Stebo Posted July 7, 2014 Share Posted July 7, 2014 I think GRR might need to issue a tornado warning near Kentwood, they just went severe east of there but there is a pretty decent circulation there. Link to comment Share on other sites More sharing options...

tornadotony Posted July 7, 2014 Share Posted July 7, 2014 There's no excuse or defense for missing this completely, especially if it's the only severe storm in your CWA. Dual-pol tornado detection should be something browbeaten into anyone allowed to issue warnings. Link to comment Share on other sites More sharing options...

GRR_oopsies.png Yeah this isn't good, that circulation was apparent even going back further to the southwest, the hook barely had any reflectivity but there was certainly a circulation there. A bit similar to the Goodrich tornado back in June of last year which ended up being being a EF-2 Link to comment Share on other sites More sharing options...

xjcsa Posted July 7, 2014 Share Posted July 7, 2014 Local chase for me tonight; got some video: Happened to see some apparent rotation on radar and hit the road; found the right spot. Followed the tornado on the ground for about 30 minutes. No injuries, not much damage, spent basically all of its time over open fields. I did see a couple of porta-potties tipped over and some crop damage; that was about it. Link to comment Share on other sites More sharing options...

Looks like the core of the cell remained just south of the stadium, so things appear to have worked out. Did get a brief torrential downpour here from another weaker cell that had developed.

LOL...from the 2000Z Day 1 outlook: "LARGE HAIL AND DAMAGING WING GUSTS ARE EXPECTED TO BE THE PRIMARY SEVERE HAZARDS BUT AN ISOLATED TORNADO OR TWO MAY ALSO OCCUR."

Hoosier Posted July 7, 2014 Share Posted July 7, 2014 Based on the LSRs rolling in to GRR, sounds like it might've been a strong tornado in Kent county. Link to comment Share on other sites More sharing options...
Stebo Posted July 7, 2014 Share Posted July 7, 2014 Based on the LSRs rolling in to GRR, sounds like it might've been a strong tornado in Kent county. I agree especially in concert with the radar signature that Tony posted.

tornadotony Posted July 7, 2014 Share Posted July 7, 2014 Based on the LSRs rolling in to GRR, sounds like it might've been a strong tornado in Kent county. I can't recall a tornado off the top of my head that has had Z >60 dBZ in the debris signature and not been strong. Debris is not a Rayleigh scatterer, but both Mie and resonance scattering still have particle concentration N buried somewhere in their radar equations, so it makes sense that a stronger tornado that lofts more debris should have a higher reflectivity. And for some reason, it seems casually from what I've seen that 60 dBZ is a sort of threshold. I need to do more work on this in the future when I have time (ha!).

Honestly I don't think I have other than GRR, and what is the benefit of putting it in a severe warning. It will cause people to panic or get mixed messages, and if a tornado did actually occur there wouldn't be a tornado warning out to cover it.

Highly unlikely those type of winds and the subsequent damage came from straight-line winds (given the lack of MCS/cold pool organization) or a microburst (given the diminishing low-level instability).
