Severe Weather 4/17/26

Yeah. I'm getting readings on GRAnalyst of SRV winds near 140mph about 1040 ft above ground level west of Emden, IL

South of Columbia, MO (near Russellville) could be a strong tornado ongoing. Hate that radar hole

Again, with the distance from any radars, it's a little hard to tell if any cycling has occurred, but I think the storm's been maintaining a decent couplet for >20 miles.

EDIT: what @Kds86z shared above ^

Illinois lighting up with observed TORs down the line now

I wonder who is actually observing these TORs. It's dark, and that's a big line of thunderstorms with any spin-ups being quick and probably weak.

I've lived in the Peoria area for over a decade and that's basically like 80% of our tornado warnings back then, which is why a lot of people there just don't take them as seriously as over here in supercell-infested Tornado Alley.

Looks like it says radar confirmed
 
I'm still pretty sure the Marathon county storm was long lasting if not long tracked. It only appeared on CC later in its life as it was far from radar (and probably rain wrapped).

Is there a reason not as many long tracked tornadoes this year overall?

Just conjecture on my part here; pattern has been active (unlike 2018) but all the trough ejections have had issues with structure/orientation (energy coming out piecemeal/positively tilted) that is sub-optimal for long-track, cyclic, classic warm sector supercells.

SPC has caught a bit of flack (understandably so, IMO) for the way the rollout of the CIG hatching system has been implemented (lots of 2%+CIG1 days), but they have done well by holding back from tornado-driven MDTs on days like today and Tuesday when looking at the parameter space alone would have supported it. Perhaps a lesson learned from last year April 28 (although in all cases this week the CAMs were much more supportive of at least *some* supercell activity than they were for that day).

As exemplified by the post above, we've definitely had some significant tornadoes today, but there were also some definite factors that were apparent in the model data that made a really high-end outbreak unlikely.

Thanks, definitely a pattern thing it seems. After last year we need a break from destruction.
