Southern Connecticut received a heavy snowfall on the 11th and 12th of January from surface low pressure tracking up the Atlantic seaboard and then rapidly intensifying as it tracked just southeast of Long Island in response to an intense upper level disturbance.
Light snow overspread the region Tuesday evening ahead of low pressure and then became heavier Tuesday night as low pressure rapidly intensified. As the upper level disturbance worked over the region late Tuesday night a semi-stationary north to south band of very heavy snow developed just east of the Hudson River, gradually pivoting northeast Wednesday morning through early Wednesday afternoon. This band was responsible for snowfall rates of 3 to 4 inches per hour, and snow totals of between 15 and 30 inches across Southern CT by Wednesday afternoon.
The highest snowfall totals were observed across northern portions of Fairfield and New Haven Counties. The Governor of CT, Daniel P. Malloy, was cited as saying, ���that the season's second major storm was a record-breaker, dumping more snow on Connecticut in 12 hours than the state had ever seen in a full day, up to 30 inches.

A partial roof collapse occurred at a multi-unit apartment building at 92 Washington Street in Norwich, CT at 10:53 am on Wednesday. No one was injured, but 10 people were displaced. The collapse was due to roof rafters on the nearly flat roof giving out under the weight of heavy snow and ice. The roof partially collapsed, causing the rear wall to bulge and for the building's chimney to lean towards an adjacent building.
