Chase Case #9

[Brian Stertz]

Keeping a watchful eye on this cell blossoming just sw of Cedar Rapids. This one has that look and is on the southernmost inflow side of the larger complex of storms..which is where big daddy supercells love to thrive and bear nasty fruit.

We are still hanging in Greensburg. We are positioned to move towards Dodge City, Liberal, or even head NW towards Goodland Ks. if needed. At this point we are in position for a two stage event. Looks like the dryline surge to our NW will hopefully initiate some action before sundown and give us some cells to chase. I feel confident that the day will produce something big. I am confident that the cap will give out soon. Am I the only one chasing in SW Kansas? If so, does that mean that if I get some video it will be exclusive? I hope so! Good luck everyone else. . .

With only a couple hours of daylight left, pick your storm(s) and make any final position adjustments. The results will be posted late, late tonight. How do you think you did?

Chaser Positioning Map

 

[Derek Weston]

Being that I'm from Cedar Rapids/Iowa City... I'd have sat right there and waited for the nice big sup that traversed the area.

Think I know what day this is, so never posted.

 

[Randall Cooper]

I'm heading home, looks like i busted. Maybe I can see some distant lightning on my way home.

 

[Jason Branz]

Well, let's drop south through York on 81 and play with the stuff over near Grand Island. I'd drop farther south and play with the NC Kansas cell, but we'll take the first one in line and go from there. The T/Td spreads down in KS are a little high for my liking, although right along the border they're not too bad.

 

[Jim Tang]

Meh, I'm in the middle of all the action but gosh that grungy, undercut stuff in IA doesn't attract me. I guess I'll stay or maybe move a tad south into NE NE.

 

[Michael O'Keeffe]

Intercepting the developing cells SW of Norfolk, NE.

I will stick with the supercell that continues to ride the surface warm front along / near I-80. I would have to bet it's produced tornadoes -- if not a long-track one based on the low-level shear / thermodynamic profiles within the inflow sector.

 

[Brian Stertz]

I am continuing to stick with the supercell that rolled out of E. Iowa into NW Illinois. I am with Nick on this one. It had to have produced some tornadoes back in Iowa before it eventually became a little more outflow dominated. Still it is the play I had hoped for and I need to stick with it.

 

[Joe Karel]

I'm sitting at the intersection of 35 and 20 in north central Iowa and since its getting dark I'm headed to the closest cell which would be to the north and slightly west. I'll head north on 69 into wright county and see what happens..

 

[Bob Hartig]

Well, I'll be an unkey's muncle...it looks like there will be joy in Muddville after all, or at least a chance of tornadoes in Nebraska. Suddenly I'm feeling really pleased that I booted east to Platte Center. That little blip just northeast of my previous position in Greeley looks like the beginnings of something. So does that stronger blip to its NNE. I know I can catch the southernmost cell, and I'm pretty sure that its northern neighbor is also within my reach. Think I'll start scoonching north on US 81 for an intercept while these guys hit puberty and build some muscle.

Keeping my eyes to the west, too, where the dryline is advancing. This next hour ought to be interesting. I hope so, anyway.

 

[Marc Austin]

After arriving in Omaha, NE. I would have most likely been tempted by the storm in IA, but realizing how fast it was moving, stayed put until the 21Z update. After the 21Z update, I would have been depressed, but possibly would have waited a while longer or moved toward Norfolk, NE or possibly back down toward my initial target of York, NE. Although I don't expect tornadoes, I would hope for a glimpse of structure and possibly a nice lightning show.

 

[John Farley]

Just having looked at the 0Z data, I am moving north from Peru to intercept the storms now firing north of there near Rochelle, IL. If these storms can become surface based and if they intensify rapidly as I anticipate, the potential for seeing a tornado will be good.
