AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
648 AM CDT FRI AUG 16 2013

.AVIATION...
/12Z TAFS/ CONVECTION OVER THE EASTERN TX PANHANDLE WILL STAY WELL
EAST OF THE TERMINALS. AREA OF LOW CLOUDS ASSOCIATED WITH THIS
CONVECTION /WITH BASES AROUND 5 KFT/ CONTINUE TO SPREAD FURTHER TO
THE WEST...NEAR THE KGUY AND KAMA TERMINALS. POSSIBLE FOR CIGS TO
LOWER TO 1KFT WITHIN THE NEXT HOUR OR SO BUT GIVEN THE GENERAL TREND
FOR VFR CIGS HAVE OPTED TO KEEP VFR CONDITIONS INTACT. LIGHT FOG HAS
DEVELOPED AT KGUY AND KDHT REDUCING VISBYS DOWN TO 5-6 MI. THIS FOG
SHOULD LIFT BY 15Z. SCT MID CLOUD DECK WILL DOMINATE DURING THE DAY
ALTHOUGH LOW CLOUDS CAN RETURN TO THE TERMINALS EARLY SAT MORNING.
POSSIBLE FOR CIGS TO LOWER TO MVFR OR EVEN IFR ALTHOUGH CONFIDENCE IS
TOO LOW AT THIS TIME TO MENTION THIS IN THE FORECAST. STORMS
DEVELOPING OVER THE PLAINS IN EASTERN NM CAN MOVE INTO THE WESTERN
PANHANDLES LATE THIS EVENING ALTHOUGH CONFIDENCE IN THIS OCCURRING IS
ALSO TOO LOW TO MENTION IN THE FORECAST ATTM.

.PREV DISCUSSION... /ISSUED 520 AM CDT FRI AUG 16 2013/

SHORT TERM...
EARLY MORNING WATER VAPOR SATELLITE IMAGERY DEPICTS A DISTINCT
SHORTWAVE TROUGH OVER WESTERN KS. AS THIS WAVE MOVES SOUTHWARD INTO
OK LATER THIS MORNING...EXPECT ONGOING MCS OVER THE EASTERN TX
PANHANDLE TO CONTINUE TO SLIDE SOUTH. THE PRESENCE OF A WEAK 30 KT
SOUTHWESTERLY LOW LEVEL JET CAN LEAD TO ADDITIONAL DEVELOPMENT OF
STORMS UPSTREAM OF THIS MCS ALTHOUGH LATEST RADAR TRENDS INDICATE
THIS SEEMS UNLIKELY. EXPECT ALL CONVECTION TO EXIT THE AREA BY MID
MORNING AS SUBSIDENCE BEHIND THIS DEPARTING WAVE SPREADS ACROSS THE
AREA. LATER TODAY HEIGHTS RISE OVER THE SOUTHERN PLAINS AS AN UPPER
TROUGH OVER THE EASTERN CONUS LIFTS FURTHER EAST. THIS DOES NOT BODE
WELL FOR PRECIP CHANCES AS DOES THE LACK OF ANY APPRECIABLE LIFT.
HOWEVER DID HOLD ONTO A SLIGHT CHANCE FOR STORMS OVER THE WESTERN AND
SOUTHERN TX PANHANDLE AS CONVECTION FIRING ON THE HIGHER TERRAIN OUT
WEST POSSIBLY MOVES INTO THIS AREA. BESIDE THE AFOREMENTIONED
NEGATIVES FOR PRECIP CHANCES...THE UPPER FLOW WILL VEER MORE TO THE
NORTH...COMPLICATING THE PROSPECT FOR STORMS TO MAKE THEIR WAY INTO
THE WESTERN PANHANDLES. HOWEVER A MOIST AND UNSTABLE AIR MASS REMAINS
IN PLACE WHICH SHOULD SUPPORT ANY ONGOING CONVECTION. HIGHS TODAY
WILL BE SIMILAR TO YESTERDAY...IN THE MID 80S TO AROUND 90.

LONG TERM...
THE UPPER RIDGE SLIDES FURTHER EASTWARD SATURDAY PRECIP CHANCES
REALLY START TO DWINDLE. HOWEVER UNLIKE TODAY A MORE DISTINCT
SHORTWAVE TROUGH WILL SLIDE SOUTHWARD ALONG THE EASTERN PERIPHERY OF
THE UPPER RIDGE SATURDAY EVENING. THIS CAN ALLOW FOR ISOLATED STORMS
TO PROPAGATE INTO THE WESTERN ZONES FROM THE HIGHER TERRAIN OUT WEST.
THE RIDGE EXPANDS FURTHER TO THE EAST EARLY NEXT WEEK WHERE IT WILL
REMAIN CENTERED OVER THE CENTRAL PLAINS FOR MUCH OF THE WEEK. THIS
WILL LEAD TO AN INCREASE IN TEMPS ALTHOUGH THEY WILL BE NEAR
SEASONAL NORMALS /IN THE LOW 90S/ DUE TO RECENT RAINFALL ACROSS THE
REGION. IN ADDITION PRECIP CHANCES LOOK PRETTY SLIM BEYOND SATURDAY
NIGHT ALTHOUGH THE GFS SUGGESTS THE POSSIBILITY FOR SHOWERS AND
THUNDERSTORMS BEYOND THE SCOPE OF THIS FORECAST AS IT SHOWS AND UPPER
LOW MOVING UNDERNEATH THE RIDGE WITH SURFACE WINDS VEERING TO AN
UPSLOPE SOUTHEASTERLY COMPONENT.

CLK

FIRE WEATHER...
NEITHER ELEVATED OR CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED
ACROSS THE TEXAS AND OKLAHOMA PANHANDLES FOR THE NEXT SEVEN DAYS
AS MINIMUM RELATIVE HUMIDITIES WILL STAY ABOVE 20 PERCENT. IN
ADDITION 20 FOOT WINDS WILL STAY BELOW 20 MPH. THE POSITION OF AN
UPPER RIDGE OVER THE FOUR CORNERS REGION WILL MAINTAIN NORTHWEST
UPPER LEVEL FLOW ACROSS THE AREA TODAY...LEADING TO ANOTHER
CHANCE FOR SHOWERS AND THUNDERSTORMS MAINLY OVER THE WESTERN AND
SOUTHERN TEXAS PANHANDLE THIS AFTERNOON AND TONIGHT AND SATURDAY
NIGHT. THIS RIDGE WILL EXPAND FURTHER TO THE EAST THIS WEEKEND AND
EARLY NEXT WEEK...GREATLY DIMINISHING ANY PROSPECTS FOR WETTING
RAINS.
