Area forecast discussion, Mar 8, 11:41 PM CST, 4 hours 19 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 1141 PM CST THU MAR 8 2012 .DISCUSSION... SEE AVIATION FOR 06Z TAFS. && .AVIATION... MVFR CIGS AND NORTH WINDS AT 15 TO 25 KNOTS WILL CONTINUE TONIGHT...ALONG WITH OCNL RAIN AND SHRA. CIGS OF 1 THSD TO 2 THSD FT OVC ARE EXPECTED WITH VSBYS OCNLLY 5 TO 6 MILES IN LIGHT RAIN. ON FRIDAY CIGS OF 1 THSD TO 2 THSD FT OVC ARE EXPECTED TO BECOME CIGS 700 TO 1000 FEET FRIDAY NIGHT. OCNL RAIN WILL CONTINUE FRIDAY AND FRIDAY NIGHT. VSBYS ON FRIDAY NIGHT WILL BE AROUND 4 TO 6 MILES IN OCNL RAIN AND SHRA. && .PREV DISCUSSION... /ISSUED 940 PM CST THU MAR 8 2012/ UPDATE... MINOR ADJUSTMENTS TO LOW TEMPERATURES AND HOURLY T/TD. DISCUSSION... THE COLD FRONT CONTINUES TO RACE TO THE COAST. BREEZY NORTH WINDS WILL CONTINUE OVERNIGHT IN THE WAKE OF THE FRONT. 03/0330Z SFC OBS INDICATE THE AVERAGE WIND SPEED ACROSS THE REGION IS GENERALLY IN THE 15 TO 20 MPH RANGE...WITH A FEW POCKETS HIGHER THAN 25 MPH. WILL HOLD OFF ON A WIND ADVISORY DUE TO ISOLATED COVERAGE OF THE STRONGER WINDS AS WELL AS 03Z MSAS ANALYSIS INDICATING LOOSER SFC PRESSURE GRADIENTS FILTERING INTO THE REGION THROUGH THE NEXT FEW HOURS. HOWEVER...WINDS MAY OCCASIONALLY GUST TO NEAR 40 MPH THROUGH THE OVERNIGHT HOURS. WEAK UPPER DISTURBANCES AND SUBTLE ISENTROPIC LIFT IN THE WAKE OF THE COLD FRONT WILL KEEP THE CHANCE FOR SHOWERS AND POSSIBLY AN ISOLATED THUNDERSTORM IN THE PICTURE OVERNIGHT. THE STRONG PUNCH OF COLD/DRY AIR ADVECTION IMMEDIATELY BEHIND THE FROPA EARLIER THIS EVENING HAS BEGUN TO STABILIZE...WITH TEMPERATURES NEAR STEADY OR SLOWLY FALLING OVERNIGHT. FORECASTED LOW TEMPERATURES ARE GENERALLY ON TRACK...BUT HAVE DECREASED BY A FEW DEGREES ACROSS THE HILL COUNTRY/SRN EDWARDS PLATEAU DUE TO LOWER DEWPOINTS AND BETTER COOLING THAN PREVIOUSLY ANTICIPATED. OTHERWISE HAVE FIXED HOURLY T/TD GRIDS TO REFLECT CURRENT TRENDS IN THE WAKE OF THE FRONT. PREV DISCUSSION... /ISSUED 723 PM CST THU MAR 8 2012/ DISCUSSION... THE COLD FRONT IS MAKING GOOD PROGRESS ACROSS THE CWA...AND IS EXPECTED TO PUSH THROUGH OUR SOUTHERN TIER OF COUNTIES WITHIN THE NEXT HOUR OR SO. CHANCES FOR SHOWERS WILL CONTINUE TONIGHT AS INSTABILITY LINGERS IN THE WAKE OF THE FRONT. THERE IS ENOUGH LIFT FOR THE DEVELOPMENT OF A FEW THUNDERSTORMS...BUT COVERAGE AND LIKELIHOOD HAVE TRENDED DOWN...SO EXPECT SHOWERS TO BE THE PREDOMINANT ACTIVITY...WITH AN ISOLATED THUNDERSTORM POSSIBLE. THE CHANCE FOR SEVERE STORMS HAVE LIKEWISE DECREASED RAPIDLY AS THE SFC LAYER HAS STABILIZED CONSIDERABLY BEHIND THE FRONT (DEWPOINTS ALONE HAVE FALLEN BY A GOOD 20 OR SO DEGREES IN THE WAKE OF THE FROPA). HOWEVER...THERE IS STILL A CHANCE OF A MARGINALLY SEVERE STORM (SMALL HAIL AND STRONG WINDS) AHEAD OF AND ALONG THE FRONTAL BOUNDARY (SOUTHERN TIER OF COUNTIES) THIS EVENING. TIGHTENING PRESSURE GRADIENTS BEHIND THE FRONT HAVE ENABLED NORTHERLY WINDS TO REACH 