Meteorologist ClicheVortex2014 Posted May 12, 2022 Meteorologist Share Posted May 12, 2022 (edited) Definitely not surprised to see the entire northern part of the derecho being tornado warned. Warm front does wonders. Won't be surprised to see this extends to the east as the derecho approaches the warm front.

Meteorologist ClicheVortex2014 Posted May 12, 2022 Meteorologist Share Posted May 12, 2022 (edited) You can see the intense winds coming in and wrapping around from behind the MCS in northern SD on some reflectivity bands and velocity. Definitely some pretty streaky reflectivity bands. Edited May 12, 2022 by ClicheVortex2014 Link to comment Share on other sites More sharing options...

Meteorologist ClicheVortex2014 Posted May 13, 2022 Meteorologist Share Posted May 13, 2022 Will be interesting to see where this compares to historic derechos. Would be insane to have the most intense derecho on record, in any month, just 6 months prior to another top-5 derecho. Link to comment Share on other sites More sharing options...

Meteorologist ClicheVortex2014 Posted May 13, 2022 Meteorologist Share Posted May 13, 2022 In case the derecho isn't enough, a secondary MCS is taking care of the rest of the warm sector that wasn't savaged by the derecho. This is in extreme SE SD/NW IA/SW MN. 70 mph winds moving NE at 60 mph 1 Link to comment Share on other sites More sharing options...
Meteorologist ClicheVortex2014 Posted May 13, 2022 Meteorologist Share Posted May 13, 2022 52 unfiltered/42 filtered significant wind reports. We certainly just witnessed a top-5 derecho in terms of magnitude. Possibly top 3. Link to comment Share on other sites More sharing options...
