NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at Sep 7, 5:35 AM CST, 55 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 635 AM CDT SUN SEP 7 2014 .AVIATION...THE CONVECTION THAT OCCURRED OVER THE AERODROMES IN THE PREVIOUS SEVERAL HOURS HAS ENDED...LEAVING CLOUDINESS BEHIND. VFR LOOKS TO PREVAIL THROUGH THE NEXT SEVERAL HOURS AS SURFACE WINDS VEER WHILE CEILINGS RISE. VFR SHOULD PERSIST THROUGH THE OVERNIGHT HOURS TONIGHT AND INTO MONDAY MORNING WITH GENERALLY LIGHT WINDS AND FAVORABLE CLOUD DECKS EXPECTED. && .PREV DISCUSSION... /ISSUED 406 AM CDT SUN SEP 7 2014/ SHORT TERM (TODAY THROUGH MONDAY)... EARLY MORNING SURFACE OBSERVATIONS SHOW A COLD FRONT LOCATED ROUGHLY ALONG A DEL RIO TO KERRVILLE TO AUSTIN LINE. THIS BOUNDARY IS WEAK... BUT IS SERVING AS A FOCUS FOR CONVECTION THIS MORNING. BASED ON CURRENT RADAR TRENDS AND THE LATEST HI-RES MODELS...WE/LL SHOW THE HIGHER RAIN CHANCES FOR AREAS GENERALLY NORTH OF THE HIGHWAY 90 CORRIDOR THROUGH THE EARLY MORNING HOURS. LOCALLY HEAVY RAINFALL AND MINOR FLOODING REMAIN A CONCERN...ESPECIALLY GIVEN THE AMOUNT OF MOISTURE AND SLOW STORM MOVEMENT. THE MODELS SUGGEST A GRADUAL WEAKENING TREND IS EXPECTED AROUND SUNRISE THROUGH MOST OF THE MORNING HOURS AS THE LOW-LEVELS STABILIZE. THE COLD FRONT WILL GRADUALLY WEAKEN THIS AFTERNOON...BUT IS STILL EXPECTED TO AID IN THE DEVELOPMENT OF CONVECTION. THIS BOUNDARY ALONG WITH DAYTIME HEATING IS EXPECTED TO RESULT IN ANOTHER ROUND OF AFTERNOON AND EARLY EVENING CONVECTION TODAY. CAN/T RULE OUT SOME LOCALLY HEAVY RAINFALL GIVEN THE AMOUNT OF MOISTURE AND WEAK FLOW ALOFT. THE MOST FAVORED AREA FOR LOCALLY HEAVY RAINFALL APPEARS TO REMAIN NEAR THE COASTAL PLAINS WHERE HIGHER DEWPOINTS ARE EXPECTED. A DECREASE IN CONVECTION IS EXPECTED BY LATE EVENING WITH THE LOSS OF DAYTIME HEATING. ON MONDAY...SOUTHEASTERLY WINDS RETURN AS THE SUBTROPICAL RIDGE AXIS BEGINS TO BUILD OVER TEXAS. THE LATEST MODEL GUIDANCE SUGGESTS WE COULD SEE ANOTHER SHOT AT CONVECTION ACROSS MOST OF THE REGION. RAIN CHANCES REMAIN HIGHEST OVER THE COASTAL PLAINS...BUT WE DID OPT TO INCLUDE ISOLATED SHOWERS AND THUNDERSTORMS FOR AREAS GENERALLY WEST OF HIGHWAY 83. LONG TERM (MONDAY NIGHT THROUGH SATURDAY)... THE EARLY AND MIDDLE PORTION OF THE WORK WEEK WILL SEE A DRYING AND WARMING TREND AS HIGH PRESSURE ALOFT REMAINS THE DOMINANT WEATHER FEATURE. TEMPERATURES WILL REMAIN ABOVE NORMAL AND GIVEN A PERSISTENT SOUTH TO SOUTHEAST WIND AND PLENTY OF LOW-LEVEL MOISTURE... WE/LL NEED TO MONITOR FOR RISING HEAT INDICES. FOR NOW...IT APPEARS AREAS ALONG AND EAST OF I-35 COULD SEE HEAT INDICES APPROACHING 105 DEGREES ON WEDNESDAY AND THURSDAY. A CHANGE IN THE WEATHER PATTERN IS EXPECTED LATE IN THE WEEK AS A COLD FRONT MOVES INTO THE SOUTHERN U.S. PLAINS. THE MEDIUM RANGE MODELS CONTINUE TO DIFFER WITH THE TIMING OF THE COLD FRONT WITH THE CANADIAN SOLUTION FASTEST AND THE ECMWF SLOWEST. FOR NOW...WE/LL COMPROMISE AND FAVOR THE GFS...WHICH BRINGS THE COLD FRONT INTO THE REGION ON FRIDAY. WE STILL EXPECT A CHANCE FOR RAIN WITH THE COLD FRONT...BUT MOS POPS CONTINUE TO REMAIN IN THE LOW END CHANCE CATEGORY AT BEST. IN GENERAL...WE/LL RETAIN 20-30% POPS AND AWAIT FUTURE MODEL DATA BEFORE GOING MUCH HIGHER WITH RAIN CHANCES. TEMPERATURES WILL DROP BEHIND THE COLD FRONT AND WE/VE GENERALLY FOLLOWED A BLEND OF THE MEX AND ECMWF MOS GUIDANCE LATE IN THE FORECAST PERIOD. && .PRELIMINARY POINT TEMPS/POPS...
