Mesoscale Discussion 1587
NWS Storm Prediction Center Norman OK
0721 PM CDT Sun Jul 16 2023

Areas affected...Central Nebraska

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

Valid 170021Z - 170145Z

Probability of Watch Issuance...20 percent

SUMMARY...A couple of supercells capable of large hail and strong to
severe wind gusts will continue southeastward into central Nebraska
for a few more hours. No watch is anticipated this evening.

DISCUSSION...A couple of supercells have developed within the Black
Hills and move into parts of central Nebraska. 1 inch hail has been
reported with the southernmost storm. As of 0020Z, both storms
exhibit a three body scatter spike on KLNX radar. Copious amounts of
smoke in the central Plains has stunted surface heating in some
areas. These storms appear to be moving along the weak differential
heating boundary caused by the smoke. Shear is quite strong in the
region, but moisture is somewhat limited. The current expectation is
that these storms will continue for a few more hours southeastward.
Some intensification is possible as they encounter slightly higher
moisture into south-central Nebraska. Large hail (primarily 1-1.5
inches) will be possible along with isolated strong to severe wind
gusts.
