Heavy Snow — Northern Middlesex, Connecticut

2023-02-27 to 2023-02-28 · Northern Middlesex, Connecticut

Event narrative

Heavy snow was reported across the northern half of the county into the morning commute. A trained spotter reported 6.1 inches in Cromwell, and a Cocorahs observer reported 5.0 inches in Higganum. Some compaction likely took place with these reports as they came in well after the steadier snow ended as temperatures were marginal and close to freezing and then rose above freezing.

Wider weather episode

Weak high pressure and a marginally cold air mass was locked into the northeast with blocking to the north across Eastern Canada, while low pressure over the Midwest moved east and redeveloped off the Northern Mid Atlantic coast. This led to the first widespread accumulating snowfall across the CWA.
