Around the U.S.A.
High pressure will bring partly to mostly sunny skies and warm, moderately humid conditions from the Northeast to the Gulf Coast with high temperatures in the 80s and lower 90s. A trough of low pressure will produce scattered afternoon showers and thunderstorms in portions of Florida. A frontal system will cause clouds and showers in the upper Rockies and the upper Plains. Temperatures will be much cooler than normal there with highs only in the 40s and 50s.
