AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
330 PM CDT MON AUG 8 2005

.SHORT TERM...
WATER VAPOR IMAGERY CONTINUES TO ILLUSTRATE A SWATH OF MID-UPR LEVEL
DRYING LOCATED OVER MUCH OF THE FORECAST AREA AND POINTS UPSTREAM TO
THE NORTH AND NORTHWEST.  A LINE OF SCATTERED CONVECTION CONTINUES
TO DEVELOP AS CONDITIONAL INSTABILITY WITHIN THE AFOREMENTIONED AREA
REMAINS PRIME FOR DIURNAL CONVECTIVE DEVELOPMENT.  OTHERWISE...
IMPRESSIVE AND LONG-LIVED COMPLEX OF HEAVY RAIN PRODUCING
THUNDERSTORMS HAS ERODED OVER THE EAST AND SOUTHEAST FORECAST AREA
BETWEEN 1 AND 2 PM.  88D ESTIMATES AS HIGH AS 10 INCHES IN PORTIONS
OF STONEWALL COUNTY WITH 4 TO 6 INCHES ACROSS OTHER ISOLATED AREAS.
MAIN CONCERN WILL BE THIS EVENING/EARLY TONIGHT WITH LIGHT STEERING
CURRENTS ALOFT AND THE POTENTIAL FOR HEAVY RAINFALL ACROSS THE
NORTHWEST/WESTERN SECTIONS OF THE FORECAST AREA.  THESE CELLS APPEAR
TO BE MORE OF THE DIURNAL/PULSE VARIETY...HOWEVER INVERTED-V HINT OF
THE 12Z AND MODEL THERMODYNAMIC PROFILES SUGGEST BRIEF GUSTY WINDS
POSSIBLE WITH A FEW OF THESE STORMS...SIMILAR TO THE 54 MPH WIND
GUSTS EXPERIENCED AT BOTH HART AND DIMMITT SUNDAY EVENING BETWEEN 6
AND 7 PM.  LINGERING MID-LEVEL TROF AXIS AND SUBTLE SHORTWAVE ENERGY
WILL CONTINUE TO IMPACT THE AREA LATE TONIGHT AND TOMORROW...
FOLLOWING THE DIURNAL DECAY OF ONGOING CONVECTION OUT WEST.  BML.10

.LONG TERM...
SHWTV TROF SHOULD BE SE OF THE AREA BY TUE EVE AND UPR RIDGE WILL BE
BUILDING IN FROM THE WEST. DESPITE RISING HEIGHTS/THICKNESS UNDER
THE UPR RIDGE...WILL BE FAIRLY CONSERVATIVE WITH THE WARMUP GIVEN
OUR WET SOILS/MATURING COTTON ACROSS MUCH OF THE CWA. LATEST GFS RUN
SEEMS TO HAVE DE-EMPHASIZED THE LINGERING TROF ACROSS
CENTRAL/EASTERN TX AND OF MORE INTEREST IS THE UPR RIDGE FLATTENING
ACROSS THE CENTRAL ROCKIES/PLAINS AS WESTERLY FLOW INCREASES DUE TO
SEVERAL SHTWVS DROPPING SE OUT OF WEST CANADA. THIS HAS SUPPORT FROM
THE 0Z ECMWF. ALTHOUGH THE ATMOSPHERE TENDS TO DRY OUT ABOUT ABOVE
700 MB OR SO...CANT RULE OUT ISOLD AFTN AND EVE TSTMS WED-THU DUE TO
RESIDUAL MOISTURE AND DIURNAL HEATING. RIDGING WILL GRADUALLY BE
REPLACED BY TROFFING AND SW FLOW ALOFT BY NEXT WEEKEND. THIS WILL
BRING INCREASING MID-LVL MOISTURE IN FROM THE SW THUS TSTM CHANCES
SHOULD BE ON THE RISE ACROSS THE SRN ROCKIES AND POSSIBLY INTO OUR
WESTERN COUNTIES. ANOTHER CONCERN IS THE POSSIBILITY OF A COLD FRONT
THAT MAY MAKE A RUN FOR THE SPLNS ON WED BUT MOST LIKELY WILL HANG
UP UNTIL A STRONG SHTWV TROF MOVING ACROSS THE NRN PLAINS BRINGS IT
BACK SOUTH SAT OR SUN. THIS MAY BRING US COOLER TEMPERATURES AND A
BETTER CHANCE FOR RAIN. HAVE TRENDED POPS UP AND TEMPS DOWN JUST
SLIGHTLY FOR SUN AND MON AWAITING FURTHER DETAILS.

AVAILABLE...AND THIS COMBINED WITH THE EXPECTED SLOW-MOVING NATURE
OF THE THUNDERSTORMS SHOULD RESULT IN SOME LOCALLY HEAVY RAINFALL.
IN ADDITION INCREASED INSTABILITY LATE THIS AFTERNOON AND EARLY THIS
EVENING MAY ALLOW FOR SOME THUNDERSTORMS TO BECOME STRONG WITH
DOWNBURST WINDS AND SMALL HAIL POSSIBLE. HOWEVER NO SEVERE WEATHER
IS EXPECTED AT THIS TIME.

.DAYS TWO THROUGH SEVEN...

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.
