Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 312 AM EDT Wed Apr 16 2014 Valid 12Z Wed Apr 16 2014 - 12Z Fri Apr 18 2014 ***Unseasonably cold across the central and eastern U.S.*** ***Round of snow for the Upper Midwest and northern Michigan*** ***More rain and snow showers returning to the West*** After several days of very warm temperatures by mid-April standards, a much colder air mass has settled into the central and eastern U.S. behind a strong cold front. After a frosty and record cold morning across many areas from the Deep South to the Northeast, a chilly day on Wednesday can be expected as the surface high from Canada settles in, under mostly sunny skies. Another cold night is expected on Wednesday night for the East Coast, but it may be a few degrees warmer than this morning's low temperatures. With the next storm system passing over the central and northern Rocky Mountains into the central U.S. on Wednesday, light to occasionally moderate snow is expected from central Minnesota to northern Michigan. As this system lifts northeastward into Canada, it is expected to weaken and produce less precipitation along the trailing cold front. Across the Pacific Northwest, conditions will be somewhat unsettled with moist onshore flow resulting in occasional rain and mountain snow showers. Temperatures along the West Coast should be close to seasonal average for the middle of the week. For the Florida peninsula, expect isolated showers with the easterly flow off the Atlantic. D.
