AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
1149 PM CST FRI MAR 8 2013

.AVIATION...DISCUSSION FOR 06Z TAFS

VFR CONDITIONS SHOULD PREVAIL FOR ALL SITES UNTIL TOWARD THE END OF
THE TAF PERIOD...WHEN MVFR CIGS ARE POSSIBLE BEHIND A COLD FRONT.

KAMA...
AN AREA OF THUNDERSTORMS WILL MOVE JUST SOUTH AND EAST OF THE
AIRPORT OVER THE NEXT HOUR...WITH -SHRA AND VCTS LIKELY SUFFICIENT
TO COVER SHOWERS. SHOWERS SHOULD START TO MOVE EAST OF THE AIRPORT
AFTER 08Z...THOUGH THEY COULD LINGER A BIT LONGER. ATTENTION WILL
THEN TURN TO STRONG AND GUSTY WSW WINDS SATURDAY WITH A FEW GUSTS
ABOVE 40 KTS LIKELY. A COLD FRONT WILL TURN WINDS TO THE NW AFTER
10/03Z AND POSSIBLY BRING MVFR CIGS AS WELL THOUGH CONFIDENCE IS TOO
LOW TO INCLUDE AT THIS FAR RANGE.

KDHT...
A FEW SHOWERS ARE POSSIBLE OVER THE NEXT 2 HOURS...BUT NO THUNDER IS
EXPECTED. WINDS WILL BE STRONG OUT OF THE WSW SATURDAY...TURNING TO
NW BEHIND A COLD FRONT AFTER 10/01Z. MVFR CIGS AND A FEW SNOW SHOWERS
WILL BE POSSIBLE BEHIND THE FRONT.

KGUY...
VFR CONDITIONS WILL PREVAIL TONIGHT WITH LIGHT WINDS AS MOST SHOWERS
SHOULD DANCE AROUND THE TAF SITE. WINDS WILL BE STRONG OUT OF THE WSW
SATURDAY...TURNING TO NW BEHIND A COLD FRONT AFTER 10/00Z. MVFR CIGS
AND A FEW SNOW SHOWERS WILL BE POSSIBLE BEHIND THE FRONT.

AVIATION...DISCUSSION FOR 00Z TAFS

THERE ARE TWO MAIN CONCERNS THIS TAF PERIOD...1. A CHANCE OF
CONVECTION AT AMARILLO THE FIRST 6 HOURS AND 2. VERY STRONG WINDS AT
ALL 3 SITES TOMORROW.

1. THE BEST CHANCE FOR CONVECTION AT KAMA WILL BE FROM 02Z-05Z. THINK
THE SHOT FOR AT LEAST LIGHT SHOWERS IS PRETTY GOOD...BUT WITH
THUNDER MORE UNLIKELY...HAVE CONTINUED TO JUST UTILIZE VCTS INSTEAD
OF PREVAILING THUNDER.

2. WINDS WILL PUSH 30 KTS SUSTAINED FROM MID MORNING THROUGH THE DAY
ON SATURDAY...WITH GUSTS PUSHING 40KTS. HAVE REFRAINED FROM AN
AVIATION WEATHER WARNING AT KAMA DUE TO THE POTENTIAL TO HAVE TO ISSUE
A CONVECTION RELATED AWW THIS EVENING.

MID AND HIGH CLOUDS WILL THICKEN LATE IN THE PERIOD...WITH LIGHT
PRECIP CHANCES RETURNING TO KGUY AND KDHT JUST PAST THE END OF THE
PERIOD.

