600 PM CDT WED OCT 10 2001

AVIATION DISCUSSION...
AN OUTFLOW BOUNDARY WAS MOVING THROUGH THE METROPLEX AIRPORTS AT
23Z...EXTENDING JUST NORTHWEST OF A MCKINNEY...TO DFW TO 20 MILES
NORTHWEST OF GRANBURY.  THIS BOUNDARY WILL CONTINUE TO SLOWLY SLIDE
SOUTHEAST DURING THE NEXT COUPLE OF HOURS. THUNDERSTORMS 50 TO
90 MILES WEST OF DFW AT 23Z...WILL CONTINUE TO MOVE EAST AT 30
MPH...AND SHOULD ACROSS THE METROPLEX AIRPORTS BETWEEN 1 AND 4Z.
THUNDERSTORMS WILL LIKELY HOLD OFF UNTIL AFTER MIDNIGHT IN THE WACO
AREA...AS THE COLD FRONT NEARS. MVFR CIGS ALONG WITH MORE WIDESPREAD
SHOWERS AND THUNDERSTORMS ARE EXPECTED LATE TONIGHT INTO
THURSDAY.   58

250 PM CDT WED OCT 10 2001
SEVERE THREAT WILL CONTINUE ACROSS ALL OF CWA TONIGHT...WITH THE
GREATEST POTENTIAL FOR SEVERE WEATHER ACROSS THE NORTHWEST HALF OF
THE AREA THIS EVENING AND EARLY TONIGHT.  COLD FRONT WILL BECOME
QUASI STATIONARY ACROSS NORTH CENTRAL TEXAS THIS EVENING.  THIS WILL
RESULT IN A TRAIN ECHO PATTERN WHERE THE FRONT STOPS...AND A FLASH
FLOOD WATCH MAY BE NECESSARY SOMETIME TONIGHT.  CURRENT THINKING IS
HEAVIEST RAINS WILL BE ACROSS SOUTHEAST COUNTIES.  NEXT SHORT WAVE
IS MUCH STRONGER THAN THE ONE THAT WILL MOVE ACROSS THE AREA
TONIGHT.  AS A RESULT THE FRONT WILL BECOME STATIONARY ACROSS
SOUTHERN ZONES ON THURSDAY WITH A BACKING UPPER FLOW...AND WITH THE
UPPER FLOW BECOMING STRONG SOUTHWEST LATE THURSDAY NIGHT AND EARLY
FRIDAY STRONG ISENTROPIC LIFT WILL OCCUR ACROSS FRONT WITH
INCREASING CLOUDS AND AN INCREASING CHANCE OF THUNDERSTORMS FRIDAY

HAZARDOUS WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
400 PM CDT WED OCT 10 2001

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THROUGH THIS
EVENING OVER THE NORTHWESTERN HALF OF NORTH TEXAS...GENERALLY
NORTHWEST OF A LINE FROM PARIS...TO DALLAS...TO LAMPASAS. THIS
MODERATE RISK AREA INCLUDES THE CITIES OF GRAHAM...DENTON...
SHERMAN...EASTLAND...CLEBURNE...GOLDTHWAITE...MERIDIAN...AND THE
DALLAS-FORT WORTH METROPLEX.

THERE IS A SLIGHT RISK OF SEVERE WEATHER OVER THE REMAINDER OF NORTH
TEXAS TONIGHT.

A COLD FRONT...EXTENDING ALONG A MCALESTER OKLAHOMA...TO WICHITA
FALLS...TO LUBBOCK LINE LATE THIS AFTERNOON...WILL CONTINUE TO MOVE
SOUTH TONIGHT...PROVIDING THE FORCING MECHANISM FOR WIDESPREAD
THUNDERSTORMS.  WITH HELP FROM AN APPROACHING UPPER LEVEL
DISTURBANCE...STRONG TO SEVERE THUNDERSTORMS ARE EXPECTED GIVEN THE
FAVORABLE COMBINATION OF INSTABILITY AND WIND SHEAR.  LARGE HAIL AND
DAMAGING WINDS ARE THE LIKELY THREAT FOR SEVERE WEATHER THROUGH THE
EVENING.  ISOLATED TORNADOES ARE ALSO POSSIBLE WITHIN THE CURRENT
ENVIRONMENT.

AS THE FRONT SLOWS DOWN LATER TONIGHT...HEAVY RAIN WILL BECOME THE
PRIMARY THREAT OVER NORTH TEXAS...ESPECIALLY SOUTH OF A TEMPLE...TO
CANTON LINE.

ON FRIDAY...THERE APPEARS TO BE ANOTHER THREAT OF SEVERE WEATHER
OVER NORTH TEXAS.
