|Intense downpours and thunderous cracks of lightning will limit today's outdoor activities from the southern Plains to the Southeast. In the wake of the wet weather, temperatures will take a sharp 10-to-20 degree drop across the Northern Tier leaving things feeling more like late-winter tonight into Monday.|
WeatherBug Meteorologist Mace Michaels has the latest in his exclusive WeatherBug National Outlook.
Several energetic disturbances from late this week will continue to make their way toward the Great Lakes, where they will join forces to form a powerful storm system late Sunday. However, before these disturbances reach the Lakes, they will work in tandem to spread wet, stormy weather across the eastern half of the U.S.
Showers and thunderstorms from Saturday will continue to wring out deep Gulf moisture from the eastern Great Plains to the Eastern Seaboard Sunday. Heavier rainfall accumulations in excess of 2 inches will be possible across the Virginia-North Carolina Piedmont.
Atmospheric conditions favorable for severe weather will help to spark dangerous thunderstorms this afternoon and evening from the southern Ohio Valley down to the western and central Gulf Coast and the western Carolinas. These stronger storms will be capable of damaging winds, large hail and even a tornado or two.
Further west, lingering moisture over the Mountain West will aid in bringing another round of light rain and snow showers to the Rockies throughout the day, while mountain thundershowers bring a few raindrops to the Sierra Nevada.
Overnight, temperatures will drop just enough across northern portions of North Dakota and Minnesota to transition light rain to flurries of snow.
The rest of the U.S. will look to close out the week with pleasant conditions and plenty of spring sunshine.
Chilly highs in the 20s, 30s and 40s will keep to the higher elevations of the Rockies. Meanwhile, Saturday`s highs in the 60s and 70s across the Northern Tier will drop down into the upper 40s and 50s from the northern and central Plains to the Great Lakes and Northeast. Warmer 60s, 70s and 80s will wrap up the week for the rest of the U.S., while highs reach into the toasty lower 90s across South Florida, the Desert Southwest, the Rio Grande Valley, and the southern Sacramento Valley.
