AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
636 PM CDT WED JUL 25 2012

.AVIATION...
FOR THE 00Z KAMA TAF...BIGGEST CONCERN WILL BE THE TIMING AND IMPACT OF
TSRA. THERE IS AT LEAST A SLIGHT CHANCE OF TSRA THROUGH THE ENTIRE
TAF PERIOD...BUT THINK THE HIGHEST RISK WILL BE NOW THROUGH THE
ARRIVAL OF THE COLD FRONT...WHICH SHOULD BE AROUND 09Z.
ADDITIONALLY...INSTABILITY LOOKS TO DECREASE AFTER SUNSET...SO
BETWEEN 03 AND 09Z...MUCH OF THE ACTIVITY MAY BE MORE SHRA THAN TSRA.
THERE IS A POTENTIAL FOR REDEVELOPMENT BEHIND THE FRONT AFTER
12Z...BUT COVERAGE WILL BE ISOLATED SO WILL NOT MENTION IN THE TAFS
FOR NOW. WITH ANY STORMS THAT DEVELOP...VRB AND GUSTY WINDS AS WELL
AS MVFR VISIBILITIES ARE POSSIBLE.

FOR THE 00Z KGUY AND KDHT TAFS...THE COLD FRONT IS NEARLY ON TOP OF
BOTH TAF SITES. THUS...EXPECT THE HIGHEST RISK OF TSRA TO BE FROM NOW
THROUGH 06Z...WHEN THE FRONT SHOULD BE WELL SOUTH OF THE SITES. THERE
IS THE POTENTIAL THAT ISOLATED TSRA COULD REDEVELOP BEHIND THE
FRONT...BUT COVERAGE WILL BE VERY LIMITED...SO WILL NOT MENTION IN
THE TAFS FOR NOW. WITH ANY STORMS THAT DEVELOP...VRB AND GUSTY WINDS
AS WELL AS MVFR VISIBILITIES ARE POSSIBLE.

.PREV DISCUSSION... /ISSUED 314 PM CDT WED JUL 25 2012/

DISCUSSION...
A COLD FRONT IS POISED TO MOVE ACROSS THE PANHANDLES OVER THE NEXT 30 HOURS.
CURRENT SURFACE OBS SHOWS THE FRONT STRETCHED FROM DODGE CITY...KANSAS
TO EVA...OKLAHOMA TO AMISTAD...NEW MEXICO. ISOLATED TO SCATTERED
SHOWERS AND THUNDERSTORMS ARE EXPECTED TO FORM ALONG AND AHEAD OF THE
FRONT THIS EVENING. WHILE THE SEVERE THREAT REMAINS LOW...AN ISOLATED
SEVERE STORM...WITH WIND GUSTS UP TO 60 MPH...CAN'T BE RULED
OUT. THERE IS ALSO A POTENTIAL FOR LOCALLY HEAVY DOWNPOURS DUE TO
MODEST PWATS VALUES OF 1.10 TO 1.35 AND MBE VELOCITIES OF 5 TO 10
KTS. THE MAIN TIMING FOR THIS LOCALLY HEAVY RAIN IS FROM 6 PM
WEDNESDAY TO 6 AM THURSDAY WITH ISOLATED TOTALS NEAR 2 INCHES
POSSIBLE. MODEL SOLUTIONS AGREE ON A BRIEF REPRIEVE FROM SHOWERS AND
THUNDERSTORMS THURSDAY MORNING UNTIL MIDDAY. BY THIS POINT THE FRONT
WILL BE THROUGH MOST OF THE PANHANDLES WITH THE SOUTHERN MOST
COUNTIES OF THE CWA STILL HAVING RAIN CHANCES INTO THURSDAY
AFTERNOON. PWAT AND MBE VELOCITY VALUES REMAIN SIMILAR FOR THIS TIME
FRAME SO THE POTENTIAL FOR HEAVY RAIN WILL CONTINUE FOR THE SOUTHERN
TIER OF COUNTIES. BY THURSDAY NIGHT THE FRONT SHOULD BE COMPLETELY
THROUGH THE AREA...REFLECTING THE FASTER NAM SOLUTION. BY FRIDAY
MORNING THE UPPER RIDGE BUILDS BACK TO PUT A STOP TO RAIN CHANCES
THROUGH THE BETTER PART OF NEXT WEEK. MEXMOS VALUES STILL SEEM LOW
FOR THE HIGH TEMPERATURES UNDER THE RIDGE SO STUCK WITH THE ECMWF MAX
TEMPS FOR THIS TIME FRAME.

FIRE WEATHER...
NO ELEVATED FIRE WEATHER CONCERNS FOR THE NEXT SEVERAL DAYS. A COLD
FRONT MOVING THROUGH THE PANHANDLES OVER THE NEXT 30 HOURS WILL
PROVIDE RAIN CHANCES AND A WIND SHIFT TO THE NORTH-NORTHWEST. HOWEVER
WIDESPREAD WETTING RAINS ARE NOT EXPECTED WITH THIS SYSTEM. WINDS
WILL TURN BACK TO THE SOUTH BY THE WEEKEND.

.AMA WATCHES/WARNINGS/ADVISORIES...
