Friday started off with sunshine and then there were the clouds by mid-morning; there were also very heavy rains by noontime thanks to convergence(rising air) and then thunderstorms popped up which also induced flooding across the region(mostly east of I-95). Philadelphia International Airport reached a high of 83 shortly after noontime as the rains began; the low won't be reached until 11:59pm as we should get down to the upper 60s(68-70) overnight with an overcast sky and even some light rain and fog.
There will be an area of low pressure riding along the Jersey coastline early Saturday morning so showers and thunderstorms will continue for Saturday across the entire region; locally 1-2" may fall(heavier closer to the shore) so highs will just be in the upper 70s with a southeasterly wind around 10mph. Overnight Saturday it will remain in the upper 60s with light rain and also some fog as well. Highs on Sunday will be around 80 with a continued onshore wind as that stationary front pushes to the northeast; there will still be a rain chance, but it will primarily be isolated in nature and confined to the shore.
It all pushes away by Sunday evening and high pressure takes control for Monday; it will be sun-filled with lower humidity as highs will be in the middle 80s. Tuesday will start off sunny, but then clouds will push in ahead of a warm front. There may be some isolated showers and thunderstorms in the afternoon with highs in the upper 80s. Wednesday will feature showers and thunderstorms in the afternoon ahead of a cold front with highs in the middle 80s and while there may still be some showers overnight we'll clear out and dry out for Thursday with highs in the middle 80s and sunshine. Ditto goes for Friday as we head into next weekend with highs staying in the middle 80s.
Let's just focus on THIS weekend first with the rain before we look at NEXT weekend since the 7-day can change(the best weather model guidance is only accurate for up to five days); remember that you can check out the rest of the 7-day forecast(any time) at www.scottderekwx.com/forecast.html.
