AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
614 PM CST TUE MAR 8 2016

.AVIATION.../OOZ TAFS
VFR CIGS SHOULD CONTINUE FOR THE NEXT FEW HOURS AT ALL TAF SITES
AS TSRA REMAINS FOCUSED ALONG A STATIONARY FRONTAL BOUNDARY TO
THE NORTHWEST FROM JCT TO AQO TO JUST SOUTH OF ACT. SHRA AND ISO
TSRA ARE EXPECTED TO DEVELOP SOUTHWEST OF SAT/SSF AS WELL OVER
THE NEXT FEW HOURS. TSRA AND MVFR CIGS SHOULD STAY OUT OF THE I-35
TAF SITES UNTIL 5-6Z IF CURRENT RADAR AND HI-RES MODEL TRENDS HOLD
AND CONTINUE THROUGH ABOUT 10-11Z. SHRA SHOULD END FROM WEST TO
EAST BETWEEN 12-14Z AS WINDS BECOME NORTHERLY BEHIND A WEAK FRONT
AT THE I-35 TAF SITES. LESS CONFIDENT THAT TSRA WILL OCCUR AT DRT
TONIGHT...SO HAVE JUST INCLUDED TEMPO TSRA THERE FROM 4-8Z.

.MESOSCALE UPDATE...
AS ISOLATED AFTERNOON CONVECTION PROGRESSES OUT NORTH OUT OF OUR
CWA...MORE DEVELOPMENT IS BEING OBSERVED ON SATELLITE AND RADAR
FURTHER WEST IN THE BIG BEND AND WESTERN VAL VERDE COUNTY AREA.
UPPER LEVEL ENERGY IS BEGINNING TO SPREAD INTO WEST TEXAS AND THE
WESTERN EDWARDS PLATEAU WHICH WILL CONTINUE THROUGHOUT THE EVENING
AND OVERNIGHT HOURS. AT THE SURFACE...A QUASI STATIONARY FRONTAL
BOUNDARY IS SLOWLY SAGGING SOUTH INTO NORTHERN BURNET COUNTY AS
WELL AS A DRY LINE POSITIONED ALONG A LINE FROM JUST EAST OF
SONORA...TO JUST WEST OF ROCKSPRINGS...TO CARRIZO SPRINGS. A
THUNDERSTORM HAS DEVELOPED ALONG THE DRY LINE IN SOUTHERN DIMMIT
COUNTY...WITH ADDITIONAL STORMS EXPECTED TO DEVELOP IN THE NEXT
FEW HOURS.

JUST EAST OF THE DRY LINE...ALONG THE EASTERN PERIPHERY OF THE
ESCARPMENT...A SIGNIFICANT INSTABILITY AXIS IS SET UP ALL THE WAY TO
THE AFOREMENTIONED NORTHERN BOUNDARY. AS FURTHER UPPER LEVEL SUPPORT
SPREADS IN FROM THE EAST...THIS COULD BE THE AREA OF BEST
POTENTIAL FOR SEVERE STORM DEVELOPMENT. LARGE HAIL AND DAMAGING
STRAIGHT LINE WINDS ARE STILL THE MAIN THREATS GIVEN THE
INSTABILITY AND LAPSE RATES ON FORECAST SOUNDINGS...BUT TORNADIC
POTENTIAL IS STILL POSSIBLE AS LOW LEVEL HELICITY VALUES ARE
EXPECTED TO INCREASE THROUGH 03Z TONIGHT. TORNADIC POTENTIAL
SHOULD INCREASE AS STORMS MOVE EAST TOWARDS THE I-35 CORRIDOR INTO
AN AREA WITH LOWER LCLS AND A STRENGTHENING SOUTHERLY LOW LEVEL
JET LATER TONIGHT.

