0609 PM CDT THU JUN 26 2025
AREAS AFFECTED...PORTIONS OF EASTERN MONTANA INTO FAR NORTHWESTERN
NORTH DAKOTA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 262309Z - 270045Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A COUPLE INSTANCES OF SEVERE WIND AND/OR HAIL MAY
ACCOMPANY THE STRONGER, LONGER-LIVED STORMS. HOWEVER, THE OVERALL
SEVERE THREAT SHOULD REMAIN ISOLATED.
DISCUSSION...SCATTERED STRONG THUNDERSTORMS HAVE BEEN INCREASING
OVER THE LAST COUPLE OF HOURS, PARTICULARLY OVER SOUTHERN MT. ACROSS
THE NORTHERN HIGH PLAINS, STRONG SURFACE HEATING HAS SUPPORTED UPPER
80S TO 90 F SURFACE TEMPERATURES, AND WITH 9 C/KM LOW AND MID-LEVEL
LAPSE RATES IN PLACE, OVER 1000 J/KG MLCAPE HAS BECOME COMMONPLACE.
NONETHELESS, DEEP-LAYER FLOW AND SUBSEQUENT SHEAR REMAINS MODEST,
ESPECIALLY WHERE RICHER LOW-LEVEL MOISTURE AND RESULTANT INSTABILITY
ARE IN PLACE. THEREFORE, MULTICELLS AND TRANSIENT SUPERCELLS WILL
CONTINUE TO PERCOLATE IN INTENSITY OVER THE NEXT FEW HOURS. SEVERE
WIND AND HAIL ARE POSSIBLE, BUT SHOULD OCCUR ON A MORE INTERMITTENT
AND ISOLATED BASIS.
