NWS STORM PREDICTION CENTER NORMAN OK
0608 PM CDT SAT AUG 29 2026
AREAS AFFECTED...WESTERN INTO CENTRAL NEBRASKA AND SOUTHWESTERN
SOUTH DAKOTA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 292308Z - 300115Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A LINE OF LOOSELY ORGANIZED THUNDERSTORMS HAS PRODUCED
SEVERAL SEVERE GUSTS OVER THE PAST COUPLE OF HOURS. RECENT
RADAR/LIGHTNING TRENDS HAVE SHOWN SOME WEAKENING, THOUGH A FEW
SEVERE GUSTS REMAIN POSSIBLE INTO EARLY EVENING. A WATCH IS NOT
CURRENTLY EXPECTED.
DISCUSSION...A LINE OF THUNDERSTORMS, WITH ONLY ISOLATED DEEPER
CONVECTIVE CORES, HAS CONTINUED TO PRODUCE SEVERE WIND GUSTS IN THE
55-75 MPH RANGE OVER THE PAST COUPLE OF HOURS. AS THIS LINE
CONTINUES EAST THIS EVENING, IT WILL ENCOUNTER A DRIER POCKET OF AIR
WHERE DEWPOINTS HAVE BEEN MIXING OUT LATE THIS AFTERNOON. FARTHER
EAST, IN CENTRAL NEBRASKA/SOUTH DAKOTA, DEWPOINTS ARE IN THE
MID/UPPER 60S F. MRMS CAPPI DATA SUGGESTS THE STRONGEST CORES ARE
LOSING DEFINITION AS THEY ENCOUNTER WEAKER BUOYANCY/GREATER MLCIN.
THOUGH A MODEST INCREASE IN THE LOW-LEVEL JET WILL OCCUR THIS
EVENING, IT IS UNCLEAR IF THESE STORMS WILL MAINTAIN ORGANIZATION
MORE THAN AN HOUR OR TWO GIVEN OTHERWISE POOR SYNOPTIC SUPPORT. A
FEW SEVERE WIND GUSTS ARE POSSIBLE WITH THIS ACTIVITY.
