NWS STORM PREDICTION CENTER NORMAN OK
0127 PM CDT FRI JUL 11 2025
AREAS AFFECTED...PARTS OF MN INTO EASTERN SD
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 111827Z - 112030Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...STRONG TO LOCALLY SEVERE STORMS ARE POSSIBLE THIS
AFTERNOON.
DISCUSSION...STORMS ARE GRADUALLY INCREASING IN COVERAGE EARLY THIS
AFTERNOON ACROSS WEST-CENTRAL MN, IN THE VICINITY OF A COLD FRONT.
ADDITIONAL BUILDING CUMULUS AND INITIAL STORM DEVELOPMENT HAS
RECENTLY BEEN NOTED ALONG/AHEAD OF THE FRONT ACROSS NORTH-CENTRAL
MN. ADDITIONAL STORM DEVELOPMENT WILL BE POSSIBLE ALONG/AHEAD OF THE
FRONT THIS AFTERNOON AS A MID/UPPER-LEVEL SHORTWAVE TROUGH MOVES
ACROSS SOUTHERN SK/MB AND ND AND APPROACHES THE REGION FROM THE
WEST.
THE STRONGEST MID/UPPER-LEVEL FLOW ASSOCIATED WITH THE APPROACHING
SHORTWAVE WILL LAG BEHIND THE FRONT, RESULTING IN RELATIVELY WEAK
DEEP-LAYER SHEAR ALONG/AHEAD OF THE FRONT. THIS WILL TEND TO LIMIT
STORM ORGANIZATION TO SOME EXTENT, BUT MODERATE TO LOCALLY STRONG
BUOYANCY AND STEEPENING LOW-LEVEL LAPSE RATES WILL SUPPORT A THREAT
OF ISOLATED HAIL AND DAMAGING GUSTS WITH THE STRONGEST STORMS THIS
AFTERNOON.
