Discussion
High pressure off the east coast in the classic “Bermuda high” position is pumping tropical moisture into the Mid-Atlantic region and the next few days will be quite oppressive with high heat and excessive humidity. In fact, heat indices - which are a measure of the discomfort caused by heat and humidity - will likely reach over 100 degrees during the next few days in much of the Mid-Atlantic region. This air mass is so humid with high precipitable water content that even though showers and thunderstorms will be spotty, any shower or storm that forms will be slow-moving and can produce heavy rainfall amounts in a short period of time.
