Storms are expected to persist Saturday in the Southeast as a trough of low pressure developing over the Gulf of Mexico spreads warm, humid air over Gulf coast states.
The system is expected to bring some severe storms that are likely to produce heavy rain, strong wind, large hail and possibly a tornado or two. Temperatures in parts of the South are expected to reach into the 100s.
In the Northeast, a low pressure system will spin over eastern Canada and push another cold front in from the Great Lakes, creating scattered showers and thunderstorms. Highs in the region are expected to reach into the mid-90s.
Parts of the northern Plains and upper Midwest could get scattered showers and afternoon thunderstorms, while the rest of the Plains is expected to remain sunny and warm. Temperatures in much of the nation's midsection are expected to be in the 90s.
Scattered storms are expected to dump rain on parts of the Southwest, while the rest of the West Coast is expected to remain hot and sunny.
Temperatures in the lower 48 states Friday ranged from a low of 34 degrees in Stanley, Idaho, to a high of 111 degrees in Blythe, Calif.
