Chase Case #9

[Marc Austin]

After having a nice lunch with Dann and Patrick in North Platte, and after seeing the 15z data, I moseyed on down 1-80 to Grand Island, NE. Now having seen the 18z data, I've spotted an area of agitated cu developing to my east in the vicinity of York, NE, so I am heading there and am going to go find Marc and harass him .
I'm really liking the tongue of upper 60's dews that have nosed into south central/southeastern NE and the resultant low t/d spreads, which will create favorable LCL's for tornadic activity. Also digging the backing winds occurring from GRI north and east.
I will hold down the fort in York for the time being and monitor this cu field for initiation, but am also keeping a wary eye to the west/north and am prepared to blast north on Highway 81 to Columbus.

You can harass me all you want as long as we bag a tube today ! I've got a pretty good feeling about this location (York, NE). Ample moisture, good backing of winds... now we just need a little lift to spark a nice structured supercell. If anything starts going up further north, Columbus is only an hours drive. Still have the opportunity to chase in KS as well if things get going down there. Now it's a waiting game, which I'm really bad at in real life, so I'm glad this is virtual!

Im leaving my original target of Grand Island, NE and heading up towards Yankton, SD, although I will probably stop in NORFOLK, NE for further updates. I should be able to get east in to Iowa should things go up there, otherwise it looks like we may have a boundary here in northeast Nebraska. I cant stand those southwest winds in southern Nebraska anymore.

 

[Corey Sloan]

Sitting tight in the Hamburg, IA area....road structure is ok to go any direction...waiting on data.

 

[Andrea Griffa]

I mantain my target Taylor,Ne and looking the satellite I've noticed that Southern Ne is starting to clear out. I'm ready to go east toward the IA border.

 

[Michael O'Keeffe]

Going to stay in O'Neill, NE. I may drift east a little and take a look at the developing cu to my east and south.

 

[Randall Cooper]

I'll move east toward Kearney, NE

 

[Jeff Duda]

I've been sitting near Danville, IL (near the IL/IN border on I-74) since the initial time. I'm waiting for that boundary swinging out of the NE to light up with good moisture and sfc heating. Upper level jet streak is moving away far to my NE, but associated upper level divergence may aid in initiating storms.

 

[Greg McLaughlin]

I'm still flying east on I-80. I am on the west side of Des Moines, IA and will continue east to Newton. It is 2pm and Newton is 46 miles away. I am making great time and will continue to get east as quickly as I can.

1930 UTC Supplemental

Just a quick supplemental before the 21z update is posted a little later tonight:

So, if you're sitting out in NE or KS wondering if the cap will hold, do you bite on the MD and bolt for IA? Maybe the second MD signals cool air aloft moving in from W NE. Want some battle scars for your chase mobile? Or do you just wait for the full 21z update to decide? Maybe you're waiting in IL and wondering about timing. It's an hour and a half of available travel time, so what's it gonna be? Good luck with your choices. 21z will be posted a little later tonight.

Leaving Peru Illinois, heading to Cedar Rapids, IA

 

[Joe Karel]

Ill head from Des Moines IA to Waterloo to get into that MD area. That'll still give me road options in every direction it looks like so that'll be my target: Waterloo, IA

 

[Corey Sloan]

Going from Hamburg, IA to Ames, IA...will check data there...not wanting to bite on the MD but think I should be further north and east

 

[Greg McLaughlin]

I'm going to take 330 up to Marsalltown, IA and then figure out where to go from there. I think I will be in pretty good position within an hour or so. I hope convection holds off long enough for me to get where I need to be.

 

[Matt Gingery]

Alot of action along the warm front up in Iowa area. May begin to start getting act together out along the front range from E. Wyoming into E. Colorado. We are in Wichita hedging our bets for better chasing tomorrow. At this point we are discussing heading to Garden City Kansas to set up for tomorrow. We should be will be in Greensburg Ks. by the next update if we leave now.

*Reads 15Z update.*
Things that make you go, hmm… I’m noticing the moisture advection taking place over parts of Nebraska. Really would have liked to have traveled to parts of Iowa where the outflow boundary will have the opportunity to tap into some deep moisture and more impressive veering of the winds over that region. Nonetheless, the winds are backed over parts of Nebraska and noticed the skies are clearing. I’m hoping that the cap will break later on in the day and anxious to see the WV for the next update. Going to go ahead and nudge just a little east from Grand Island to York, NE.

*Reads 18Z update.*
Noticed the moderate moisture axis over south-central Nebraska progressing northward on the visible and pressure falls over the eastern region of the state. Going to go ahead and move northward on 81 from York to Columbus, NE. I almost want to travel further northeast of Columbus but will wait until the next update and go from there...
