We hit 90 degrees just after 2pm at Philly International Airport after a low of 72 around 3am; we have hit 90 degrees or higher for JUST the third time this year, but the higher dewpoints(around 70 degrees) made it feel more like the middle 90s this afternoon. There were some scattered thunderstorms that passed west of the airport so only a trace of rain was recorded as of the 5pm advisory, but the overnight report will have whatever rain falls tonight up until 11:59pm.
Speaking of overnight lows will just be in the lower 70s with scattered showers and thunderstorms and then even some fog as a cold front pushes through; I really shouldn't really call it a cold front because behind the front is not cold air. It is a frontal boundary as it divides two different air masses so although rain will taper off by the morning commute we'll reach the upper 80s Thursday afternoon with sunshine, BUT be much drier thanks to a northerly wind.
Overnight Thursday it will be mostly clear with lows in the upper 50s and then Friday will start off sunny, but as a short wave pushes through the region by the afternoon we will have clouds bubble up once we
reach our convective temperature(the estimated temperature that the surface must warm to for clouds to develop); there may be a few light showers or sprinkles pushing through with highs in the lower 80s.
Right now the weekend is looking amazing with plenty of sunshine and highs on Saturday into the lower 80s with low humidity, but Sunday we'll feel a bit muggier with highs into the middle 80s; I feel that showers will hold off until Monday as a warm front progresses northward and then a better shot of rain comes Tuesday night into Wednesday morning with a cold front......but not before we reach the lower 90s.
