12/15/21 Midwest Severe

While not PDS, still pretty high end for a TOR Watch...
No doubt about it! For reasons such as this:

Severe Weather Statement
National Weather Service Hastings NE
147 PM CST Wed Dec 15 2021
Clay NE-Adams NE-
147 PM CST Wed Dec 15 2021

...A TORNADO WARNING REMAINS IN EFFECT UNTIL 200 PM CST FOR WEST
CENTRAL CLAY AND SOUTHEASTERN ADAMS COUNTIES...

At 147 PM CST, a confirmed tornado was located near Ayr, or 14 miles
south of Hastings, moving northeast at 75 mph.
 
The line of storms already coming in 75 to 85mph winds reported on SPC storm reports. I think the biggest story will be this becoming an extreme derecho event. Tornadoes yes, but the sheer widespread wind damage will likely be top story on this.
If the line is moving at 55-70mph, won’t that make the already strong winds worse??
 
Looks like there's a quite a bit of CIHN across IA.

While the line should easily break the cap, the CIHN may be the saving grace that prevents more tornadic supercells from developing ahead of the line.
 
If the line is moving at 55-70mph, won’t that make the already strong winds worse??

Yeah that can enhance already ridiculously strong downward momentum from the convection.

Speaking up, already more solid 80 to 85mph wind gusts reported. Russell, KS just had a 60 mph sustained gusts to 84mph. Another report from KS reported a metal basketball pole was broken/bent in half by strong winds.
