Thursday started off cloudy in the morning, but as high pressure pushed in from the north drier air pursued; after a mild low of 72 at Philadelphia International Airport the high reached 81 with sunshine and fair weather cumulus in the afternoon. There was a gusty northerly wind between 15-20mph throughout the day, but it still felt nice and refreshing!
Overnight will be clear and cool; lows will range from the upper 50s in the suburbs to the lower 60s in Center City. Friday will feature an easterly wind in the afternoon so despite plenty of sunshine highs will barely reach 80 degrees! A psuedo-warm front will approach by Saturday afternoon and provide some clouds(maybe an isolated shower north and west as highs reach the upper 80s, but Sunday and Labor will feel more like the Fourth of July! It will be hot and humid with highs 90 or better with an isolated chance of showers and thunderstorms in the afternoon(nothing severe, just your typical air mass thunderstorm) and overnight lows not dipping below 70!
Come Tuesday a more potent frontal boundary will approach from the west; it will be another day around 90(this could wind up being a heat wave as we'd have three days of temperatures 90 or greater) with showers and thunderstorms in the afternoon. Behind the front we'll still be in the middle and upper 80s, but it will be a bit drier than it has been.
