Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 PM EDT Sun Apr 11 2021 Valid 00Z Mon Apr 12 2021 - 00Z Wed Apr 14 2021 ...Accumulating wet snow expected for the next couple of days across far Northern Plains as mountain snow gradually develops and expands across the northern and central Rockies... ...Strong to severe thunderstorms across central Florida will gradually subside later tonight... ...Unsettled weather continues over the Northeast as fire weather conditions give away to increasing chance of rain over the southern High Plains... A highly obstructed weather pattern across Canada will result in a low pressure system to remain nearly stationary over the Great Lakes for the next couple of days. Scattered areas of rain will possibly some embedded thunderstorms will linger from across the Great Lakes into the western portion of New England through Tuesday ahead of a weakening occluded front. Showers will be initially found over the Ohio Valley tonight. Some thunderstorms are also possible along the Mid-Atlantic coast before a cold front pushes the storms offshore by this evening, bringing in only slightly cooler and drier air into the East Coast on Monday. Meanwhile, the obstructed pattern over Canada will promote colder than normal conditions to persist across the Northwest and later into the northern and central Plains. Reinforcing shots of cold air rotating around the stationary low pressure system over the Great Lakes will provide to ingredients for wet snow to develop near the Canadian border over the northern Plains, which is forecast to persist into Tuesday. The snow is not particularly heavy at a given time but the persistent nature of the snow is forecast to result in 6 to 12 inches of wet snow to accumulate by Tuesday evening across the northern half of North Dakota into northwestern Minnesota. Farther west, the obstructed pattern will also help a cold upper low to form and dip across the Pacific Northwest toward the Southwest for the next couple of days. This will bring colder temperatures together with slow development and expansion of mountain snow across the northern and central Rockies. Regarding other weather hazards around the country, fire weather conditions remain at elevated levels in parts of the Southwest and the central High Plains today. Fire weather conditions improve in the central High Plain on Monday, but persist in portions of New Mexico and Arizona. Plus, abnormally chilly conditions have led to some Frost Advisories being issued for parts of the central Plains and along the coast of northern California and southwest Oregon. Lastly, there are a handful of High Wind Warnings in place for western South Dakota and Wyoming this morning. Wind Advisories have also been posted for the western Dakotas and eastern Montana through this evening as wind gusts could reach as high as 55 mph at times.
