5-minute CONUS Sector GOES-19 Mid-level Water Vapor images (above) showed the evolution of a large and intense Nor’easter that produced as much as 37.9 inches of snowfall in Rhode Island (a preliminary State record) and wind gusts as high as 84 mph in New York (WPC Storm Summary) during the 22-23 February 2026 period.

A slightly closer view using 1-minute Mesoscale Domain Sector GOES-19 Mid-level Water Vapor images (below) included overlays of GLM Flash Extent Density and GLM Flash Points, along with plots of surface weather symbols and peak wind gusts. Intermittent GLM signatures near the coast (or slightly inland) suggested that some brief thundersnow may have occurred. (Note that there was a brief outage of GOES-19 imagery on 23 February.)
