Weather Forecast Discussion

Warm, sun-sational weekend ahead of us

Rain and possibly a t-storm on Tuesday

TONIGHT: Clear and seasonable with diminishing winds. Low: 42

SATURDAY: Mostly sunny and very warm; a beautiful start to the weekend. High: 77

SATURDAY NIGHT: Clear to partly cloudy. Low: 46

It’s a rinse and repeat cycle with the weather across eastern Pennsylvania and western New Jersey. If you enjoyed the last couple days where we had cool nights, but pleasantly warm afternoons with plenty of sunshine well then you loved Friday. Temperatures hit the low 70s on Friday with just a few high, cirrus clouds overhead. The only complaint you may have had on Friday is the winds as they were whipping between 10 and 20 miles per hour throughout most of the day. The winds will diminish overnight as skies remain clear and temperatures fall into the seasonable cool low 40s.

High pressure will continue to strengthen and build overtop of the region on Saturday. Mostly sunny skies should take us through the day Saturday as a south breeze brings in warmer air. Afternoon high temperatures should rise well into the 70s. High pressure will move off the east coast for Sunday and with a clockwise flow of air around high pressure, this will continue to lead to a southerly wind flow keeping our temperatures warm. Afternoon highs Sunday should once again be well into the 70s with mainly sunny skies. There may be just a little more cloud cover moving in from our west Sunday.

We then track a fairly strong cold front moving in from our west late Monday into Tuesday. Clouds should be on the increase Monday and rain should eventually move in at night into Tuesday. The cold front expected to move through may tap into some tropical moisture as some computer models are showing a wave of low pressure developing around the Gulf Coast states and riding up along the boundary going into Tuesday. This could bring some Gulf of Mexico moisture up the east coast and that combined with the front could lead to heavy downpours. A t-storm is also not out of the question for Tuesday. The front looks to exit the region late Tuesday into Wednesday, but behind it, an upper-level trough builds in to keep things unsettled with the chance for a shower Wednesday and Thursday. This trough will also help to usher in the coolest air of the season so far across the region. It’s very well possible high temperatures on Thursday and Friday struggle to get out of the 50s. These numbers are actually a lot closer to seasonable levels than you probably think, but given how warm things have been overall the last several weeks, it may take a little time to get used to it.

Given the unseasonably warm start to fall, the fall foliage is running behind schedule this year by as much as one to two weeks. However, the two cool and frosty nights we had at the beginning of the week should start to accelerate the color change for many of us. Peak color is expected through parts of the Poconos this weekend, and that peak should gradually spread south through the rest of the area towards Halloween. Stay safe everyone and have a great weekend!
