Wednesday Afternoon February 19 2025
Today, the winter storm is developing, and snow has reached parts of Central Maryland north of the computer model forecast, as I suggested. I was all excited to share the feature of the Baroclinic Leaf with you, and then the National Weather Service has added a NEW Winter Weather Advisory for parts of Central Maryland. This is for the additional light snow tomorrow with the second piece of energy. Nothing is new with my forecast, but this may get some additional attention.
From The National Weather Service
The new area includes metro Washington, DC, and parts of metro Baltimore.
In Central Maryland: Frederick, Carroll, Baltimore, Montgomery, Howard, Prince George, and Anne Arundel counties.
Southern Pennsylvania may get added later, as I see the same weather there.
Let me get this out of the way…
I only made a slight adjustment to my first call map and left it easy to identify… The wider range of snow showers on the north end.
The snow was seen very close to the line that included Washington, D.C., Annapolis… and just south of Baltimore.
Flurries may be reaching the ground in Northeastern Maryland’s Harford and Cecil Counties.
This may not seem like a big deal, but proves my efforts to suggest the snow would fall farther NORTH of where the models suggested.
Yes, I feel some vindication.
The storm has taken form with light snow reaching into Maryland just south of Baltimore.
Heavier snow is falling across Southeast Virginia and Eastern North Carolina. The main Low Pressure is in the Gulf west of Tampa.
Our next focus will be the energy in the jet stream that will cross the Midwest tonight and reach us tomorrow for that second impulse of light snow.
This is a feature seen on the Water Vapor satellite with a developing storm. A bright band on the edge of the main cloud line develops and shows the likely northward reach where steady snow can develop. I mentioned this in a prior report with the January 2000 winter storm.
This was seen at 1 PM along a line from Washington DC and Annapolis.
The other part of this storm that did not match up in time for a major event, will swing through tomorrow. This is the additional energy for light snow developing.
The main event will pass south, then the light snow will develop from The Midwest with additional energy tomorrow.
Again, this is the model that performed best with last weekend’s snow and sleet burst.
There will be a few hours with steady light snow or snow showers.
This may be enough to range from a coating to 1 inch of snow.
Yes, temps are cold enough for stickage on the pavement. If this arrives earlier, it may impact part of the commute.

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 also can 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
