AREAS ON THE SOUTH SIDE OF LUBBOCK GENERALLY ALONG AND SOUTH OF 82ND

AREA FORECAST DISCUSSION

709 PM CDT SAT AUG 13 2005

.UPDATE...
FRONTAL BOUNDARY CONTINUES TO SLOWLY DRIFT SOUTHWARD INTO THE
NORTHERN CWA. MIDDLE LEVEL FLOW IS PARALLEL TO THIS BOUNDARY SO
TRAINING OF ECHOES IS A GOOD POSSIBILITY. PRECIPITABLE WATER
VALUES ARE ABOUT 175 PERCENT OF NORMAL SO WE KNOW THAT HEAVY
RAINFALL WILL BE POSSIBLE WITH THE THUNDERSTORMS THAT DEVELOP. WE
HAVE ALREADY SEEN RAINFALL RATES OVER 2 INCHES PER HOUR...MAYBE
EVEN HIGHER. HEAVY RAINS OVER THE LAST COUPLE DAYS HAVE SOAKED THE
SOILS OVER PORTIONS OF THE NORTHERN ZONES SO ANY ADDITIONAL
RAINFALL WILL LEAD TO RAPID RUN OFF. FOR THESE REASONS WE HAVE
DECIDED TO GO WITH A FLASH FLOOD WATCH OVER THE NORTHERN HALF OF
OUR CWA.

ADDITIONAL OUTFLOW BOUNDARIES SHOULD BRING A AT LEAST SCATTERED
THUNDERSTORMS TO THE THE SOUTHERN HALF OF THE CWA. WE WILL HAVE TO
WATCH THE FRONTAL BOUNDARY TO SEE IF IT CAN SAG A BIT FURTHER
SOUTH AND INTERACTS WITH THE LOW LEVEL JET OVERNIGHT. IF THE
OUTFLOW BOUNDARIES CAN FOCUS ANY OF THE THUNDERSTORMS FURTHER
SOUTH WE MAY NEED TO EXPAND THE FLASH FLOOD WATCH.

HAVE RAISED RAIN CHANCES AND QPF VALUES OVER THE NORTHERN CWA.

...LOCALLY HEAVY RAINFALL POSSIBLE TONIGHT AND SUNDAY...

SHOWERS AND THUNDERSTORMS WILL BECOME MORE NUMEROUS TONIGHT AND
SUNDAY ACROSS THE SOUTH PLAINS AND LOW ROLLING PLAINS. A COLD FRONT
NOSING INTO THE EXTREME SOUTHWEST TEXAS PANHANDLE EARLY THIS

BOUNDARIES...AND UPPER LEVEL DISTURBANCES WILL COMBINE TO PRODUCE
PERIODS OF LOCALLY HEAVY RAINFALL. WITH A WEAK FLOW ALOFT
THUNDERSTORMS DEVELOPING ALONG THE FRONT ARE EXPECTED TO MOVE VERY
SLOWLY AND INCREASE THE POTENTIAL FOR LOCALIZED FLOODING.