SIMPSON

PREV DISCUSSION... /ISSUED 357 PM CST FRI MAR 8 2013/

DISCUSSION...
THROUGH TONIGHT: PARAMETERS LOOK TO BE COMING TOGETHER FOR SEVERE
WEATHER THIS EVENING AND TONIGHT. MODEST LOW-LEVEL SOUTHEASTERLY
FLOW HAS ADVECTED IN MODIFIED GULF MOISTURE INTO THE SOUTHERN HIGH
PLAINS TODAY. 50-DEGREE DEW POINTS HAVE MADE IT TO THE CAPROCK
ESCARPMENT WITH MID-50 DEW POINTS ANALYZED ACROSS NORTHWEST TEXAS AND
THE FAR SOUTHEASTERN TEXAS PANHANDLE. IT APPEARS THAT THE MOISTURE
ADVECTION HAS GENERALLY OFFSET ANY VERTICAL MIXING TODAY, ESPECIALLY
EAST OF A PSEUDO-DRYLINE THAT EXTENDS FROM NEAR GUYMON TO AMARILLO TO
EAST OF LUBBOCK. THIS PSEUDO-DRYLINE IS EXPECTED TO RETREAT SLIGHTLY
WESTWARD THIS EVENING BEFORE A PACIFIC COLD FRONT OVERTAKES IT
TONIGHT AND PUSHES IT EASTWARD AGAIN. THE HIGHEST PRECIPITATION
CHANCES WILL BE CONFINED TO THE EAST OF THIS MOISTURE GRADIENT.
CUMULUS HAVE DEVELOPED AHEAD OF AND BEHIND THE PSEUDO-DRYLINE THIS
AFTERNOON, BUT VISUAL OBSERVATIONS AND FORECAST SOUNDINGS SUGGEST THE
AIR MASS REMAINS CAPPED DUE TO THE ELEVATED MIXED LAYER PRESENT ON
REGIONAL MORNING SOUNDINGS. HIGH RESOLUTION MODELS AND ENSEMBLE
MEMBERS, INCLUDING THE TEXAS TECH WRF, SPC WRF, OUN WRF, AND SPC
SSEO, INDICATE WE MAY SEE SOME HIGH-BASED SHOWERS/POSSIBLY A
THUNDERSTORM AFTER 5 PM IN THE DRIER AIR MASS BEHIND THE PSEUDO-
DRYLINE. IF THIS ACTIVITY DEVELOPS, GUSTY WINDS IN EXCESS OF 50 MPH
WILL BE THE MAIN HAZARD GIVEN THE DEEPLY MIXED AIR MASS. IF THIS
ACTIVITY DEVELOPS, IT COULD TRANSITION TO A HYBRID SUPERCELLULAR
STRUCTURE AS IT MOVES INTO DEEPER MOISTURE AND AN INCREASINGLY
UNSTABLE AIR MASS EAST OF THE MOISTURE GRADIENT (MIXED LAYER CAPES
BETWEEN 500 AND 1000 J/KG). EVEN IF THIS SCENARIO DOES NOT
TRANSPIRE, ADDITIONAL CONVECTION IS EXPECTED TO DEVELOP AFTER 8 PM,
MAINLY EAST OF A GUYMON TO HEREFORD LINE AS STRONGER FORCING ARRIVES
FROM NEW MEXICO. WHEN THIS CONVECTION INITIATES, WE MAY SEE A FEW
SPLITTING SUPERCELLS BASED ON THE SHAPE OF FORECAST HODOGRAPHS. LARGE
HAIL UP TO THE SIZE OF GOLF BALLS LOOKS TO BE THE PRIMARY HAZARD WITH
THIS FIRST ROUND OF ACTIVITY, BUT DAMAGING WINDS AND ISOLATED
TORNADOES WILL ALSO BE A LOW-END THREAT. THE DAMAGING WIND AND
ISOLATED TORNADO THREAT IS STRICTLY BASED ON WHETHER ANY STORMS CAN
REMAIN SURFACE- BASED ONCE THE SUN SETS. CLIMATOLOGY SUGGESTS THERE
IS VERY LOW CHANCE (LESS THAN 1%) OF SEEING ANY TORNADOES AFTER 9 PM,
BUT THERE ARE A FEW FACTORS THAT ARGUE AGAINST CLIMATOLOGY. MOISTURE
ADVECTION WILL CONTINUE OVERNIGHT, WHICH MAY TEND TO OFFSET THE
DEVELOPMENT OF THE NOCTURNAL INVERSION UNTIL LATE TONIGHT. IN FACT,
RAP AND NAM FORECAST SOUNDINGS INDICATE THE NOCTURNAL INVERSION MAY
NOT FULLY SET IN UNTIL AFTER 2 AM FOR LOCATIONS SOUTH AND EAST OF A
CLAUDE TO PAMPA TO CANADIAN LINE. IF THIS IS INDEED THE CASE, LOW
CLOUD BASES, ENLARGED HODOGRAPHS IN THE LOWEST 1 KM, AND BUOYANCY IN
THE LOWEST 3 KM WILL CERTAINLY SUPPORT A TORNADO THREAT. ONCE AGAIN,
WE MUST REITERATE THAT THE TORNADO THREAT DEPENDS ENTIRELY ON WHETHER
THE STORMS CAN REMAIN ROOTED IN THE BOUNDARY LAYER. A SECOND ROUND OF
STORMS WILL LIKELY DEVELOP AFTER MIDNIGHT ACROSS THE SOUTH PLAINS AND
MOVE NORTHEAST INTO THE SOUTHEASTERN QUADRANT OF OUR FORECAST AREA.
THIS CONVECTION WILL LIKELY BE A BROKEN LINE OF CONVECTION. LARGE
HAIL WILL BE THE PRIMARY HAZARD, BUT A WIND THREAT WILL EVOLVE IF A
COLD POOL CAN BECOME ESTABLISHED. CONVECTION IS EXPECTED TO WANE
SLIGHTLY IN INTENSITY AFTER 3 AM, BUT THERE COULD STILL BE AN
ISOLATED SEVERE STORM THROUGH 6 AM.

