Here are some snowfall maps that I created using reports from various sources. Many of the reports came from this forum and the National Weather Service. Only social media reports that passed through quality control were considered.

Light snow overspread the state from southwest to northeast shortly after midnight on February 5th. This was ahead of a low pressure system that was moving into the eastern Ohio Valley. The snow quickly became heavy at times around daybreak, with snowfall rates of 1 to 3 inches per hour. A gradual change to sleet and freezing rain also took place through the morning from south to north. Warmer air flooded in aloft, although there was a cold layer that was very slow to erode near the surface.

Around midday, there was a break in the action with just some spotty drizzle and light mixed precipitation. The shoreline and parts of eastern Connecticut did briefly rise above freezing. A glaze of ice was observed between I-95 and I-84, with the most significant icing across the climatologically favored sheltered areas of Fairfield and New Haven Counties in the vicinity of Route 15. An inch of sleet was reported in many areas and the size and intensity of sleet that I observed was the most impressive I can ever recall.

During the afternoon, colder air moved in as a secondary low developed just south of Long Island. Precipitation ended as a few snow showers on the night of the 5th, with a few flurries into the early morning hours on the 6th across eastern Connecticut.

Snowfall totals between 8 and 10 inches were common. Somewhat less snow fell along the immediate shoreline and in eastern Connecticut. The higher totals were around a foot across central and northwest portions of the state.
