Areas affected...Eastern Colorado...Northwest Kansas...Southwest and
Central Nebraska

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

Valid 292155Z - 300030Z

Probability of Watch Issuance...20 percent

SUMMARY...An isolated severe threat will continue across parts of
the central High Plains through early this evening. Severe gusts and
hail will be the primary threats. The potential should remain
marginal, and watch issuance is not expected.

DISCUSSION...Latest water vapor imagery shows a plume of mid-level
moisture from the southern Rockies into the central High Plains.
Scattered thunderstorms are ongoing within this plume, from a
surface low in southeast Colorado northeastward along and to the
west of an inverted surface trough. Moderate to strong instability
is analyzed by the RAP along much of this trough, but deep-layer
shear is weak. This is evident on the Goodland and North Platte
WSR-88D VWPs. In spite of the weak deep-layer shear, low-level lapse
rates are very steep, which should support an isolated wind-damage
and hail threat.
