April 26th Severe Weather


Chicago Storm

Recommended Posts

Prelim rating of EF2, check in the 4/25 thread.

Also, something still seems a little off with the low-level mesocyclones of these supercells. We might still have to wait a couple hours before the real threat begins...

Yeah I noticed this too. Granted, I haven't looked in enough detail to tell what, other than the parameters I guess are just more favorable a bit later on.

I feel like it's the deceleration of low-lvl flow invof the boundary. This happened on May 1st last year too, it took several hours before supercells were finally able to produce destructive tornadoes over MS-TN. There was another event recently where that was the case too. That phenomenon has to be examined more.

Anyway, back to today's focus. Just something that I wanted to point out. My mind's been incepted with the idea for some time now.

Seems like the dry line may be retreating west and north near DFW. I'm in Ft. Worth and in the last hour the hi cloud tops have formed in every direction around me but NW. Am guessing storms will fill in over much of the Metroplex, hopefully without the tornadoes.

North winds and dewpoints in the low 60s- the upper disturbance approaching was strong enough to generate severe hail in the Panhandle with low 40s dews.

I suspect DFW will see elevated storms if storms do develop.

possible debris ball NW of shreveport

Looks just like a regular hook echo. Circulation not tight enough for a tornado on the ground that would be capable of producing a debris ball at that scan height. The hook echo to the SW however looks more promising at the moment.

Not a single one of the warnings around Shreveport has been anything other than radar-indicated, and there are no LSRs with a tornado at this point.

just becuase they aren't in the LSR doesn't mean they didn;t happen...LSR are often delayed

The on air met said their spotters had a tornado on the ground

I'm starting to see a line forming to the NW of Indy, each refresh of the radar extends it just a bit further southwest towards the IL border.

Though it looks like it's forming quickly, any chance the Indy metro area will see anything truly severe or is it getting started too close to us?
