At Philly International we reached 71 in the afternoon before some light showers pushed through in the late afternoon; this was due to a cold front pushing across the region and the wind shifts overnight. Lows will be in the upper 40s, but then on Sunday highs will be in the lower 60s with a gusty northwesterly wind between 10-20mph.
Same thing goes for Monday with highs in the lower 60s, but then a potent area of low pressure will provide rain for much of the rest of the week; the front itself moves slowly and with a southerly flow this will just push in plenty of moisture from the Gulf of Mexico. More on that come Sunday.
