Low pressure passed just south of Long Island and brought heavy amounts of precipitation to the state. Snow changed over to sleet and then rain before ending.


Snow moved into southwestern Connecticut on the afternoon of December 26th between 3 p.m. and 5 p.m. The snow come down hard relatively quickly.
The snow overspread the state from southwest to northeast.
Temperatures were near freezing along the coast and in the upper 20's to lower 30's inland, so snow began to accumulate on most surfaces.
Precipitation changed over to sleet and then rain, first along the shoreline.
Most coastal areas had changed over to plain rain by 9 p.m. and at the same time sleet and pockets of freezing rain had made it as far north as I-84.
The majority of the state changed to rain by midnight.
Some of the northeast hills hung onto a wintry mix. The precipitation became scattered and light after midnight as temperatures slowly rose through the 30's.
The storm also featured strong winds and moderate coastal flooding.


Snowfall amounts along the immediate shoreline were generally less than 2 inches. Further inland, to roughly the I-84 corridor, between 2 and 5 inches of snow was recorded. Portions of northwestern Connecticut received between 5 and 8 inches. There was one report of 8.6 inches from North Granby, but that total was matched with an inconclusive total of 6.0 inches from Granby.

Here is a sample of the highest official reports from the National Weather Service:

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 WXedge.com and Storm Team 8 meteorologists and reports shared via social media.

I personally recorded a final total of 4.0 inches in Naugatuck. When I left New Haven shortly before 6:30 p.m., just over 1 inch had accumulated.

***If you have a total that differs substantially from the map, let us know.***

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

The next slide has a few more graphics from the event.
