AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
705 PM CDT TUE MAY 10 2011
.AVIATION...
00Z TAFS...AS HAS BEEN THE CASE LATELY...STRONG WINDS WILL BE THE
MAIN AVIATION CONCERN THROUGH THE NEXT 24 HOURS. GUSTY SOUTH/SOUTHWEST
WINDS AT THE THREE TERMINALS EARLY THIS EVENING WILL BACK TO THE
SOUTHEAST AFTER SUNSET AROUND SURFACE LOW OVER SOUTHEAST CO AS
MID/UPPER LEVEL LOW APPROACHES FROM THE WEST. WILL LOSE MUCH OF THE
GUSTINESS AFTER SUNSET AS THE BOUNDARY LAYER STARTS TO
DECOUPLE...HOWEVER WINDS WILL STILL REMAIN BREEZY WITH SUSTAINED
SPEEDS CLOSE TO 20 KTS. THE DRYLINE WILL RETREAT WESTWARD LATER THIS
EVENING THROUGH EARLY OVERNIGHT...LIKELY PUSHING JUST WEST OF KGUY
AND KAMA BUT REMAINING EAST OF KDHT. BETTER POTENTIAL FOR ANY LOW
CLOUDS HOWEVER LOOKS TO REMAIN EAST OF THE TERMINALS...SO WILL
MAINTAIN VFR CONDITIONS AT ALL THREE TERMINALS WITH JUST SOME MID TO
HIGH CLOUDS EXPECTED. WINDS WILL THEN VEER BACK TO THE SOUTHWEST
AROUND 08-09Z AS THE SURFACE LOW STARTS TO SHIFT EAST/NORTHEAST AHEAD
OF EJECTING MID/UPPER LOW. THIS WILL PUSH THE DRYLINE AND ANY THREAT
FOR LOW CLOUDS EAST OF THE TERMINALS DURING THE PRE DAWN HOURS. COULD
SEE SOME GUSTS TO AROUND 25 KTS ONCE THE SOUTHWEST WINDS RETURN LATE
TONIGHT. SOUTHWEST WINDS WILL THEN FURTHER INCREASE DURING THE DAY ON
WEDNESDAY AS MIXING INCREASES...REACHING SPEEDS OF 20-25 KTS WITH
GUSTS AOA 30 KTS MID TO LATE MORNING...BEFORE FURTHER INCREASING
DURING THE AFTERNOON TO NEAR 30 KTS WITH GUSTS NEAR 40 KTS. MAY NEED
AN AWW FOR KAMA WEDNESDAY AFTERNOON...BUT WILL NOT ISSUE YET AS IT
CURRENTLY LOOKS MARGINAL. ONE FINAL NOTE...THE WESTERN EDGE OF A
40-50 KT LLJ WILL BE POSITIONED OVER KAMA AND KGUY BETWEEN ROUGHLY
04Z AND 09Z TONIGHT. WILL REFRAIN FROM LLWS MENTION ATTM AS SURFACE WINDS
LOOK TO STAY STRONG ENOUGH TO KEEP MAGNITUDE OF LLWS BELOW
MENTIONABLE LEVELS...BUT WILL CONTINUE TO MONITOR.

.PREV DISCUSSION... /ISSUED 407 PM CDT TUE MAY 10 2011/
DISCUSSION...
FORECAST CONCERNS THIS AFTERNOON REVOLVE AROUND CONVECTION IN THE
EAST TONIGHT...FIRE WEATHER THE REMAINDER OF THIS AFTERNOON AND
TOMORROW...AND WINDS ON WEDNESDAY.
DRYLINE HAS BEEN PARKED IN THE EASTERN ZONES THIS AFTERNOON...WITH
SURFACE DEWPOINTS IN THE 50S AND 60S ALONG AND EAST OF A LINE FROM
CANADIAN TO WELLINGTON. CONVERGENCE ALONG THE DRYLINE HAS LED TO
SOME THUNDERSTORMS ACROSS THE EASTERN STACK OF COUNTIES AND WILL
CONTINUE THE THUNDERSTORM CHANCES IN THE EAST THROUGH 06Z.
