E PA/NJ/DE Autumn 2025 Obs/Discussion

[ChescoWx]

Some unseasonably chilly air taking hold over the area this afternoon with dew points below freezing at 1pm. Actual air temperatures this afternoon are likely to remain in the 50's in the higher spots in the area. There is a frost advisory in effect for overnight tonight and I suspect that some of our valley locations in Chester and Berks Counties may actually see some near freezing temperatures which could effectively end the growing season in those spots. The higher ridge areas will stay well above freezing by morning. Attention will then turn to a potential nor’easter moving up the coast that could have some major impact to the area by the end of the weekend and start of next week. Oh and of course Go Phillies tonight!!

There looks to be agreement among the models that 1-2” of rain will fall Saturday night into Monday, possibly more in localized areas. The details are still being ironed out as there are some differences in when the most impactful rain and wind will be. That could come anytime between Sunday afternoon and Monday afternoon.

First frost this morning.  Low was 37.2F.

Bottomed out at 40 this morning here in NW Philly, the lowest since April 13 IMBY.  That will probably trigger some leaf coloring in the area (most of the tree leaves around here are still mostly green, with a few starting to yellow and others going direct to brown - probably from the lack of rain).

Currently clear and 44 with dp 35.

P.S. - I know Philly is in mourning this morning with a trifecta of Philly teams losing last night.

Gave her a 6/10 which is above average. But she could do better. Settle down...

Many spots below 400 feet ASL saw freezing temperatures this morning across Chester and Berks counties. Freezing temperatures were recorded at West Chester, Chester Springs, West Bradford Twp. Devault, Warwick Township and Nottingham. The coldest reading was the 28.9 degrees at Warwick. Here in East Nantmeal at 685 feet ASL we recorded a low of 37.5. This is a record low for this date for this location with records since 2004. Regarding the weekend coastal storm some models have backed off a bit on the westward extent of the heaviest rain across Chester and Berks counties. Rain chances start to increase by tomorrow evening, and showers could continue into Monday.

The trend is my friend for Sunday! Looks like models are converging on the strung out euro solution. Euro AI and Ukie most consistently showed this and never really got on board with a full phase
