December 22 Light Snow Or Mix Before A Mild Christmas Holiday Then Another Arctic Blast To End The Year
Monday, December 22, 2025
Today will be the coldest day of the week. We continue to be on the edge of a big warm-up in the middle of the nation, and winter hanging on in New England. The net result has us in the transition zone. That will put a light snow or mix on display Tuesday morning, while some accumulating snow will affect travel through the Poconos, New York, and New England.
Christmas looks mild, then another push of cold will include more icy mix to watch later this week.
On the bright side, today is the first FULL DAY of winter with daylight 2 seconds longer than yesterday!
HEADLINES
- Today the coolest day of the week

Looking Ahead: Friday to Sunday
- The next weather system will again track with our region on the edge.
- There has been a trend of colder air slipping into our region, which may allow for a period of freezing rain on Friday.
- Then a weekend warm-up ahead of the next push of cold air.
- This model shows freezing rain developing during the day. I’ve sped up the process with the expectation of that icy mix in the morning.

Jet Stream Friday to Next Monday
- While the middle of the nation will experience a large ridge and unseasonal warm up, I expect we will remain active on the edge of the influence in a battle zone.
- Following the rain event, Sunday will be one more push of arctic air worth watching BEFORE the end of the year.
- That cold shot will arrive just beyond our 7-day outlook shown below.

7 Day Forecast
Monday: Sunny and cool.
Tuesday: AM ‘mixed’ showers.
Christmas Eve: Mostly sunny.
Christmas Day: Mostly cloudy, a shower possible (40%).

RESTATING MY MESSAGE ABOUT DYSLEXIA
I am aware there are some spelling and grammar typos and occasional other glitches. I take responsibility for my mistakes and even the computer glitches I may miss. I have made a few public statements over the years, but if you are new here, you may have missed it: I have dyslexia and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had made it that far without knowing and to not let it be a crutch going forward. That was Mark Wysocki, and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I can also make mistakes in forecasting. No one is perfect at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. There has been no editor who can check my work while writing and to have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos when she is available. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm. #FITF
