Areas affected...west-central Nebraska...northwest Kansas and
extreme northeast Colorado

Concerning...Severe potential...Watch likely=20

Valid 161926Z - 162130Z

Probability of Watch Issuance...80 percent

SUMMARY...Severe storms producing damaging winds and localized hail
appear likely late this afternoon and evening.

DISCUSSION...Strong heating near the surface trough and beneath cool
midlevel temperatures has led to a very unstable air mass for this
time of year over western NE, though overall shear profiles are
weak.

Ongoing storms over northwest NE are likely to extend southward over
the next few hours. Hail may occur with initial development but the
primary risk should be severe winds.

Locally stronger shear does exist in the vicinity of far northeast
CO where surface winds are backed near the boundary and on the nose
of the low-level theta-e plume. A supercell or two may occur in this
region prior to larger-scale mergers/wind threat.
