Wind & Dust:

Widespread damaging winds occurred across all of central and southern Kansas, including wind gusts as high as 70-100 mph. For a complete listing of the peak wind gusts, please check out this Public Information Statement. In addition to the wind, widespread blowing dust developed thanks to the very dry conditions of late.

As a powerful storm is currently sweeping through the Plains, the #GOES16 ðŸ›°ï¸ watched it sweep up dust as winds gusted ~80-100 mph in some places.

Fire:

Numerous grassfires developed from western into central Kansas including a very large fire across north-central Kansas (Ellis and Russell counties).

Radar Loop

A line of strong to severe storms developed throughout the afternoon and evening moving across central, south central, and southeast Kansas. While multiple severe wind gusts were measured in association with these storms, many of the days strongest observed wind gusts were not associated with the line of storms.

Environment & Science

An anomalously strong storm system moved out of the Rockies and raced across the Central Plains, bringing numerous hazards to much of the Great Plains. This event is noteworthy because of how unusually strong it was, especially for this time of year. The maps below show the environment the led to this impactful event.


3pm 500mb Plot. Shows the upper level storm system that was moving across the Central Plains. Note the unusually strong, 120kt winds over Kansas (known as the mid level jet).	3 pm Surface Map. This shows the location of a strong surface low, and associated dryline. The dryline raced east-northeast across western and central Kansas, accompanied by a narrow line of thunderstorms and very strong winds.	3 pm Surface Map and Jet. Strong winds aloft overspreading a very dry airmass allowed for the rapid spread of grassfires that developed from western into central Kansas. This is a dangerous fire weather setup, known as a fire outbreak setup.


3 pm Surface Map and Lapse Rates. Steep lapse rates help stronger winds aloft to mix down to the surface. The steeper the lapse rates, the higher into the atmosphere the winds can be tapped into.	3 pm Surface Map and MLCAPE. MLCAPE is a measure of instability. The area outlined in red shows a narrow zone of unstable air ahead of the dryline. This combined with a weakening "cap" allowed a line of thunderstorms to develop.	3 pm Effective Shear. Shear is what allows thunderstorms to organize and potentially become severe. Higher values, like with this event, often lead to a higher risk of severe thunderstorms.

Topeka's sounding came in late and they nailed this one. Shift the scales, it's an all-time record by a mile. 82 kt wind at 850 hPa is absurd for any time of year. Beats all >48,000 soundings in this record. pic.twitter.com/LNLs7Z5hyT — Ryan Stauffer (@ryans_wx) December 16, 2021
