5/24/2010 NOW: SD/ND/NE/CO/KS

[Derek Weston]

Tornado warned cell just north of Kimball Nebraska. Decent couplet at times. Racing north near 60 mph.

Well today can be summed up in a quote from anchorman: "That escalated quickly"
These storms have fired super quickly and are quickly racing to the north. The cell closest to the GLD radar site bears watching in my opinion. I think there is some upper level rotation on it.

 

[Michael Riedl]

By the looks of latest SPC MD we might have WW's from the Mexican Border to Canadian Border. Quite the widespread severe threat.

Storm near Woods, KS (NNW of LBL) has both rotation and a developing hook. It is also slightly more of a right-mover than the other storms.

Andy Gabrielson is streaming a large tornado near Plainview, SD. Storm seems to be cycling with a very strong couplet, and due north motion.

Doppler indicated tornado warning north of Grand Forks, ND. I can see this cell from my tall house and it looks elevated but it did have a nice scud bomb about 10 minutes ago.

The 18z LBF sounding didn't show very strong deep-layer shear, with 50 kts near 1.2 km AGL and 60-65 kts near the tropopause. So, despite the strong flow aloft, the very strong low-level flow (30-40 kt sustained with gusts to 50 kts) is yielding deep-layer shear that isn't terribly impressive (at least near where the LBF sounding was launched). There is now a very strong push with the DL/front in western NE and zippering down into northwestern KS, so we may see rapid evolution to squall line in those areas. I'm actually surprised a bit that the cells in northwestern NE stayed semi-discrete so long. Farther to the south, mid-level is more veered, so it should be more chaser-friendly in terms of storm motion and deep-layer shear vector orientation relative to the dryline.

ICT TDWR indicates 65 kt. or greater winds in eastern Harper and southern Kingman Co. at 9:36pm Central. These storms will be moving into Metro Wichita during the next hour or so.

UPDATE: LSR 9:32pm, power poles snapped along K-42 SW of ICT.
