Mesoscale bands of snowfall in New Mexico, Oklahoma and TexasGOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) showed a cutoff low that was moving slowly eastward across eastern New Mexico and the Oklahoma/Texas Panhandle on 28 November – 29 November 2020. This system was helping to produce rain and snow across parts of that region — and some elongated convective elements were evident across the OK/TX Panhandles. Snowfall totals included 2.5 inches in New Mexico and 3.0 inches in Texas, with 4.8 inches at Felt, Oklahoma (NOHRSC).
On the following day, a few north-to-south oriented mesoscale bands of snow cover were evident on GOES-16 “Red” Visible (0.64 µm) and Near-Infrared “Snow/Ice” (1.61 µm) images (below). Since snow is a strong absorber of radiation at the 1.61 µm wavelength, it appeared as darker shades of black on those images. Swaths of lighter snow cover melted rather quickly during the day.
