Lake effect snow in Kansas

A sequence of Tulsa radar 0.5-degree base reflectivity images at 30-minute intervals (from 0700-1800 UTC) showed the lake effect bands streaming southeastward from those 2 lakes — followed by a toggle between Suomi-NPP VIIRS True Color and False Color RGB images at 1903 UTC (below). A northwesterly flow of cold arctic air (in the teens to single digits F) across the still-unfrozen water of the lakes picked up enough moisture to create narrow cloud bands that produced the accumulating snowfall.
