Mesoscale Discussion 1049
NWS Storm Prediction Center Norman OK
0159 PM CDT Tue May 28 2024
Areas affected...portions of south-central TX and the Middle Texas
Coast
Concerning...Severe potential...Watch possible
Valid 281859Z - 282100Z
Probability of Watch Issuance...40 percent
SUMMARY...Thunderstorms may pose a risk for strong gusts and hail
through late afternoon. Trends are being monitored for possible
watch issuance.
DISCUSSION...Isolated thunderstorms are ongoing along an outflow
boundary approaching the Middle Texas Coast vicinity. Visible
satellite shows towering cumulus developing westward along the
boundary across south-central TX. A similar environment to that
across southeast TX where widespread severe is ongoing is present
across this area as well. A hot (mid/upper 90s) and very moist (70s
F dewpoints) boundary-layer is contributing to strong instability
(2000-3500 J/kg MLCAPE). A pocket of steep low-level lapse rates is
also present in latest SPC Mesoanalysis data.
Initial thunderstorm activity has struggled to intensify and it is
unclear if additional storms will develop. If more storms develop
and clustering occurs, damaging wind potential will exist. Trends
will be monitored for possible watch issuance.
