The first storm of the year, and the winter season turned out the be the biggest a lot of our region has seen in many years.
This ramped up in the prior two days, and continued to impressed with thunder snow, blizzard conditions, hundreds of thousands without power, and highest snow totals in normally warmer southern and eastern areas.
Below are regional maps AND lists of snow spotter reports. But first, I wanted to compare the regional snow map to my Final Call For Snowfall.
Then I ask you: Grade My Forecast.
More local details and Delmarva map can be found below.
Notes:
The Good
Most of this forecast fit well, including my high snow zone.
I called less than the excessive model maps, but higher than The National Weather Service.
I know there were doubters, and even some of my clients kept asking this morning if it was going to happen. They were pleased.
The Bad:
My error was the north side. I knew there would be a sharp cutoff, but it was about 30 miles south of my forecast. Result: BUST for Frederick, Carroll, and Northern Baltimore to Harford Counties.
Grade My Forecast For Snow: Jan 3 2022
Cecil, Harford, and Baltimore Counties: Here we see that sharp cutoff!
Notice the spread across Baltimore from north to south!
Here we see that sharp cutoff in the region that normally gets more snow NorthWest Baltimore and Carroll County.
Big winner from Annapolis and southward.
Anther Big Winner
Another Big Winner
This is where we can see the edge of the heavy snow.
Here we see that sharp cutoff just before Frederick and Mt. Airy- also areas that usually get more snow.
There were some very big totals in interior sections, with a few places in Delaware over 1 Foot!
Snow did finally stick at the beaches later in the day.
