05/21/05: TALK: KS/NE/IA

[Dan Christianson]

ok , MIKE H. headed to norfolk everyone follow ;-)


Outflow.... Thats a game player there, im targeting the Columbus(Sioux City Line but could change in the next few hours all i know is WE better get a show tonight , or something .. NE is due for some tornado'es IN THE FIELD not damaging homes and stuff.... plus we need some friggin RAIN! this dust is killing me"

GL to everyone headed out today...

 

[Justin Walker]

15z RUC is now breaking out precip from SE NE SWard to I-70 at 00z. Central KS beginning to look a little interesting, better moisture and good helicity. But what is killer is the sfc temps, already some upper 90's in central KS. Extremely high LCL's, but I will be watching this area also.

Sitting in Nebraska City at the moment while my partner-of-the-day gets a burger @ Burger King. The DOW Rapid-Scan is parked right next to me. Where's the Flying J with free wifi here that everyone mentioned?

*edit* Aahh, I see. Sapp Bros.

Ryan...

The only free wifi place I see in Nebraska City as provided by the http://www.wififreespot.com/ne.html website is:

Nebraska City
The Long Home Coffee Company - 1121 Central Ave. - 402-873-3777

Here is the location on a mapquest map if you wish to get there...

Hello all at the Sapp Brothers Truck Stop (3 or 4 cars) off of I-29. Holly bugged me about going to the bathroom so I had to get to Wendy's across the street, so that is where I am at right now. Looking good to the north, might head up to Omaha and points north to intercept the outflow boundary before it heads back south.

Ryan the only Flying J- i know of is Near Gretna, right off the I-80 exit, maybe that would help?,


NE Gretna I-80 Exit 432 Flying J

Is anybody else noticing a CU field that is going up across ND, now south through Aberdeen and nearly to the SD/NE border??

[Alex Lamers]

SPC has, they issued an MD for a possible WW for E ND into NW MN. That was one of my two areas of concern for the day. Looks like storms are struggling to develop so far in rather thin higher thetae ridge. Bears watching though. Waiting on 19z mesoanalysis before I get too optimistic...

[Justin Walker]

Cu field going up just west of Norfolk, NE. Looks okay as of now, I do expect this to expand, but struggle with the cap.

 

[tom hanlon]

I am in Lincoln, ran into some other chasers in the parking lot. Will head North ftom here, I like the LCL to the east and the DOW is in Nebraska city but the outflow seems to be as good of a focus area as any.

So although the decision is tough, North to the outflow, east to the LCL and the DOW has chosen east for now.. I am still thinking on heding North.

Good luck to all.

target is basically West Point. If I can find data and need to I may head East into Iowa. Darn river....

Leaving now towards Sioux City(will make further adjustment from there) on I-29, should take 2 hours to get down there. Look for a blue escort w/ SD plates and SDSU & Stormtrack decals. Good luck all!

Sitting by the Best Western, in Nebraska City. Gonna go get a picture of the Armadillo sitting here with all the DOW trucks -- I've always wanted a pic of them lined up together.

 

[Alex Lamers]

Well...several synoptic features have caught my eye. I put them together on this map overlay on satellite imagery:

http://alex.wiscwx.com/mesoanal.PNG

Looks like potential for supercells will be increasing next 2-3 hours over E SD...SW MN...NW IA...NE NE. Plume of enhanced deep moisture influx and thetae ridge coincide appropriately with axis of strongest destabilization. The area is relatively devoid of cloud cover and 19z mesoanalysis indicates that the cap is quickly eroding. Several more discrete boundaries intersect the main front that will likely trigger most of the activity. The first is obviously the outflow boundary from this morning's convection. A wake low over North-Central Iowa has increased wind velocities and backed flow ever so slightly in rain-cooled ams across N IA. Meanwhile, more sse fetch continues near NE/IA border region. The outflow boundary could serve as a later focus for rotating supercells and perhaps tornado spinups. In addition there is a discrete confluence zone evolving across E NE into E KS. It is along this zone that the cu is forming in E NE. Looks like main tornado potential will reside east of this boundary where flow is more backed.

Only one cell on MVX radar so far...so nothing much to watch yet in ND/MN either. Vry cold air aloft plowing into ND with a lot of cu development behind frontal boundaries...so it would be reasonable to see some isolated hail events.

[Scott Olson]

Edward me and Ashley are in Sioux City. Look for a red Jimmy.. We are going to head further south before deciding whether to go anymore west.

Hope to see you by the meso,
Scott.

Sitting at SAPP bros, off of I-29 with about 10-15 storm chasers. Deciding where to go.
