Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 426 AM EDT Tue May 25 2021 Valid 12Z Tue May 25 2021 - 12Z Thu May 27 2021 ...Showers and thunderstorms across the Great Plains and Midwest will spread into the Northeast on Wednesday... ...More wet snow for the northern Rockies to North Dakota as strong to severe thunderstorms develop in the northern/central Plains... ...Heat intensifies along the East Coast on Wednesday... A large and rather intense low pressure system over south-central Canada will begin to move more quickly toward the northeast and intensify further. This will help pushing the trailing cold front more quickly across the Plains toward the eastern U.S. during the next couple of days. The associated scattered showers and thunderstorms will continue to be across the central to southern Plains into tonight. By Wednesday, a reinforcing cold front moving across the Great Lakes will push the showers and thunderstorms steadily eastward toward the northeastern U.S. as heat is forecast to intensify up and down the East Coast Wednesday afternoon. The Mid-Atlantic states could see readings challenging daily high temperature records, after another day of relatively cool and damp conditions today. Meanwhile, parts of the upper Midwest could see thunderstorms reaching severe levels this evening. The Northeast will see a higher chance for severe weather on Wednesday ahead of a strong cold front, with lower chances down across the Mid-Atlantic. In contrast to the heat in the East, cooler than normal conditions will continue across the Northwest. A frontal system currently entering the Pacific Northwest is forecast to bring another round of wet snow for the higher elevation of the northern Rockies on Wednesday. This system will then exit the Rockies later on Wednesday and trigger the next round of spring thunderstorms across the northern and central Plains. The Storm Prediction Center has issued an enhanced risk of severe weather across the north-central Plains Wednesday into early Thursday. By Thursday morning, the thunderstorms should be pushing east toward the Midwest while some wet snow could be falling in North Dakota on the northern periphery of a low pressure system developing in the central Plains. Meanwhile, precipitation associated with the next Pacific system is forecast to reach the Pacific Northwest early on Thursday. Kong Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
