7/10 end of chase
7/10 in-situ update
I am sitting along Hwy 71 halfway between Harrison and Alliance, NE.
The initial storm I intercepted had a nice look to it, however it
croaked. Apparently, the local shear enviornment here favors LEFT
split supercells, instead of the typical RIGHT member. The LEFT mover
is up near Chadron and looks like a beastie on radar! It’s moving
away from me unfortunately. There is, however, another smaller storm
trying to take shape back to my northwest… a little LP thing, which
will probably die as the sun sets here in the next hour. Did get some
images of the first storm, but it is unfortunate it died not too long
after I got close to it. More later.

lets drive back and forth
I left the area I was sitting at near CYS for fears of the Wheatland
and northern Goshen county area going up… and there were very nice
attempts at convective initiation… so I bolted north. Now I am in
Wheatland and these attempts to my north were suckers… well at least
for now. I am watching fairly hard towers, the first attempt already
glaciated up in far northern Goshen county. Now, it would appear,
visually, that the area back to my south…closer to where i was
earlier…is starting to tower fairly hard. I will either head
northeast to Ft. Laramie along hwy 26 from this point…or retrace my
steps back south on I-80. Not sure what to do quite frankly, so I’ll
wait it out for a little bit I guess here in Wheatland.

Small tower NW
early afternoon update 7/10
Currently in Cheyenne as of 12:30pm mountain time… just finished
lunch and plan to head north of town just a bit along I-25, hang out
and watch the sky for awhile. I may end up drifting all the way to
Cheyenne. Very warm 700mb temperatures reside just south of Cheyenne
with the 700mb baroclinic zone from Cheyenne northward. Winds are now
light southeast here in Cheyenne, so the 60s dewpoints will be
creeping west toward me. Anything that forms off the Laramie Range
will not take long to suck in the real good moisture. The RUC has
consistently been generating convective QPF on each of the hourly runs
valid later this afternoon/evening… so there’s hope. More later.

Chase Acct: July 9, 2009 (South-Central NE)
This was a bust. No storms developed in the target area. I actually had two target areas, and even the secondary target area failed to produce a supercell storm… so I’m really not all that disappointed. My primary target was the slowly moving front across Central Nebraska. A couple versions of the NAM and even RUC models hinted at possible convective initiation along the boundary in central Nebraska, and per model soundings, if surface temperatures reached 95 degrees up along this front, there would be a shot. Well, the warmest temperatures I saw on obs as well as per my car’s thermometer, the temperature in the vicinity of maximum convergence along the front never got much above 91 or 92. The mid level temperatures were simply too warm. When the cumulus looked at flat as they did for so late in the afternoon, I knew I was in trouble, and it would take a miracle for something to grow into substantial, hard towers and even further into a storm. The cumulus field did become a little agitated by 5:30 to 6:30pm where I was sitting at southeast of Minden, Nebraska, but it never got beyond that point. At 7:30pm, I called it quits and headed west toward McCook to set up for Day-2. Below is one photo I did take of some high level virga that crossed the area around sunset:

Bustola. Heading to McCook
It’s 7:30, nothing has happened with this cu field, so I am waving the
white flag on this chase day. Heading to McCook for the night.
Hopefully better luck tomorrow on the High Plains!
