AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
741 PM CDT SUN APR 13 2014

.UPDATE...
BASED ON THE CURRENT RADAR TRENDS...REMOVED POP OVER THE FAR WEST
THE REST OF THE EVENING. LEFT IN SLIGHT AND CHANCE POP FOR OUR
NORTHERN MOST AREAS THE REST OF TONIGHT WITH CONTINUED MENTION OF
POSSIBLE SEVERE. WATCHING ONE LONE SEVERE STORM APPROACHING
COPPERAS COVE. ITS BEEN A RIGHT MOVER FOR SEVERAL HOURS AND MAY
CLIP PART OF THE NORTHERN EDGES OF BURNET...WILLIAMSON...AND/OR LEE
COUNTIES IF IT MAKES IT THAT FAR SOUTHEAST. STILL THE POSSIBILITY
OF REDEVELOPMENT LATER TONIGHT WITH THE APPROACHING COLD FRONT.
OVERALL CHANCES REMAIN LOW HOWEVER.

.PREV DISCUSSION... /ISSUED 631 PM CDT SUN APR 13 2014/

AVIATION...
/00Z TAFS/
MODERATE SOUTHERLY FLOW CONTINUES ACROSS THE REGION. DRY LINE
REMAINS WEST OF THE REGION AND SHOWERS AND THUNDERSTORMS HAVE
TRIED TO FIRE...BUT JUST CANNOT GET GOING DUE TO STRONG CAP.
STRONG COLD FRONT IS LOCATED ACROSS THE SOUTHERN PORTIONS OF THE
PANHANDLE. THE FRONT WILL MOVE SOUTH OVERNIGHT AND ARRIVE IN OUR
AREA 12Z-14Z. COULD SEE SOME SHOWERS AHEAD OF THE FRONT TONIGHT
AND EVEN BEHIND THE FRONT BUT LOOKING LESS LIKELY FOR THUNDER AT
THIS TIME. VFR CONDITIONS WILL BECOME MVFR 03Z-05Z THEN IFR 07Z-
08Z. AFTER COLD FRONT MOVES THROUGH 12Z-13Z CEILINGS WILL BECOME
MVFR THEN AFTER 18Z BACK TO VFR. SOUTHERLY WINDS AT 10 TO 15 KNOTS
AHEAD OF COLD FRONT. AFTER FROPA NORTHERLY WINDS WILL INCREASE TO
25-35 KNOTS WITH GUSTS TO NEAR 40 KNOTS. EXPECT WINDS TO DECREASE
AFTER 03Z TUESDAY TO NEAR 15 KNOTS.

PREV DISCUSSION... /ISSUED 343 PM CDT SUN APR 13 2014/

SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)...
RAPID THUNDERSTORM DEVELOPMENT HAS BEEN OCCURRING ALONG THE
DRYLINE AS IT'S BEEN PUSHING EASTWARD ACROSS WEST CENTRAL/NORTH
CENTRAL TEXAS THIS AFTERNOON. DUE TO THE RAPID INTENSIFICATION OF
STORMS ALONG THE DRYLINE...SPC HAS EXPANDED THE SLIGHT RISK AREA
FARTHER WEST/SOUTHWEST TO ACCOUNT FOR THE TAIL-END OF THE DRYLINE
ANTICIPATED TO REACH INTO VAL VERDE COUNTY BEFORE RETREATING
WESTWARD TONIGHT. THUNDERSTORMS WILL DECREASE IN INTENSITY THIS
EVENING WITH THE LOSS OF DAYTIME HEATING...BUT A FEW SHOWERS AND
THUNDERSTORMS COULD LINGER INTO THE OVERNIGHT HOURS ACROSS OUR FAR
NORTHEASTERN AREAS AS AN UPPER LEVEL SHORT-WAVE TROUGH MOVES INTO
EAST TEXAS.

DESPITE THE LULL IN ACTIVITY OVERNIGHT...A SECOND ROUND OF SHOWERS
AND THUNDERSTORMS IS EXPECTED MONDAY MORNING AHEAD OF THE COLD
FRONT. THE COLD FRONT IS EXPECTED TO REACH THE HILL COUNTRY AROUND
SUNRISE...THEN REACH THE SOUTHERN PORTIONS OF THE CWA BEFORE NOON.
THE POST-FRONTAL ENVIRONMENT APPEARS TO BE CONDUCIVE FOR AT LEAST
A CHANCE OF SHOWERS. OTHERWISE...CHANCES FOR RAIN WILL END FROM
NORTHWEST TO SOUTHEAST THROUGHOUT THE DAY.