&&

.PREV DISCUSSION... /ISSUED 357 PM CST TUE MAR 8 2016/

SHORT TERM (TONIGHT THROUGH WEDNESDAY NIGHT)...
CONVECTION FROM EARLIER THIS MORNING HAS MOVED INTO NORTH TEXAS.
IN THE WAKE OF THE CONVECTION...SKIES HAVE PARTIALLY CLEARED AND
DAYTIME HEATING HAS HELPED TO INITIATE A NEW ROUND OF CONVECTION
ACROSS THE RIO GRANDE PLAINS. ADDITIONAL STORM DEVELOPMENT IS
EXPECTED ACROSS THE SOUTHERN EDWARDS PLATEAU AS A WEAK BOUNDARY IS
CURRENTLY LOCATED ACROSS NORTHERN EDWARDS COUNTY BACK INTO
PORTIONS OF CENTRAL TEXAS NEAR NORTHWEST LLANO COUNTY. ANY STORMS
NEAR THE RIO GRANDE THROUGH THIS EVENING WILL REMAIN HIGH-BASED
GIVEN TEMP/DEW POINT SPREADS OF 40 DEGREES OR MORE AS OF LATE
AFTERNOON. THE PRIMARY CONCERN WITH THIS ACTIVITY WILL BE HAIL AND
DAMAGING WINDS. AS THE EVENING PROGRESSES...ADDITIONAL
THUNDERSTORM DEVELOPMENT IS EXPECTED ACROSS ALL OF SOUTH CENTRAL
TEXAS AS STRONG UPPER LIFT SPREADS IN FROM THE WEST. WHILE THE
MAIN CONCERN IS EXPECTED TO BE DAMAGING THUNDERSTORM WINDS...
CAN/T RULE OUT A FEW TORNADOES GIVEN FAVORABLE WINDS IN THE LOWEST
FEW KM OF THE ATMOSPHERE. BY EARLY WEDNESDAY MORNING...WE SHOULD
START TO SEE SEVERE CONCERNS DECREASE...BUT WILL CERTAINLY NEED TO
MONITOR FOR LOCALLY HEAVY RAINFALL. RAINFALL AMOUNTS THROUGH
WEDNESDAY AFTERNOON SHOULD RANGE FROM 3/4" ALONG THE RIO GRANDE...
AROUND 2" ALONG THE I-35 CORRIDOR AND NEAR 3.5" INCHES ALONG
HIGHWAY 77. SOME LOCALLY HEAVIER POCKETS OF RAINFALL COULD PUSH
RAINFALL TOTALS UP TO 5 INCHES IN A FEW SPOTS.

MOST AREAS SHOULD SEE A BREAK IN THE WEATHER WEDNESDAY AFTERNOON.
DURING THE EVENING AND OVERNIGHT HOURS...THE SHORT RANGE MODELS
ARE SHOWING ADDITIONAL CONVECTION COULD MOVE INTO AREAS EAST OF
I-35...WITH CURRENT EMPHASIS ON THE COASTAL PLAINS AND HIGHWAY 77
CORRIDOR WHERE A BOUNDARY IS EXPECTED TO DEVELOP. WE/LL NEED TO
MONITOR THIS AREA CAREFULLY FOR THE POTENTIAL FOR LOCALLY HEAVY
RAINFALL.

LONG TERM (THURSDAY THROUGH TUESDAY)...
THE UPPER LOW CONTINUES TO REMAIN THE DOMINANT WEATHER FEATURE
THROUGH THE END OF THE WORK WEEK. IF CURRENT MODELS ARE CORRECT...
THE ABOVE MENTIONED BOUNDARY WILL DRIFT NORTHWARD AS A WARM FRONT
THURSDAY AFTERNOON. ADDITIONAL LIFT WOULD LEAD TO ANOTHER GOOD
CHANCE OF RAIN ACROSS SOUTH CENTRAL TEXAS AND WE HAVE INCREASED
RAIN CHANCES ON THURSDAY INTO EARLY FRIDAY. THE UPPER LOW IS THEN
EXPECTED TO GRADUALLY WEAKEN AND LIFT NORTHWARD INTO EAST TEXAS ON
SATURDAY. RAIN CHANCES WILL DECREASE FROM WEST TO EAST FRIDAY
NIGHT INTO SATURDAY...WITH RAIN CHANCES ONLY IN THE 20-30% RANGE.
ANOTHER UPPER LEVEL LOW MOVES ACROSS NORTH TEXAS ON SUNDAY... BUT
WE DO NOT EXPECT PRECIPITATION WITH THIS UPPER LOW ACROSS SOUTH
CENTRAL TEXAS. DRY AND WARM WEATHER IS ANTICIPATED EARLY NEXT
WEEK...WITH HIGHS WELL INTO THE 80S AND EVEN SOME LOWER 90S ON
MONDAY.
