Station's five snowiest calendar days (OBSERVED, NOAA ACIS)
Click a station for its 10 biggest storms. Snowfall overlays: one storm per city at a time. On at load: each city's highest-ranked storm with a NOHRSC analysis: New York #1 (2016), Boston #5 (2013), Chicago #3 (2011), Buffalo #2 (Dec 2022). Boston's #1–#4 storms predate the analysis, which begins in late 2008. Each city's snowfall is shown on its side of the grey lines midway between the cities' stations; the storms reached beyond them. Also in the menu, off at load: NWS warnings (ALERT, IEM) for the 15 storms since 2006 (none on file for earlier ones); NWS storm reports (OBSERVED, zoom 7+) for 13 storms (2010–2026); observer snow totals (OBSERVED, NOAA ACIS, zoom 6+) for 22 storms with no NWS snowfall amounts (1947–2015); NEXRAD radar at the station's heaviest snow for 11 storms (1995–2026). Connecticut counties on the 2026 storm reports: NWS county; Census uses planning regions since 2022.
