E PA/NJ/DE Autumn 2025 Obs/Discussion

Is it too early to start looking at December? Unfortunately it seems like strong east coast ridging will kick off meteorological winter for us. Still far away, but most long range ensemble guidance supports temps reaching the 50s-70s. Thankfully short lived though as a really cold air mass will advect eastward by around December 5th. EPS Weeklies support a weak SER around this time, so maybe some overunning events next month?

I'm in a "townhouse" so basically a "row" ("attached" on both sides).  It got down to about 64 and once the heat was on, within a few days, and after the cold dry air after fropa, the humidity plunged to 22% (perfect for the expected static electricity zaps and nosebleeds).    Humidifiers were finally set up and i got the downstairs up to ~36% (with the upstairs ~40%, where the rain helped).  That 35% - 40% (max) range is good for me.  That central air heat can be a bear.

That's pretty impressive. I live in a twin and I'm exposed to the West/Northwest, so get blasted by the cold winds. Small house so doesn't take long to hear up. Normally nerd humidifier on in Jan and Feb.

We picked up between 0.24" to 0.35" of rain overnight. The weather finally turns sunnier for the next 3 days with temperatures not too far from normal for late November. Rain chances increase by Tuesday night into Wednesday with temperatures by Wednesday PM not too far from 60 degrees! We turn sharply colder by Thanksgiving and the rest of the holiday weekend.
