Areas affected...Portions of east-central Colorado...far southeast Wyoming...and the Nebraska Panhandle

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

Valid 132042Z - 132245Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated strong to severe thunderstorms capable of
producing severe hail and locally damaging gusts are possible this
afternoon. The severe threat should eventually increase farther east
into this evening.

DISCUSSION...Isolated/discrete thunderstorms are evolving
along/immediately east of the Colorado Rockies and northward into
the Nebraska Panhandle this afternoon, as diurnal heating continues
to erode MLCINH along a surface wind shift/lee trough. Over the next
couple hours, a few of these storms may intensify and pose a risk of
isolated severe hail and locally damaging gusts -- aided by around
30 kt of 0-6 km shear (sampled by DEN VWP and latest ACARS
soundings). Overall, weak instability and limited large-scale
forcing should limit the severe threat with these initial
thunderstorms. With time, thunderstorms should increase in coverage
and spread eastward into richer boundary-layer moisture and
associated instability -- which should favor an increasing severe
risk into this evening. A watch is not expected for the initial
thunderstorms developing along/immediately east of the higher
terrain in the near-term, though convective trends will be
monitored.
