NWS STORM PREDICTION CENTER NORMAN OK
1212 PM CDT SUN JUL 12 2026
AREAS AFFECTED...NORTHEAST TX VICINITY INTO NORTHERN LA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 121712Z - 121915Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED THROUGH
THE AFTERNOON. SPORADIC STRONG GUSTS ARE POSSIBLE, THOUGH SEVERE
POTENTIAL IS EXPECTED TO REMAIN LIMITED.
DISCUSSION...A VERY MOIST AIRMASS CHARACTERIZED BY 70S F DEWPOINTS
IS IN PLACE ACROSS THE ARKLATEX VICINITY THIS AFTERNOON. STRONG
HEATING OF THIS VERY MOIST AIRMASS ALONG A WEST TO EAST ORIENTED
SURFACE BOUNDARY IS SUPPORTING MODERATE INSTABILITY AS OF MIDDAY.
THUNDERSTORMS ARE ALREADY DEVELOPING ALONG THIS BOUNDARY, AND ON THE
SOUTHERN PERIPHERY OF A CONVECTIVELY ENHANCED VORTICITY MAXIMA.
VERTICAL SHEAR WILL REMAIN WEAK TODAY, LIMITING A MORE ORGANIZED
SEVERE RISK. HOWEVER, STEEPENING LOW-LEVEL LAPSE RATES THROUGH THE
AFTERNOON IN CONJUNCTION WITH WATER LADEN DOWNDRAFTS, COULD SUPPORT
SPORADIC WET MICROBURSTS, WITH A FEW STRONGER GUSTS POSSIBLE. A
SEVERE THUNDERSTORM WATCH APPEARS UNLIKELY AT THIS TIME.
