January 6 Snow Report and Grade My Forecast
The first snow event of the season was yet another partial event for the Mid-Atlantic. Like last winter, the impact was not for the urban areas, but it did produce snow and ice for the normal colder suburbs in the hills and mountains west and north.
My report here is to account for how much snow fell but also to allow you to grade my forecast. I believe I know where I was wrong and right, but the messaging is something I can always use feedback on.
Below, I will compare the National Weather Service Snow Spotter Maps to my forecast maps. The Poll feature is not working, so I am going to ask you to visit my Facebook page and comment there.
The funny thing is that I was overly cautious to talk about this storm until within one week, and even then, I refused to show the computer model maps with high snow amounts in central Maryland.
When I see the word BUST, I feel like it is meant as a middle finger for the forecast. After rereading my maps and words, many areas in the population center were not expected to get snow, so perhaps the ‘bust’ people wrote because it was their towns missing out?!?
Good News: Snow For Local Ski Areas
- Roundtop: 5 inches
- Liberty = 6 inches
- Whitetail = 6 to 8 inches
- Seven Springs = 5 inches
- Wisp = 4 inches
What went right:
- My First Call map was very close to varying for over 80% of our region.
- I emphasized the warm Bay temps and urban temps to bring the cities and I-95 wet roads.
- The heavy snow zone was verified.
What went wrong:
- The night before the storm, I saw air temperatures drop 2 to 3 degrees colder than expected.
- I looked at The National Weather Service extending Winter Weather Advisories farther east, and actually trended my totals in some areas higher to catch up to their totals.
- Low Pressure was closer with the pass by Maryland, and as a result, warmer air was pushed a little farther north. This changed inland snow to sleet and freezing rain sooner.

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.
