Saturday January 20 2024
Not only did we get our first accumulating snow in two years this past week, but we had two events! This storm initially looked like the prior one on Tuesday, then pulled back, only to be yet another overachiever. Or, as some have suggested, was it just under forecast? You make the call. I did my best to start conservatively again with my low-end confidence numbers, only to ramp them up for my final call, which also needed another higher adjustment.
I will compare the final snow maps and my forecast maps below. Then, a few close-up region snow spotter reports from NWS and the list of snow totals below.
The current snowpack covers most of the region and has allowed the arctic air to settle in. So we will hold on a bit longer.
The official weather station at BWI has recorded nearly 50% of a normal winter snowfall this past week. If you recall my expectation for an above-average winter, think of this: In a Moderate to Strong El Niño Year, Baltimore has received 75% of the seasonal snowfall AFTER January 20.
BWI Snow Report
- 4.2” Snow on Friday
- 9.1” Snow For The Season
- 5” Snow On the Ground!

MY FINAL CALL
MY Thursday Night Suggestion
I realized the increase in snow expectations and posted this map with my report to suggest Harford and Cecil Counties in MD would be upgraded to a Winter Storm Warning…
It actually was expanded through central Maryland by NWS on Friday morning.
MY UPDATED FRIDAY MORNING
When it began, I posted my belief we would see overachieving results.
The Meso-Low formed as I suggested, which is why we ended up with a higher burst, longer duration, and more on the Eastern Shore.
I posed this question on my Facebook Page:
Was this an Overachiever or Under-Forecast? After looking at the final numbers, it was pretty close, with the tilt to the upside for many but not too far off.

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 when I need it and 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
