Synopsis:
Intercepted and photographed two hail storms. The first storm moved east-southeast across Roberts County to the north of Miami and through Canadian before weakening.

A few vivid cloud-to-ground lightning flashes were captured as well.

26 April 2011 Chase Summary & Images -- Northern Texas Panhandle (Part 1)
Summary & Images (part 1)
This was a solo chase while I was on my 10pm to 6am shifts. I knew
this was going to be an early show as far as storm initiation was
concerned, and given the chase target was a little more than two hours
from Dodge City, I decided to make a go of it. Very cool temperatures
aloft and marginal moisture of 45 degree dewpoints would yield about
800 to 1200 J/kg SBCAPE. I targeted the area around Spearman, TX.
The first storm I intercepted was one which formed to my southwest
between Stinnett and Spearman. Unfortunately, this storm was moving
east-northeast through the desolate ranch land of eastern Hutchinson
and Roberts County. I had to drive all the way east to Hwy 70 before
heading south for an intercept. I waited on the storm in northern
Roberts County near the Canadian River. I then followed the storm
southeast along Hwy 283. The sequence of images shown here are of the
storm during this portion of the chase through Roberts County:

Summary & Images (part 2)
*Perryton Storm*

After the first storm dissipated and moved east near Canadian, I decided to
intercept another fairly strong storm that was approaching Perryton from the
Oklahoma Panhandle. This storm was moving east-southeast and would be a
good intercept on the way back home to Dodge City. This was a nice little
surprise and ended up resulting in my best images of this chase. The shelf
cloud associated with this storm was rather photogenic as I approached it
over northeastern Ochiltree County southeast of Perryton. I followed it
south then back to the east along some county roads, stopping every few
miles along the way to photograph.

Summary & Images (part 3)
Cloud to ground lightning east of Perryton


Shortly after photographing the structure of the Perryton storm's shelf
cloud, I continued east on a county road about 8 miles south-southwest of
Booker, where I stopped to photograph some of the fairly vivid
cloud-to-ground lightning. As the storm approached, I booked it east to
Road 1265 where the core of the storm overtook me and I received copious
amounts of pea to penny size hail which covered the road about 6 miles south
of Booker. After this was over, I made my way back to Dodge City.

15z RUC still looks good for northern Texas Panhandle
I left Dodge City shortly after 10am with a target of Gruver-Spearman,
TX in mind. I have seen nothing yet to change this... in fact, the
15z RUC model reinforces this target. A meso-beta scale sweet spot
will likely develop after 2pm across the north-central Texas Panhandle
where near-1000 J/kg CAPE will nose into impressive surface
convergence with cyclogenesis occurring. I should be in Gruver around
1:30pm or so, and I will re-evaluate the situation at that point.

03z RUC showing northeast Texas Panhandle as favorable chase target for tomorrow
Attached below is a graphic of the RUC model valid 21z showing
convection developing in the northeastern Texas Panhandle at the nose
of 800-1200 J/kg SBCAPE. This is from the 03z run of the RUC valid
+18 hours.
