Thunderstorms will roll across the Plains on Sunday as weak areas of low pressure develop along a stationary front stretched from Colorado to the Carolinas. The greatest chance for rain and thunderstorms will be from central Oklahoma through western Illinois. This region will also see the greatest chance of severe thunderstorms, with damaging winds and frequent lightning expected in the region.
Less intense thunderstorms and rain should be expected from northern Texas through the Mid-Atlantic region.
The northeast will see a mixture of sun and clouds on Sunday, with the most dense cloud cover in the south, close to Virginia. Temperatures will warm up a bit, with highs expected to rise into the 50s at the coolest, and some locations will see temperatures in the 60s possibly reaching 70. South of the stationary front near the Carolinas, highs will climb into the 80s and 90s.
The Northern High Plains will also see wet weather on Sunday as low pressure rides the Canadian border. A few scattered showers and possibly thunderstorms are expected across Montana into the Dakotas. Thunderstorms are most likely in the mountains.
In the West, continued sunny skies and warm weather are on tap for Sunday as high pressure sits atop the Intermountain West.
