NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at May 6, 5:39 PM CST, 3 hours 4 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 639 PM CDT TUE MAY 6 2014 .AVIATION... MODERATE TO STRONG SOUTHERLY FLOW WILL CONTINUE THROUGH THIS FORECAST PERIOD. MOISTURE CONTINUES TO INCREASE ACROSS THE REGION AND CURRENT VFR CIGS WILL BECOME MVFR 05Z-06Z THEN BECOMING IFR AFTER 07Z. KDRT WILL SEE MVFR CIGS DEVELOP AROUND 11Z. AFTER 02Z THURSDAY EXPECT TO SEE MVFR CIGS DEVELOP. S/SE WINDS 15 TO 20 KNOTS WITH GUSTS TO 25 KNOTS WILL CONTINUE THROUGH 05Z THEN DECREASE TO 10 TO 15 KNOTS. AFTER 15Z WINDS WILL INCREASE ONCE AGAIN TO THE 15 TO 20 KNOT RANGE WITH GUSTS TO 25 KNOTS. PATCHY FOG IS POSSIBLE ALONG THE ESCARPMENT AND POINTS EAST AND SOUTH. WILL HAVE TO WATCH FOR THUNDERSTORMS TO DEVELOP WEDNESDAY AFTERNOON AFTER 19Z OVER THE MOUNTAINS IN MEXICO. THESE STORMS COULD MOVE ACROSS THE RIO GRANDE PLAINS DURING THE LATE AFTERNOON AND INTO THE EVENING AND POINTS FURTHER EAST INTO THE EVENING AND OVERNIGHT. && .PREV DISCUSSION... /ISSUED 320 PM CDT TUE MAY 6 2014/ SHORT TERM (TONIGHT THROUGH WEDNESDAY NIGHT)... ANOTHER MILD AND HUMID NIGHT IS IN STORE AS SOUTHERLY WINDS CONTINUE TO PUMP GULF MOISTURE INTO THE REGION. THERE IS THE POTENTIAL FOR THUNDERSTORMS TO DEVELOP ACROSS THE SERRANIAS DEL BURRO IN NERN MEXICO LATE THIS AFTERNOON AND INTO THE EVENING. MOST OF THESE STORMS WILL DISSIPATE WITH THE LOSS OF HEATING BEFORE BEING ABLE TO CROSS THE RIO GRANDE...BUT THERE IS STILL THE POTENTIAL FOR AN ISOLATED STORM OR TWO TO MAKE IT INTO THE TEXAS RIO GRANDE PLAINS. THE APPROACH OF A MID/UPPER TROUGH WILL ENHANCE FLOW OFF THE GULF ON WEDNESDAY. THE MOISTENING LOWER LEVELS AND DESTABILIZATION ALOFT WILL LEAD TO CLOUDS LINGERING THROUGHOUT THE DAY...AND A CHANCE FOR RAIN. THE CHANCE FOR RAIN WILL INCREASE WEDNESDAY EVENING...WITH A BETTER LIKELIHOOD OF SERRANIAS DEL BURRO STORMS BEING ABLE TO PROGRESS FARTHER EASTWARD. ADDITIONAL CONVECTION IS EXPECTED TO DEVELOP ALONG THE DRYLINE IN WEST CENTRAL TEXAS AND PUSH EASTWARD DURING THE LATE AFTERNOON/EVENING HOURS. SFC INSTABILITY COURTESY OF WARM AFTERNOON TEMPERATURES AND MOIST DEWPOINTS IN THE 60S WILL COMBINE WITH INSTABILITY ALOFT AND PROMOTE THE DEVELOPMENT OF SUPERCELLS WITH LARGE HAIL AND DAMAGING WINDS. THROUGH WEDNESDAY NIGHT...THE HIGHEST RISK FOR SEVERE STORMS WILL BE ACROSS WEST CENTRAL/NORTH CENTRAL TEXAS AND INTO THE SOUTHERN EDWARDS PLATEAU/WESTERN RIO GRANDE PLAINS. LONG TERM (THURSDAY THROUGH TUESDAY)... AS THE MID/UPPER TROUGH MOVES EASTWARD ON THURSDAY...CONVECTIVE ACTIVITY WILL LIKEWISE SHIFT EASTWARD. THE BEST COVERAGE OF STORMS IS EXPECTED TO BE DURING THE DAY ON THURSDAY AS A WEAK S/W TROUGH PASSES THROUGH THE SRN EDGE OF THE MID/UPPER TROUGH...AND COMBINES WITH DIURNAL INSTABILITY. SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED ACROSS MOST OF THE CWA THROUGHOUT THE DAY ON THURSDAY AND SHIFT TO SE/ERN PORTIONS OF THE REGION THURSDAY NIGHT. MODELS CONTINUE TO INDICATE DIFFERENCES IN THE SPEED OF THE UPPER TROUGH AND HOW SUPPORTIVE THE ENVIRONMENT AHEAD OF THE TROUGH WILL BE FOR STRONG/SEVERE STORMS. HAVE FOLLOWED SPC'S GUIDANCE INDICATING A SLIGHT RISK FOR SEVERE STORMS ACROSS THE HILL COUNTRY/I-35 CORRIDOR/CENTRAL PORTIONS OF THE CWA. THE CHANCE FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE FRIDAY AND FRIDAY NIGHT MAINLY ACROSS AREAS SE OF THE ESCARPMENT...AND FURTHER TAPERING OFF FROM WEST TO EAST ON SATURDAY AS THE UPPER TROUGH AXIS FINALLY EJECTS INTO THE ERN U.S. THE UPPER LEVELS WILL TRANSITION FROM TROFFINESS TO ZONAL FLOW/WEAK RIDGING OVER THE WEEKEND. SIMILAR TO THE 00Z RUN OF MID/LONG RANGE MODELS...THERE ARE SIGNIFICANT DIFFERENCES THROUGH THE EXTENDED FORECAST PERIOD. THE ECMWF INDICATES AN UPPER TROUGH DEVELOPING ACROSS THE NWRN U.S. OVER THE WEEKEND AND MOVING INTO THE CENTRAL PLAINS EARLY NEXT WEEK WHILE THE GFS KEEPS THE UPPER TROUGH FARTHER NORTH RESULTING IN NEARLY ZONAL FLOW PERSISTING ACROSS MUCH OF TEXAS. HIGH TEMPERATURES WILL BE NEAR OR SLIGHTLY ABOVE AVERAGE FOR EARLY MAY THROUGH THE END OF THE WEEK. LOWS WILL BE MUCH WARMER THAN NORMAL DUE TO THE PERSISTENTLY JUICY LOWER LEVELS. AS THE MID-LEVELS BEGIN TO DRY OVER THE WEEKEND...THERE WILL BE A FEW MORE BREAKS IN CLOUD COVER...ENABLING AFTERNOON TEMPERATURES TO CLIMB JUST A FEW DEGREES WARMER. && .PRELIMINARY POINT TEMPS/POPS...
