Another Update 11:42 pm: Some models don’t have us getting out of the 50s on Sunday.
Tonight’s models have trended towards last night’s NAM, which had the warm front not making it into Philadelphia.
Weak low pressure developing near the Delmarva coast will maintain a cooler east to northeasterly flow for Sunday. Low clouds, scattered sprinkles are possible in the morning. Some brightening skies possible, but not a certainty in the late afternoon.
While cloudy, it should be possible to get exercise outdoors.
At one point, thunderstorms seemed possible about 4-6 pm, but that looks unlikely now. Highs near 60 (instead of the mid 60s-70 that was previously forecast)..
