MD 2124 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR PORTIONS OF CENTRAL INTO SOUTHERN TEXAS
Mesoscale Discussion 2124
NWS Storm Prediction Center Norman OK
0459 PM CDT Sat Sep 09 2023
Areas affected…portions of central into southern Texas
Concerning…Severe potential…Watch unlikely
Valid 092159Z – 092330Z
Probability of Watch Issuance…20 percent
SUMMARY…A few instances of severe wind and hail may accompany the
stronger storms. The severe threat should remain isolated and a WW
issuance is not expected.
DISCUSSION…Pulse cellular and multicellular storms have been
increasing in intensity and coverage across central TX toward the
middle TX coast over the past couple of hours. Despite weak vertical
shear, these storms continue to intensify atop a hot, well-mixed
boundary layer, with surface temperatures well exceeding 100 F,
boosting MLCAPE to 1500+ J/kg. Water-loaded downdrafts within the
stronger storm cores may support a couple of severe gusts along with
an instance or two of hail. Nonetheless, the lack of more
appreciable vertical shear should render the severe threat brief and
isolated, precluding a Severe Thunderstorm Watch issuance.
