Discussion              

With high pressure still in control, the high heat and humidity will continue for another couple of days in the Mid-Atlantic region. In fact, the heat both this afternoon and on Thursday can break records in some spots with expected highs well up in the 90’s (see below). Later tomorrow, the chance of showers and thunderstorms will increase as a frontal system approaches the area from the northwest. This front will tend to stall out in the general vicinity late in the week and that will result in unsettled weather conditions on Friday, Saturday and Sunday with the daily threat of showers and thunderstorms.

On the tropical scene, “Lee” will be closely monitored in coming days as it intensifies rapidly and potentially becomes a threat to the US east coast. Lee will probably reach hurricane status later today and will likely become a “major” hurricane by the weekend…maybe even intensify all the way to a “category 5” storm.

The record high temperature today at Philly Intl Airport (PHL) is 95 degrees set in 2018 and it is in jeopardy.
