What happened

The episode as NWS ICT wrote it up.

A very strong low pressure system tracked out of the Rockies and marched across the Central Plains into the Upper Mississippi Valley. Further up in the atmosphere, a SW to NE directional mid-level jet was present along with impressive lapse rates. This setup was conducive to allow mixing of the extraordinary winds aloft all the way to the surface. As such, most areas to the west of the Interstate 35/135 corridor experienced historic straight line winds of 75 to 100 mph. Russell, KS recorded the highest gust of the day at 100 mph. All the while, Grassland Fire Danger Indices (GFDI) were in the catastrophic category for the same geographic area, and the Red Flag Threat Index (RFTI) yielded historical values for much of the same area. Once these record breaking winds were advected into Kansas, power lines began to fail and crash to the ground. Sparks began to fly as the lines toppled, and many wildfires were then set ablaze. Additionally, scattered thunderstorms and lightning in the area may have helped initiate fires. At this time, approximately 167,000 acres have been reported as burned across the state according to the Kansas Forest Service. The grandest of them all was the Four County Fire which engulfed much of northwest Russell and northeast Ellis counties along with smaller portions of Osborne and Mitchell counties. This Four County Fire comprised approximately 121,622 of those burnt acres which makes it the 3rd largest wildfire in Kansas since 2001 per the Office of the Kansas Fire Marshall. The communities of Fairport, Paradise, and Waldo were evacuated along with a portion of Luray for safety. Lastly, a convectively unstable atmosphere was present, and severe weather ensued as a line of severe thunderstorms developed across central and south central Kansas then rapidly moved to the northeast. This was the beginning of a derecho that not only affected Kansas but many states across the Upper Mississippi Valley. In fact, according to the Storm Prediction Center, the severe weather that occurred on the 15th set the record for the number of hurricane force (75+ mph) thunderstorm wind gust reports in a day (64) since 2004. This number of reports broke the previous record (53) of hurricane force (75+ mph) thunderstorm wind gusts in a day that occurred with the more well-known and publicized Corn Belt Derecho of August 10th, 2020.

.SHORT TERM...(Today through Friday night)
Issued at 254 AM CST Wed Dec 15 2021

Key Message:  A historic extreme wind event and extreme to possibly
catastrophic fire danger is set to occur today. High Wind and Red
Flag Warnings are in effect for north and south-central Kansas.

Southerly flow will usher in low level moisture return this morning
over central, southern, and southeastern Kansas. Should see cloud
cover linger over southeast Kansas today with the continued moisture
return. There will be a chance for severe storms this evening over
extreme southeast Kansas, however a very strong elevated mixed layer
will likely put a cap on any storm that attempts to grow vertical.

An absolutely extraordinary low level jet will set up over our area
today. Very warm temperatures in combination with extremely dry
conditions will allow for winds to mix down. ECMWF is showing 850mb
winds of 70 to 80 knots across our area and 700mb winds of 80 to 90
knots. Can't rule out 60 to 70 knot gusts for areas that mix out
well, particularly in north-central Kansas. Along with the winds
areas west of the Kansas Turnpike may see reduced visibilities due
to blow dust due to how dry it's been over the last month.

Things quiet down tomorrow behind the front with cooler temperatures
in place. Tomorrow and Friday will feel more seasonal but highs will
still be above average for this time of year. Could see some
moisture return tomorrow night into Friday that leads to light rain
over southeast Kansas.

.LONG TERM...(Saturday through Tuesday)
Issued at 254 AM CST Wed Dec 15 2021

Run to run consistency has been poor over the past few runs, but the
models seem to be in fairly good unison with changes in the extended
range. Trend today has been for a more zonal to slightly ridged
pattern for us towards the end of the weekend and start of the week.
This would keep temperatures above average, but nothing like what
we've seen the last week or so.

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 558 AM CST Wed Dec 15 2021

* High-impact, significant wind event today

An anomalously strong weather system will bring multiple aviation
hazards to the region over the next 12-24 hours. The initial concern
will be widespread low CIGs, which continue to fill in across
central and eastern Kansas this morning. Widespread MVFR conditions
will occur, with a brief period of IFR conditions possible. Low CIGs
should gradually mix/move out by this afternoon from west to east.

The primary hazard through this evening will be widespread 50kt+
wind gusts. It should be noted that this will be a widespread, and
very expansive, wind event with aviation impacts stretching multiple
states. Peak wind gusts could top 60kt, especially across north-
central Kansas. The strongest winds are expected from late-morning
through early afternoon. Given the recent stretch of dry weather,
the strong winds will likely be accompanied by blowing dust by mid
to late afternoon, possibly leading to MVFR, or lower, VIS at times.

Lastly, a few TSRA will be possible this afternoon across southeast
Kansas. If any TSRA develop, they will pose an enhanced risk of
downburst winds on top of the strong gradient winds that will be
occurring. The wind should quickly diminish by later tonight.

.FIRE WEATHER...
Issued at 254 AM CST Wed Dec 15 2021

An extreme to potentially catastrophic fire weather day is expected
today. Strong damaging winds will be accompanied with very warm
temperatures and very dry RH values into the teens and mid 20s west
of the Kansas Turnpike behind a dryline that will progress through
the region this afternoon. Fire weather values are maxing out over
north-central and central Kansas where all fire parameters are
present and in abundance. A Red Flag Warning is in effect for these
regions for most of the daytime hours today.

The progression of the dryline will determine how high the fire
danger will be for southeast Kansas. Due to how dry it's been and
how strong the system looks to be, we could see the dryline progress
faster than expected. In that case the potential for stronger winds
would progress east as well. Ahead of the dryline cloud cover will
likely remain, keeping winds and the fire danger down some. For now
we have decided to downgrade the Fire Watch for our two southeastern
rows of counties due to uncertainty in the position of the dry
line.
