The average high for Philadelphia International Airport is 85 while the average low is 67; we were right on par with the overnight low of 67 as it was an overcast sky with some light rain through the day. That cloud cover, however did limit how warm we got today(also a continued easterly wind doesn't help either). The high was just 74(which occurred before noontime mind you!) with 0.22" of rain measured through the day as well. The clouds and showers were from a piece of energy that was getting forced southward as high pressure was approaching from the northeast.
Overnight the showers have pushed enough south where we'll just have some partial cloudiness; lows will be in the lower 60s with even some fog possible in the valleys and the Pine Barrens. Sunday will start off with a few leftover clouds south, but for the most part it will be sun-filled with some fair weather cumulus popping up in the afternoon. Highs will be in the upper 70s with a continued easterly wind around 10mph.
Come Monday we'll get more into a southerly flow so highs will be in the upper 80s with a sun/cloud mix and ditto goes for Tuesday as well; come Wednesday not only does a warm front progress northward, but also Tropical Storm Cristobal will be passing by just a few hundred miles to our southeast. This means that there will be some extra clouds in the afternoon along the shore with some heavy surf as well. Highs will be in the upper 80s with showers and thunderstorms in the late afternoon leading into the evening ahead of a cold front; On Thursday the front pretty much stalls on top of the region and washes itself out so it will be mostly cloudy with highs in the middle 80s.
Rounding out the work week it will remain mostly cloudy with highs in the middle 80s and then another surge of warm air pushes in for Saturday with highs approaching 90(but we'll fine tune that in the week ahead since next weekend is Labor Day weekend and we want to end the Summer on a high and sunny note).
