753 PM CDT WED JUN 20 2012

.UPDATE...
FRONT CONTINUES TO BE NEARLY STATIONARY...EXTENDING ALONG A LINE FROM
TEXLINE...TO JUST SOUTH OF GUYMON...TO MEAD KS. THUNDERSTORMS ARE
JUST BEGINNING TO DEVELOP ALONG THE PORTION OF THE FRONT IN THE
PANHANDLES...AND DO NOT SEEM TO BE PROPAGATING VERY FAR AWAY FROM THE
FRONT AT THIS TIME. STILL EXPECT TO SEE THE FRONT MAKE PROGRESS
SOUTH...ESPECIALLY AFTER SUNSET. HAVE UPDATED THE GRIDS TO REFLECT
THE CURRENT POSITION OF THE FRONT...AND THE EXPECTED EVOLUTION OVERNIGHT.

.PREV DISCUSSION... /ISSUED 619 PM CDT WED JUN 20 2012/

AVIATION...
COLD FRONT EXTENDS FROM THE EASTERN OKLAHOMA PANHANDLE INTO THE
EXTREME NORTHWEST TEXAS PANHANDLE. THE FRONT HAS MADE VERY LITTLE
PROGRESS SOUTHWARD THROUGH THE DAY. PLENTY OF MOISTURE AVAILABLE FOR
SHOWERS AND THUNDERSTORMS TO DEVELOP ALONG THE FRONTAL BOUNDARY...BUT
THUS FAR CONVECTION HAS BEEN SUPPRESSED. AS THE FRONT BEGINS TO MOVE
SOUTH...COULD SEE SOME THUNDERSTORMS DEVELOP AFTER 03Z...BUT
CONFIDENCE IS LOW. AS A RESULT...HAVE REMOVED MENTION OF SHOWERS AND
THUNDERSTORMS FROM ALL TAF SITES AS THIS WILL BE LARGELY DEPENDENT ON
WHETHER CONVECTIVE ACTIVITY GETS GOING THIS EVENING. OTHERWISE...WINDS
WILL BE BACKING TO THE NORTH AND NORTHEAST AS THE FRONTAL BOUNDARY
BEGINS TO PUSH SOUTH.

PREV DISCUSSION... /ISSUED 345 PM CDT WED JUN 20 2012/

DISCUSSION...
AFTERNOON VISIBLE SATELLITE IMAGERY SHOWS A STRONG COLD FRONT OVER
THE OK PANHANDLE AND THE NORTHWEST TX PANHANDLE. THIS FRONT APPEARS
TO HAVE SLOWED DOWN OR EVEN STALLED IN THIS AREA ALTHOUGH IT IS STILL
FORECAST TO PUSH SOUTH OF THE AREA BY THURSDAY MORNING. STRONG
CAPPING HAS HELD OFF ON CI ALONG THIS FRONT DESPITE STRONG DIURNAL
HEATING AND A MOIST AND UNSTABLE AIR MASS IN PLACE. THE CAP WILL
WEAKEN THIS EVENING AND TONIGHT WITH STORMS DEVELOPING ALONG AND
BEHIND THE FRONT. NORTHEAST UPSLOPE FLOW AND A 30 KT LOW-LEVEL JET
SOUTH OF THIS FRONT WILL MAINTAIN DECENT MOISTURE ACROSS THE AREA.
HOWEVER WEAK 0-6 KM WIND SHEAR SHOULD LIMIT THE THREAT OF ORGANIZED
SEVERE WX. DESPITE THIS...A FEW STORMS CAN BECOME SEVERE WHERE
NEARLY 30 DEGREE T/TD SPREADS SUGGEST STRONG WINDS WILL BE THE MAIN
HAZARD.

THE FRONT WILL PUSH SOUTH OF THE AMA FA THURSDAY MORNING WHERE THE
FRONT IS EXPECTED TO STALL. DIURNAL HEATING IMPINGING ON A MOIST AND
UNSTABLE AIR MASS CAN RESULT IN ADDITIONAL STORM DEVELOPMENT
THURSDAY ALTHOUGH EXPECT THE BEST CHANCES FOR STORMS WILL BE ACROSS
THE SOUTHERN TX PANHANDLE...CLOSEST TO WHERE THE FRONTAL BOUNDARY
LIES. UPSLOPE FLOW AND ABUNDANT CLOUD COVER WILL HOLD TEMPS DOWN IN
THE 80S. SURFACE HIGH PRESSURE WILL BUILD IN BEHIND THE FRONT WITH
PRECIP CHANCES ENDING THURSDAY EVENING.

WELL ADVERTISED UPPER RIDGE WILL BUILD OVER THE CENTRAL AND
SOUTHERN PLAINS FRIDAY AND WILL REMAIN OVER THE AREA INTO THE MIDDLE
OF NEXT WEEK. SUBSIDENCE UNDERNEATH THE RIDGE WILL KEEP PRECIP
CHANCES AT BAY. TEMPS WILL ALSO REBOUND BACK INTO THE 90S AND TO THE
TRIPLE DIGITS. HAVE GONE AND INCREASE HIGHS A LITTLE BIT ABOVE THE
MEX THROUGH THIS PERIOD. MONSOONAL MOISTURE WILL INCREASE AND CAN
RESULT IN A TYPICAL RING OF FIRE WX PATTERN AT THE END OF NEXT WEEK.
THE BEST CHANCES FOR STORMS LOOK TO STAY OVER THE MOUNTAINS IN NM.

CLK

FIRE WEATHER...
A COLD FRONT WILL PUSH SOUTH ACROSS THE TEXAS PANHANDLE TONIGHT.
UPSLOPE EAST TO SOUTHEAST WINDS BEHIND THE FRONT WILL MAINTAIN DECENT
BOUNDARY LAYER MOISTURE ACROSS THE REGION. WITH A MOIST AND
UNSTABLE AIR MASS IN PLACE...SHOWERS AND THUNDERSTORMS ARE EXPECTED
TO DEVELOP TONIGHT. THE FRONT WILL STALL NEAR THE SOUTHERN TX
PANHANDLE THURSDAY AND CAN PROVIDE A FOCUS FOR ADDITIONAL STORM
DEVELOPMENT THROUGH THURSDAY EVENING. AN EXPANSIVE UPPER RIDGE WILL
BUILD OVER THE CENTRAL AND SOUTHERN PLAINS FRIDAY AND IS EXPECTED
TO REMAIN IN THIS GENERAL LOCATION THROUGH AT LEAST THE MIDDLE OF
NEXT WEEK. HOT AND DRY WX CAN BE EXPECTED DUE TO THE POSITION OF
THIS RIDGE WHICH WILL RESULT IN AFTERNOON RELATIVE HUMIDITIES
FALLING TO AROUND 15 PERCENT...ESPECIALLY IN THE WESTERN SECTIONS.
HOWEVER WEAKER 20 FOOT WINDS SHOULD PRECLUDE ELEVATED OR CRITICAL
FIRE WEATHER CONDITIONS.
