Tuesday started off two degrees below average with a low of 66 at Philadelphia International Airport; there were some clouds along with sunshine throughout the day as the high temperature reached 87 in the early afternoon(which is two degree above average). There was an easterly(onshore) wind so the further away from the shore you were today the warmer it was; closer to the shore it was into the upper 70s thanks to the water temperature in the middle 70s. There were a few clouds pushing through in the early evening in wake of a few showers that fizzled out across Central Pennsylvania. Lows will range from the middle and upper 60s with a light easterly wind.
Wednesday will feature sunshine and then some clouds in the afternoon in response to an area of low pressure that will be progressing eastward; highs will range from the upper 70s at the shore to the middle 80s in Center City with a continued onshore wind(southeast to be exact). We'll stay dry through the afternoon, but overnight as lows will be in the upper 60s there will be showers and thunderstorms after lunchtime on Thursday with highs around 80(and a continued onshore wind).
Come Friday that are of low pressure weakens and high pressure regains control of our weather; we'll be mostly cloudy with a continued onshore wind with highs in the upper 70s. Both Saturday and Sunday shall feature sunshine and fair weather clouds in the afternoon with a northeast wind as highs will just be in the middle 70s(that's ten degrees BELOW average!).
We stay into the upper 70s for the new work week as well as our next chance of any rain will come mid-week with a frontal boundary. It definitely will feel like mid-to-late September by the end of this week and remember that you can check out the 7-day forecast(as well as obtain radar and satellite maps) any time at www.scottderekwx.com/forecast.html.
