Staying Warm, But Humidity Remains On The Low Side Thursday

Wednesday's climate report
Wednesday's climate report
Scott Derek

Wednesday started off very humid with some leftover showers overnight as a cold front pushed through the region; the low at Philadelphia International Airport Wednesday morning was 73, but as drier air pushed in we had dewpoints fall back into the upper 50s and lower 60s across the region by the afternoon. Despite a northwesterly wind highs reached 85 this afternoon and that's because drier air warms up quicker and more evenly than moist air.

A frontal boundary remains to the south of the region; dry air with lower dewpoints stick around for Thursday

Overnight there will be a few clouds with lows ranging from the upper 50s well north and west to the lower 60s in the suburbs and upper 60s in Center City; Thursday will feature sunshine and a southeasterly wind which will propel highs toward the middle and upper 80s. High pressure will then provide a more southerly flow overnight into Friday which also means that the humidity will creep back up as well.

Highs on Friday will reach the upper 80s with an isolated shower or thunderstorm as a short wave passes through the region; Saturday will be in the lower 90s ahead of a cold front that will provide showers and thunderstorms in the afternoon. After some overnight showers and clouds we'll have drier air thanks to a cool shot of air from Canada; highs on Sunday will be in the upper 70s with morning clouds giving way to sunshine in the afternoon. We stay on either side of 80 degrees for the new work week as well.
