Area forecast discussion, Nov 3, 6:58 PM CDT, 5 hours 1 minute before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 658 PM CDT SAT NOV 3 2012 .DISCUSSION... SEE AVIATION FOR 00Z TAF DISCUSSION. && .AVIATION... SCATTERED CONVECTION TO REMAIN FOCUSED OVER THE HILL COUNTY AND AREAS EAST OF I-35 THIS EVENING. ASIDE FROM A EASTERLY WIND SHIFT TO AFFECT THE I-35 TERMINALS...IMPACTS OF THE CONVECTION AND INSTABILITY ALOFT ARE MAINLY ACCOUNTED FOR IN THE SLOW RETURN OF OVERNIGHT CIG AND VSBY RESTRICTIONS. SPOTTY IFR OR WORSE CONDITIONS COULD DEVELOP AS EARLY AS 03Z...BUT WRF SIMULATED GOES PRODUCTS SUGGEST THE MAJORITY OF THE AREA REMAINING VFR THIS EVENING IN THE PRESENCE OF CONSIDERABLE MID AND HIGH LEVEL CLOUDS. A SMALL COMPLEX OF THUNDERSTORMS...POSSIBLY STEMMING FROM THE CURRENT AREA OF STORMS NORTH OF THE BIG BEND AREA...IS ALSO EXPECTED BY THE MESOSCALE MODELS TO AFFECT THE DRT AREA LATE THIS EVENING AND WORK EAST INTO THE I-35 TERMINAL LOCATIONS AFTER 07Z. BY DAYBREAK SUNDAY...CONVECTION IS EXPECTED TO BE MOSTLY EAST AND SOUTH OF THE TAF SITES...AND A PERIOD OF IFR/MVFR CONDITIONS IS EXPECTED IN THE LATE MORNING. THEN...WEAK SUBSIDENCE PATTERN IN THE FLOW ALOFT SHOULD SHOULD HELP CLEAR SKIES IN THE AFTERNOON AND EVENING HOURS. && .PREV DISCUSSION... /ISSUED 331 PM CDT SAT NOV 3 2012/ DISCUSSION... SCATTERED SHOWERS AND THUNDERSTORMS CONTINUED ACROSS EASTERN AREAS DUE TO SOLAR HEATING AND AHEAD OF AN UPPER LEVEL SHEAR AXIS. SCATTERED SHOWERS AND THUNDERSTORMS WERE ALSO DEVELOPING OVER THE NORTHERN HILL COUNTRY NEAR A SURFACE BOUNDARY EXTENDING FROM CENTRAL TEXAS INTO THE TRANS PECOS AND AHEAD OF AN UPPER LEVEL LOW MOVING EAST ACROSS WESTERN TEXAS/SOUTHEASTERN NEW MEXICO. THE SHOWERS AND THUNDERSTORMS OVER THE EAST WILL DISSIPATE EARLY THIS EVENING WITH LOSS OF HEATING AFTER SUNSET AS THE SHEAR AXIS MOVES EAST. THE HI-RES NMM AND ARW...AS WELL AS THE NAM CONTINUE TO SHOW THE SHOWERS AND THUNDERSTORMS NEAR THE SURFACE BOUNDARY ORGANIZING AND MOVING SOUTHEAST ACROSS SOUTH CENTRAL TEXAS TONIGHT AS THE UPPER LEVEL LOW MOVES ACROSS CENTRAL TEXAS. WILL FOLLOW THIS TREND AND GO WITH SCATTERED SHOWERS AND THUNDERSTORMS FOR TONIGHT. STEEP LAPSE RATES AND MODERATE INSTABILITY SUGGEST THE POTENTIAL FOR HAIL AND GUSTY WINDS. SOME RESIDUAL SURFACE BOUNDARIES...SUFFICIENT MOISTURE AND SOLAR HEATING WILL ALLOW FOR ISOLATED SHOWERS AND THUNDERSTORMS TO DEVELOP ON SUNDAY. ANOTHER MAINLY SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS IS ON MONDAY INTO MONDAY NIGHT WHEN AN UPPER LEVEL SHORT-WAVE DROPS SOUTHEAST ACROSS THE PLAINS FORCING A COLD FRONT ACROSS SOUTH CENTRAL TEXAS. TEMPERATURES WILL REMAIN ABOVE AVERAGE FOR TONIGHT THROUGH MONDAY. THE MAIN IMPACT OF THE FRONT AND SURFACE HIGH BEHIND IT WILL BE TO DRY THE AIRMASS. FOR TUESDAY THROUGH THURSDAY...THE BULK OF THE COLD ADVECTION PASSES WELL OFF TO THE EAST WITH THE MUCH LOWER DEWPOINTS BEING THE MAIN REASON THAT LOW TEMPERATURES WILL BE NEAR OR BELOW AVERAGE WHILE HIGH TEMPERATURES REMAIN SLIGHTLY ABOVE AVERAGE. THE SURFACE HIGH MOVES OFF TO THE EAST BY THURSDAY WITH SURFACE PRESSURE FALLS IN THE PLAINS AHEAD OF A DEEP UPPER LEVEL LOW MOVING ACROSS THE WESTERN STATES. A STRONG SOUTHERLY LOWER LEVEL FLOW RETURNS WITH RAPIDLY INCREASING MOISTURE MAKING FRIDAY INTO SATURDAY FEEL HUMID WITH WELL ABOVE AVERAGE TEMPERATURES. SOME STREAMER SHOWERS ARE POSSIBLE SATURDAY IN THE EAST. JUST BEYOND THIS FORECAST...THE GFS AND ECMWF DIFFER ON THE PROGRESSION THE UPPER TROUGH AND STRONG COLD FRONT. THE GFS IS FASTER BRINGING THEM THROUGH SATURDAY NIGHT INTO EARLY SUNDAY WHILE THE ECMWF BRINGS THEM THROUGH SUNDAY NIGHT INTO EARLY MONDAY. && .PRELIMINARY POINT TEMPS/POPS...
