Northeast - High pressure keeps much of New England on the dry and mild side today. An upper-low coming out of the Southeast will bring scattered showers and thunderstorms across much of the Mid-Atlantic today. Locally heavy rain is possible, especially in Virginia. Rain chances will try to increase across New England by later Sunday. Highs today will be in the 60s and 70s region wide. Similar temperatures will prevail on Sunday. Warmer air, 70s and 80s, builds into the region early to mid next week.

Midwest - Low pressure winding up in the Plains will keep things very unsettled and stormy into early next week. Several days of locally heavy rain may produce some flooding issues in the Dakotas and Minnesota. Strong to severe thunderstorms will erupt this afternoon from western Nebraska down through western Kansas into northwest Oklahoma. It will become quite windy down through the Plains, as well. Increasing severe storm and tornado threat on Sunday from Iowa and Nebraska into Kansas as the main upper trough ejects into the Plains. This has the potential to bring a significant tornado outbreak to a large area, especially Sunday and again on Monday. Very warm to hot weather will be in place both today and Sunday through the Plains with highs in the 80s and 90s. Cooler 60s and 70s will prevail in the Great Lakes.

South - A slow moving upper-low will bring a messy weather pattern for much the Southeast with plenty of showers and thunderstorms today. The main area of precipitation will be from KY to VA and down to central AL and GA. The severe threat is low, but locally heavy rainfall, 1 to 3 inches in spots, will be possible. Most areas will be dry west of the Mississippi River and through the Gulf Coast region. Highs will be in the 80s over much of the region. Some cooler 60s and 70s will be found in the Virginias. Highs will be in the 90s across much of Texas today (with a few 100s in West Texas). A severe thunderstorm and tornado outbreak is likely across Oklahoma and northern Texas late today into Sunday and Monday.

West - Showers and thunderstorms will be common today from Idaho and Utah up to Montana and down to northern Colorado Sunday. A few showers are likely from western Washington to northwest Oregon. Dry conditions expected across California and Nevada and through the Desert Southwest. Today's highs from near 60 to near 70 are found across lower elevations of the Pacific Northwest. The Great Basin will see highs mainly in the 70s. The Desert Southwest will see highs from the mid 80s to mid 90s.
