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.

A clipper system that gave way to a coastal low just south of Long Island resulted in generally 2 to 4 inches of snow across the state. There were a few localized totals of just over 4 inches, but there were no reports over 5.0 inches. The highest totals were across the higher terrain, where some modest orographic enhancement and/or higher snowfall ratios may have come into play. There was a "snow hole" in southeastern Connecticut where generally 2 inches or less was measured. A few of the higher resolution models hinted at this area of localized lower amounts, but most data pinned that area further north.

Snow flurries developed around daybreak on December 17th and periods of light snow continued through midday. After a break in the action, an area of moderate to locally heavy snow formed by mid-afternoon as low pressure intensified just to the south. Snowfall rates approached one inch per hour for a time. Some warmer air worked north and there was a change to sleet and freezing rain cross portions of lower Fairfield County. Snow tapered to flurries during the evening hours.

If any amounts you reported conflict with these amounts, please comment back with your total(s).

Here is an alternate black and white version of the map:
