Areas affected...Southern Nebraska

Concerning...Severe potential...Watch unlikely 

Valid 250419Z - 250645Z

Probability of Watch Issuance...20 percent

SUMMARY...A wind-damage and hail threat may continue for a few more
hours across southern Nebraska. The threat should beco*e more
isolated and marginal with time, and weather watch issuance is not
expected.

DISCUSSION...The latest high-resolution radar from Hastings shows a
short bowing line segment about 40 statute miles to the east of
McCook. This line is located along an east-to-west axis of strong
instability, where the RAP is analyzing MLCAPE in the 3500 to 4000
J/kg range. In addition, the latest WSR-88D VWP from Hastings has
0-6 km shear in the 30 to 35 knot range, along with strong
directional shear in the lowest two kilometers. This should be
favorable to continue an isolated severe threat for another hour or
two. However, a cap is exists further to the east along the
instability axis. As the short line segment moves into this capped
airmass, a weakening trend is expected to develop.
