ISOLATED THREAT OF DMGG WINDS THIS AFTERNOON/EVENING ACROSS THE
HIGHER TERRAIN OF CNTRL ID/SWRN MT. A WW IS NOT ANTICIPATED.
CU FIELD HAS INCREASED OVER THE HIGHER TERRAIN AS DIURNAL HEATING
LEADS TO WEAK DESTABILIZATION. HEIGHT FALLS WITH THE APPROACH OF A
STRONG/COLD UPPER TROUGH AND ADEQUATE MID LEVEL MOISTURE SHOULD
SUPPORT CONTINUED HIGH-BASED THUNDERSTORM DEVELOPMENT. DESPITE
MODEST MID LEVEL FLOW /40 KT/...WEAK INSTABILITY SHOULD LIMIT
OVERALL SEVERITY OF STORMS...WITH AN ISOLATED THREAT OF DMGG WINDS
AS DRY LOW LEVELS/EVAPORATIVE COOLING ENHANCE DOWNDRAFT WINDS.
