Areas affected...Far southeast Wyoming...far southwest Nebraska
Panhandle...and parts of northeast and central Colorado.

Concerning...Severe potential...Watch unlikely=20

Valid 282120Z - 282245Z

Probability of Watch Issuance...20 percent

SUMMARY...A few strong to severe storms are expected to continue
into the evening.

DISCUSSION...Deep but relatively weak (2km deep and less than 10
knots per FTG VWP) upslope flow has been sufficient for storm
development along the Front Range from southeast Wyoming into
north-central Colorado. These storms have formed on the southern
periphery of stronger mid-level flow and thus a small region of
favorable conditions exists across north-central Colorado into far
southeast Wyoming and vicinity with around 1000 J/kg MLCAPE and
effective shear around 30 knots. Multicell clusters with potentially
some supercell characteristics will continue across the region with
some threat for isolated damaging wind gusts or large hail.=20=20

This threat should wane by late evening as the boundary layer cools
and stabilizes. Due to the marginal intensity and limited duration
of the threat, no watch is expected.
