VALID 180908Z - 181015Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH
718...719...720...CONTINUES.
A FAST MOVING LINE OF STORMS EXTENDED FROM NEAR MTO TO E OF MVN TO W
OF PAH. SHORTWAVE TROUGH LIFTING NEWD THROUGH MO AND STRONG
ENVIRONMENTAL WINDS...INCLUDING 50-70 KT MID LEVEL WINDS...WERE
FAVORABLE FOR WIND DAMAGE. HOWEVER...STRONG LOW LEVEL SHEAR COMBINED
WITH SURFACE DEWPOINTS IN THE MID AND UPPER 60S ALSO INDICATES A
TORNADO OR TWO IS POSSIBLE WITHIN THE LINE...AS IT MOVES ENEWD AT
50-55 KT.
MORE ISOLATED STORMS WERE LOCATED ACROSS FAR ERN AR/WRN TN AND NRN
MS. THESE MORE DISCRETE STORMS...WITHIN THE STRONGLY LOW/MID LEVEL
SHEARED ENVIRONMENT SUGGESTS THE TORNADO THREAT MAY BE A LITTLE
GREATER WITH THE ACTIVITY MOVING THROUGH IL AND WRN KY.
