains while a band of mixed precipitation is possible farther east across the central High Plains Tuesday night and Wednesday morning. Some wintry precipitation is also expected across the northern Rockies Monday and Tuesday ahead of a cold front. Under this active weather pattern, dry and strong downslope winds south of the storm track will continue to promote elevated to critical fire danger across parts of the southern High Plains.
