MD 1336 CONCERNING SEVERE POTENTIAL…WATCH LIKELY FOR LOWER/MIDDLE TEXAS COAST AND DEEP SOUTH TEXAS
Mesoscale Discussion 1336
NWS Storm Prediction Center Norman OK
0657 PM CDT Wed Jun 19 2024
Areas affected…Lower/middle Texas Coast and deep south Texas
Concerning…Severe potential…Watch likely
Valid 192357Z – 200100Z
Probability of Watch Issuance…80 percent
SUMMARY…Tornado risk to increase through the evening as outer
bands of Tropical Storm Alberto move inland across the lower/middle
Texas Coast.
DISCUSSION…Recent radar imagery has shown supercells developing in
a band of convection just off the middle Texas Coast northeast
Corpus Christi. At least transient rotation and supercell structures
are expected to increase as low-level shear strengthens through the
evening. Forecast soundings show greater low-level shear and
curvature in hodographs after 00z across much of the area across
south Texas and inland to the Rio Grande Valley. This will lead to
an increase in embedded supercells within bands of deeper convection
and potential risk for tornadoes. Isolated supercells also may
develop over the Gulf and move ashore south of the primary band(s).
A watch is likely to be needed in the next hour.
