Monday was just like Sunday with sunshine and then some clouds in the afternoon(albeit the clouds were from an area of low pressure passing by to the south); highs at Philadelphia International Airport reached 83 this afternoon after a low of 63 shortly before 5pm. Granted our average high is 85 and our average low is 68 we are still running 2-5 degrees below average and will stay a few degrees below average this week(but who's really complaining? I bet you love the extra money in your pocket by not running your air conditioner 24/7!).
Overnight there will be a few clouds around so lows will be in the lower 60s(suburbs) to the middle 60s in Center City; Tuesday will feature sunshine and then some clouds as that frontal boundary is still passing by to the south. Highs will be in the lower 80s with an easterly(onshore) wind so the shore areas will be in the middle and upper 70s.
Wednesday will be sunny early, but then clouds push in by the afternoon as highs reach the middle 80s with a more southerly component to the wind(still an easterly wind along the shore so it will be in the 70s). Come overnight Wednesday into Thursday there will be a short wave that will be pushing eastward so there will be showers and thunderstorms with overnight lows in the upper 60s while highs will be in the lower 80s(it will feel very humid as well). We'll clear out by Friday afternoon with highs around 80, but we will have a north-northeasterly wind as high pressure works in from the north(it's almost like a backdoor cod front).
This means that Saturday will be sunny, but highs will just be in the upper 70s(that's almost ten degrees BELOW average!); Sunday will feature some clouds in the afternoon as an area of low pressure will retrograde closer to the coast despite highs around 80. Come Monday a frontal boundary from the west will approach the region so highs will be in the lower 80s, but rain shall hold off until next Tuesday.