20 TO 25 MPH WITH GUSTS OF ABOUT 30 TO FILTER INTO THE REGION. CURRENTLY EXPECT WINDS TO STAY JUST SHY OF WINDS ADVSY CRITERIA (SUSTAINED AT 26 MPH)...BUT WILL CONTINUE TO MONITOR. WILL ALSO KEEP AN EYE ON TEMPERATURES BEHIND THE FRONT AND ASSESS WHETHER MIN TEMPS WILL NEED TO BE TWEAKED. FOR NOW...HAVE ADJUSTED POP/WX/QPF GRIDS FOR CURRENT TRENDS. PREV DISCUSSION... /ISSUED 550 PM CST THU MAR 8 2012/ DISCUSSION... SEE AVIATION FOR 00Z TAFS. AVIATION... A COLD FRONT FROM NEAR K3T5 TO SOUTH OF KSAT TO SE OF KDRT WILL MOVE QUICKLY SOUTHEAST. NORTH WINDS AT 15 TO 25 KNOTS AND GUSTY ARE EXPECTED TONIGHT...ALONG WITH CIGS OF 2 THSD TO 3 THSD FT OVC. LIGHT RAIN AND SHOWERS WILL DEVELOP TONIGHT AND FRIDAY IN THE COLDER AIR. MVFR CIGS ARE EXPECTED TO CONTINUE FRIDAY... WITH CIGS CONTINUING AT 2 THSD TO 3 THSD FT OVC. NORTH WINDS AT 15 TO 25 KNOTS WILL CONTINUE ON FRIDAY. PREV DISCUSSION... /ISSUED 226 PM CST THU MAR 8 2012/ DISCUSSION... AT 20Z...THE COLD FRONT WAS MOVING INTO OUR NORTHERN-MOST COUNTIES WITH MODERATE TO STRONG COLD AIR ADVECTION BEHIND IT. TEMPERATURES WILL DIP RAPIDLY INTO THE 50S AND THEN THE 40S BEHIND THE FRONT THIS EVENING AS WINDS GUST UP TO NEAR 35 MPH. CHANCES FOR SHOWERS AND THUNDERSTORMS ARE ON THE INCREASE LATE THIS AFTERNOON INTO TONIGHT...WITH A SLIGHT RISK FOR SEVERE THUNDERSTORMS AND A LOCALLY HEAVY RAINFALL THREAT. THE THREAT FOR SEVERE THUNDERSTORMS WILL BE ALONG AND IMMEDIATELY BEHIND THE FRONT BETWEEN 3 AND 9 PM...AND GENERALLY CONFINED TO OUR NORTHEAST COUNTIES INCLUDING THE AUSTIN METRO AREA. SURFACE DEWPOINT TEMPERATURES HAVE ACTUALLY INCREASED INTO THE UPPER 60S OVER THE PAST FEW HOURS...MAKING FOR HIGHER SBCAPE VALUES APPROACHING 2000 J/KG. THIS LENDS MORE CONFIDENCE TO STRONG OR POSSIBLY SEVERE THUNDERSTORMS EARLY THIS EVENING. THE LOCALLY HEAVY RAINFALL THREAT HAS NOT CHANGED AND IS CONFINED TO AREAS ALONG AND EAST OF I-35...WITH SPOTTY 2+ INCH AMOUNTS POSSIBLE. LOCALIZED URBAN AND SMALL STREAM TYPE FLOODING CAN BE EXPECTED. "STORM TOTAL" RAINFALL AMOUNTS BETWEEN TONIGHT AND SUNDAY WILL RANGE FROM ONE HALF TO ONE INCH ACROSS THE WESTERN THIRD OF SOUTH CENTRAL TEXAS TO BETWEEN 3 AND 4 INCHES ACROSS OUR EASTERN- MOST COUNTIES.

WELL BELOW NORMAL TEMPERATURES ARE FORECAST...WITH DIURNAL TEMPERATURE RANGES 5 DEGREES OR LESS ON FRIDAY. ALTHOUGH SHOWERS/RAIN ARE EXPECTED TO DOMINATE FRIDAY THROUGH SATURDAY...A FEW THUNDERSTORMS ARE STILL POSSIBLE. THE FRONTAL LAYER WILL ERODE LATE SATURDAY INTO SUNDAY AS THE UPPER LOW KICKS-OUT OF NORTHERN MEXICO INTO TEXAS. THIS WILL LEAD TO INCREASING CHANCES FOR THUNDERSTORMS SATURDAY NIGHT INTO EARLY SUNDAY MORNING. CHANCES WILL END SUNDAY AS THE UPPER LOW MOVES NORTHEAST OUT OF THE AREA. GULF MOISTURE WILL RETURN QUICKLY NEXT WEEK AND LOWS WILL TREND TO WELL ABOVE NORMAL ONCE AGAIN. SPRING-LIKE WEATHER IS FORECAST THROUGH THE WEEK WITH LOWS IN THE 60S AND HIGHS IN THE MID 70S TO NEAR 80. FIRE WEATHER...
