AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 622 PM CDT TUE JUN 26 2012 .AVIATION... /00Z TAFS/ BASED ON LATEST RADAR TRENDS...SATELLITE IMAGERY AND STORMS MOVEMENT...OPTED TO LEAVE OUT MENTIONING OF TSRA ACROSS THE I35 SITES FOR THIS EVENING. ISOLATED STRONG TO SEVERE STORMS ARE STILL POSSIBLE THIS EVENING ALONG AND SOUTH OF I10 WITH MAIN THREATS BEING DAMAGING GUST WINDS AND SMALL HAIL. NAM12 AND WRF 3KM SOLUTIONS FOR THIS EVENING SUGGEST STRONG STORMS TO REMAIN AWAY FOR THE I35 TERMINALS WITH STORMS DISSIPATING OR MOVING OUT FROM SOUTH CENTRAL TEXAS BY MIDNIGHT. OTHERWISE...VFR CONDITIONS ARE EXPECTED TONIGHT AND WEDNESDAY WITH LIGHT WINDS OUT FROM THE SOUTHEAST. && .PREV DISCUSSION... /ISSUED 301 PM CDT TUE JUN 26 2012/ UPDATE... NO CHANGES TO THE HEAT ADVISORY THRU 9 PM...ALTHOUGH POSSIBLE DEVELOPING CONVECTION AND OUTFLOWS COULD COOL TEMPS A BIT EARLIER. HEAT INDEX VALUES TO PEAK NEAR 105 BRIEFLY ONLY OVER SWRN CWA AND NEAR I35...FOR ONLY AN HOUR OR TWO...SO NO PLANS TO REISSUE FOR WEDNESDAY AT THIS TIME. PREV DISCUSSION... /ISSUED 249 PM CDT TUE JUN 26 2012/ DISCUSSION... FOCUS ON TODAYS RECORD HEAT IS RAPIDLY CHANGING TO POTENTIAL FOR ORGANIZED SEVERE STORMS THE REMAINDER OF THE AFTERNOON AND EVENING. VISIBLE SATELLITE LOOPS SHOW A DEVELOPING ELEVATED CU FIELD OVER MUCH OF THE EASTERN HALF THE CWA AS A WEAK UPPER LEVEL CYCLONIC CIRCULATION APPROACHES FROM THE NW GULF. WITH TEMPERATURES AT 100-105 DEGREES AND STILL CLIMBING...BUFKIT INDICATED INVERTED V TYPE SOUNDINGS AT 3-9PM WHICH WOULD SUPPORT DAMAGING DOWNBURST WINDS. SPC ALREADY CONSIDERING WATCH FOR PART OF THE CWA ALTHOUGH THERE IS UNCERTAINTY OF AREA OF FOCUS DUE TO WELL DEFINED FEATURES AT THE SURFACE OR ALOFT. GFS SEEMS TO BE SUFFERING FROM CONVECTIVE FEEDBACK WITH INTENSE QPF BULLS-EYE OVER THE COASTAL PLAINS LATER THIS EVENING. OTHERWISE A WEAK EVOLVING MID LEVEL LOW PRESSURE AREA OVER SOUTH TEXAS WILL MEAN LOWER HEIGHTS FOR THE REMAINDER OF THIS WEEK. THEREFORE SHOULD SEE MAX TEMPERATURES DOWN A CATEGORY OR TWO FROM TODAYS RECORD HIGHS...ALTHOUGH PROBABLY NOT AS MUCH AS MOS GUIDANCE INDICATES. APPEARS THIS UPPER AIR WEAKNESS WILL ALLOW FOR SLIGHTLY INCREASED LOW LEVEL PRESSURE GRADIENT/MOISTURE AND THEREFORE ISOLATED-SCATTERED SEA BREEZE CONVECTION FRIDAY AND OVER THE WEEKEND. NO MENTION OF POPS FOR MON-TUE OF NEXT WEEK AS UPPER FEATURE BECOMES LESS DISCERNIBLE SO SILENT 10 PERCENT POPS MORE APPROPRIATE THAN BROAD BRUSHING LOW POPS. FIRE WEATHER... THE COMBINATION OF LOW HUMIDITIES...DRY LIGHTNING...AND STRONG GUSTY WINDS FROM ISOLATED TO SCATTERED THUNDERSTORMS THE REMAINDER OF THIS AFTERNOON AND EVENING WILL RESULT NEAR CRITICAL FIRE WEATHER CONDITIONS. WILL CONTINUE TO HIGHLIGHT THE NEAR CRITICAL...HOWEVER IF CONVECTION BECOMES MORE ORGANIZED THAN SPOTTY ISOLATED...MAY HAVE TO CONSIDER A BRIEF RED FLAG WARNING FOR THIS EVENING.
