AREA FORECAST DISCUSSION...UPDATED FOR AVIATION
NATIONAL WEATHER SERVICE FORT WORTH TX
513 PM CDT WED MAY 3 2000

THUNDERSTORMS MAY DEVELOP LATE THIS AFTERNOON/EVENING ACROSS CENTRAL
PARTS OF NORTH TEXAS..BUT BEST CHANCE WILL BE EASTERN AND
NORTHEASTERN AREAS NORTH OF BOUNDARY THAT MOVED THROUGH DFW
METROPLEX THIS MORNING.  ANOTHER BOUNDARY ON THE VISIBLE SATELLITE
FROM NORTHWEST TARRANT COUNTY TO NEAR EASTLAND TO NEAR SWEETWATER
MAY BECOME ANOTHER BOUNDARY FOR STORMS TO FORM ON...AS CUMULUS FIELD
IS BECOMING ENHANCED ALONG THIS LINE.  60+ DEWPOINTS SPREADING
NORTHWESTWARD...AND MOST OF NORTH TEXAS WILL HAVE AN AMPLE SURFACE-
BASED MOISTURE SUPPLY FOR WIDELY SCATTERED TO SCATTERED THUNDERSTORMS
THE REST OF THE WEEK AS WEAK UPPER LEVEL DISTURBANCES MOVE AROUND THE
WEST SIDE OF THE UPPER LOW CURRENTLY OVER NORTHEAST TEXAS.  WILL
RAISE OVERNIGHT LOW TEMPS DUE TO HIGHER DEWPOINTS...OTHERWISE NO
CHANGES TO TEMPS.

DFW 62/80/65/85 2322    ACT 66/84/67/87 4423

.FTW...SOME STORM POSSIBLY SEVERE REMAINDER OF THE AFTERNOON AND
       THIS EVENING AREAWIDE.

...AVIATION DISCUSSION...
TONIGHT SHOULD BE SIMILAR TO YESTERDAY WITH POTENTIAL FOR
THUNDERSTORMS TO LINGER AROUND AIRPORTS MUCH OF THE NIGHT. WILL TRY
TO INDICATE THIS WITH MENTION OF CB IN CLOUD TYPE AND NOT BLANKET
THUNDER AT AIRPORTS ALL NIGHT. PRECIP CHANCES WILL LINGER INTO
TOMORROW AFTERNOON AS H5 LOW TRUDGES SLOWLY EAST. 807

HAZARDOUS WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
340 PM CDT WED MAY 3 2000

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
EVENING...MAINLY SOUTH OF AN EASTLAND...MINERAL WELLS...FORT
WORTH...DALLAS...TO TERRELL LINE.  THE SLIGHT RISK AREA INCLUDES
EASTLAND...DALLAS...FORT WORTH...WACO...CANTON...ATHENS...
WAXAHACHIE...AND PALESTINE.  OUTSIDE OF THE SLIGHT RISK AREA...
SHOWERS AND THUNDERSTORMS ARE POSSIBLE...BUT WILL LIKELY REMAIN BELOW
SEVERE LIMITS.

AN UPPER LEVEL LOW PRESSURE CENTER NEAR THE RED RIVER HAS RESULTED
IN UNSTABLE AIR OVER NORTH TEXAS.  IN ADDITION...THUNDERSTORMS FROM
THIS MORNING HAVE PRODUCED NUMEROUS OUTFLOW BOUNDARIES...WHICH WILL
ACT AS AREAS FOR DEVELOPMENT OF THUNDERSTORMS. ONE SUCH BOUNDARY
IS LOCATED ALONG AN EASTLAND...TO FORT WORTH...TO DALLAS LINE BY
MID AFTERNOON.  AS THE UPPER LEVEL DISTURBANCE INTERACTS WITH THE
ABUNDANT LOW LEVEL MOISTURE...THUNDERSTORMS THAT DO DEVELOP...CAN
QUICKLY GO SEVERE.

THE VERTICAL WIND PROFILES SHOW TURNING OF THE WINDS WITH HEIGHT...
AND THIS WILL ALLOW SUPERCELL THUNDERSTORMS TO DEVELOP THIS AFTERNOON
AND EVENING. THE MAIN THREAT FROM THE THUNDERSTORMS WILL BE LARGE
HAIL...DAMAGING WINDS...AND A FEW TORNADOES.

LIMITING FACTORS FOR SEVERE THUNDERSTORMS WILL BE AREAS OF CLOUD
COVER FROM MORNING THUNDERSTORMS WHICH WILL TEMPORARILY STABILIZE
THE ATMOSPHERE.  OTHER LIMITING FACTORS FOR THE DEVELOPMENT OF
TORNADOES WILL BE A WIND SPEED MINIMUM IN THE LOWEST LEVELS OF THE
ATMOSPHERE...WHICH WILL HELP KEEP THE TORNADO THREAT TO A FEW SHORT
LIVED TORNADOES.

THUNDERSTORMS ARE EXPECTED TO DEVELOP BETWEEN 4 AND 7 PM ACROSS
NORTH CENTRAL TEXAS...AND THEN MOVE INTO CENTRAL AND EAST TEXAS
AFTER 7 PM. SPOTTERS AND EMERGENCY MANAGERS SHOULD STAY INFORMED OF
RAPIDLY CHANGING WEATHER THIS AFTERNOON.  SPOTTER GROUPS NORTH OF
EASTLAND...HILLSBORO...TO TERRELL...CAN EXPECT POSSIBLE ACTIVATION
BETWEEN 4 AND 7 PM.  SPOTTER GROUPS SOUTH OF EASTLAND...HILLSBORO...
TO TERRELL...CAN EXPECT POSSIBLE ACTIVATION AFTER 7 PM.
