Mesoscale Discussion 0273
NWS Storm Prediction Center Norman OK
1046 AM CDT Fri Mar 28 2025

Areas affected...Parts of east TX and western LA

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

Valid 281546Z - 281745Z

Probability of Watch Issuance...20 percent

SUMMARY...Strong to locally severe storms are possible into this
afternoon, with a threat of locally damaging gusts and possibly a
tornado.

DISCUSSION...Several northward moving cells/clusters are ongoing
across east TX late this morning, to the east of a convectively
enhanced midlevel shortwave trough moving slowly eastward across
south TX. Area VWPs depict rather strong southerly low-level flow,
with some low-level hodograph curvature implied where surface winds
remain backed out of the southeast. MLCAPE may gradually increase
near/above 500 J/kg into late morning and this afternoon, with
continued storm development possible within the moist and uncapped
environment.=20

While deep-layer shear will remain relatively modest, effective SRH
of 100-200 m2/s2 will support occasional storm organization. Given
the relatively favorable low-level shear/SRH and rich boundary-layer
moisture, a tornado cannot be ruled out with any sustained cells,
while locally damaging gusts will be possible with any stronger
cells/clusters.=20

Watch issuance is unlikely in the short term due to the isolated
nature of the threat, but trends will be monitored for the potential
of stronger diurnal heating/destabilization and a locally greater
threat into the afternoon.
