.PREV DISCUSSION... /ISSUED 429 PM CDT FRI SEP 19 2014/

DISCUSSION...TONIGHT THROUGH THURSDAY

THE FIRST FEW PERIODS OF THE FORECAST REMAIN THOSE OF MOST
INTEREST...BUT RAIN CHANCES CERTAINLY WON`T LEAVE THE PANHANDLES AS
WE MOVE INTO NEXT WEEK.

THIS AFTERNOON AND TONIGHT...
HEAVY RAIN WILL CONTINUE TO BE POSSIBLE...MAINLY IN THE SW TX
PANHANDLE THIS AFTERNOON AND EVENING. SYNOPTIC FORCING FOR ASCENT IS
PRETTY MINIMAL...BUT PRECIP EFFICIENCY IS PEGGED AT ABOUT THE MAX
FOR THE AREA GIVEN THE TROPICAL NATURE. WHAT WOULD SEEMINGLY BE
LIGHT TO MODERATE SHOWERS ON RADAR ARE SPITTING OUT A HALF INCH OF
RAIN IN 20 MINUTE INTERVALS AS THEY PASS. HAVE THEREFORE LEFT THE
FLASH FLOOD WATCH FOR A PORTION OF THE SW TX PANHANDLE, WHERE THE
SHOWERS ARE MOST WIDESPREAD THIS AFTERNOON. THINK THAT THE LATE
AFTERNOON/EVENING TIME FRAME IS WHEN WE WILL SEE MOST OF OUR RAIN
FROM THIS EVENT. THINK ANY FLASH FLOODING WILL BE PRETTY LOCALIZED.

SATURDAY THROUGH THURSDAY...
RAIN CHANCES WILL CONTINUE THROUGH THIS PERIOD AS MOISTURE REMAINS
DEEP AND PLENTIFUL. A GENERAL LACK OF FORCING MEANS AFTERNOON HOURS
SHOULD BE SLIGHTLY MORE FAVORED THAN OTHERS...THOUGH THE WEEK WILL
BE NO MEANS BE A WASHOUT. TEMPERATURES SHOULD BE NEAR OR BELOW
SEASONAL AVERAGES FOR MOST OF THE WEEK AS CLOUD COVER WILL BE QUITE
NOTICEABLE.
