The Storm’s Over — The Numbers Are In

The dry air was the wild card. Radar showed moderate snow over all of Connecticut for hours-and-hours before anything hit the ground.

Here are the final DOT numbers. I have also added the Boston and New York NWS snow totals, which include Connecticut, for the Dec 20-21, 2009 storm at the end of this entry.

I was right about Southeastern Connecticut getting the most snow followed by the shoreline in general. The snow was fluffy and windblown as predicted.
