5/21/2010 - Wyoming-Nebraska Supercells/Funnels

24 hrs and 1150 miles later I find myself in Alliance, NE. For Friday, I initially targeted the area along the WY/CO border -- I-80 to I-76 corridor -- but upon arriving in the target area, decided to scoot north. Fell behind a supercell east of I-25 in southeast Wyoming (no good road northeast), but did view several funnels and some nice structure once I caught up to it. Fought a nasty road network as the supercell moved northeast into a remote area along the WY-NE border. Caught back up to it well north of Scottsbluff, where I watched the wall cloud off in the distance. I let that storm go -- heck, there were no roads and it showed signs of dissipating -- and turned my eye to the west where another supercell got going at sundown. Despite the really, really cold surface air, it had the appearance that it may drop a tornado north of Agate Monument, but, alas, it never did. Always fun to see supercells in the Sandhills ... now, if they would just build some more damn roads out here! Ted Turner .. you hear that?!

Storm moving over the Laramie Range ... and moving into the High Plains.

Supercell ... oh, please, slow down, so I can catch you!

Had initial hope this trailing storm over the mountains would mature ... but, it never did.

Wall cloud with intermittent funnels.

Nice clear slot ... thing seemed to funnel quite a bit, but never dropped anything substantial.

Now in Nebraska ... this is the storm V2 sampled. Actually, same storm as above, just starting to dissipate. Yeah, a nice lowering ... but the surface temp was really cold here!

I was looking for my stocking cap at this time ... it was that cold!
