Area forecast discussion, Jun 23, 6:25 PM CDT, 2 hours 2 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 625 PM CDT MON JUN 23 2014 .AVIATION... VFR CONDITIONS HAVE BROKEN OUT IN THE WAKE OF THE CONVECTION THIS MORNING. ISOLATED SHOWERS HAVE DEVELOPED NEAR SAN ANGELO...EAST OF THE KILLEEN...AND TO THE SOUTHWEST OF SAN ANTONIO IN THE LAST TWO HOURS BUT HAVE SHOWN VERY LITTLE MOVEMENT. THE TERMINALS SHOULD REMAIN DRY THIS EVENING SO NO PRECIPITATION IS MENTIONED. THE SEASONAL PATTERN OF MVFR STATUS WILL CONTINUE TONIGHT. HAVE GONE WITH A PERSISTENCE FORECAST BASED ON THE LAST FEW DAYS...BRINGING THE STRATUS IN AROUND 06Z/07Z AND MIXING IT OUT BY 17Z ON TUESDAY. SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE ACROSS SOUTH CENTRAL TEXAS AGAIN TOMORROW...BUT ARE NOT MENTIONED IN THE TAFS DUE TO UNCERTAINTY IN COVERAGE AND LOCATION. WINDS THIS EVENING AND OVERNIGHT WILL GENERALLY BE OUT OF THE SOUTHEAST AROUND 10 KNOTS. SOME OCCASIONAL LOCALIZED WIND SHIFTS ARE POSSIBLE THIS EVENING DUE TO MULTIPLE SURFACE BOUNDARIES LEFT BEHIND BY THE MORNING CONVECTION MOVING ACROSS THE AREA. WINDS ON TUESDAY WILL BE OUT OF THE SOUTH AGAIN AT 10-15 KNOTS. TREADWAY && .PREV DISCUSSION... /ISSUED 300 PM CDT MON JUN 23 2014/ SHORT TERM (TONIGHT THROUGH TUESDAY NIGHT)... SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS SERN PORTIONS OF THE CWA AS THE REMNANTS OF THE SQUALL LINE INTERACT WITH THE SEA-BREEZE. ANOTHER ROUND OF CONVECTION IS EXPECTED TO DEVELOP TONIGHT ACROSS NORTH CENTRAL TEXAS...WITH THE CONVECTION REACHING THE HILL COUNTRY AND NRN PORTIONS OF SOUTH CENTRAL TEXAS BEFORE SUNRISE. LINGERING BOUNDARIES FROM TODAY'S ACTIVITY AND DIURNAL HEATING WILL FURTHER DESTABILIZE THE ENVIRONMENT AS THE NEW BATCH OF CONVECTION ENTERS THE CWA...LEADING TO AN INCREASE IN COVERAGE DURING THE DAY. PW VALUES WILL AGAIN BE 1.5-1.75+ ACROSS THE CWA...SO SIMILAR TO TODAY'S CONVECTION...LOCALLY HEAVY DOWNPOURS ARE EXPECTED. THE RAINS WILL GENERALLY BE A WELCOME SIGHT...BUT THE RUNOFF FROM THE HEAVY RAIN COULD LEAD TO ISOLATED FLASH FLOODING SHOULD IT OCCUR OVER FLOOD-PRONE AREAS. CONVECTION WILL WANE WITH THE LOSS OF DAYTIME HEATING...BUT ISOLATED TO SCATTERED STORMS WILL LINGER INTO THE OVERNIGHT HOURS MAINLY ACROSS ERN PORTIONS OF THE CWA. LONG TERM (WEDNESDAY THROUGH MONDAY)... A N-S ORIENTED MID-LEVEL SHEAR AXIS WILL MOVE INTO THE ERN CWA TUES NIGHT/EARLY WEDS AND REMAIN NEARLY STATIONARY THROUGH THE REST OF THE WEEK. THE SHEAR AXIS AND AN UNSETTLED PATTERN ALOFT WILL LEAD TO CHANCES FOR RAIN MAINLY ACROSS THE ERN HALF OF THE CWA EACH DAY WITH DIURNAL INCREASES IN COVERAGE. THE BEST COVERAGE OF STORMS IS EXPECTED ON WEDNESDAY AS AN UPPER LEVEL S/W TROUGH SKIRTS THE SRN PLAINS. ONSHORE FLOW WILL KEEP THE LOWER LEVELS MOISTENED AND COMBINE WITH A TAP OF ERN PACIFIC TROPICAL MOISTURE IN THE UPPER LEVELS TO KEEP PW VALUES GENERALLY 1.75-2 INCHES. OCCASIONAL LOCALLY HEAVY DOWNPOURS ARE POSSIBLE. HOWEVER...GIVEN THE POTENTIAL FOR SUBTLE MOVEMENTS OF THE MID-LEVEL SHEAR AXIS TO HAVE LARGE IMPACTS ON COVERAGE OF CONVECTION...WILL HOLD OFF ON EXPLICITLY MENTIONING HEAVY RAIN IN THE GRIDS AND WILL CONTINUE TO ADDRESS THE SITUATION IN THE HWO. MODELS AREN'T ENTIRELY SURE WHAT TO DO WITH THE SHEAR AXIS BY THE WEEKEND BUT SUGGEST CHANCES FOR RAIN WILL CONTINUE BUT GENERALLY BE CONFINED TO THE COASTAL PLAINS. THE CHANCES FOR RAIN AND HIGH MOISTURE LEVELS ACROSS THE REGION WILL KEEP HIGHS NEAR AVERAGE AND LOWS NEAR/SLIGHTLY ABOVE AVERAGE FOR LATE JUNE. && .PRELIMINARY POINT TEMPS/POPS...
