Mesoscale Discussion 1753
NWS Storm Prediction Center Norman OK
1254 PM CDT Wed Aug 31 2022

Areas affected...much of central Nebraska

Concerning...Severe potential...Watch unlikely 

Valid 311754Z - 312030Z

Probability of Watch Issuance...20 percent

SUMMARY...A few severe gusts are possible with the stronger storms.
The severe threat is expected to remain relatively isolated through
the afternoon.

DISCUSSION...MRMS mosaic radar imagery depicts an increase in
convective coverage and intensity across northwest NE as a small
mid-level impulse grazes the central Plains. Ahead of the storms,
strong diurnal heating is contributing to surface temperatures
exceeding 90 F, with a dry boundary layer growing to 600 mb and
low-level lapse rates steepening past 9 C/km. As such, continued
intensification of the ongoing storms amid the warm/dry low-level
environment should promote enough evaporative cooling to support
strong wind gusts, and a few gusts exceeding 50 kts are possible.
Nonetheless, shear and upper support are expected to remain weak, so
storm organization should remain fairly limited, with any severe
gusts being isolated.
