Monday morning report

Due to some very cold nights, this light rainfall may continue. It only takes a few hours AND is just enough for a light coating. Light snow will drop a layer, but mixed with freezing rain will create a possible glaze as far north as central Maryland.

As you travel north, there will be more snow in the Poconos and greater Philadelphia to the New York metropolitan area. Again just a morning event.

Christmas looks cold and dry. Thursday’s snow potential is gone…so temperatures will be just slightly below average with rain and warm-ups through the weekend.

Looking ahead, there is disagreement in computer modeling about the end-of-year warm-up and the subsequent major cool-down from 2025.

Local morning temperatures

The ground was cold enough to withstand light accumulations of snow or glazing from freezing rain.

Doppler radar snapshot at 6 a.m

Brief snowfall will mix with sleet and freezing rain closer to Baltimore and Annapolis over the next two hours.

Morning surface weather

This is a weak system that will bring rapid snowfall through the Poconos and into the New York metropolitan area this morning.

Just a light layer along I-95.

Light snow to freezing rain in central Maryland will only last a few hours.

Live radar (NOT IN WINTER MODE)

Radar simulations

The models have issues with this rain line and differ in how it behaves in Maryland.

The agreement states that it will take a few hours and be completed by noon.

Friday to Monday

The pattern shift will result in showers on Saturday and more consistent rain on Sunday. This will be accompanied by an increase in warmer temperatures for a few days.

Jet stream forecast

Sunday to January 2nd: The warm-up phase will be short and it will get colder again at the beginning of January.

7 day forecast

Temperatures remain seasonally cold for a few days and fluctuate little.

The next storm will be part of the warmer layer of the jet stream and will bring us showers on Saturday. Then on Sunday there was heavier rain.

Temperatures can reach near 60°F for a few days, including New Year’s Day, then become noticeably colder in January.

REPEATING MY MESSAGE ON THE TOPIC OF LEGEND

I understand that there are some spelling and grammatical errors, as well as occasional other errors. I take responsibility for my mistakes and even the computer errors I may miss. I’ve made a few public statements over the years, but if you’re new here you may have missed it: I have dyslexia and found out about it in my sophomore year at Cornell University. However, that didn’t stop me from getting my degree in meteorology and being the first to receive the AMS CBM in the Baltimore/Washington area. One of my professors told me that I had made it this far without knowing it and that I shouldn’t let it be a crutch for the future. That was Mark Wysocki, and he was absolutely right! I miss my mistakes when proofreading myself. The automatic spell checker on my computer sometimes misses the mark and makes the problem worse. I can also make mistakes in forecasting. Nobody is perfect at predicting the future. All maps and information are correct. The “wordy” stuff can get sticky. There was no editor to review my work when writing and have it ready to ship in a newsworthy time frame. Barbara Werner is a member of the web team that helps me maintain this website. She has made it her mission to correct typos when available. That could be AFTER you read this. I accept that and perhaps prove that what you read is really mine… It’s part of my charm. #FITF
