AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
1141 PM CDT MON SEP 17 2012

.AVIATION...
FOR THE 06Z TAFS...LITTLE CHANGE TO PREVIOUS AVIATION AFD REASONING.
SFC HIGH PRESSURE BUILDING INTO THE REGION TONIGHT WILL CAUSE WINDS
TO GRADUALLY DECREASE IN SPEEDS...THEN BECOME SW AROUND 10 KTS OR
LESS AFTER SUNRISE TUESDAY AS THIS SFC HIGH PRESSURE SLIDES OFF TO

DECREASE BY MIDDAY TUESDAY. VFR CONDITIONS ANTICIPATED NEXT 24 HOURS

.PREV DISCUSSION... /ISSUED 1001 PM CDT MON SEP 17 2012/

UPDATE...

HAVE MADE A FAIRLY SUBSTANTIAL EVENING UPDATE AS SAT/RAD OBS TRENDS
ALL POINT TO IMMINENT RAIN IN HARTLEY...OLDHAM...AND DEAF SMITH
COUNTIES. A COMPACT AND MODEL UNDER FORECAST MID LVL VORT IS
CURRENTLY CROSSING FROM COLORADO INTO NE NM AND ASCENT IN ADVANCE OF
IT IS PROMOTING A BAND OF LIGHT TO MODERATE RAIN. RECENT OBS IN NM
SHOW THAT THE MID LVL RADAR RETURNS ARE IN FACT REACHING THE GROUND
AS RATON PICKED UP OVER A QUARTER INCH OF RAIN WITHOUT EVEN SEEING A
THUNDERSTORM. GIVEN THE CURRENT TRAJECTORY...THE HEAVIER RAIN SHOULD
MISS AMARILLO TO THE WEST...THOUGH LIGHT RAIN IS QUITE POSSIBLE IN
THE METRO. MUCAPE VALUES ARE LESS THAN 25 J/KG AND THE LAST LIGHTNING
STRIKE WAS ALMOST 3 HRS AGO...SO REMOVED THUNDER FROM THE FCST AND
HWO.

LOWS TONIGHT WILL LIKELY BE HELD UP BY INCREASED CLOUD COVER AND
BUMPED LOWS UP BY ABOUT 3 DEGREES OVERNIGHT. CLOUDS AND PRECIP SHOULD
CLEAR THE SRN PANHANDLES BY AROUND DAYBREAK TUE.

PREV DISCUSSION... /ISSUED 621 PM CDT MON SEP 17 2012/

AVIATION...
FOR THE 00Z TAFS...SFC COLD FRONT IS WELL SOUTH OF THE TX AND OK
PNHDLS. NORTH WINDS WILL CONTINUE TO DECREASE IN SPEEDS THIS
EVENING AS SFC HIGH PRESSURE BUILDS INTO THE REGION. WINDS ARE
EXPECTED TO BECOME SW AFTER SUNRISE TUESDAY AS THE SFC HIGH MOVES OFF
TO THE E AND S OF FCST AREA. SOME MID AND HIGH LEVEL CLOUDS
ANTICIPATED AS WELL. TSTM POTENTIAL THIS EVENING REMAINS LOW...WITH
CONFIDENCE EVEN LOWER THAT ANY TAF SITE WILL BE AFFECTED. AS A
RESULT... HAVE LEFT MENTION OUT OF THIS FCST CYCLE. GENERALLY VFR
CONDITIONS NEXT 24 HOURS AT ALL TAF SITES.

ANDRADE

PREV DISCUSSION... /ISSUED 315 PM CDT MON SEP 17 2012/

DISCUSSION...
NO REAL CHANGE FROM EARLIER FORECAST.  THIS EVENING LOOKS TO BE OUR
BEST OPPORTUNITY FOR THUNDERSTORMS...AS STRONG JET STREAK DROPS
SOUTHEAST INTO PANHANDLES.  HAVE INCREASED POPS SLIGHTLY ACROSS
SOUTHERN TEXAS PANHANDLE...AS CONVERGENCE ALONG 850 MB FRONT MAY
ENHANCE DEVELOPMENT.  LOW POPS RETAINED AFTER MIDNIGHT ACROSS FAR
SOUTHERN ZONES...WITH NO POPS THEREAFTER.

SURFACE WINDS EXPECTED TO DIMINISH QUICKLY THIS EVENING.  MOST
LOCATIONS EXPECTED TO DROP INTO 40 TONIGHT AS CLEARING OCCURS AND
HIGH PRESSURE SETTLES IN.  SOUTH WINDS RESUME ON TUESDAY...WITH MAX
TEMPERATURES CLOSE TO CLIMO.  SOUTHWEST WINDS ON WEDNESDAY ALLOW
FOR A WARM DAY...WITH MAX TEMPERATURES REACHING THE LOWER 90S IN
MANY SECTIONS.

MODELS ARE STILL NOT IN GOOD AGREEMENT THEREAFTER...REGARDING
SURFACE FEATURES.  WEAK COLD FRONT IS FORECAST TO MOVE INTO NORTHERN
SECTIONS WEDNESDAY NIGHT...WITH THIS FEATURE DISSIPATING ON
THURSDAY.  INCREASING CLOUDS HOWEVER...ESPECIALLY ACROSS NORTHERN
ZONES...WILL KEEP TEMPERATURES AT BAY.  STRONGER COLD FRONT ON
FRIDAY ALLOWS FOR NOTICABLE COOLING FRIDAY THROUGH SUNDAY...WITH
MODEST WARMUP COMMENCING ON MONDAY.  03

FIRE WEATHER...
NORTH WINDS WILL QUICKLY DIMINISH THIS EVENING...BECOMING LIGHT AND
VARIABLE BEFORE SUNRISE.  SOUTH AND SOUTHWEST WINDS ON TUESDAY WILL
NOT BE STRONG.  SOUTHWEST WINDS EARLY WEDNESDAY WILL TREND TO
SOUTHEAST...AND WILL DIMINISH DURING THE AFTERNOON.  NO ELEVATED OR
CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED THROUGH MONDAY...AS
