.PREV DISCUSSION... /ISSUED 1024 AM CDT THU SEP 16 2010/

UPDATE...
MOIST AND UNSTABLE AIR AND WEAK SHEAR WERE COMBINING TO PRODUCE STRONG
STORMS...PARTICULARLY ALONG AND EAST OF THE CAPROCK. UPDATED FORECAST
TO INCREASE COVERAGE. SEVERE POTENTIAL IS LOW AND IS BEING CLOSELY
MONITORED.

PREV DISCUSSION... /ISSUED 611 AM CDT THU SEP 16 2010/

AVIATION...
SOME AREAS OF MVFR TO IFR CIGS EXPECTED FIRST COUPLE TO FEW
HOURS...ESPECIALLY NRN TAF SITES. HAVE INCLUDED SUCH AT ALL SITES
EARLY IN THIS CYCLE. A BAND OF SHOWERS AND TSTMS MOVG THRU KGUY
SHOULD BE E OF THIS SITE BY 12Z. OTHERWISE...AFTER PERIOD OF LOW
CLOUDS THIS MORNING...VFR CONDITIONS EXPECTED. THREAT OF TSTMS
RETURNS LATER THIS AFTERNOON AND EVENING AND HAVE RETAINED MENTION OF
CB AT ALL SITES DURG THIS TIME FRAME AS CONFIDENCE REMAINS LOW AS TO
WHETHER OR NOT ANY PARTICULAR LOCATION WILL EXPERIENCE TSTMS.

ANDRADE

PREV DISCUSSION... /ISSUED 324 AM CDT THU SEP 16 2010/

DISCUSSION...
THE STATIONARY FRONT IS JUST SOUTH OF THE INTERSTATE 40 CORRIDOR.
THE FRONT HOWEVER...IS NOT EXPECTED TO REMAIN DISTINCT FOR LONG AS
ALL MODELS INDICATE THAT FRONTOLYSIS IS ONGOING AND THE FRONT SHOULD
VIRTUALLY WASH OUT BY THE END OF THE DAY TODAY. STILL COULD SEE
THUNDERSTORMS DEVELOP ALONG THE FRONT AND ANY REMNANT OUTFLOW
BOUNDARIES...ESPECIALLY AS THE LOW LEVEL EASTERLY FLOW HAS RESULTED
IN DEW POINTS ACROSS THE AREA GENERALLY IN THE 60S. THEREFORE...KEPT
SLIGHT CHANCE ACROSS THE AREA TODAY AND TONIGHT.

AFTER TODAY...THE DOMINANT FEATURE WILL BE THE UPPER LEVEL RIDGE
EXPECTED TO BUILD OVER THE SOUTH CENTRAL U.S. THROUGH EARLY NEXT WEEK.
BY FRIDAY NIGHT...A SECOND WEAK COLD FRONT IS EXPECTED TO APPROACH
THE REGION...BUT BOTH THE GFS AND NAM ARE IN AGREEMENT THAT THE FRONT
WILL STALL JUST NORTH OF THE REGION. THEREFORE...EXPECT MOSTLY
SOUTHERLY AND SOUTHWESTERLY LOW LEVEL FLOW THROUGH THE WEEKEND.
THEREFORE...HAVE FORECASTED MAX TEMPERATURES ABOVE GUIDANCE FOR BOTH
SATURDAY AND SUNDAY...WIDESPREAD 90S AND POSSIBLY NEAR RECORD HIGHS
WILL BE POSSIBLE. THE ONE POSSIBLE COMPLICATION IS THE VERY COLD
CONTINENTAL POLAR AIR MASS EXPECTED TO PUSH AS FAR SOUTH AS NEBRASKA
OVER THE WEEKEND. IF THE AIR MASS PROPAGATES FURTHER SOUTH...WHICH IS
POSSIBLE..BUT NOT PROBABLE GIVEN HOW SHALLOW IT IS AND THE TIME OF
YEAR...IT COULD RESULT IN COOLER WEATHER ACROSS THE SOUTHERN HIGH
PLAINS.

THE NEXT PROMISING COLD FRONT TO AFFECT THE AMA CWA IS EXPECTED
TUESDAY OR WEDNESDAY. KEPT THE PREVIOUS FORECAST SOLUTION OF
INCLUDING SLIGHT CHANCE POPS TUESDAY NIGHT AND WEDNESDAY.
HOWEVER...BOTH THE GFS AND ECMWF SHOWED A SLIGHTLY FASTER SOLUTION
WITH THE LATEST RUN. ONE CONCERN WITH THIS FRONT IS THAT THERE IS
LITTLE REFLECTION IN THE WIND FIELDS OF EITHER MODEL...AS THEY KEEP
MOSTLY SOUTHERLY WINDS OVER THE REGION THROUGH THE PERIOD. IN THE
EXTENDED KEPT TEMPERATURES CLOSE TO MEX GUIDANCE...GENERALLY IN THE
LOWER TO MID 80S...THOUGH THIS MAY BE TOO LOW GIVEN THE LACK OF
NORTHERLY FLOW AND HOW WEAK THE FRONT IS EXPECTED TO BE.

JOHNSON

FIRE WEATHER...
FIRE WEATHER CONCERNS SHOULD BE MINIMAL TODAY AS COOLER WEATHER WILL
MEAN RELATIVE HUMIDITY VALUES SHOULD REMAIN ABOVE 30 PERCENT. IN
ADDITION...WINDS SHOULD REMAIN RELATIVELY LIGHT...GENERALLY LESS THAN
15 MPH. BY SATURDAY...FIRE WEATHER CONCERNS MAY INCREASE AS
INCREASING TEMPERATURES WILL LEAD TO MINIMUM RELATIVE HUMIDITY VALUES
NEAR 20 PERCENT...AND SOUTHERLY WINDS WILL INCREASE TO 15 TO 20 MPH.
