AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE FORT WORTH TX
1224 AM CDT WED JUN 15 2011

.AVIATION UPDATED...
ADJUSTED THE DFW METROPLEX TAFS BEFORE ISSUING THE 06Z TAF SET TO
ACCOUNT FOR OUTFLOW BOUNDARY REACHING THE TAF SITES AND INCLUDE
MENTION OF THUNDER. NORTH WINDS WILL OCCUR BEHIND THE OUTFLOW
BOUNDARY BUT SHOULD RETURN TO A SOUTHERLY DIRECTION BY 08Z. THIS
ACTIVITY IS NOT EXPECTED TO PERSIST MUCH PAST 08Z. NOT MUCH
PRECIPITATION IS REACHING THE GROUND WITH THIS STORM BUT SOME SMALL
HAIL MAY OCCUR. THE MAIN THREAT WILL BE LIGHTNING WHICH HAS
ALREADY IGNITED SEVERAL GRASS FIRES AND THE POTENTIAL FOR STRONG
DOWNBURST WINDS.

.../PREVIOUS AVIATION DISCUSSION/...
ISOLATED THUNDERSTORMS MAY LINGER A FEW MORE HOURS OVER NORTHERN
COUNTIES...BUT SHOULD HAVE LITTLE IMPACT AT AREA TERMINALS ASIDE
FROM THICK HIGH BLOW-OFF FROM CB ANVILS. AT THE SURFACE...SOUTH
WINDS WILL CONTINUE THROUGH THE OVERNIGHT HOURS. GUIDANCE
CONTINUES TO INDICATE THE FORMATION OF SOME MVFR STRATUS MAINLY
OVER THE SOUTHERN HALF OF THE AREA BEFORE DAYBREAK. WILL CONTINUE
WITH THE BKN015 AT KACT BUT WILL KEEP THE LAYER SCATTERED IN
METROPLEX AREA TAFS DURING THE 10-15Z TIME. OTHERWISE SIMILAR
CONDITIONS EXPECTED DURING THE DAY WEDNESDAY...WITH PERHAPS
SOMEWHAT LIGHTER SOUTH WINDS. NAM IS HINTING AT SOME ISOLATED
THUNDERSTORMS AGAIN TOMORROW AFTERNOON AS FRONT STALLS OVER
NORTHERN PORTIONS OF THE AREA. THE POSSIBILITY IS THERE BUT FEEL
MOISTURE IS TOO LIMITED FOR DEVELOPMENT TO BE SIGNIFICANT ENOUGH
TO MENTION IN FORECASTS AT THIS TIME.

.PREV DISCUSSION... /ISSUED 830 PM CDT TUE JUN 14 2011/

...MESOSCALE FORECAST UPDATE...

REGIONAL RADARS INDICATE A LINE OF THUNDERSTORMS HAS DEVELOPED
ALONG A WEAK COLD FRONT EXTENDING FROM NEAR OKLAHOMA CITY
SOUTHWEST TOWARDS FREDERICK WITH MORE ISOLATED ACTIVITY TRYING TO
DEVELOP NORTH AND WEST OF ABILENE NEAR THE DRYLINE. THIS ACTIVITY
HAS BEEN AIDED BY SOME WEAK LARGE SCALE FORCING FOR ASCENT
ASSOCIATED WITH A SHORTWAVE TROUGH CURRENTLY OVER THE OK PANHANDLE
MOVING SOUTHEAST. REGIONAL SFC OBSERVATIONS INDICATE THAT WINDS
OVER MUCH OF NORTH TX HAVE BACKED AROUND TO THE SOUTH
SOUTHEAST...LIKELY IN RESPONSE TO WEAK CYCLOGENESIS NEAR THE
DRYLINE/COLD FRONT INTERSECTION IN NORTH CENTRAL TX. THIS BACKING
OF THE LOW LEVEL FLOW WAS PROVIDING SOME CONVERGENCE ALONG THE
COLD FRONT AND LIKELY AIDING IN THE MAINTENANCE OF TSTMS BY
INCREASING LOW LEVEL WIND SHEAR WHICH INTERACTS FAVORABLY WITH
TSTM OUTFLOW. 00Z FWD SOUNDING INDICATES A LAYER OF VERY DRY AIR
IN THE H800 TO H600 LAYER CHARACTERIZED BY RH VALUES OF 10 PERCENT
OR LESS.

CURRENT THINKING REGARDING CONVECTION IN NORTH CENTRAL TX IS THAT
IT WILL STRUGGLE TO SUSTAIN ITSELF AS IT MOVES EAST TOWARDS THE
CWA THIS EVENING. AS THIS ACTIVITY ATTEMPTS TO MOVE AWAY FROM THE
WEAK COLD FRONT IT WILL MOVE AWAY FROM THE STRONGEST APPARENT
SOURCE OF FORCING FOR ASCENT. THE LOSS OF DAYTIME HEATING AND THE
TSTM ACTIVITY MOVING INTO THE VERY DRY MID LEVEL AIRMASS IN PLACE
OVER MUCH OF NORTH TX INDICATES THAT THIS ACTIVITY WILL LIKELY
DISSIPATE SHORTLY AFTER SUNSET. AS STORMS MOVE TOWARDS OR INTO THE
CWA THIS EVENING...THEY WILL BE CAPABLE OF PRODUCING STRONG
OUTFLOW WINDS AS EVAPORATIVELY COOLED AIR ENHANCES DOWNDRAFT
STRENGTH. LIGHT PRECIPITATION FALLING OUT OF THE ANVIL REGION OF
THE TSTMS MAY ALSO PRODUCE SOME GUSTY WINDS OUT AHEAD OF THE TSTMS
THIS EVENING.

IF THE STORM IN BAYLOR COUNTY MAINTAINS STRENGTH AS IT MOVES
TOWARDS YOUNG...JACK...OR MONTAGUE COUNTIES...IT WILL BE CAPABLE
OF PRODUCING A SMALL SWATH OF HAIL. OVERALL THE PRIMARY HAZARDS
POSED BY THESE STORMS WOULD APPEAR TO BE LIGHTNING STRIKES
POSSIBLY CAUSING GRASS/BRUSH FIRES TO IGNITE...AND THEN
STRONG...POSSIBLY DAMAGING OUTFLOW WINDS RESULTING FROM THE STORMS
COLLAPSING INTO DRY AIR OVER NORTH TX. BECAUSE STORMS ARE EXPECTED
TO DISSIPATE AS THEY MOVE INTO NORTH TX...DID NOT CHANGE THE POPS
FROM THE 10 PERCENT PREVIOUS SHIFT HAD GOING. UNFORTUNATELY THIS
CURRENT ACTIVITY LOOKS MORE LIKELY TO PRODUCE STRONG WINDS THAN
SUBSTANTIAL RAINFALL OVER THE NORTHWESTERN PORTION OF THE CWA.
