ZCZC SPCSWOMCD ALL ACUS11 KWNS 051818 SPC MCD 051818 TXZ000-051915- Mesoscale Discussion 0695 NWS Storm Prediction Center Norman OK 0118 PM CDT Mon May 05 2025 Areas affected...portions of southeastern Texas Concerning...Severe potential...Watch possible Valid 051818Z - 051915Z Probability of Watch Issuance...40 percent SUMMARY...An increase in localized severe potential is evident with an intensifying supercell. Severe wind and hail are the main threats, though a tornado could also occur. DISCUSSION...MRMS mosaic radar imagery depicts a deepening supercell updraft across Lee County, TX, with 40 dBZ echoes exceeding 50 kft and MESH exceeding 1.5 inches. KGRK radar data shows this supercell deviating to the right, toward a surface airmass with mid to upper 70s/60s F temperatures/dewpoints and SBCAPE approaching 1000 J/kg. It is possible that this currently elevated supercell may become surface-based, allowing for this storm to ingest more buoyant parcels and favorable low-level shear (evident via curved low-level hodographs on the EWX and GRK VADs). As such, a severe hail/gust threat may be increasing, and a tornado cannot be ruled out. ..Squitieri/Gleason.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...
