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

[Andrew Francis]

I concur Steve. Just west and southwest of here in C. OK a decent Cu field is prevalent, I just am not sure anything is going to break through... I am crossing my fingers though! Would be nice to get a cell or two to fire just before dark.

Wondering if a MD will be posted for this area soon.

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.

Sounds landspoutish... I did notice an isolate cell that ran just north of 70 in that area about the time of those reports from Dick. They don't sound supercell cellular.

Heidi:

If there was debris, etc. visible, did either you or Dick phone that info (and the time and location) to Goodland NWS? If not, the number I have is 800-272-7811. I think it would be important to do that.

Looks like these were associated with a small cell well to southeast of a 500 mb cold core over northeast CO. The SPC meso at 21z had pronounced low-level CAPE max in the vicinity of this cell.

Two strong looking Sups in NE Iowa, having trouble rotating due to warm front location. Parkersburg IA probably just got blasted with large hail.

The storm in Smith County, KS at this time has multiple areas of rotation, looking at GR2 .5 degree data from the UEX radar site. Probably very similar in structure to the NW Kansas storm earlier.

 

[Michael Riedl]

Cumulus starting to increase to my south as the storms in Sumner an Cowley start to move in. Visible Satellite confirms. That storm west of I-35 in Sumner County has strengthened Rapidly in the past 30+ minutes. I will probably be intercepting that storm soon.

Does anyone else see some sort of boundary drifting NW towards the dryline on the Norman radar, or am seeing things?

I see it too...looks like a little pre-dryline windshift line. The winds are backed slightly to the east where the boundary layer isn't being entrained by drier air aloft. The winds closer to the dryline are slightly veered as dry air entrainment occurs from aloft. It'll be interesting to see what happens when the enhanced convergence occurs at the intersection of the dryline and this pseudo-boundary.

FWIW, the latest RUC has no precip breaking out over OK tonight. Cu have been struggling the last several agonizing hours (for you OK chasers) west-southwest of the OKC metro.

 

[Andrew Ryan]

The coldfront has entered NW OK. It will overtake the dryline over the next couple of hours. *If* anything will initiate tonight, it will happen then. The cap has been steadily weakening, so this should help. But the high LFCs will make this a challenge. And if anything does go up, it will most likely be elevated due to the T/Td spreads.

I went out after the storms moving to wards Grinnell, Iowa. Almost made it to Grinnell when 3 fire trucks passed me and blocked off the road. Severe tree damage has been reported in Grinnell and the entire town is with out power. There was a possible tornado NE of Grinnell.

Strong storm just north of Cedar Rapids, Iowa still capable of producing a tornado.

 

[Lee C. Bussy]

Had some nickel sized hail, lasted 6+ minutes 2 miles west of Liberty MO @ 17:53 local. Just training storms now.

 

[James Siler]

Looks like the cold front is about to slam into the dry line just west of Wichita, KS. It is visible on the Vance radar. I wonder if anything will pop off were they start intersecting.

Edit: I am limited to what I can view at work. Which is basically radar sites.

 

[Jeremy Jones]

New cells forming in N.central/central OK. I was sitting on US 11 earlier, but called it a day after watching the CU field move into Southern KS. Now I'm at home hoping at least for a decent lightning show in a little bit.

 

[Jeremy Jones]

Just got back in from venturing out to shoot some lightning, at approx. 10:03pm while traveling West on Waterloo Rd. heading home in N. Edmond, I witnessed 2 power flashes, and some downed tree limbs around the Waterloo and Coltrane area. Not quite sure what caused it...pretty sure it was just wind damage. I ended up in a core of pea to marble size hail.

 

[Jason Bolt]

Interesting cell SW of CNU. Seems to be moving slightly ahead of the line, and also looked to make a slight right jog and possess a slight hook a for a couple scans. No real rotation evident but it gives an interesting radar illusion!