SATURDAY-SATURDAY NIGHT: A DRY SLOT WILL SWEEP EASTWARD ACROSS THE
FORECAST AREA TOMORROW MORNING WITH THUNDERSTORM CHANCES QUICKLY
ENDING FROM WEST TO EAST. A FEW LINGERING SHOWERS AND STORMS WILL
LINGER IN THE EAST 11 AM, BUT ALL STORMS WILL LIKELY BE EAST OF THE
AREA AFTER THIS TIME. A COLD FRONT WILL ENTER THE OKLAHOMA PANHANDLE
DURING THE LATE AFTERNOON HOURS AND STEADILY MARCH SOUTHWARD. VERY
STRONG SOUTHWESTERLY WINDS BETWEEN 30 AND 40 MPH WITH GUSTS
POTENTIALLY UP TO 60 MPH WILL DEVELOP AHEAD OF THE FRONT. A WIND
ADVISORY WILL BE NEEDED FOR MUCH OF THE AREA FROM 11 AM THROUGH 7 PM.
SOME AREAS MAY EVEN MEET HIGH WIND WARNING CRITERIA, ESPECIALLY ON
THE CAPROCK. DUE TO THE STRONG WINDS, BLOWING DUST CAN BE EXPECTED TO
MOVE INTO THE PANHANDLES FROM EASTERN NEW MEXICO DURING THE AFTERNOON
WITH VISIBILITIES POSSIBLY BEING REDUCED BELOW 2 MILES AT TIMES. THE
LOWEST VISIBILITIES WILL BE CONFINED TO LOCATIONS ON THE CAPROCK.
MOISTURE WILL INCREASE BEHIND THE FRONT AND THERE MAY BE SOME LIGHT
RAIN SHOWERS ACROSS THE NORTHWEST AFTER 3 PM.

SATURDAY NIGHT: PRECIPITATION CHANCES WILL SPREAD SOUTHWARD SATURDAY
EVENING. IT STILL LOOKS LIKE THERE WILL BE A LIGHT RAIN/SNOW MIX
BEHIND THE COLD FRONT SATURDAY EVENING AND SATURDAY NIGHT NORTH OF A
ADRIAN TO CANADIAN LINE. MAINLY ALL SNOW IS EXPECTED AFTER MIDNIGHT
BEFORE THE SNOW ENDS BY SUNRISE SUNDAY AS DRIER AIR MOVES INTO THE
AREA. ANY SNOWFALL ACCUMULATIONS WILL REMAIN BELOW 1 INCH. DUE TO THE
STRONG NORTHERLY WINDS CONTINUING OVERNIGHT, BLOWING SNOW MAY REDUCE
VISIBILITIES BELOW 1 MILE AT TIMES.

SUNDAY-FRIDAY: NO MAJOR CHANGES MADE TO THIS TIME FRAME. TEMPERATURES
WILL REBOUND ON MONDAY WITH SEASONABLY WARM AND DRY CONDITIONS
EXPECTED TUESDAY-THURSDAY DUE TO DRY NORTHWEST FLOW ALOFT.

JACKSON

FIRE WEATHER...
ON SATURDAY, RELATIVE HUMIDITY VALUES WILL DROP BETWEEN 15 AND 20
PERCENT ACROSS THE SOUTHERN HALF OF THE TEXAS PANHANDLE AS
SOUTHWESTERLY 20 FOOT WINDS INCREASE INTO THE 25 TO 35 MPH RANGE.
EXPECTED RAINFALL ON TONIGHT AND THE MOIST NATURE OF THE FUELS IS
EXPECTED TO MITIGATE MAJOR FIRE CONCERNS. HOWEVER, A FIRE DANGER
STATEMENT WILL LIKELY BE ISSUED FOR SATURDAY DUE TO THE STRENGTH OF
THE WINDS AND THE LOWER RELATIVE HUMIDITY VALUES. A COLD FRONT WILL
SHIFT WINDS TO THE NORTH LATE SATURDAY AFTERNOON AND EVENING WITH
SPEEDS REMAINING BETWEEN 15 AND 25 MPH BEHIND THE FRONT. RELATIVE
HUMIDITY VALUES WILL REMAIN ABOVE 20 PERCENT ON SUNDAY SO NO ELEVATED
OR CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED.
