We reached 69 at Philly International Airport this afternoon after we dealt with "self destructive sunshine"; basically by the late morning we had reached our convective temperature(the approximate temperature the surface must warm to in order for clouds to develop) and so with enough mid-level moisture still available the clouds hung around, but we stayed dry since the atmosphere at the surface was very dry.
Overnight we'll have a few clouds around with lows in the upper 40s; this will lead to more clouds with another short wave pushing through so highs will be in the upper 60s. Ditto for Monday, but that's because of Friday's cold front retrograding closer to the coast.
On Tuesday highs will be in the lower 70s with a mostly sunny day, but then we cloud up overnight into Wednesday with an approaching warm front as lows will be around 60; Wednesday itself will be in the upper 60s with heavy rain possible as a cold front pushes through.
The funny thing is that come Thursday with high pressure and a westerly wind highs will be in the middle 70s!
That's it for now and be sure to check out the rest of the 7-day forecast(any time) at www.scottderekwx.com/forecast.html.
