NWS STORM PREDICTION CENTER NORMAN OK
1242 PM CDT TUE JUL 07 2026
AREAS AFFECTED...EASTERN TEXAS INTO CENTRAL LOUISIANA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 071742Z - 071915Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A FEW STRONG TO SEVERE GUSTS MAY OCCUR THIS AFTERNOON. THE
SEVERE THREAT SHOULD REMAIN ISOLATED OVERALL, SO A WW ISSUANCE IS
NOT CURRENTLY ANTICIPATED.
DISCUSSION...MRMS MOSAIC RADAR AND NLDN LIGHTNING DATA BOTH SHOW A
RE-INTENSIFICATION OF A THUNDERSTORM CLUSTER, WHICH IS GRADUALLY
ORGANIZING INTO A SOUTHWARD-SAGGING MCS STRUCTURE. THE SOUTHWEST
FLANK OF THIS MCS IS BEGINNING TO INTERACT WITH A RELATIVELY
PRISTINE AIRMASS PRECEDING A STALLED OUTFLOW BOUNDARY REMNANT FROM
EARLIER CONVECTION. HERE, SURFACE TEMPERATURES ARE EXCEEDING 90 F
AMID LOW 70S F DEWPOINTS, YIELDING OVER 2500 J/KG MLCAPE. WHILE
DEEP-LAYER SHEAR IS WEAK, THE AFOREMENTIONED BUOYANCY SHOULD SUPPORT
WET DOWNBURSTS CAPABLE OF DAMAGING GUSTS, ESPECIALLY WITH COLD POOL
MERGERS ALONG THE LEADING LINE. GIVEN POOR VERTICAL WIND SHEAR, THE
SEVERE THREAT SHOULD BE ISOLATED, WITH A WW ISSUANCE NOT CURRENTLY
EXPECTED.
