Derecho! Posted May 20, 2013 Share Posted May 20, 2013 Wha? KFOR: Moore Tornado was 2.25 miles wide I think that was the width of the debris ball, which may well have been larger than the tornado itself. Link to comment Share on other sites More sharing options...
Ed Lizard Posted May 20, 2013 Share Posted May 20, 2013 Judging from KFDR radar, I think the dryline near there is retreating somewhat, which would seem to increase chances of repeat storms. It seems to me things are usually quieting down when the dryline retreats, but it seems early in the day. Link to comment Share on other sites More sharing options...
baroclinic_instability Posted May 20, 2013 Share Posted May 20, 2013 I think the threat will gradually shift into N TX and far southern OK along the Red River as low level helicity begins to ramp up as the low tightens then retreats west...setting up an isallobaric response in the low levels to the impinging upper level speed max moving in from the intermountain W.

The Great Zo Posted May 20, 2013 Share Posted May 20, 2013 The TDWR was really in the perfect spot capturing the evolution at 1min intervals. Easily the most impressive reflectivity I've seen from a permanent standing radar. This is remarkable imagery. I am most intrigued with the life cycle as the storm neared, crossed, and then moved away from I-35. Near the start of the loop, the signature is that of a classic hook / debris ball. As the storm neared I-35, the signature becomes much more messy. I don't know that you're actually looking at a 2+ mile wide debris ball (as was reported on some TV stations) -- the aerial footage seems to confirm that the tornado was becoming obscured by precipitation at that point in its evolution. The circulation (seen on velocity imagery) remained much tighter than the large area of 50+ dBZ on reflectivity. However, after it moved past the interstate (roughly 2025Z), everything becomes much better defined again -- both in the helicopter footage and on the TOKC radar images. Multiple radar bins over 65 dBZ in the debris ball for several consecutive scans. Velocity images from TOKC showed a very common signal seen in tornadoes on TDWRs -- dealiasing failures at the center of each lobe (inbound / outbound) of the circulation.

CNN states via KFOR reporter that they are still searching for the 3rd grade class that was in the hallway... completely destroyed area around them... 4th to 6th grade students all accounted for... this is at Plaza Towers Link to comment Share on other sites More sharing options...
ICEHOCEY77 Posted May 20, 2013 Share Posted May 20, 2013 I think the threat will gradually shift into N TX and far southern OK along the Red River as low level helicity begins to ramp up as the low tightens then retreats west...setting up an isallobaric response in the low levels to the impinging upper level speed max moving in from the intermountain W. Agree, the lone show going right now is the cell in TX. The cell east of Wichita Falls is in the best environment right now. Just went tornado warned.
