High Plains Drifter

I am currently located along Lake Oahe west of Gettysburg, SD. A
dangerous convective situation is about to unfold around this area.
SPC mesoanalysis shows 5000 J/kg of surface based CAPE and a couple
hundred joules of 0-1km SRH which computes to an EHI of over 7.
Strong tornadoes are very possible, if not likely, in this environment
if a surface based storm forms in this area… which pretty much all
the models suggest happening. The area along the SD-ND border east of
Mobridge appears especially vulnerable during the evening hours. I
will stay on the east side of the Lake and watch things bubble to my
west… as it appears to be doing as I type. It could be a long
evening.
