Areas affected...Southern...Central and Eastern Nebraska

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

Valid 310012Z - 310215Z

Probability of Watch Issuance...20 percent

SUMMARY...An isolated hail threat will likely develop this evening
as cells increase in coverage across southern and eastern Nebraska.
This activity will remain mostly elevated, and weather watch
issuance appears unlikely.

DISCUSSION...Over the last hour, isolated thunderstorms have
initiated over southern Nebraska, about 60 statute miles to the
east-southeast of North Platte. According to surface analysis, this
convection is located just to the northwest of a quasi-stationary
front. The convection is also located to the north-northeast of a
center of instability, where the RAP has MUCAPE estimated near 1000
J/kg. The WSR-88D VWP at Hastings shows substantial speed shear in
the lower to mid-levels, which is contributing to deep-layer shear
near 60 knots. This, combined with 700-500 mb lapse rates of 7.5 to
8.0 C/km, will be favorable for hail. This will especially occur as
convective coverage and warm advection increase later this evening.
The cells should remain elevated, on the cool side of the front,
with any severe threat being marginal.
