Tuesday Morning Update
This is our Thanksgiving Travel Storm Day. Rain will be spreading in during the late morning and early afternoon across metro areas. It has already started farther west. There is ‘just enough’ cold air in the high mountains that Frostburg to Garrett County may have some icy roads.
This storm will bring heavy rain tonight and possible thunder, as well as coastal flooding around the Chesapeake Bay. The entire system will be moving away Wednesday morning leaving us quiet for Thanksgiving.
Weather Alerts
A Winter Weather Advisory includes Garrett County, Maryland, and parts of Allegany County near Frostburg. This is for light snow or icing until 1 PM.
A Coastal Flood Warning is in place for Anne Arundel County. Winds from the East may raise water levels over 1 Foot for places like Annapolis.
Coastal Flood Advisory for the lower Chesapeake Bay.
Morning Temperatures
We have a chilly start, but the areas below freezing are limited to the highest elevations near Garrett County in Western Maryland.
Morning Surface Weather
This is called a Double-Barrel Low Pressure as there are two distinct centers. This will push in steady rain today, and heavy rain overnight.
There are pockets of sleet and flurries at the start, but any risk of icy travel will be confined to the mountains.

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.
