SEVERE WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FT WORTH TX
1250 PM CDT FRI APR 12 1991

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
TONIGHT OVER THAT PART OF NORTH TEXAS NORTHWEST OF A BOWIE-BRECKENRIDGE
-ABILENE LINE. THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER THE
REMAINDER OF NORTH TEXAS THROUGH TONIGHT.

THUNDERSTORMS THAT DEVELOP WILL HAVE THE POTENTIAL TO PRODUCE LARGE
HAIL...DAMAGING WINDS...FLASH FLOODING...AND POSSIBLY A FEW TORNADOES.

THE ATMOSPHERE IS EXTREMELY UNSTABLE OVER NORTH TEXAS AGAIN TODAY.
THE COMBINATION OF INSTABILITY AND MODERATE VERTICAL WIND SHEAR
SUGGESTS THAT STORMS WILL HAVE THE POTENTIAL TO PRODUCE BOTH SEVERE
WEATHER AND FLASH FLOODING.

THERE ARE TWO FOCUSING ELEMENTS FOR SEVERE THUNDERSTORM DEVELOPMENT
THIS AFTERNOON...A STATIONARY OUTFLOW BOUNDARY LEFT FROM LAST NIGHT'S
STORMS THAT WAS NEAR A MINERAL WELLS-DALLAS-TYLER LINE AT NOON
...AND A DRY LINE THAT WAS MOVING  EAST FROM A CHILDRESS-ABILENE-
SAN ANGELO LINE. A TORNADO WATCH HAS BEEN ISSUED TIL 4 PM ALONG THE
OUTFLOW BOUNDARY FROM DALLAS EASTWARD...WITH ADDITIONAL WATCHES
POSSIBLE LATER THIS AFTERNOON.

THE NATIONAL WEATHER SERVICE EMPHASIZES THAT ALL OF NORTH TEXAS IS
UNDER A SEVERE WEATHER THREAT. HOWEVER...IF APPEARS THAT SOME OF THE
STRONGEST STORMS MAY FORM NEAR THE INTERSECTION OF THE OUTFLOW
BOUNDARY AND THE DRY LINE...GENERALLY IN THE AREA BETWEEN FORT WORTH...
WICHITA FALLS...AND ABILENE. IF STORMS FORM IN THIS AREA THEY WILL
LIKELY BECOME SEVERE AND MOVE EAST ALONG THE OUTFLOW BOUNDARY.

A FLASH FLOOD WATCH IS IN EFFECT FOR THAT PART OF NORTH TEXAS EAST OF
A GAINESVILLE-GLEN ROSE LINE...AND NORTH OF A GLEN ROSE-CARTHAGE LINE
...MAINLY FOR STORMS THAT FORM NEAR OR NORTH OF THE OUTFLOW BOUNDARY.

EMERGENCY MANAGEMENT OFFICIALS AND STORM SPOTTER SHOULD KEEP INFORMED
OF WEATHER TODAY AND BE PREPARED FOR POSSIBLE ACTIVATION...MAINLY THIS
AFT;ERNOON AND TONIGHT.

SEVERE WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FT WORTH TX
320 PM CDT FRI APR 12 1991

THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS THROUGH TONIGHT NORTHWEST
OF A GAINESVILLE-MINERAL WELLS-ABILENE LINE. ADJACENT TO THE HIGH RISK
THERE IS A MODERATE RISK NORTHWEST OF A SHERMAN-30 MILES SOUTHEAST OF
DALLAS-BROWNWOOD LINE...AND A SLIGHT RISK OVER THE REST OF NORTH TEXAS.

THUNDERSTORMS THAT DEVELOP WILL HAVE THE POTENTIAL TO PRODUCE LARGE
HAIL...DAMAGING WINDS...FLASH FLOODING...AND POSSIBLY A FEW TORNADOES.

LIFTED INDICES ARE BELOW -10 IN WEST AND CENTRAL PORTIONS OF NORTH
TEXAS. THE COMBINATION OF EXTREME INSTABILITY AND MODERATE VERTICAL
WIND SHEARS SUGGESTS THAT SEVERE WEATHER AND FLASH FLOODING ARE LIKELY
OVER PORTIONS OF NORTH TEXAS THROUGH TONIGHT.

AT 3PM THUNDERSTORMS WERE FORMING RAPIDLY IN ERATH COUNTY...ABOUT 60
MILES SOUTHWEST OF FORT WORTH. THIS STORM COMPLEX WAS PART OF A ZONE
OF DEVELOPING THUNDERSTORMS THAT EXTENDED NORTH INTO OKLAHOMA. THESE
STORMS WERE FORMING AHEAD OF A DRY LINE WHICH HAD ADVANCED EAST TO
NEAR A CHILDRESS-COLEMAN LINE AT 3 PM. FURTHERMORE...THE OLD OUTFLOW
BOUNDARY...SITUATED NEAR A JACKSBORO-FORT WORTH-TYLER LINE COULD SERVE
TO HELP INTENSIFY STORMS THAT APPROACH FROM THE WEST.

STORMS SPOTTERS AND EMERGENCY PREPAREDNESS OFFICIALS SHOULD PREPARE
FOR LATE AFTERNOON/EVENING ACTIVATION. SPOTTERS IN DALLAS...TARRANT...
PARKER...ERATH...HOOD...JOHNSON...WISE...PALO PINTO...AND DENTON
COUNTIES CAN EXPECT ACTIVATION WITHIN THE NEXT SEVERAL HOURS.

...HILL AND MCLENNAN COUNTIES...

AT 340 PM CDT WACO WEATHER RADAR SHOWED NO PRECIPITATION OCCURING IN CENTRAL

STEPHENVILLE.  MOVEMENT WAS TO THE NORTHEAST AT 25 MPH.

WHILE NO SEVERE WEATHER WAS NOTED...RESIDENTS OF CENTRAL TEXAS SHOULD BE ON
THE LOOKOUT FOR DEVELOPING THUNDERSTORMS LATER THIS AFTERNOON AND EVENING.
SOME OF THE STORMS WILL BE CAPABLE OF PRODUCING VERY HEAVY RAIN...STRONG
GUSTY WIND...DANGEROUS LIGHTNING AND LARGE HAIL.  TORNADOES WILL ALSO BE
POSSIBLE IN SOME AREAS.

A SURFACE FRONT AND DRYLINE CURRENTLY LOCATED TO THE WEST OF THE AREA WILL
SERVE AS THE FOCUS FOR SEVERE WEATHER.  THE VERTICLE WIND PROFILES ALSO<
INDICATE THAT SOME OF THE STORMS WXILL HAVE THE POTENTIAL TO PRODUCE FLOODING
AND FLASH FLOODING.

RESIDENTS OF CENTRAL TEXAS SHOULD STAY TUNED TO NOAA WEATHER RADIO FOR
FURTHER INFORMATION ON THIS POTENTIALLY DANGEROUS WEATHER SITUATION.
