AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
638 PM CDT THU JUL 9 2015

.AVIATION...
00Z TAFS...SCATTERED THUNDERSTORMS ARE MOVING INTO THE WESTERN
PANHANDLES THIS EVENING AND ARE EXPECTED TO CONTINUE MOVING EASTWARD
AND INCREASING IN COVERAGE. VFR CONDITIONS ARE EXPECTED OUTSIDE OF
CONVECTION...WHICH IS EXPECTED TO IMPACT THE TAF SITES THIS EVENING
AND A CHANCE REMAINS FOR CONVECTION THROUGH THE EARLY MORNING HOURS
ON FRIDAY. WINDS WILL REMAIN OUT OF THE SOUTH AT 8 TO 15 KTS...WITH
OCCASIONAL GUSTS TO 20 TO 25 KTS AND OF COURSE...VARIABLE AND GUSTY
WINDS NEAR THUNDERSTORMS.  LOW TO MEDIUM CONFIDENCE IN MVFR
CONDITIONS DEVELOPING IN THE MORNING...ESPECIALLY IN AREAS THAT
RECEIVED HIGHER RAINFALL.

ELSENHEIMER

&&

.PREV DISCUSSION... /ISSUED 407 PM CDT THU JUL 9 2015/

SHORT TERM...TODAY AND TONIGHT.

A WEAK SURFACE BOUNDARY REMAINS OVER THE OKLAHOMA PANHANDLE...AND
REMNANT OUTFLOW FROM CONVECTION EARLIER TODAY COULD ALSO PROVIDE
SOURCES OF LIFT THIS AFTERNOON. AMPLE SURFACE MOISTURE REMAINS IN
PLACE ACROSS THE AREA WITH DEWPOINTS IN THE LOW TO MID 60S.
CONVECTION STARTING TO FIRE ACROSS THE MOUNTAINS IN NEW MEXICO JUST
AHEAD OF THE NEXT UPPER LEVEL SHORTWAVE EXPECTED TO MOVE ACROSS THE
PANHANDLES TONIGHT. THIS PARTICULAR SHORTWAVE IS SOMEWHAT WEAKER THAN
THE ONE THAT BROUGHT US EXTENDED PERIODS OF SHOWERS AND THUNDERSTORMS
LAST NIGHT...HOWEVER...IT SHOULD STILL BE ENOUGH TO SUPPORT
THUNDERSTORMS WELL INTO THE EVENING HOURS AND OVERNIGHT. FOR THE
SEVERE THREAT...EFFECTIVE BULK SHEAR EXPECTED TO COME IN AROUND 30 KTS
THIS EVENING WHICH COULD SUPPORT SOME STRONG TO SEVERE STORMS. PLENTY
OF SURFACE BASED INSTABILITY IS EXPECTED TO BE AVAILABLE...THOUGH
CLOUD COVER HAS INCREASED SIGNIFICANTLY ACROSS THE AREA OVER THE PAST
FEW HOURS AND MAY LIMIT FURTHER HEATING. FORECAST SOUNDINGS SHOWING A
FAIR AMOUNT OF CAPE IN THE HAIL GROWTH ZONE SO ANY ORGANIZED
SUPERCELLS THAT CAN GET GOING COULD PRODUCE SOME LARGE
HAIL...HOWEVER...PWAT VALUES IN THE 1.25-1.75 RANGE INDICATE THAT
LOCALIZED FLOODING OR FLASH FLOODING COULD QUICKLY BECOME A CONCERN
FOR SLOWER MOVING OR TRAINING STORMS. DAMAGING WINDS ALSO ARE A
HAZARD FOR ANY SUPERCELLS...BUT ALSO IF STORMS CONGEAL AND CONTINUE
PROPAGATING ACROSS THE AREA DURING THE EVENING HOURS AS SOME MODELS
SUGGEST. AN ISOLATED TORNADO CANNOT BE RULED OUT BUT THE OVERALL
THREAT IS LOW.

ELSENHEIMER

LONG TERM...FRIDAY THROUGH NEXT THURSDAY.

THUNDERSTORM CHANCES WILL LINGER THROUGH FRIDAY NIGHT...AND CAN/T
RULE OUT A COUPLE OF ISOLATED STORMS SATURDAY AFTERNOON...BEFORE
UPPER RIDGING BRINGS A PERIOD OF WARMER/DRIER CONDITIONS.

SHOWERS AND EMBEDDED THUNDERSTORMS MAY LINGER INTO FRIDAY MORNING AS
A WEAK MID/UPPER-LEVEL SHORTWAVE CONTINUES TO MOVE EAST/NORTHEAST
ACROSS THE PANHANDLES. A WEAKENING/VEERING LOW-LEVEL JET INTO THE
MORNING HOURS MAY ALSO HELP TO SUSTAIN SOME CONVECTION. ADDITIONAL
THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE FRIDAY AFTERNOON AND
EVENING. FORCING FOR ASCENT LOOKS TO BE WEAKER THAN YESTERDAY AND
TODAY...WITH NO CONSIDERABLE SHORTWAVE TROUGHS EVIDENT ATTM. HOWEVER
A SOUTHWEST FLOW ALOFT DOWNSTREAM OF THE WEST COAST UPPER LOW WILL
MAINTAIN WEAK LEE SURFACE TROUGHING ACROSS EASTERN NM. WEAK SURFACE
CONVERGENCE NEAR THIS BOUNDARY ALONG WITH DIABATIC HEATING AND SOME
SUBTLE DIFFLUENCE ALOFT WILL LIKELY BE SUFFICIENT TO TRIGGER ISOLATED
TO SCATTERED CONVECTION DURING THE AFTERNOON AND EVENING HOURS.
SOUTHERLY LOW-LEVEL FLOW EAST OF THE LEE TROUGH WILL MAINTAIN RICH
LOW-LEVEL MOISTURE...CONTRIBUTING TO MODERATE INSTABILITY. DEEP LAYER
SHEAR LOOKS TO BE A BIT WEAKER THAN PREVIOUS DAYS /BULK SHEAR VALUES
AROUND 25 KTS/...BUT STILL SUFFICIENT IN COMBINATION WITH THE
ANTICIPATED INSTABILITY TO SUPPORT SOME STRONG TO POSSIBLY SEVERE
CONVECTION.

THUNDERSTORM CHANCES DROP OFF THIS WEEKEND AS THE UPPER RIDGE BUILDS
NORTH AND WEST OVER THE REGION. RESULTANT SUBSIDENCE WILL BEGIN TO
SUPPRESS RAIN CHANCES...AS THE MID-LEVEL MONSOON TAP IS ALSO SHUNTED
WEST OF THE AREA. WITH THE RIDGE STILL IN THE PROCESS OF BUILDING IN
SATURDAY AND THE MONSOON PLUME STILL NOT FULLY SHUNTED
WESTWARD...COULD SEE A COUPLE ISOLATED STORMS MAINLY ACROSS THE
SOUTHWEST TX PANHANDLE SATURDAY AFTERNOON.

HOT/DRY JULY CONDITIONS SHOULD THEN TAKE HOLD SUNDAY INTO EARLY NEXT
WEEK AS THE UPPER RIDGE BUILDS OVERHEAD. THE RIDGE MAY BE SUPPRESSED
ENOUGH BY TUESDAY AND WEDNESDAY TO ALLOW THUNDERSTORM CHANCES TO
CREEP BACK INTO THE NORTHERN PANHANDLES AS THE MONSOON TAP IS BENT
BACK INTO THESE AREAS.
