Area forecast discussion, May 8, 12:48 PM CDT, 1 hour 32 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
1248 PM CDT THU MAY 8 2014

.UPDATE...
PLEASE SEE THE 18Z AVIATION DISCUSSION BELOW.

&&

.AVIATION...
CIGS ARE SLOWLY LIFTING AS DAYTIME HEATING AND MIXING COMMENCE.
THE HEATING IS ALSO AIDING IN CONVECTION AND THE LATEST RADAR DATA
SHOWS AN INCREASE IN COVERAGE ALONG THE I-35 CORRIDOR. WE/LL
CONTINUE TO MENTION TEMPO GROUPS FOR SHRA/TSRA THROUGH THIS
AFTERNOON FOR THE I-35 TAF SITES. WITH THE LOSS OF DAYTIME
HEATING... A DECREASE IN CONVECTION IS EXPECTED AND WE/LL KEEP THE
FORECAST PRECIPITATION FREE AFTER 02Z. CIGS WILL QUICKLY LOWER
THIS EVENING WITH IFR CONDITIONS EXPECTED AROUND 06Z. OUT WEST AT
KDRT... WE/LL KEEP THE FORECAST DRY WITH VFR CONDITIONS AS MOST
CONVECTION SHOULD REMAIN EAST OF THE TERMINAL. CIGS SHOULD MOVE
BACK IN DURING THE EARLY MORNING HOURS ON FRIDAY AND WILL START
MVFR CIGS AROUND 09/09Z.

&&

.PREV DISCUSSION... /ISSUED 1057 AM CDT THU MAY 8 2014/

UPDATE...
MINOR ADJUSTMENTS TO FIRST PERIOD.

DISCUSSION...
CONVECTIVE ACTIVITY HAS WANED OVER THE LAST FEW HOURS...BUT WILL
RE-INITIATE THIS AFTERNOON AS THE SFC DRYLINE AND UPPER TROUGH
BOTH CONTINUE TO PUSH EASTWARD. PARTIAL CLEARING IS EXPECTED AHEAD
OF THE DRYLINE...WHICH WILL ALLOW SFC TEMPS TO WARM UP AND FURTHER
DESTABILIZE THE ENVIRONMENT. FORCING ALONG THE DRYLINE AND STEEP LAPSE
RATES APPEAR TO BE STRONG ENOUGH FOR SOME OF THE STORMS THIS AFTERNOON
AND EVENING TO BECOME STRONG TO SEVERE. LARGE HAIL AND DAMAGING
WINDS ARE THE MAIN CONCERNS. HOWEVER...CLOUD COVER WILL LINGER
THROUGHOUT THE DAY ACROSS EASTERN PORTIONS OF THE REGION AND COULD
THEREFORE LIMIT THE POTENTIAL FOR STORMS TO BECOME AND/OR MAINTAIN
SEVERE LEVELS. ADDITIONALLY...MORNING SOUNDINGS INDICATE PWS RANGE
FROM 1.5 TO OVER 2 INCHES ACROSS MUCH OF THE CWA...SO THERE IS THE
POTENTIAL FOR LOCALLY HEAVY RAIN (GENERALLY ALONG AND SOUTHEAST OF
THE I-35 CORRIDOR WHERE THE HIGHER PWS RESIDE). DUE TO THE ONGOING
DROUGHT THE HEAVY RAINS WOULD BE A WELCOME SIGHT...BUT THE CONCERN
LIES WITH THE INTENSITY OF THE RAINFALL RESULTING IN QUICK RUNOFF.
ONGOING FORECAST IS GENERALLY ON TRACK WITH ONLY MINOR ADJUSTMENTS
MADE TO THE FIRST PERIOD FOR CURRENT TRENDS.

PREV DISCUSSION... /ISSUED 628 AM CDT THU MAY 8 2014/

AVIATION...
RAIN SHIELD JUST CLIPPING THE SOUTHEAST EDGE OF THE AREA THIS
MORNING...WITH LIGHT PRECIP FALLING HERE AT KHYI. RAINFALL VC KSSF
AND SHOULD MOVE INTO KAUS VC WITHIN THE HOUR. ADDED TEMPO GROUPING
FOR THOSE SITES FOR -RA...BUT MINIMAL VIS RESTRICTIONS.BREEZY
CONDITIONS KICK IN THIS MORNING WITH SE 15G25KTS ALONG THE HILL
COUNTRY...WHILE LIGHTER WINDS TO THE WEST. SHOWERS AND
THUNDERSTORMS STILL A GOOD POSSIBILITY FOR THE HILL COUNTRY
TODAY...SO CONTINUING WITH TEMPO TSRA GROUPINGS. CIGS REACH VFR
THIS AFTERNOON...BUT REMAIN BKN TO OVC. WINDS GO L/V OVERNIGHT ALL
AREAS...WITH CIGS FALLING TO IFR BY MIDNIGHT.

