MESOSCALE DISCUSSION 1849
NWS STORM PREDICTION CENTER NORMAN OK
0331 PM CDT WED JUL 30 2025
AREAS AFFECTED...CENTRAL WYOMING INTO SOUTHERN MONTANA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 302031Z - 302230Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...SCATTERED THUNDERSTORMS CAPABLE OF ISOLATED SEVERE HAIL
AND SEVERE WIND GUSTS WILL BE POSSIBLE THIS AFTERNOON INTO THE
EVENING. HOWEVER, GIVEN THAT WIDESPREAD SEVERE STORMS ARE NOT
EXPECTED AT THIS TIME, THE LIKELIHOOD OF WEATHER WATCH ISSUANCE IS
LOW.
DISCUSSION...SCATTERED THUNDERSTORM HAVE DEVELOPED ACROSS PORTIONS
OF WESTERN AND CENTRAL WYOMING THIS AFTERNOON, IN AN ENVIRONMENT
CHARACTERIZED BY 1000-1500 J/KG MUCAPE AND 45-40 KTS OF EFFECTIVE
DEEP-LAYER SHEAR. WHILE THERE IS SUFFICIENT SHEAR FOR SOME STORMS TO
BECOME MORE INTENSE AND ORGANIZED, THE EXPECTATION IS THAT ANY
SEVERE STORMS WILL LARGELY BE ISOLATED AND TRANSIENT IN NATURE. ANY
ORGANIZED CONVECTION WOULD BE CAPABLE OF 60 MPH WIND GUSTS AND ANY
HAIL IS EXPECTED TO REMAIN BELOW 2.00 INCHES IN SIZE.
WHILE THE PROBABILITY OF WATCH ISSUANCE IS EXPECTED TO REMAIN LOW,
CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED.