CONFIDENCE IS LOWER ON EXTENDING POPS BACK TO THE WEST AS DRYLINE
RETREATS TONIGHT...SO WILL REFRAIN FROM INSERTING POPS BACK ONTO THE
CAPROCK COUNTIES FOR TONIGHT. LATEST SPC MESOANALYSIS PAINTS MLCAPES
BETWEEN 500 AND 1000 JOULES OUT EAST AND THIS COULD SUPPORT SOME
STRONG STORMS WITH SOME HAIL. BELIEVE THE DRYLINE WILL RETREAT
FURTHER WESTWARD THAN PREVIOUS THOUGHT AND HAVE RAISED TEMPS AND
DEWPOINTS FOR THE OVERNIGHT HOURS. SIDED CLOSER TO THE WARMER MET
NUMBERS AS THE MAV HAS BEEN RUNNING WAY TOO COOL AT NIGHT RECENTLY.
UPPER LEVEL LOW OVER THE FOUR CORNERS REGION TONIGHT WILL EJECT
NORTHEASTWARD ACROSS THE AREA TOMORROW. DECREASING HEIGHTS IN
ADVANCE OF THIS SYSTEM WILL KEEP TEMPS A FEW DEGREES COOLER THAN
TODAY WITH LOWER 70S IN THE NORTHWEST TO MIDDLE 80S IN THE SOUTHEAST
TEXAS PANHANDLE. DRYLINE SHOULD GET A GOOD PUSH INTO OKLAHOMA
TOMORROW AS SOUTHWEST WINDS INCREASE DURING THE MORNING HOURS...
USHERING IN DEWPOINTS IN THE 20S. SILENT POPS WILL CONTINUE FOR
WEDNESDAY AS BETTER CHANCES FOR STORMS WILL REMAIN WELL EAST INTO
OKLAHOMA. THE ONE EXCEPTION MAY BE ACROSS THE FAR WESTERN PARTS OF
THE OKLAHOMA PANHANDLE AS UPPER LOW SWINGS THROUGH...BUT WILL OMIT
FOR NOW. REGARDING THE WIND...MIXING TO NEAR OR SLIGHTLY ABOVE 600MB
SHOULD BE ABLE TO MIX DOWN SOME OF THE STRONGER WINDS ALOFT. LIKE
YESTERDAY...MAV AND MET ARE AT ODDS ON THE WIND SPEEDS FOR TOMORROW.
MAV REMAINS STRONGER OF THE TWO WITH WIND ADVISORY LEVEL SPEEDS
WHILE THE MET DOESNT QUITE ADVERTISE 30 KNOTS. WILL KEEP WINDS JUST
BELOW WIND ADVISORY LEVELS AND WILL LET THE MIDNIGHT SHIFT TAKE ONE
MORE LOOK AT THINGS. WINDS AROUND 30 TO 35 MPH WITH GUSTS BETWEEN 45
AND 50 COULD BE POSSIBLE DURING THE AFTERNOON HOURS.
COLD FRONT STILL ON TRACK TO MOVE THROUGH THE REGION WEDNESDAY
NIGHT...WITH A REINFORCING SURGE ON THURSDAY. COOLER TEMPS CAN BE
EXPECTED ON THURSDAY AS SURFACE HIGH SETTLES INTO THE REGION.
BLOCKING PATTERN TO BECOME ESTABLISHED INTO THE WEEKEND...WITH QUIET
WEATHER PREVAILING. LATEST MEX TEMPS IN THE EXTENDED APPEAR WAY TOO
COOL AND HAVE INCREASED TEMPS IN MOST PERIOD BY A FEW DEGREES. 12Z
GFS TRIES TO SNEAK A DISTURBANCE INTO THE REGION SATURDAY NIGHT AND
SUNDAY WITH SOME QPF ACROSS THE AREA. THINK THE PROSPECTS AT THIS
POINT ARE TOO SLIM TO MENTION IN THE FORECAST.
FIRE WEATHER...
A DRYLINE WILL PUSH EAST INTO WESTERN OKLAHOMA BY WEDNESDAY
AFTERNOON WHILE A COLD FRONT APPROACHES THE NORTHWEST SECTIONS OF
THE PANHANDLES BY LATE WEDNESDAY. CRITICAL FIRE WEATHER CONDITIONS
ARE EXPECTED TO DEVELOP ACROSS ALL OF THE PANHANDLES BY MIDDAY
WEDNESDAY. BEHIND THE COLD FRONT ON THURSDAY...RELATIVE HUMIDITIES
SHOULD REMAIN ABOVE 20 PERCENT WHILE WIND SPEEDS REMAIN LESS THAN 15
TO 20 MPH. FIRE WEATHER CONDITIONS ARE EXPECTED TO BE BELOW ELEVATED
LEVELS AT THIS TIME.
