4/6/10 NOW: KS, MO, IA, OK

[Mike Johnston]

Convective initiation...just east of Newton, KS, cell has gone up rather rapidly. SPC just issued SVR watch for eastern KS and northwest MO. Previous mesoscale discussion had indicated a TOR watch was likely over this area, but they evidently backed off on that for now.

They may be right about sfc-850 veering; however, Neodesha KS to Haskell OK profiler data showing very slgt improvement last two hours, likely courtesy of the approaching jet seg from NM. Moisture is yet again a concern. Mixing is pushing dews toward the low 60s in both target zones. Despite these limitations, a particularly robust and isolated supercell could spin up a small torn. I'm sitting this one out, but good luck to those chasing.

Kansas/Oklahoma

DL/CF intersection near Wichita with new storm.

DL may go all the way down to I-40 in OKLA WATCH OUT!!

 

[Jeremy Den Hartog]

Currently about 30 miles east/south east of Des Moines, IA. Very muggy - just waiting to see a tower to go up and head in that direction...

 

[Aaron Locke]

I am stuck at work on the west side of ICT and watched the cell north of town go up in a matter of 10 minutes. Looks rather high based from where I am sitting but looks good on radar.

Today's setup has some similarities to April 19, 2000. The biggest difference (southern target) is the dewpoints are 4-6 degrees lower today.

That's not too surprising given the high LCL heights invof that developing line. SPC mesoanalysis shows >1500m AGL (based off a mixed layer parcel ascent -- which also still shows some CINH lingering) thanks to the >20-25f T/Td spreads across eastern KS. I'd have to doubt any convection further down the dryline would be capable of producing a tornado -- especially due to the south/southwesterly sfc flow, which in turn leads to the meager low-level SRH.

MD just issued by SPC for West-Central OK. CU field near dryline is beginning to look more "agitated" and surface heating is weakening cap. Just a few degrees warmer and in another hour or so initiation should occur along the dryline down into Northern-Cntrl OK. Surface winds have remained southerly which looks good for rotating sups.

Osage County, KS 21Z

Osage County, Kansas storm bears watching as I write at 21Z (4pm Local). It is south end of a line (north side of the break in the line) and vectoring slightly right of others. Slight rotation shown on storm relative. Could be an easy follow on I-35 but always put safety first on a busy Interstate.

OKLA NOW

Winds are backing a head of DL in Central Oklahoma exspect watch soon. TCU are growing along DL fom ICT to CSM.

UPDATE: New Storm on DL KS/OK Border TCU now breaking the cap from ICT-END area.

Dick McGowan has had multiple tornadoes in western Kansas along I-70 in the past couple of minutes, near Grinnell. He reports damage/debris in the air, just a few miles north of the interstate.

Edit: Dick was in fact just east of Wakeeney at the time of the tornadoes, not Grinnell.

 

[Michael Riedl]

Just got back from driving up to Northern Butler. Not too much going on . Lots of lightning and some heavy rain and some hail. It looks as if something might be getting going in Sumner county KS. Going to go wait and hope it continues to build and Intercept in Southern Butler county.

 

[Steve Miller]

In El Reno, OK looking to my SW at a solid CU getting started. Quick look at salellite confirms. Maybe we can get something to go in the next little while.

I am looking for any reports on this and cannot find anything. Can you elaborate?

 

[MatthewCarman]

NWS never had a tornado warning for that storm in western Kansas. Did anyone see rotation with that storm on radar? I checked BV1 and SV1 and never saw any but maybe I was not looking right.
