AVIATION...
00Z TAF PACKAGE
THIS TAF PACKAGE WILL MAINTAIN VFR CONDITIONS BUT SEVERAL
DISRUPTIONS TO THE FORECAST ARE POSSIBLE IN THE NEXT 24 HOURS...IN
THE FORM OF SHOWERS AND THUNDERSTORMS. SHOWERS AND THUNDERSTORMS
HAVE ALREADY ERUPTED IN OKLAHOMA AND CONTINUE TO DROP SOUTH. BASED
ON THEIR CURRENT TRACKS...THESE SHOWERS AND STORMS WILL MISS THE
AIRPORTS AND WILL LEAVE MENTION OUT OF TAF SITES EXCEPT FOR KDAL.
WILL INCLUDE VCSH IN KDAL FROM 02-06Z AND CONTINUE TO MONITOR ALL
METROPLEX SITES THROUGH THE NIGHT. A BOUNDARY LIES NORTH OF THE
METROPLEX AND ADDITIONAL DEVELOPMENT IS LIKELY ALONG THIS BOUNDARY
THROUGH THE EVENING HOURS. WILL ALSO NEED TO MONITOR STRONG
STORMS IN SOUTHWEST OKLAHOMA. ADDITIONAL STORMS ARE POSSIBLE
TOMORROW AFTERNOON AND WILL INCLUDE A PROB30 GROUP IN THE
METROPLEX AFTER 18Z.

WINDS IN THE METROPLEX HAVE BACKED TO THE EAST-SOUTHEAST AND WILL
GENERALLY REMAIN IN A SOUTHEAST DIRECTION THROUGH THE TAF PERIOD.
WINDS MAY OCCASIONALLY TURN MORE SOUTH-SOUTHEAST BUT SHOULD BE
TEMPORARY. ON THE OTHER HAND...WACO WILL MAINTAIN MORE OF A SOUTH
TO SOUTHEAST DIRECTION. ONLY CLOUDS EXPECTED AT THIS TIME ARE
BLOW-OFF MID AND HIGH LEVEL CLOUDS FROM CONVECTION TO THE NORTH.

PREV DISCUSSION... /ISSUED 342 PM CDT MON JUN 16 2008/

DISCUSSION...NOT MUCH CHANGE TO THE PREVIOUS FORECAST WITH UPPER
RIDGE IN PLACE ACROSS THE SOUTHWESTERN US. THERE IS A FRONTAL
BOUNDARY DRAPED ACROSS NORTHERN OKLAHOMA INTO THE TEXAS PANHANDLE
THIS AFTERNOON AND THUNDERSTORMS ARE BEGINNING TO INITIATE ACROSS
WESTERN OKLAHOMA. RIDGE AXIS HAS SHOWN SOME RETROGRESSION WESTWARD
OVER THE LAST 24 HOURS AND CONFIDENCE THAT THUNDERSTORMS CAN MAKE
IT WELL INTO THE CWA IS INCREASING...HOWEVER...THINK BETTER
CHANCES WILL BE TOMORROW EVENING INTO THE NIGHTTIME HOURS WHEN
STEERING FLOW BECOMES MORE NORTH-NORTHWEST AND INSTABILITY AXIS IS
POSITIONED MORE FAVORABLY OVER NORTH CENTRAL TEXAS. THAT BEING
SAID...MODELS HAVE COMPLETELY BACKED OFF OF THIS SCENARIO AND KEEP
BETTER THUNDERSTORM CHANCES FOR TONIGHT INTO EARLY TUESDAY. FOR
NOW...WILL CONTINUE TO MONITOR CONVECTION TO THE NORTH BUT THINK
ACTIVITY WILL WEAKEN ONCE AGAIN AS IT APPROACHES THE RED RIVER.
WILL HAVE SOME 30/40 POPS ALONG THE RED RIVER COUNTIES FOR
TONIGHT. ALTHOUGH THE GUIDANCE DOESNT GENERATE SIGNIFICANT PRECIP
FOR TOMORROW...WILL CONTINUE WITH HIGHER POPS LATE TOMORROW AFTN
AND TOMORROW NIGHT. CONDITIONS APPEAR MORE FAVORABLE FOR AN MCS TO
MAKE IT ACROSS THE RED RIVER BRINGING MUCH NEEDED RAIN AND
THUNDERSTORMS TO THE AREA. THERE IS A SLIGHT RISK FOR SEVERE
THUNDERSTORMS BOTH TONIGHT AND ON TUESDAY GENERALLY NORTH OF
INTERSTATE 20.

RAIN CHANCES DONT LOOK OVERLY IMPRESSIVE BEYOND EARLY WEDNESDAY
RIGHT NOW...BUT WITH NORTHWEST FLOW ALOFT PREVAILING AND ANOTHER
WEAK FRONT SLATED TO BE SOMEWHERE ACROSS THE SOUTHERN PLAINS BY
FRIDAY...WILL HAVE TO CONTINUE TO MONITOR FOR POTENTIAL NOCTURNAL
MCS ACTIVITY. OTHERWISE...TEMPS WILL CONTINUE 5-10 DEGREES ABOVE
NORMAL THROUGH THE END OF THE WEEK.
