MD 1165 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTH-CENTRAL NEBRASKA

Mesoscale Discussion 1165
NWS Storm Prediction Center Norman OK
0109 AM CDT Fri Jul 10 2020

Areas affected...South-central Nebraska

Concerning...Severe potential...Watch unlikely 

Valid 100609Z - 100845Z

Probability of Watch Issuance...20 percent

SUMMARY...An isolated wind damage threat will likely continue for 1
to 2 hours across south-central Nebraska. The threat is expected to
remain too localized and short-lived for weather watch issuance.

DISCUSSION...A small cluster of strong to severe is evident on radar
imagery to the east of North Platte, Nebraska. The strongest cell in
this cluster generated a wind gust of 76 kt over the last hour. The
cluster is located near the eastern edge of moderate instability as
is analyzed by the RAP. For this reason, the cluster may turn more
southeastward and move more closely parallel to the instability
gradient. The North Platte WSR-88D VWP is sampling the rear inflow
jet with this feature showing 50 kt of west-northwest flow near 4 to
5 km above ground level. This may enable to cluster to continue to
produce damaging wind gusts for awhile longer. However, as the
storms interact with weakening instability, the threat should remain
isolated and appears likely to decrease. Weather watch issuance is
not expected.
