Final snowfall totals from November 7-8, 2012. Click here for full-size image

An impressive autumn nor'easter dumped heavy snow across the state. A few areas picked up more than one foot of snow from the storm.

Event summary:
A light wintry mix of precipitation moved into southeastern Connecticut on the morning of November 7th. The precipitation quickly overspread the state from southeast to northwest. Most areas outside of lower New London County began as snow as stayed as snow through the duration of the event.
Temperatures fell into the mid and lower 30's and by midday several locations had already reported an accumulation of snow. Bands of moderate to heavy snow set up across central and southwestern Connecticut during the afternoon. These bands were quite persistent and snow piled up.
Conditions rapidly deteriorated during the evening commute as heavy snow was falling along sections of the Merritt Parkway, I-95, Route 8, I-91 and I-84. Some of the locations hardest hit included the Naugatuck Valley as well as New Haven and its northern suburbs.
Snow tapered off to periods of light snow and snow showers after midnight, but some spots picked up an additional light accumulation of snow on the morning of November 8th.

Final snowfall totals:
A stripe of roughly 8 to 12 inches of snow was reported near and just southeast of the I-84 corridor. Totals decreased as you moved northwest and east of that area. Communities along the shoreline in New London County received little if any snow accumulation.
An official report of 13.5 inches came in from Nicholas DiGiovanni in Clintonville.
Totals in surrounding areas line up with this report, including 12.0 inches in Hamden, 12.0  inches in North Haven, and multiple reports of 12+ inches in Wallingford.
A second bulls-eye centered over sections of the western Naugatuck Valley.
Another report came in from the National Weather Service (NWS) of 13.5 inches in Monroe. Reported totals in adjacent towns came in with 13.0 inches in Oxford and 13.0 inches in Shelton.

The map is compiled of reports from NWS offices in Albany, N.Y., Taunton, Mass. and Upton, N.Y., as well as totals sent in directly to and Storm Team 8 meteorologists.

I personally recorded a final total 9.0 inches in Naugatuck and measured 7.0 inches in downtown New Haven shortly after 11 p.m. on November 7th. There was still several additional hours of accumulating snow after that point.

***If you have a total that does not coordinate with this map, let us know.***

Keep in mind that several factors may lead to differing amounts. The fact that snow ended during the pre-dawn hours on November 8th meant that some melting and compaction likely occurred for those who measured the snow depth later that morning. Also, the banding nature of the snow led to highly variable snowfall amounts, even within individual towns.

As a final note, the totals represented in the map are smoothed and approximate.