PREV DISCUSSION... /ISSUED 350 AM CDT THU MAY 8 2014/

SHORT TERM (TODAY THROUGH FRIDAY)...
AN UPPER LEVEL TROUGH MOVES OUT ACROSS THE PLAINS TODAY DRAGGING
THE DRYLINE INTO WESTERN PARTS OF SOUTH CENTRAL TEXAS. UPWARD
FORCING INTERACTING WITH A MOIST AIRMASS (PWS AROUND 1.5 INCHES)
WILL GENERATE SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS EAST
OF THE DRYLINE. INSTABILITY AND SOME SHEAR MAY ALLOW FOR A FEW
STRONG TO SEVERE THUNDERSTORMS THIS AFTERNOON. HOWEVER...EXTENSIVE
CLOUD COVER MAY LIMIT THE STORM SEVERITY. SOME TRAINING OF THE
RAINS MAY CAUSE HEAVIER RAINS WHICH DUE TO DROUGHT CAUSED HARD
SOILS MAY CAUSE SOME RUNOFF ISSUES...ESPECIALLY IN URBAN AREAS.
MOST OF THE UPPER TROUGH MOVES OFF TO THE EAST WITH RAINS SLOWLY
ENDING. ALTHOUGH...A SMALL PIECE OF THE TROUGH BREAKS OFF AND
MOVES ACROSS SOUTHERN TEXAS ON FRIDAY CAUSING SOME SHOWERS AND
THUNDERSTORMS TO LINGER TONIGHT INTO FRIDAY EVENING. TROUGH AXIS
PASSES BY AT PEAK HEATING AND SOME STRONGER STORMS MAY BE POSSIBLE
AT THAT TIME IF THE DRYLINE LINGERS OVER THE HILL COUNTRY. CLOUD
COVER WILL KEEP TEMPERATURES NEAR OR SLIGHTLY COOLER THAN AVERAGE
IN THE EAST WHILE FAIR SKIES ALLOW FOR WELL ABOVE AVERAGE OUT WEST
TODAY AND FRIDAY.

LONG TERM (FRIDAY NIGHT THROUGH WEDNESDAY)...
ZONAL FLOW KEEPS THE WEEKEND RAIN FREE. EXCEPT SOME THUNDERSTORMS
OVER THE SERRANIAS DEL BURRO MAY CROSS THE RIO GRANDE VALLEY
SUNDAY EVENING. ANOTHER UPPER LEVEL TROUGH MOVES ACROSS THE PLAINS
EARLY NEXT WEEK SENDING A COLD FRONT THROUGH SOUTH CENTRAL TEXAS
LATER ON MONDAY INTO MONDAY EVENING. WILL MAINTAIN LOW CHANCES OF
SHOWERS AND THUNDERSTORMS FOR MONDAY INTO MONDAY NIGHT...THEN
ENDING ON TUESDAY AS THE TROUGH MOVES OFF TO THE EAST AND DRIER
AIRMASS MOVES INTO THE AREA. ABOVE AVERAGE TEMPERATURES OVER THE
WEEKEND TURN WELL BELOW AVERAGE BY THE MIDDLE OF NEXT WEEK.

FIRE WEATHER...
ELEVATED FIRE WEATHER CONDITIONS ARE EXPECTED WEST OF THE DRYLINE
THIS AFTERNOON ACROSS VAL VERDE COUNTY INTO WESTERN EDWARDS COUNTY
DUE TO HUMIDITIES IN THE TEENS AND WESTERLY WINDS UP TO 10 MPH.
ELEVATED FIRE WEATHER CONDITIONS RETURN TO THE VAL VERDE COUNTY
AREA TUESDAY AND WEDNESDAY AFTERNOONS DUE TO HUMIDITIES IN THE
UPPER TEENS AND WINDS AROUND 10 MPH.
