HAZARDOUS WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
542 AM CDT SUN APR 30 2000

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS TODAY AND TONIGHT
FOR WESTERN SECTIONS OF NORTH CENTRAL TEXAS...GENERALLY WEST OF A
GRAHAM...RANGER...COMANCHE LINE.  THE MODERATE RISK INCLUDES THESE
COMMUNITIES...ALONG WITH BRECKENRIDGE AND EASTLAND.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS TODAY AND TONIGHT...
EAST OF THE MODERATE RISK...AND GENERALLY WEST OF A SHERMAN...DALLAS
...WACO...TEMPLE LINE.  THE SLIGHT RISK INCLUDES THE DALLAS FORT
WORTH AREA...MINERAL WELLS...WEATHERFORD...AND DENTON.

THE MAIN THREATS FROM TODAYS STORMS WILL BE FROM LARGE HAIL AND
DAMAGING WINDS.  A FEW SUPERCELL TORNADOES ARE POSSIBLE THIS
AFTERNOON AND EVENING...MAINLY IN THE MODERATE RISK AREA.  HEAVY
RAIN MAY BECOME A THREAT BY TONIGHT OVER NORTHWEST SECTIONS OF NORTH
TEXAS...AND ACROSS THE ENTIRE AREA ON MONDAY.

EARLY DAY THUNDERSTORMS HAVE LEFT AN OUTFLOW BOUNDARY FROM JUST SOUTH
OF FORT WORTH TO BETWEEN ABILENE AND SAN ANGELO.  THIS BOUNDARY
SHOULD MOVE SLIGHTLY TO THE NORTH THIS AFTERNOON...UNLESS ADDITIONAL
MORNING STORMS PUSH IT SOUTHWARD.  BY AFTERNOON A SURFACE LOW
PRESSURE CENTER WILL STRENGTHEN ALONG THE DRY LINE SOUTHEAST OF
LUBBOCK. THE GREATEST THREAT OF TORNADIC STORMS LIKELY WILL BE EAST
OF THE SURFACE LOW...AND IN THE VICINITY OF THE OUTFLOW BOUNDARY.

AGAIN...MORNING STORMS COULD CHANGE THE CONFIGURATION OF OUTFLOW
BOUNDARIES...SUCH THAT THE AREA OF THE GREATEST SEVERE WEATHER
THREAT IS CHANGED SIGNIFICANTLY.

IN ADDITION TO THE THREAT OF SEVERE STORMS...THERE IS A WIND
ADVISORY TODAY FOR THE WESTERN TWO THIRDS OF NORTH CENTRAL TEXAS.
SOUTHEAST AND SOUTH WINDS OF 20 TO 30 MPH WILL CREATE HAZARDOUS
CONDITIONS ON LAKES AND FOR HIGH-PROFILE VEHICLES ON EAST-WEST
ORIENTED ROADS.  AN UPDATED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED
AROUND NOON.
