It seems that the "average" days just keep on coming; the average high at Philadelphia International Airport for late June is 85 while the average overnight low is 66. We reached a high of 86 shortly before 4pm after a low of 65 right before 5am this morning. That's as good as it gets! Granted there was more humidity than days past, it was still sunny through the day.

A warm front is progressing northward, but the showers and thunderstorms are staying to the west along the boundary

Overnight it will be partly cloudy and more humid with lows in the lower 70s; this means that Wednesday the only way for temperatures to go in up. We'll do that with highs in the upper 80s as sunshine will give way to clouds by the afternoon and we will have a few showers and thunderstorms by the evening commute as the cold front inches every so slowly to the east. Rain will continue through the overnight hours and into early Thursday morning as the cold front pushes eastward; as for rainfall amounts they will range from as little as 0.10" along Southern NJ to roughly 0.50" in Center City to possibly over 1" north and west.

The morning commute Thursday will be a little wet as rain begins to taper off, but the evening commute shall be fine as highs will be in the middle 80s. After lows in the upper 50s to around 60 overnight we'll have sunshine giving way to clouds in the afternoon on Friday as a short wave will be pushing through; 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.

The weekend right now looks to be 50/50 with sunshine on Saturday and highs in the middle 80s; come Sunday there will be a warm front trying to push northward which can spark off some showers and thunderstorms through the afternoon as highs try and make a run toward the upper 80s. Come Monday we will be hot and humid with highs around 90 as well as showers and thunderstorms in the afternoon as another frontal boundary pushes through.
