Friday December 5
Afternoon Update
This little weather system has been a big headache even though it didd perform almost exactly as expected. The light snow created road problems across parts of Central and Southern Maryland today. Snow totals are preliminary, but the map and list below match very well with my forecast.
The next phase is just evidence that this has been trying very hard to max its potential. The Coastal Low will get a little enhancement tonight, allowing for a band of light freezing rain or drizzle to form. This will be in addition to wet pavement that will freeze with the cold temperatures.
The National Weather Service has posted A NEW Winter Weather Advisory for Maryland and Virginia for a glaze of ice. I see support that Delmarva and metro Philadelphia into New Jersey should watch closely for the possibility they get their own Advisory as well.
Low Pressure on the coast near Wilmington, NC will strength just enough to work with High Pressure in the Atlantic to increase the flow of moist air onshore.
The upper level dynamic support a band of light freezing rain or freezing drizzle to develop this evening and overnight.
5 PM Fri to 5 AM Sat
(This model performed best with today’s snow)
5 PM Fri to 5 AM Sat
Do You remember the decade of first snows on this date? It was also how Faith in the Flakes began with my son.

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 can also 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
