Persistent snow cover in Oklahoma and Kansas
A toggle between NOAA-20 VIIRS True Color and False Color Red-Green-Blue (RGB) images (above) showed a patch of snow cover that remained across parts of northwestern Oklahoma, the Oklahoma Panhandle and southwestern Kansas on 08 December 2020. This was residual snow cover from a winter storm that occurred 6 days earlier (on 02 December — NWS Amarillo | NWS Norman | NWS Dodge City | NOHRSC total snowfall).The GOES-16 (GOES-East) Land Surface Temperature (LST) product at 1900 UTC (below) displayed LST values in the 30s F (shades of cyan to blue) over the patch of snow cover, in stark contrast to LST values in the 60s F (shades of green) across adjacent areas of bare ground.
GOES-16 Mid-level Water Vapor (6.9 µm) images (below) included plots of hourly surface weather type as the middle-tropospheric low responsible for the winter storm moved slowly across the region on 02-03 December.GOES-16 Mid-level Water Vapor (6.9 µm) images, with plots of hourly surface weather type [click to play animation | MP4]
