Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 330 PM EDT Fri Apr 11 2025 Valid 00Z Sat Apr 12 2025 - 00Z Mon Apr 14 2025 ...Stormy weather from the Mid-Atlantic to the Northeast with late season accumulating snow in the higher elevations... ...Elevated to Critical fire weather conditions forecast for the Southern Plains Saturday and Sunday... ...Record warmth expected through the weekend for portions of the Intermountain West, Southwest, and Southern Plains... A slow-moving coastal low will create stormy weather conditions with widespread precipitation chances and gusty winds from the Mid-Atlantic to the Northeast this weekend. Heavy rain across the Mid-Atlantic today could result in isolated instances of flash flooding, especially in urban and poor drainage areas. As precipitation expands into the Northeast on Saturday, cooler temperatures will allow for a transition to wintry precipitation types. Higher elevations in the Northeast can expect precipitation to fall mainly as snow with accumulations of up to a few inches possible. Elsewhere in the Northeast, a mix of wintry precipitation and rain is expected. Precipitation will taper off on Sunday as the low moves towards the Canadian Maritimes, but gusty conditions may linger along the coast. In the West, a frontal system is expected to push south and east across the region this weekend, bringing precipitation chances from the Northwest across the Northern and Central Rockies to the Northern Plains and Upper Midwest. Precipitation will fall as rain at lower elevations and wintry mixed precipitation and snow at higher elevations. Wintry precipitation will also be possible Saturday night across the Northern and Central High Plains on the backside of the system. The central low associated with this system will strengthen over the Northern Rockies/Plains on Saturday then track toward the Upper Midwest on Sunday. Thunderstorms will be possible in the vicinity of the low, and isolated severe thunderstorms with damaging wind gusts will be possible Saturday afternoon. To the south of the western frontal system, dry downslope flow off of the Rocky Mountains is expected to create Elevated to Critical fire weather conditions across the Southern Plains Saturday and Sunday. Very low relative humidities combined with gusty winds will create favorable conditions for rapid fire spread. Temperature wise, an eastward moving upper ridge will result in well above normal temperatures across the Western and Central U.S. this weekend. The current forecast calls for record warm high temperatures for portions of the Intermountain West, Southwest, and Southern Plains with highs in the 80s and 90s. Some locations in the Southwest may see temperatures reach over 100 degrees. Below average temperatures are expected through the weekend for the Eastern U.S., and below average temperatures will also develop along the northern tier of the Western and Central U.S. with expected precipitation. River flooding is still ongoing in the Ohio and Mississippi Valleys from the multi-day heavy rainfall event last week, and Flood Warnings and Advisories remain in effect.
