AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 645 AM CDT FRI APR 16 2010 .DISCUSSION... SEE AVIATION SECTION BELOW. && .AVIATION... THE AXIS OF HIGHEST PWATS HAS SHIFTED TO THE EAST AND SETTLED OVER THE I-35 TERMINALS. THIS HAS PROMOTED IFR CONDITIONS AT THE I-35 TERMINALS WHILE DRT BOUNCES BETWEEN IFR AND MVFR. A SHORTWAVE IS PROGRESSING AROUND THE UPPER LOW AND HELPING IN THE REDEVELOPMENT OF SHOWERS IN VAL VERDE COUNTY. THESE SHOWERS WILL BECOME WIDESPREAD AND REACH ALL TERMINALS WITHIN THE FIRST SIX HOURS OF THE TAF. AFTER 18Z...THUNDERSTORMS WILL REACH THE I-35 TERMINALS AND CONFIDENCE IS LOW THAT THUNDERSTORMS WILL REACH DRT. CEILINGS WILL DROP BACK TO IFR OVERNIGHT AS HIGH PWATS REMAIN OVER THE AREA. && .PREV DISCUSSION... /ISSUED 426 AM CDT FRI APR 16 2010/ DISCUSSION... WELL ABOVE NORMAL PWATS AND A DIFFLUENT UPPER LEVEL FLOW CONTINUE OVER SOUTH CENTRAL TEXAS AND WILL PRODUCE NUMEROUS SHOWERS... ISOLATED THUNDERSTORMS AND LOCALLY HEAVY RAINFALL TODAY. RAINFALL AMOUNTS WILL GENERALLY RANGE FROM ONE HALF TO ONE INCH TODAY INTO TONIGHT...BUT SPOTTY RAINFALL TOTALS BETWEEN THREE AND FIVE INCHES ARE POSSIBLE AND MAY LEAD TO MORE FLASH FLOODING.

THAT SAID...THE AREA MOST LIKELY TO RECEIVE THE HIGHER RAINFALL AMOUNTS IS BETWEEN HIGHWAYS 281 AND 277... INCLUDING PORTIONS OF BEXAR COUNTY. POPS WILL TREND DOWN OVER THE WEEKEND AS WESTERLY FLOW ALOFT BRINGS DRIER AIR AND A SHORTWAVE RIDGE BUILDS OVER THE SOUTHERN ROCKIES AND NORTHERN MEXICO...AND MOVES INTO WEST TEXAS LATE SUNDAY. CONVECTION WILL STILL BE POSSIBLE...ESPECIALLY ON SATURDAY WHEN A WEAK COLD FRONT WILL SLIDE INTO OUR AREA. THERE IS GOOD AGREEMENT AMONG THE 00Z MEDIUM RANGE SOLUTIONS ON A SHORTWAVE TROUGH MOVING WEST ACROSS NORTHERN MEXICO ON MONDAY AND ACROSS OUR AREA MONDAY NIGHT INTO TUESDAY...BRINGING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS. WE'LL GET A BREAK ON WEDNESDAY AND THURSDAY...BUT WILL LOAD GULF MOISTURE NEXT FRIDAY IN ADVANCE OF A LARGE STORM SYSTEM FORECAST TO MOVE ACROSS THE SOUTHERN ROCKIES.
