Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 304 AM EDT Sat Apr 27 2019 Valid 12Z Sat Apr 27 2019 - 12Z Mon Apr 29 2019 ...Improving weather for the Eastern U.S. and late season winter storm expected for the Upper Midwest... The strong storm system that affected the East Coast on Friday has now exited the region with the exception of eastern New England. Periods of rain will continue through Friday morning as moisture surges inland from the Atlantic ahead of the cold front, with improving conditions expected by Friday night as the disturbance moves northeast across eastern Canada. Dry conditions are expected farther south across the Mid-Atlantic and Southeast on Saturday as high pressure builds into the region. A shortwave impulse tracking across the central plains will sustain a surface low across the Midwest states on Saturday. The majority of the precipitation with this event is expected north of the surface low track from South Dakota to southern Michigan. Late season accumulating snow is expected on the northern edge of the precipitation with several inches of snow likely from southern Minnesota to near the greater Chicago area, with winter storm warnings in effect for parts of these areas. In the warm sector of this low, scattered showers and storms are likely across parts of Oklahoma, Arkansas, and northern Texas, with some severe storms possible. Towards Saturday night and Sunday, a second storm system organizes over the Rockies and western High Plains in response to a closed upper level low. This will likely result in heavy mountain snow across western Montana and extending eastward across parts of North Dakota, and gusty winds for the Intermountain West behind the cold front. Another round of heavy rain is likely across the central plains ahead of the surface low. D. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
