MESOSCALE DISCUSSION 1781
NWS STORM PREDICTION CENTER NORMAN OK
1133 AM CDT TUE JUL 28 2026
AREAS AFFECTED...EASTERN KENTUCKY...SOUTHERN WEST VIRGINIA...WESTERN
VIRGINIA...WESTERN NORTH CAROLINA
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 281633Z - 281830Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...SEVERE POTENTIAL TO INCREASE THROUGH THE AFTERNOON.
DAMAGING WIND, LARGE HAIL, AND A FEW TORNADOES WILL BE POSSIBLE.
DISCUSSION...THUNDERSTORMS ACROSS WESTERN VIRGINIA HAVE SHOWN
TRANSIENT SUPERCELL CHARACTERISTICS OVER THE LAST COUPLE OF HOURS,
WITH MID-LEVEL ROTATION APPARENT ON RADAR. THESE WILL CONTINUE SOUTH
AND EAST THROUGH THE EARLY AFTERNOON WITH POTENTIAL FOR LARGE HAIL,
DAMAGING WIND, AND PERHAPS A TORNADO.
ADDITIONAL THUNDERSTORM ACTIVITY IS EXPECTED TO DEVELOP BACK TO THE
WEST NEAR THE COLD FRONT INTO EASTERN KENTUCKY AND SOUTHERN WEST
VIRGINIA. IN ADDITION TO STRONG DEEP LAYER SHEAR AROUND 45-55 KTS, A
25-30 KT LOW-LEVEL JET AXIS THROUGH THIS REGION WILL SUPPORT
INCREASING LOW-LEVEL SHEAR AND INCREASING CURVATURE OF LOW-LEVEL
HODOGRAPHS. THIS WILL SUPPORT POTENTIAL FOR SUPERCELLS AND POTENTIAL
FOR A FEW TORNADOES WHERE SUPERCELLS CAN BE MAINTAINED. GUIDANCE
SUGGESTS STORM MODE MAY BE MIXED, WITH CLUSTERS/BOWING SEGMENTS AND
SUPERCELLS. THIS LEADS TO SOME UNCERTAINTY IN HOW LONG MORE DISCRETE
SUPERCELLS WILL BE MAINTAINED, WITH POTENTIAL FOR DAMAGING WIND AND
HAIL TO BE THE HIGHEST CONFIDENCE THREAT. A WATCH WILL BE NEEDED TO
COVER THIS POTENTIAL BY THE AFTERNOON.
