Discussion
Our first extended stretch of very warm and humid weather will continue for the next few days with afternoon temperatures not far from 90 degrees right through mid-week. The main weather maker is a strong high pressure system over the western Atlantic Ocean which is pumping in the very warm and humid air mass from the southeastern states into the Mid-Atlantic region. The chance of showers and thunderstorms will exist each day through this very warm period given the high levels of low-level moisture. The highest chance for rain will come during the PM hours over the next few days and any shower or thunderstorm can produce some heavy rainfall. It turns cooler later in the week following the passage of a cold front.
