AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
1222 AM CDT SAT OCT 11 2014

.AVIATION...
LITTLE CHANGE WAS MADE TO THE 06Z TAF PACKAGE FROM THE 00Z TAF
PACKAGE. HIGH RESOLUTION MODELS STILL HAVE THE FRONT MOVING
THROUGH CENTRAL TEXAS BETWEEN 10Z AND 15Z SATURDAY MORNING WITH A
NORTHERLY WIND SHIFT ALONG WITH SHOWERS AND THUNDERSTORMS. HAVE
REPLACED THE PROB30 GROUP WITH PREVAILING TSRA AT THE I-35
TERMINALS AND CHANGED THE VCSH TO A TSRA AT DRT GIVEN THE ISOLATED
THUNDERSTORM ACTIVITY ALREADY ONGOING IN VAL VERDE COUNTY. AT THIS
HOUR THUNDERSTORMS STRETCH FROM SAN ANGELO NORTHWEST THROUGH THE
DFW AREA. THIS COMPLEX OF STORMS WILL BEGIN ITS TREK SOUTH IN THE
EARLY MORNING HOURS. AHEAD OF IT MVFR CIGS HAVE ALREADY COME IN AT
SAT AND SSF AND WILL FILL IN BY 06Z ALONG I-35...BUT HOLD OFF UNTIL
07Z AT DRT.

ONCE THE FRONT MOVES THROUGH TOMORROW MORNING NORTH WINDS 5-10
KNOTS ARE EXPECTED WITH CIGS RISING AND TO VFR BY 19Z.

.PREV DISCUSSION... /ISSUED 1007 PM CDT FRI OCT 10 2014/

UPDATE...
THE EVENING TRENDS INDICATE A SLOWER ARRIVAL OF RAIN CHANCES FOR
THE I-35 CORRIDOR AND SLIGHTLY HIGHER POPS FOR LATE THIS EVENING
THROUGH SATURDAY MORNING FOR WESTERN AREAS NORTH OF HIGHWAY 90. AS
PREVIOUS FORECASTERS HAVE DEPICTED...IMPACTS SHOULD BE SIMILAR...
WITH A MARGINAL SEVERE POTENTIAL OVER NORTHERN COUNTIES FOR A FEW
MORE HOURS AND AN OVERNIGHT HEAVY RAINFALL POTENTIAL OF 1-2 INCHES
ACROSS MAINLY THE EASTERN HILL COUNTRY AND PARTS OF CENTRAL TX.
DEVELOPING COMPLEX OVER WEST CENTRAL TX SHOULD BE IN THE WEAKENING
PHASE WITH MINIMAL LIGHTING EXPECTED ALONG THE HIGHER POPULATION
AREAS OF THE I-35 CORRIDOR BY DAYBREAK. HOWEVER...RAIN CHANCES
WILL REMAIN GOOD THROUGH 18Z SATURDAY...AND WILL FOLLOW HIGHER RES
MODEL SUGGESTIONS THAT POPS SHOULD BE HIGHER FROM 12Z TO 18Z.

PREV DISCUSSION... /ISSUED 624 PM CDT FRI OCT 10 2014/

AVIATION...
VFR CONDITIONS WILL CONTINUE INTO THE OVERNIGHT HOURS. WINDS THIS
EVENING WILL BE OUT OF THE SOUTH AT 10-15 KNOTS. MVFR STRATUS WILL
DEVELOP ONCE AGAIN THIS EVENING BY 08Z AT ALL TERMINALS.

THE INCOMING COLD FRONT IS CURRENTLY ACROSS NORTHEAST TEXAS FROM
LUBBOCK TO THE RED RIVER. IT WILL PUSH SOUTH OVERNIGHT. CURRENT
THINKING IS THAT SHOWERS AND THUNDERSTORMS WILL BE ONGOING ALONG
AND AHEAD OF THE FRONT. THESE WILL IMPACT THE AUSTIN AREA FIRST
BETWEEN 10Z AND 14Z...THEN PUSH THROUGH SAN ANTONIO BETWEEN 11Z
AND 15Z. HAVE HANDLED THIS WITH A PROB30 FOR NOW. SHOWERS WILL BE
POSSIBLE AT DRT BETWEEN 08Z AND 13Z.

THE WINDS BEHIND THE FRONT WILL SHIFT AROUND TO THE NORTH. BASED
ON A CONSENSUS OF THE HIGH RESOLUTION MODELS THE WIND SHIFT WILL
MOVE THROUGH DRT AROUND 11Z...AUS AROUND 12Z...SAT/SSF AROUND 13Z.
WIND SPEEDS BEHIND THE FRONT WILL BE IN THE 5-10 KNOT RANGE WITH
NORTH WINDS CONTINUING THROUGH THE DAY SATURDAY.

PRECIPITATION WILL END AND VFR CONDITIONS WILL BREAK OUT BY 19Z
SATURDAY ACROSS SOUTH CENTRAL TEXAS.

SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)...
UPPER AIR ANALYSIS THIS MORNING SHOWED THE RIDGE OVER THE SOUTHERN
PLAINS BREAKING DOWN AS A TROUGH DIGS THROUGH THE SOUTHWEST. AT
THE SURFACE...SOUTHERLY FLOW DOMINATES ACROSS SOUTH TEXAS KEEPING
MOIST AIR IN PLACE. DEW POINTS ARE GENERALLY IN THE UPPER 60S. A
FRONTAL BOUNDARY STRETCHES FROM NEAR OKLAHOMA CITY TO MIDLAND. THE FRONT
WILL BE THE FOCUS OF OUR WEATHER IN THIS PERIOD. MODELS ARE
SHOWING THE FRONT MOVING THROUGH OUR CWA STARTING LATE TONIGHT AND
EXITING OUR SOUTHERN BOUNDARY BY NOON SATURDAY. THIS WILL BRING A
CHANCE FOR SHOWERS AND THUNDERSTORMS SPREADING FROM NORTH TO SOUTH
FROM AROUND MIDNIGHT TO NOON. FORECAST SOUNDINGS SUGGEST MARGINAL
CAPE WITH WEAK VERTICAL WIND SHEAR SO SOME STRONG THUNDERSTORMS
WILL BE POSSIBLE. THE MOST LIKELY AREA FOR STRONG STORMS WILL BE
NORTHEAST OF A LINE FROM FREDERICKSBURG TO HALLETTSVILLE. WIND
GUSTS TO 50 MPH ARE THE MAIN THREAT. MODELS ARE ALSO SHOWING A
SMALL AREA...FROM LLANO TO LEE COUNTIES...OF PW ABOVE 1.75 INCHES
FOR A SHORT PERIOD WITH THE FRONTAL PASSAGE. THIS MAY PRODUCE SOME
LOCALLY HEAVY RAINFALL UP TO TWO INCHES. SOME SHOWERS MAY LINGER
BEHIND THE FRONT AS COOLER AIR MOVES IN. SURFACE FLOW WILL BEGIN
TO SWITCH BACK TO SOUTHERLY SATURDAY NIGHT.
