Mesoscale Discussion 1106
NWS Storm Prediction Center Norman OK
1050 AM CDT Sat Jun 01 2024
Areas affected...Middle/upper TX coast vicinity
Concerning...Severe potential...Watch possible
Valid 011550Z - 011745Z
Probability of Watch Issuance...60 percent
SUMMARY...Some severe threat could continue and possibly increase in
coverage this afternoon, with a threat of damaging wind, hail, and
possibly a tornado.
DISCUSSION...A strong thunderstorm cluster that earlier evolved near
Port O'Connor is moving offshore late this morning. Some convection
is spreading northeastward out of this cluster (possibly aided by
outflow), while a couple of small supercells are ongoing near the
coast across Matagorda/Brazoria Counties. Some deepening cumulus is
also noted closer to Galveston Bay, within an increasingly uncapped
environment.
Storm evolution into the afternoon remains uncertain across the
area, but based on current trends, some increase in storm coverage
and intensity appears plausible with time and northeastward extent
toward the upper TX coast. Some redevelopment will also be possible
farther south, along the trailing outflow from the ongoing storm
cluster.
Very rich low-level moisture, strong to locally extreme buoyancy,
and sufficient deep-layer shear will continue to support potential
for organized convection, including a couple supercells and/or
stronger clusters with an attendant risk of isolated damaging wind,
hail, and possibly a tornado (though low-level flow/shear is
expected to remain rather weak). Watch issuance is possible if
larger corridor of severe potential becomes evident.
