Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 202 AM EST Tue Feb 25 2020 Valid 12Z Tue Feb 25 2020 - 12Z Thu Feb 27 2020 ...February ending with a winter storm across the Great Lakes region... A multi-faceted storm system is currently evolving across the Midwest and Ohio Valley Tuesday morning, with snow expected to develop from northeast Missouri to southern Michigan as the surface low intensifies and a shortwave impulse arrives from the central Plains. The greatest snowfall totals are currently expected across southeast Michigan where six inches or greater of accumulation will be possible, and lighter amounts extending towards the southwest across central/northern Illinois and northeast Missouri. Moderate snow along with some light freezing rain is likely across northern New York and northern New England by Wednesday, and rain near the Interstate 95 corridor. In terms of rainfall potential, the majority of the heaviest rainfall will have exited the coast by Tuesday morning, with some lingering convection ahead of the front across north-central Florida with perhaps one to two inches possible through Tuesday night. Multiple rounds of light to moderate rain are expected across the northern Mid-Atlantic region as the surface low approaches, with over an inch expected across parts of Pennsylvania. A much cooler airmass will settle in behind the cold front across the East Coast region by Thursday, signaling a cold end to February. Elsewhere across the continental U.S., dry conditions are forecast from the Intermountain West to Texas, and also across the Upper Midwest where below normal temperatures are expected. Light snow is likely across portions of the central and northern High Plains, and also for portions of the northern Rockies and the Cascades. D.
