Winter Storm Update: My Second Call For Snowfall Saturday And Ravens Game Weather

Thursday Evening Update January 9 2025

The winter storm that brought snow and ice to Dallas TX today is continue its path to the east. The Low Pressure near Houston is a southern storm that in many years could be a prime location to turn into a major nor’easter up the coast. This time the cold air to the north is too strong and the other energy that would be needed to create that for is not going to sync up. This will track off the Mid Atlantic coast and favor the southern part of our region with more snow. The rest of our area will get light snow.

If you were following with my repots earlier this week, that means once again the European ECMWF Model is correct, and the American GFS over played its hand.

Friday Night Event Ends Saturday Morning

Now that we are closer to the event, I want to show a high resolution model that I believe is doing a good job with the timing.  As for the snow totals, I made some slight adjustments to my forecast map. I will show that in contrast with the latest model forecast maps for you to compare.

Winter Storm Severity Index

A major snow and ice impact from Dallas to Atlanta over the next two days. A minor impact is expected for our southern areas in Southern Maryland and Virginia.

Winter Storm Alerts

A Winter Storm Warning now extends to the Carolinas and The Virginia Coast. This will include both snow and an ice storm.

A Winter Weather Advisory for lighter snow on the west and north side.

The Winter Storm Watch includes Southeast Virgina.

I do believe a Winter Weather Advisory may be issued for Southern Maryland on Friday for the overnight event.

Storm Forecast: Friday Morning to Saturday Night

ECMWF Model

Tracking the Gulf Coast Low to the East Coast Departure

This model has been the most consistent and I believe worth relying on again.

Saturday Morning Snapshot

This model has been very consistent. It has pushed a burst of snow into Southern Maryland at the end Saturday morning.

Radar Simulation

NAM 3 Km Model 10 PM Fri to Noon Sat

Midnight Snapshot

This may be the arrival of the snow into metro Baltimore, down to Annapolis, and north to York PA.

Early Morning: 4 AM

This may be the peak snowfall in the urban areas.

A dry slot will show up in Northern Virginia, while snow will continue in the mountains.

Daybreak at 7 AM

The snow may be coming to an end by first light in the urban areas.

An extra hour or two of snow may continue on Delmarva.

Temperatures

It will remain cold enough for the snow to stick. Also, the colder 20s in central Maryland and inland will make for a light and fluffy snow.

We will look at the Ravens Game Weather below the snow maps.

10 AM

Mountain Snow

There has been epic snowfall across the larger ski resorts in the last week. These will continue to get more.

My Second Call For Snowfall

Compare to the Model Snow Forecast Maps Below

Much of the region can expect roughly 1 inch of snow.  I’ve lowered my expectations to expand this to over more of our region.

Southern Maryland South of the Bay Bridge may get 1 to 2 inches. Higher amounts across far southern Delmarva.

There will be additional snow in the western mountains, where snow will continue all day.

Pennsylvania looks like they will be part of the dry slot… so I’ve expanded the Up to 1 inch range through Harrisburg and the lower Poconos.

Computer Model Snow Forecasts

European ECWMF

This is the most reasonable to me at this time.

NAM 3Km Model

While I agree with the timeline I showed above, I do not agree with these higher totals.

GFS Model

The highest amount of snow.

Canadian GEM

The lowest amount of snow.

National Weather Service

RAVENS GAME WEATHER

Afternoon Temperatures

Tailgating will be barely above freezing.

8 PM

Temperatures

Dropping back into the 20s.

Wind Forecast

Gusts to 30 mph will definitely make it feel colder.

Wind Chill

It will start to feel like the teens.

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 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
