Areas affected...parts of southeastern Wyoming and adjacent
northeastern Colorado/southwestern Nebraska

Concerning...Severe potential...Watch possible=20

Valid 081951Z - 082145Z

Probability of Watch Issuance...60 percent

SUMMARY...Renewed isolated supercell development possible through
late afternoon. Trends are being monitored for the possibility of a
severe weather watch.

DISCUSSION...Isolated vigorous thunderstorm development is already
underway near/north of the Cheyenne Ridge, likely supported by
inflow emanating from a narrow corridor of low-level moistening
along the Front Range into southeastern Wyoming. Although warming
mid-levels and slower low-level moisture to the east of the higher
terrain may initially inhibit eastward propagation of stronger
convection, upslope flow into the higher terrain near/east of
Cheyenne may provide a focus for renewed strong to severe
thunderstorm development through late afternoon. Beneath modest,
but strongly sheared, southwesterly deep-layer mean flow, this may
include an evolving supercell or two accompanied by the risk for
large hail.
