E PA/NJ/DE Autumn 2025 Obs/Discussion

Last night before midnight was our first below freezing temperature here in East Nantmeal since back on April 9th. That ends our freeze free growing season here in NW Chester County at 215 days. In the last 22 years the growing season has ranged from a few as 174 days in 2020 to 233 days in both 2005 and 2024. The earliest first freeze was October 13, 2012 and the latest November 23rd 2015. There has been some occasional snow flurries around the area today with temperatures remaining well below normal for mid-November with highs in the upper 30's. In fact, our high temperatures should stay below normal through the rest of the work week with highs remaining in the 40's in the hills and near 50 degrees in the valleys. We warm up well into the 50's by Sunday with rain chances increasing by then.

First flakes and solar storm upgraded to G4

But like clouds clouds clouds and overnight forecast is increasing clouds

Tomorrow night however the final solar blast expected to be the strongest a chance there of less clouds

If the below climate forecast model is to be believed....our area in the Northeast across the Northern Mid Atlantic would see some of the coldest temperatures relative to average over the next month through December 11th

Clouds cleared a little and believe it or not there’s some naked eye aurora on the horizon! Nothing like last October (yet) but it’s out there!

Some thin clouds here but stars are visible. Best I could do so far is some flickering on my camera.

Today should be almost 10 degrees warmer than yesterday...but still a few degrees below normal for mid-November with highs in the upper 40's to around 50 degrees. Temperatures look to stay near to below normal through Saturday before we briefly warm to above normal Sunday before falling back below normal to start the new work week. Our next rain chance looks to arrive Saturday night into Sunday.

Knew nothing about the Auora last night till my son mentioned it at 9:30. Amazing that it was that clear, and even more beautiful behind a lens.

 

BTW welcome back all the snowbirds to the forum. Happy tracking. Let's have some fun. Don't take it too seriously.
