4/24/2008 NOW: CO, KS, NE, OK, TX, IA

[Tony Laubach]

First cell of the day severe warned about to cross into Kansas near I-70. Low beginning to really back the winds along the interstate and should starting pulling the higher dews back in that area over the next hour or two. GR showing a meso wwith this cell ATTM. Not targeting that storm, but moving in the northerly direction.

Heading back west to WaKeeney from Hays. Tornado watch should be issued for northwestern KS/southwestern NE here shortly. Expecting further cell initiation in the Colby/Atwood/WaKeeney area in the next half hour to hour or so.

Sitting here in Kingman, KS with clear skies. Im basically right on the dryline with the next wave of energy coming in a couple of hours I hope. Currently 78 over 64.

I initially said I was in Pratt. I meant to say Kingman.

SevereStudios Chaser Kory Hartman is just east of Atwood, KS right now on the Severe Warned cell north of Colby, KS. Roger Hill is also on the same cell. Cell had a nice overshooting top and is showing 67.5dbz returns.

Cell coverage isn't the greatest up in that part of Kansas, but Kory has been streaming video all afternoon as much as he can.

Vis showing nearly clear skies from I-70 south at 2335z. This is probably going to be the daytime show. Figure one storm is better than none, so am going to intercept. Not impressed with low level wind fields up there in terms of strength, so not anticipating more than a hailer out of this cell. Looks decent on GRLevel3, though.

Traveling east from Oberlin, trying to get south of this without getting cored -- doesn't look too impressive from here just now, but hopefully it's getting it's act together now that it's split. No hail in Oberlin yet. Nice flying eagle representation on the radar, but this storm doesn't look to be visually rotating at all -- nor does it look that way on radar to me.

The SPC just downgraded to Slight. http://www.spc.noaa.gov/products/outlook/day1otlk.html 100% chance that chasers in southern KS are not happy.

Wall cloud on Kory Hartman's cam at http://www.severestudios.com

Not terribly organized yet.

Tornado Warning issued for the supercell northeast of Colby, which has recently strengthened after a cell merger. Warning was issued for the couplet near Rexford, however a stronger low-level couplet exists near Selden...storm moving into better moisture and instability axis, and with nocturnal increase in the low-level jet...better low-level shear profiles should evolve...appears to be a weak pseudo-warm front southeast of HLC towards HYS...could traverse along the boundary and be fairly long-lived.

Also appears to be a nice BWER between Selden, KS and Leoville, KS.

 

[John Farley]

Nice LEWP with persistent meso moving along U.S. 20 between Fort Dodge and Waterloo in Iowa.

Mark Farnik on the isolated cell coming up on Hill City in Kansas, reports a nice meso between lightning strikes.

 

[Derek Weston]

Farnik believes he sees a tornado about 15 miles east of Hoxie...

 

[Chad Cowan]

The Hill City, KS supercell is going to be very long lived with the onset of the rapidly strengthening LLJ and srly sfc winds advecting the very moist and very unstable air mass northward. I would not be surprised to see this storm maintain its supercellular traits to at least Manhattan (Kansas, that is).

 

[Kenny Drake]

Looks like the Hill City cell will have some time before the cold front undercuts it. If the updraft can maintain the low level downshear pressure perturbations it should stay on it's eastward to southeastward course which will help it stay ahead of the cold front. The supe is right under an area of large-scale ascent (10-25cm/s) so it should be able to maintain it's strength as long as the low-levels don't crap out (ie BL stabilization.)

Power flashes at Hill City reported by chasers Mark Farnik is speaking to.
