High pressure will keep things quiet through Tuesday, with mild temperatures and increasing clouds overnight. We’ll also look out for a few areas of patchy fog toward the morning.
Tuesday should be mostly dry and comfortable, with highs in the upper 70s to low 80s. A few showers may pop up late in the day across far western areas, but widespread rain holds off until later.
Rain arrives Tuesday night as a cold front pushes through the region. Expect widespread showers and a few rumbles of thunder overnight, but no severe weather. Rain continues into Wednesday and wraps up by the evening as the front moves offshore.
Totals around 0.75 to 1 inch are likely, with a few spots seeing more. It’ll be noticeably cooler on Wednesday, with highs mainly in the upper 60s and lows dropping into the 40s, even the upper 30s in the Poconos.

The rest of the week looks dry and cool, thanks to high pressure building back in. Thursday night could be the chilliest so far this season. While temps warm a bit heading into the weekend, they’ll likely stay below average.
Looking ahead, there’s growing potential for a coastal low to develop and bring some unsettled weather by the weekend, but the details remain uncertain — something to keep an eye on as the forecast becomes clearer.
