...SEVERE WEATHER OUTLOOK...

A STRONG STORM SYSTEM THAT HAS BEEN RESPONSIBLE FOR WIDESPREAD SEVERE
WEATHER ACROSS THE PLAINS AND OHIO VALLEY REGIONS THIS WEEKEND WILL
CONTINUE TO MOVE EAST OVERNIGHT. ASSOCIATED WITH THIS SYSTEM...A LINE
OF STRONG TO SEVERE THUNDERSTORMS EXTENDED FROM NORTHERN INDIANA
TO EAST TEXAS LATE SUNDAY EVENING. TORNADO WATCHES EXTENDED AS FAR
EAST AS EASTERN TENNESSEE AND KENTUCKY. THE LINE OF STORMS WILL
CONTINUE TO TRACK EAST OVERNIGHT...REACHING THE MOUNTAINS OF THE
WESTERN CAROLINAS AND NORTHEAST GEORGIA AROUND SUNRISE.

AS THE LINE OF STORMS MOVES FURTHER EAST...IT IS EXPECTED TO
ENCOUNTER INCREASINGLY STABLE AIR. THIS MAY RESULT IN SOME GRADUAL
WEAKENING WITH TIME. NEVERTHELESS...THE STORMS ARE EXPECTED TO
MAINTAIN ENOUGH INTENSITY TO POSE A SEVERE WEATHER THREAT AS THEY
MOVE OVER THE MOUNTAINS MONDAY MORNING. THE MOST LIKELY FORM OF
SEVERE WEATHER WILL BE DAMAGING STRAIGHT LINE WINDS. HOWEVER...AN
ISOLATED TORNADO CANNOT BE RULED OUT.

THE STORMS ARE EXPECTED TO MOVE OFF THE BLUE RIDGE BY LATE MORNING...
SHIFTING THE THREAT OF SEVERE WEATHER TO THE FOOTHILLS AND PIEDMONT
DURING THE AFTERNOON.

SPOTTER GROUPS SHOULD BE PREPARED TO ACTIVATE QUICKLY ACROSS THE
MOUNTAINS MONDAY MORNING. SPOTTER ACTIVATION MAY BE REQUIRED ACROSS
THE FOOTHILLS AND PIEDMONT FROM LATE MORNING INTO THE AFTERNOON.
DISPATCHERS SHOULD ENSURE COUNTY EMERGENCY MANAGEMENT OFFICIALS ARE
AWARE OF THIS INFORMATION.
