Discussion

The atmospheric floodgates have opened up and hot and humid air has surged northward into the Mid-Atlantic region and it will stick around through the weekend. Temperatures, in fact, reached 90 degrees officially at Philly Intl Airport for the first time this year. A Bermuda high pressure type of system has set up along the eastern seaboard and it will continue to pump hot and humid air our way for the next few days. Temperatures will approach or slightly surpass 90 degrees each of the next three days along with plenty of sunshine and summer-like humidity values. A cold front should reach the east coast by later Sunday night and this will break the back of the season’s first heat wave by early next week.

Elsewhere, another round of severe weather is possible later today and this evening across the nation’s midsection as a cold front continues to press slowly to the east slamming into a very and humid air mass. This is the same frontal system that could bring heavy showers and strong thunderstorms to the Mid-Atlantic region by Sunday night as it nears the east coast. Also, as far as the sun is concerned, activity is once again quite low with few sunspot visible regions and no actively flaring sunspots.
