chase update 5/21 215pm

Filed under: chase mode updates — Mike U @ 2:12 pm

Sitting in Torrington Wyoming at 2:15pm CDT. I think I’m in a pretty
darn good area here, mountain convection has already formed in the
Laramies northwest of Cheyenne and southwest of Douglas. I may drift
south and west and find a high spot with digital cell signal and watch
things unfold to my west. Lower 50s dewpoints will be impinging on
extreme southeast Wyoming over the next couple of hours, which should
yield around 1500 to 1800 J/kg CAPE. Deep layer shear profile is just
about as good as you can expect for supercells with 500mb southwest at
around 45 to 50 knots and low level flow increasing from the southeast
at 15 to 20 knots. short-term RUC convective QPF signals make pretty
good sense to me. There should be one or two nice supercells between
Lusk and Pine Bluffs by 00z… or at least that’s the hope.
