AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 836 PM CDT WED OCT 13 2004 .DISCUSSION... AFTERNOON PACKAGE HAS AN EXCELLENT HANDLE ON THE AMOUNT OF PRECIP AND THE TIMING OF THE COLD FRONT. EVENING POPS WERE LOWERED SOME DUE TO WEAKENING RADAR TRENDS, BUT THE NEXT ROUND OF STORMS ARE ALREADY THREATENING OUR NORTHERN FORECAST AREA. SATELLITE IMAGERY INDICATES IMPRESSIVE DIGGING TO SUGGEST A GOOD SHOT OF THUNDERSTORMS ON EITHER SIDE OF THE FRONT AND, WITH COOLING ALOFT, A THREAT OF HAILSTORMS AND DOWNBURSTS. TIMING OF THE APPROACHING FRONT AND DISTURBANCE APPEARS SLOWER THAN FORECAST, SO MADE SOME SUBTLE ADJUSTMENTS TO WINDS AND INCREASED POPS BETWEEN DAYBREAK AND NOON THURSDAY. EXPECT FRONT TO MOVE INTO NW LLANO COUNTY AROUND 3Z AND NRN VAL VERDE BY 4Z, THEN INTO DRT BY 6Z, AUS 7Z, SAT BY 8Z. A POST FRONTAL MASS OF THUNDERSTORMS APPEARS TO BE DEVELOPING EAST OF SJT AND WILL LIKELY EXPAND TO ENGULF MUCH OF THE FORECAST AREA DURING THE EARLY MORNING HOURS. THIS WILL LIKELY PRESENT THE HIGHEST THREAT OF FLOODING. SOME AREAS HAVE HAD UP TO 3 INCHES FROM THE EVENING THUNDERSTORMS. STORM TOTALS INDICATED BY THE KEWX DOPPLER ARE MOSTLY ACCURATE WITH ONLY A FEW OF THE HIGHEST ESTIMATES CONTAMINATED BY HAIL. && .PREV DISCUSSION... HAVE DECIDED TO ISSUE FLASH FLOOD WATCH AS CONVECTION CONTINUES TO GET BETTER ORGANIZED AND RAINFALL IS ACCUMULATING. SPEED MAX APPROACHING THE BIG BEND, SHORT-WAVE MOVING EAST ACROSS NEW MEXICO, WARM FRONT ACROSS NORTHERN PORTIONS OF SOUTH CENTRAL TEXAS WILL CONTINUE TO INTERACT WITH PWS IN THE 1.5 TO 1.8 INCH RANGE TO GENERATE NUMEROUS BANDS OF CONVECTION INTO THIS EVENING. LATE THIS EVENING INTO EARLY THURSDAY, A COLD FRONT WILL SWEEP THROUGH SOUTH CENTRAL TEXAS TO MAINTAIN CONVECTIVE BANDS. WILL MENTION LOCALLY HEAVY RAINFALL WITH TRAINING OF STORMS EXPECTED DUE STEERING FLOW MOSTLY PARALLEL TO FRONTAL SURFACES. ALTHOUGH FLASH FLOOD WATCH WILL NOT BE ISSUED AS WIDESPREAD HEAVY RAINFALL CURRENTLY NOT EXPECTED, IT IS POSSIBLE THAT SOME FLOOD ADVISORIES AND WARNINGS MAY HAVE TO BE ISSUED. IN ADDITION, SOME STORMS COULD BRIEFLY BECOME SEVERE DUE CAPES OF 1K TO 2K J/KG. THESE HAVE BEEN MENTIONED IN THE HAZARDOUS WEATHER OUTLOOK WHICH WAS UPDATED AROUND 10 AM THIS MORNING. RIDGES AT THE SURFACE AND ALOFT BUILD INTO TEXAS IN THE WAKE OF THE ABOVE MENTIONED FEATURES WITH SUBSIDENCE AND COLD ADVECTION. SKIES WILL CLEAR RAPIDLY LEADING TO THE COLDEST TEMPERATURES OF THE SEASON BY FRIDAY MORNING. ON FRIDAY INTO THE WEEKEND, BOUNDARY LAYER TEMPERATURES WILL RECOVER GREATLY ON SOUTHWESTERLY BOUNDARY LAYER WINDS. BY EARLY NEXT WEEK, UPPER LOW CURRENTLY CUTOFF SOUTHWEST OF CALIFORNIA WILL OPEN UP AND BE EJECTED EASTWARD ACROSS THE SOUTHERN TIER OF STATES AS THE FLOW ALOFT BECOMES ZONAL. MOISTURE WILL RETURN BY MONDAY AND HAVE ADDED 5 TO 10 FOR POPS AS LIGHT SHOWERS POSSIBLE. HOWEVER, MADE NO MENTION IN ZONES AS FLOW ALOFT WILL BE CONFLUENT AND SOME UNCERTAINTY REMAINS. THIS COULD LEAD TO A WET PATTERN LATER NEXT WEEK INTO THE FOLLOWING WEEKEND. && .PRELIMINARY POINT TEMPS/POPS...
