Sunshine will prevail farther south, where dry conditions and low humidity will result in a pleasant day across the Southeast.
In the Midwest, rain and storms will stretch from Michigan to Missouri, mainly later in the day. Texas will be mainly warm and humid, with periods of sunshine. Farther north, a mass of dry, chilly air will move into the Plains, providing plenty of sunshine.
Cool air will expand over the Rockies as well as a storm moves through the region, allowing heavy snow to begin falling over high elevations. Spotty, wintry precipitation will also spread over the mountains of Idaho, Montana and Wyoming.
The Pacific Northwest can expect increasingly cloudy and damp conditions as a storm approaches later in the day. The West will turn dry. Winds will increase the risk of wildfires in Southern California.
