NWS STORM PREDICTION CENTER NORMAN OK
0112 PM CDT SUN AUG 23 2026
AREAS AFFECTED...PORTIONS OF THE CENTRAL GULF COAST
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 231812Z - 232015Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...WIDELY SCATTERED THUNDERSTORMS MAY POSE A RISK FOR
ISOLATED DAMAGING WIND GUSTS THROUGH THIS AFTERNOON AND EVENING.
WATCH ISSUANCE IS NOT ANTICIPATED.
DISCUSSION...LATEST OBJECTIVE ANALYSIS INDICATES MLCAPE HAS
INCREASED TO 2000-3500 J/KG ACROSS PORTIONS OF THE CENTRAL GULF
COAST/LOWER MISSISSIPPI RIVER VALLEY AMID A HOT/HUMID LOW-LEVEL AIR
MASS, WHICH IS ALSO SUPPORTED BY A MODIFIED 12 UTC SOUNDING FROM
LIX. WHILE LOW-LEVEL FLOW REMAINS RELATIVELY WEAK (LESS THAN 20 KTS
SAMPLED BELOW 4 KM AGL BY REGIONAL VWPS), PW AROUND 1.75 INCHES AND
STEEPENING LOW-LEVEL LAPSE RATES AMID MODERATE TO STRONG BUOYANCY
SHOULD SUPPORT A RISK FOR ISOLATED DAMAGING WIND GUSTS WITH ANY
STRONGER MICROBURSTS. THE GREATEST POTENTIAL MAY EXIST/DEVELOP
ACROSS PORTIONS OF SOUTH-CENTRAL LOUISIANA WHERE CURRENT
OBSERVATIONS/GUIDANCE SUGGEST A LOCALLY MORE FAVORABLE THERMODYNAMIC
ENVIRONMENT FOR DOWNBURSTS MAY EXIST (AS SUPPORTED BY MICROBURST
COMPOSITE PARAMETER VALUES OF 7-8 PER LATEST MESOANALYSIS). THE
OVERALL RISK IS FORECAST TO REMAIN ISOLATED IN NATURE AND LIMITED IN
MAGNITUDE, HOWEVER, WHICH SHOULD PRECLUDE THE NEED FOR A WATCH.
