1-minute Mesoscale Domain Sector GOES-16 (GOES-East) Day Cloud Type RGB images (above) displayed narrow bands of glaciated (brighter shades of green) clouds that produced snow squalls as they moved eastward across western and central Pennsylvania on 10 March 2024. Periodic lightning activity — denoted by blue GLM Flash Extent Density pixels — was seen with some of these snow squall bands.

The Pittsburgh and State College NWS forecast offices issued numerous Snow Squall Warnings for these features.
