Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 404 PM EDT Fri May 27 2022 Valid 00Z Sat May 28 2022 - 00Z Mon May 30 2022 ...There is a Slight Risk of excessive rainfall over parts of the Mid-Atlantic through Saturday morning... ...There is a Slight Risk of severe storms over parts of the Mid-Atlantic/Southeast and the Northern High Plains through Saturday morning... ...There is a Slight Risk of severe storms over parts of the Northern/Central Plains from Saturday to Sunday morning... ...There is a Critical Risk of fire weather over parts of the Southwest/Southern Rockies... On Friday night, a front extending from the Lower Great Lakes to the Southeast/Central Gulf Coast will slowly move off the Northeast/northern Mid-Atlantic Coast by Sunday morning. Showers and thunderstorms will develop along and ahead of the boundary through Saturday. In addition, the front and moisture pooling along the boundary will destabilize the atmosphere. Therefore, the SPC has issued a Slight Risk of severe thunderstorms over parts of the Mid-Atlantic/Southeast through Saturday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. In addition, showers and thunderstorms develop along the boundary from the Northeast to the Southeast. Therefore, the WPC has issued a Slight Risk of excessive rainfall over the Mid-Atlantic through Saturday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, and small streams the most vulnerable. On Saturday, the front continues to advance eastward. As a result, showers and thunderstorms will develop over the Northeast, the Mid-Atlantic Coast, and the Florida Peninsula, coming to an end overnight Saturday. Meanwhile, there is a complicated series of fronts moving across the Northern High Plains to the Northern Plains by Saturday morning. The boundaries will aid in producing light rain over parts of the Pacific Northwest and moving into the Northern Intermountain Region by Saturday morning. In addition, the front will destabilize the atmosphere over the Northern High Plains. Therefore, the SPC has issued a Slight Risk of severe thunderstorms over parts of the Northern High Plains through Saturday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a minimal threat of tornadoes. The severe thunderstorm threat continues on Saturday. Therefore, the SPC has issued a Slight Risk of severe thunderstorms over parts of the Northern/Central Plains from Saturday through Sunday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a minimal threat of tornadoes. In the meantime, a third front moves onshore over the Pacific Northwest and advances to the Northern Plains by Sunday. Light rain will return to the Pacific Northwest by late Saturday morning and expand into the Northern Intermountain Region by late Saturday afternoon. Overnight Saturday, the snow levels will lower over parts of the higher elevations. Therefore, the highest elevations of the Cascades and Northern Rockies will get light wet snow. As the front moves out of the Rockies onto the Plains, The threat of severe thunderstorms returns to the Northern/Central Plains on Sunday. Lastly, a Critical Risk of fire weather returns to the Southwest and the Southern Rockies on Saturday. The threat is due to strong gusty winds, dry fuels, and low humidity.
