Some areas across the interior mid-Atlantic and central Appalachians may receive locally heavy downpours capable of producing isolated incidents of flash flooding.
A storm system moving across the northern tier of the United States will trigger severe storms capable of producing damaging winds and brief, torrential downpours in the western Plains, parts of the Dakotas and Upper Midwest.
To the south of these storms, extreme heat and humidity will bake the Central and Southern states and expand into the Midwest and eastern mid-Atlantic. Hot, dry weather in the Southwest will continue to enhance the risk of wildfire development and spread.
