About This Shoot
Date: 16 June 2013
Location: Southwest Nebraska to Northwest Kansas from Ogallala, NE to Atwood, KS
Shoot Type: Storm Chase
The keynote sequence of this chase was around and southeast of the Atwood area when a menacing HP supercell formed just south of the NE-KS state line. I followed this storm southeast on a county road grid stopping as often as possible ahead of the storm to take structure shots. It was a very impressive storm which quickly became outflow-dominant. Before this storm, I chased a supercell earlier on with Jay Antle (he broke off the chase at Trenton, NE) which also had some decent structure at times across far southwestern Nebraska.

Atwood, KS HP Supercell

Mon, 17 Jun 2013 20:55:02 -0500
High-based supercell undergoing development with wicked scud cloud formation to the west
Atwood, KS HP Supercell Summary & Images (part 1)
This sequence of images was from 3:42pm to 3:57pm CDT looking west from a location about 9 miles south of Highway 23 and 7 miles west of Highway 25 southeast of Grant, Nebraska (40.6985016,-101.2869034). Jay and I found this nice overlook at a county road intersection watching the outflow scud forming at ground level and lifting up into the strong updraft of the developing supercell storm.

Supercell storm moving south-southeast wrapping some rain curtains in high-based circulation
Atwood, KS HP Supercell Summary & Images (part 2)
A little bit further south than the previous shooting location (40.6283913,-101.2885971), Jay and I observed the storm wrap some rain curtains in a developing rear-flank downdraft region of the storm. A few attempts at funnel cloud wannabes were observed. Cloud-to-ground lightning was frequent enough in the forward flank downdraft/downshear anvil region of the storm to attempt at some Lightning-trigger shots, with one good frame and one better CG that barely caught the right edge of a frame in another shot.

Storm taking on more of a linear appearance and less supercellular near Imperial, NE
Atwood, KS HP Supercell Summary & Images (part 3)
This particular stopping location was halfway between Hwy 61 and 25, due east of Imperial, NE (40.5318909,-101.2875977) looking almost due west.  Dual precipitation cores were noted, which provided for some interesting shots.. including a rainfoot on the northern rain shaft.

High-based structure shots as we continue south through western Hayes County, NE
Atwood, KS HP Supercell Summary & Images (part 4)
Time around 4:45pm CDT as we stopped briefly for structure shots looking to the west. The storm was taking on more precipitation in the rear-flank. A tall precipitation shaft was also rather cool to see to the northeast of the aforementioned rear-flank precip. Location west of Hayes Center (40.5107002,-101.2119980)

Storm structure and lightning with scenic foreground just north of Hamlet, NE
Atwood, KS HP Supercell Summary & Images (part 5)
The storm continued to exhibit non-supercell characteristics as it rolled south-southeast at 5:00pm. We found this nice scenic view on Hamlet Road just north of Hamlet, NE (40.411666, -101.223078) as we continued south on county dirt roads. I managed to capture one cloud-to-ground flash, which I cropped to a panoramic 3:1 image as shown here in Image #3