BREEZY NORTH WINDS WILL SPREAD ACROSS THE REGION BEHIND THE FRONT.
A WIND ADVISORY WILL BE IN EFFECT FROM 7 AM UNTIL 7 PM MONDAY. THE
STRONG NORTHERLY WINDS AT THE SURFACE AND ALOFT WILL ALLOW A MUCH
DRIER AND COOLER AIRMASS TO FILTER INTO THE AREA DURING THE DAY ON
MONDAY. TEMPERATURES ARE EXPECTED TO REMAIN STEADY OR SLOWLY FALL
DURING THE AFTERNOON. WINDS WILL BEGIN TO DECREASE AND BECOME LESS
GUSTY MONDAY NIGHT.

LONG TERM (TUESDAY THROUGH SUNDAY)...
SURFACE HIGH PRESSURE WILL MOVE INTO THE REGION IN THE WAKE OF THE
FRONT. THE RIDGING AND NORTHERLY WINDS WILL ALLOW COOL AND DRY
AIR TO CONTINUE TO SPILL INTO THE REGION MONDAY NIGHT AND TUESDAY.
TEMPERATURES TUESDAY MORNING WILL BE MUCH COOLER THAN WE HAVE HAD
THE PAST SEVERAL DAYS. LOWS WILL FALL TO THE MID TO UPPER 30S
ACROSS MOST OF THE AREA...WITH PORTIONS OF THE HILL COUNTRY
FALLING INTO THE LOW 30S. THERE IS THE POTENTIAL FOR SPOTTY BRIEF
FREEZING TEMPERATURES ACROSS THE HILL COUNTRY TUESDAY MORNING. ANY
AREAS WHICH DO REACH FREEZING WILL WARM UP QUICKLY AFTER SUNRISE
UNDER CLEAR SKIES. TUESDAY AFTERNOON WILL BE SUNNY AND MILD AS
SURFACE HIGH PRESSURE AND LIGHT NORTHERLY WINDS PREVAIL. THE SFC
RIDGE WILL BEGIN TO SHIFT TO THE EAST ON TUESDAY...ALLOWING
ONSHORE FLOW TO RETURN TUESDAY NIGHT. DESPITE THE RETURN OF
SOUTHEASTERLY WINDS...MOISTURE RETURN WILL BE SLOW. CLEAR SKIES
AND LIGHT WINDS ARE EXPECTED TUESDAY NIGHT...BRINGING ANOTHER
CHILLY MORNING ON WEDNESDAY. WARM SOUTHERLY WINDS WILL ENABLE A
WARMING AND MOISTENING TREND THROUGH THE MIDDLE OF THE WEEK.

MODELS HAVE COME INTO A LITTLE BETTER AGREEMENT WITH THE UPPER
PATTERN DURING THE LATTER HALF OF THE WEEK...BUT THERE ARE STILL
INCONSISTENCIES AMONG THE MODELS AS WELL AS FROM RUN TO RUN. THE
OVERALL CONSENSUS SHOWS TROUGHING DEVELOPING TO OUR NORTHWEST
DEVELOPING MID-WEEK...ENHANCING THE MOISTURE ADVECTION ACROSS OUR
AREA. THE TROUGH WILL EVENTUALLY MOVE EAST ACROSS THE PLAINS
STATES AND SENDS A COLD FRONT INTO SOUTHERN TEXAS BY FRIDAY. THIS
SCENARIO WOULD LEAD TO A CHANCE FOR SHOWERS AND THUNDERSTORMS
MAINLY ACROSS EASTERN PORTIONS OF THE REGION WHERE MOISTURE DEPTH
IS GREATEST. MODELS HAVEN'T BEEN STELLAR SO FAR THIS SEASON WITH
FRONTAL SYSTEMS...SO SEVERAL CHANGES TO THE EXTENDED PERIOD ARE
EXPECTED.

FIRE WEATHER...
ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED
ACROSS AT LEAST A PORTION OF THE REGION EACH DAY THROUGH
WEDNESDAY. PLEASE SEE THE FIRE WEATHER DISCUSSION FWFEWX PRODUCT
FOR ADDITIONAL DETAILS.
