VALID 261751Z - 261845Z
SUSTAINED CLUSTER OF THUNDERSTORMS IS GRADUALLY INTENSIFYING OVER
ECNTRL IND...CLEARLY WITHIN THE WARM SECTOR AHEAD OF MAIN UPPER LOW.
THIS ACTIVITY IS LIFTING NEWD INTO A REGION OF MORE FOCUSED
CONFLUENCE NEAR THE SLOWLY RETREATING WARM FRONT. SHEAR PROFILES
APPEAR SUPPORTIVE OF SUPERCELLS DESPITE THE ONGOING ORGANIZED
MCS-TYPE STRUCTURE. THERE APPEARS TO BE SUFFICIENT LOW LEVEL
SHEAR/HELICITY FOR ISOLATED TORNADOES WHEN THESE STRONGER UPDRAFTS
INTERACT WITH AFOREMENTIONED WARM FRONTAL ZONE.
