E PA/NJ/DE Winter 2025-26 Obs/Discussion

[ChescoWx]

Today will be our 15th of the last 16 days with below normal temperatures as our Top 10 coldest starts to December in our history continues. It’s sunny today but clouds will increase tomorrow with snow arriving after 10pm. Snow will continue overnight till around 8am on Sunday morning before ending. The current NWS forecast has between 2" to 4" of snow across the area. We could see some blowing and drifting snow by afternoon across the typical open field and roads. We look to stay below freezing until Wednesday and then finally see a nice warmup with temperatures several degrees above normal through next weekend before we chill down to close to normal levels for the Christmas Holiday.

New York poster are scared because no water in the reservoirs means no water for them regardless of how the polluted Hudson looks.  The bitter cold is locking up the streams everywhere with ice too- so the water intakes in the rivers will be the talk too. Just look around hear- the Jordan creek is already frozen over with the little water that is in it.  It might as well be empty. We really ne3d a 3-5 in rain event with 50 degrees for a 3-4 day duration event. Any one see that in their crystal ball?

January thaw?

Both Euro and GFS show the Christmas storm FWIW.

Snow arrives this evening after 7pm with maybe some rain at the onset across far southern and eastern areas of Chester into Delaware Counties. The snow should be ending by daybreak tomorrow morning. It will be windy and cold tomorrow with blowing and drifting snow and temperatures falling into the teens by afternoon. Of note we only need about 3 inches of snow to go to above normal snowfall for the season to date which is 4.4" after tomorrow. Our unseasonably cold weather looks like it will continue through mid-week. We finally see some warming on Thursday before we turn closer to normal temperatures to close out the week.
