GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images with an overlay of GLM Flash Extent Density (above) covered part of a widespread winter storm event — which included thundersnow in parts of Nebraska, Iowa, South Dakota and Minnesota — that occurred on 03 January 2023. Areas that reported thundersnow experienced convectively-enhanced snowfall rates... Read More

Daily Full Disk imageryBy animating daily NOAA GOES-16 ABI Full Disk composite imagery, the year 2022 can be shown quickly. The GOES-16 loop below displays a 17 UTC image from each day of 2022 (the images are Rayleigh-corrected True Color RGB composites). This GOES-16 loop is similar to a loop... Read More

A sequence of GOES-16 (GOES-East) Nighttime Microphysics RGB and Day Snow-Fog RGB images (above) showed plumes of “ocean effect” clouds (including a “sound effect” cloud band, originating over Long Island Sound) that produced periods of snowfall from coastal Connecticut and Rhode Island (as well as Block Island) to Martha’s Vineyard, Nantucket Island and Cape...

GOES-16 (GOES-East) Day Snow-Fog RGB images (above) showed widespread horizontal convective rolls (HCRs) that were streaming southeastward across much of the north-central US — in the wake of a strong arctic cold front — on 22 December 2022. This HCR signature is often accompanied by significant blowing snow; in fact, many Interstate highways were... Read More
