HAZARDOUS WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
343 PM CST FRI MAR 10 2000

...WINDY CONDITIONS...

A WIND ADVISORY WILL BE IN EFFECT FOR ALL OF NORTH CENTRAL TEXAS
TONIGHT AS WIND SPEEDS RANGE FROM 20 TO 30 MPH...WITH HIGHER GUSTS.
BOATERS ARE URGED TO STAY CLOSE TO SHORE AS THE WIND WILL MAKE AREA
LAKES VERY CHOPPY AND HAZARDOUS. LIGHTWEIGHT OUTDOOR OBJECTS SHOULD
ALSO BE SECURED THIS AFTERNOON.

...SEVERE THUNDERSTORMS...

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS TONIGHT FOR THAT
PART OF NORTH TEXAS GENERALLY SOUTH OF A LINE FROM STEPHENVILLE...
TO CANTON.

A DRY LINE...SEPARATING DRIER AND HEAVIER AIR TO THE WEST FROM MOIST
AND BUOYANT AIR TO THE EAST...HAS CONTINUED TO TRIGGER THUNDERSTORM
DEVELOPMENT ACROSS SOUTHERN SECTIONS OF WEST TEXAS LATE THIS
AFTERNOON. THE ATMOSPHERE ACROSS THE OUTLOOK AREA REMAINS VERY
UNSTABLE AND THUNDERSTORMS ARE EXPECTED TO BECOME SEVERE AS A
STRONGER UPPER LEVEL DISTURBANCE MOVES IN FROM THE NORTHWEST THIS
EVENING.

FORECAST VERTICAL WIND PROFILES SUGGEST LARGE HAIL AND DAMAGING
WINDS WILL BE THE PRIMARY THREATS THIS EVENING. HOWEVER...THERE MAY
BE SUFFICIENT TURNING OF THE WINDS WITH HEIGHT TO ALLOW ISOLATED
TORNADOES TO BRIEFLY DEVELOP.

STORM SPOTTERS AND EMERGENCY MANAGERS IN THE OUTLOOK AREA SHOULD BE
PREPARED FOR POSSIBLE ACTIVATION EARLY THIS EVENING. SPOTTERS
SHOULD BE NEEDED WEST OF I-35 FIRST...ROUGHLY BETWEEN 4 AND 6 PM. AS
THE STORMS MOVE EAST...SPOTTERS WILL LIKELY BE NEEDED EAST OF I-35
AFTER 6 PM.
