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 of 2-3 inches per hour; storm total snowfall amounts were as high as 27 inches in southeastern South Dakota and 18 inches in northeastern Nebraska (NWS Sioux Falls event summary | WPC storm summary).
Ahead of the cold front associated with this winter storm (surface analyses), severe thunderstorms produced tornadoes, large hail and damaging winds (SPC Storm Reports) from the Upper Midwest to the Deep South. Overlapping GOES-16 Mesoscale Domain Sectors provided imagery at 30-second intervals over parts of Mississippi, Alabama, Georgia and Tennessee where some of the severe weather occurred — “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images that include time-matched plots of SPC Storm Reports are shown below. With some of these thunderstorms, pulsing overshooting tops exhibited infrared brightness temperatures as cold as -70 to 75ºC.

By animating daily NOAAGOES-16ABI 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 that includes the Solstice-to-Solstice dates.
One GOES-16 ABI image for each day of 2022. Click to play mp4 animation.
A link to the mp4 animation above is available here (other versions: small, medium). It should be noted that all these images are drastically sub-sampled from the full spatial resolution data.
A similar year-long animation, on an interactive web page, from GOES-16 at 17 UTC on each day is shown below. This time was chosen for a maximum illumination of the full disk viewed by the satellite.

A classic winter weather pattern developed over the Pacific Ocean this week setting the stage for significant drought relief for the western U.S., along with heavy to excessive coastal rains and mountain snow measured in feet for the Sierras and Rockies.

Even though this is a “classic” winter pattern, it hasn’t been prevalent during the past few winters. The absence of this weather feature is part of the reason why much of the western U.S. is experiencing severe to extreme drought.
An Atmospheric River pattern is expected to persist into January 2023 with many areas becoming hydrologically sensitive to additional precipitation. Concerns for flooding and/or mudslides are heightened in western locations with burn scars from recent wildfires.
The persistent AR pattern is reflected in NOAA’s CPC Precipitation Outlooks:
