Thursday February 11 2021
I am so happy to report that this storm ending this morning produced snow for many areas that have missed out on recent events. I am also happy since it worked out for about 90% of my call. It was even sweeter paying close attention to the north Bay coastal area and they hit their target. No BUST there!
The “GRADE MY FORECAST ” poll is below.
I have many local snow maps and spotter lists to show you. Snow covers most of our region, and I wanted to start with this one map (but it might be hard to see).
McHenry in western Maryland has 26” of snow on the ground, according to Kristin Skewis.
In Dover, DE my mother in-law measured 6” of new snow today as one of the top spots.
Annapolis
The state capital received just under 2 inches, but it was enough to change the landscape and break the snow drought bubble
Even just an inch or so of snow is enough to make Annapolis look spectacular! #FITF ❄️ ❤️ https://t.co/bXp4zc4AhM

This was originally expected to be a two part event, but this first part verified my original call and the follow up maps. I will show all below.
The second part is passing through southern Delmarva tonight, so I will update that region when it is complete. We have a busy pattern ahead, so I wanted to post this report so we can get focused on the ice storm on the way.
