Quincy Posted April 23, 2014 Author Share Posted April 23, 2014 Although the threat today may not be a particularly impressive one, it still looks like there is a narrow corridor from the Texas panhandle into western OK/KS that could light up this afternoon/evening. The 12z sounding from Dodge City shows some decent veering and a low-level jet up to just about 60 knots (59kt at 850mb). The obs around southwestern Oklahoma showed 10m winds backed to SE/110°. While the tornado threat is low, the focus appears to be localized in this area, near the eastern TX panhandle and adjacent OK. Link to comment Share on other sites More sharing options...
LocoAko Posted April 23, 2014 Share Posted April 23, 2014 I wonder if tomorrow there will be the first storm reports west of (or near) Dodge City for the whole year so far. Just a reminder that the KDDC radar is currently out of service. Link to comment Share on other sites More sharing options...

Hvward Posted April 23, 2014 Share Posted April 23, 2014 Developing tornado near Wellington, TX. Watching it on the chaser cams and it is coming together very quickly. 3" hail accumulation being reported. Link to comment Share on other sites More sharing options...

Stebo Posted April 23, 2014 Share Posted April 23, 2014 There is a decently strong circulation associated with that storm from FDR's radar, but the radar beam is hitting the storm at 6500' so you aren't getting the best representation compared to what might be happening near the surface.

Chinook Posted April 23, 2014 Share Posted April 23, 2014 Finally the storm near Wellington TX, is taking on a supercell type shape with several knots of rotation seen (as noted by Stebo). Previously it looked like a big, tall hulking mess with 3.75" hail detected, the hail reported was 1.50" in diameter (about a half hour ago.)

Jim Marusak Posted April 23, 2014 Share Posted April 23, 2014 the storm near Vinson, OK is looking quite nasty from 0.5 (6kft) and 3.5 (18kft) levels. i did see a lot of chasers with it. but hopefully this multi-tilt will help the perspective for home gamers.

I'm sure there is a reason, but I can't say that I know it offhand. Might be a cool thing to look into one day.

Sluggerwx-- I also noticed that the cell that moved into OK had 73.5 dBz on AMA radar a few mintues ago. That has to be about the most you can see on the Level3 nexrad data.

I bet the cells up in southern Kansas are really picturesque. Those ones are a little more isolated than the Texas/Oklahoma storms. It's a shame the radar is down there.

First time I've seen folks using MPing south of the boarder. gr2analyst 2014-04-23 18-43-49-31.png i'm sure as long as it goes by the specific GPS coordinates instead of direct international boundaries, i'm not surprised. and it actually is good to know such a database can be started outside the US. I hope Canadians near the US border will also use it, especially in southern Ontario, southern Quebec, NB, and western NS where it's decently covered by the Buffalo, Detroit, Burlington, Caribou, and other radars.

It is mostly dark, with some light in the west. Barely a raindrop. I guess that's what you get with a dew point of 30 or whatever.

bdgwx Posted April 24, 2014 Share Posted April 24, 2014 The volume rendering of the Throckmorton cell is impressive...lots of high returns in the hail growth zone (my color table uses white starting at 60 dbz). Link to comment Share on other sites More sharing options...
Quincy Posted April 24, 2014 Author Share Posted April 24, 2014 Texas and Kansas got hit the hardest yesterday, but the Wellington, TX cell that crossed over into OK did look pretty impressive at first. There were plenty of chasers on that one:I encountered varying sizes of hail up to about dime/nickel (estimated because there was torrential rain at the same time.) Winds were varying, but were not particularly strong until one point in Sentinel, OK. Here the wind was strong enough to fling a trampoline across the road: Link to comment Share on other sites More sharing options...
