SUMMARY...CLUSTERS OF STRONG TO LOCALLY SEVERE STORMS MAY PERSIST

AND THE WRN CAROLINAS APPEAR TO BE AT OR NEAR PEAK INTENSITY WITH
THE PRIMARY HAZARD BEING LOCALIZED DOWNBURSTS PRODUCING TREE DAMAGE.

WITH 0-6 KM VALUES OF ONLY 15-20 KT AT HTX/GSP. UPDRAFTS IN 5-9 KM

POSE A SOMEWHAT LONGER DURATION DAMAGING WIND RISK OVER ERN TN.
