AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
301 AM CDT SAT AUG 1 2015

.SHORT TERM (TODAY THROUGH SUNDAY)...
CONVECTION FROM YESTERDAY AFTERNOON HAS ENDED ACROSS THE AREA AND
WE ARE ONLY LEFT WITH ANVIL DEBRIS. WINDS ARE LIGHT AND VARIABLE
AND TEMPERATURES ARE CURRENTLY IN THE MIDDLE 70S. AS HEATING
OCCURS THIS MORNING EAST WINDS JUST OFF THE SURFACE...AS SEEN ON
AREA VAD WIND PROFILES...WILL BE ABLE TO MIX DOWN TO THE SURFACE
AND THIS EASTERLY FLOW IS EXPECTED TO PREVAIL INTO TOMORROW. THE
AIRMASS TO OUR EAST IS MUCH DRIER WITH 60-65F DEWPOINTS IN PLACE.
THIS MEANS THAT DRY-AIR ADVECTION WILL BE IN PLACE ACROSS MUCH OF
THE AREA LIMITING THUNDERSTORM CHANCES. THE DRY AIR IS EVIDENT ON
FORECASTED CAPE FIELDS WITH ONLY SMALL VALUES OF INSTABILITY
REMAINING ACROSS THE WESTERN COUNTIES. PW VALUES IN THIS REGION
WILL REMAIN ABOVE 1.5 INCHES AS THE DRIEST AIR REMAINS EAST OF
THIS AREA. WILL CONTINUE 20-30 POPS THIS AFTERNOON FOR LOCATIONS
WEST OF AN EAGLE PASS TO KERRVILLE LINE. TEMPERATURES ARE
EXPECTED TO BE IN THE UPPER 90S TO 102 DEGREES AND ANY
THUNDERSTORMS THAT DO DEVELOP COULD PRODUCE GUSTY WINDS GIVEN
AMPLE DEWPOINT DEPRESSIONS. THE DRIER AIR WILL LIMIT THE POTENTIAL
FOR HIGHER HEAT INDICES THIS AFTERNOON ACROSS THE AREA.

DEWPOINTS IN THE 50S/60S WILL CONTINUE ON SUNDAY ONCE AGAIN
KEEPING HEAT INDEX VALUES BELOW 105 ACROSS THE AREA. HIGHS WILL
BE IN THE 96-102 DEGREE RANGE WITH THE COOLER TEMPERATURES ACROSS
THE NORTHERN HILL COUNTRY AND THE WARMER TEMPERATURES CLOSER TO
THE RIO GRANDE. THE ATMOSPHERE WILL BE TOO DRY ACROSS OUR ENTIRE
CWA FOR ANY RAIN CHANCES ON SUNDAY.

&&

.LONG TERM (SUNDAY NIGHT THROUGH FRIDAY)...
THE EXTENDED FORECAST LOOKS TO BE RATHER QUIET AS HIGH PRESSURE
RE-ANCHORS TO OUR WEST AND BUILDS IN STRENGTH THROUGH THE WORK-
WEEK. SOUTHERLY FLOW WILL SLOWLY INCREASE SURFACE DEWPOINTS
THROUGH MID-WEEK AND WE SHOULD SEE THE HEAT INDICES SLOWLY CLIMB
AS WELL. THURSDAY LOOKS TO BE THE HOTTEST DAY AS 850 TEMPS WARM
ABOVE 25C ACROSS MUCH OF THE AREA. THIS SHOULD EQUATE TO HIGH
TEMPERATURES NEAR OR ABOVE 100 DEGREES FOR MUCH OF THE AREA
EXCLUDING THE NORTHERN HILL COUNTRY. AFTERNOON DEWPOINTS IN THE
MIDDLE 60S WILL ALLOW HEAT INDEX VALUES TO BE ABOVE 105 FOR MUCH
OF THE AREA. THE LONG TERM PORTION OF THE FORECAST WILL REMAIN
RAIN FREE.
