Highs and lows for Thursday
Highs and lows for Thursday

Despite morning thunderstorms and then before severe thunderstorms in the afternoon we reached 79 around 2pm at Philly International Airport after a low of 62. As of the 5pm climate report only 0.03" of rain fell, but overnight I'm sure that number will be closer to an inch thanks to the severe thunderstorms(with large hail).

A front is pushing offshore, but an upper level low sticks around for the next 48 hours

Overnight we'll have leftover showers and then a few clouds with lows in the middle 50s; Friday will be sun-filled, but then by the afternoon once we reach our convective temperature(the approximate temperature the surface must warm to in order for clouds to develop) we can see some isolated showers and non-severe thunderstorms pop up with highs in the lower 70s. Ditto for Saturday as the upper level low finally pushes away and high pressure moves in.

That high pressure sticks around for Sunday and Memorial Day and it will have a little "summer-like" feel to it as well; highs will range from the upper 70s to lower 80s with sunshine and some cumulus in the afternoon(so there won't be any issues with parades, memorial services, and barbeques). We'll cloud up on Tuesday with a backdoor front pushing through so ahead of that front we'll be in the middle and upper 80s while behind it we'll be back into the 70s.
