IFR CIGS/VSBYS ARE LIKELY IN PRECIPITATION. SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS CAN BE EXPECTED THROUGH 00Z, THEN A BRIEF LULL BETWEEN 00Z AND 04Z, THEN NUMEROUS TO WIDESPREAD AREAS OF RAIN AND SHOWERS WITH SCATTERED THUNDERSTORMS DEVELOPING AFTER 04Z ESPECIALLY ALONG AND EAST OF A COT TO JCT LINE. SE TO E WINDS OF 5 TO 15 KTS WILL PREVAIL WITH SOME GUSTS TO 35 KTS IN AND NEAR THUNDERSTORMS. && .PREV DISCUSSION... /ISSUED 1044 AM CDT THU JUL 26 2007/ UPDATE...NEW NAM MODEL THIS MORNING HAS US CONCERNED. MODEL SHOWS NEAR PERPENDICULAR FLOW (TO THE ESCARPMENT) IN THE LOWER LEVELS BY LATE TONIGHT WITH SOURCE REGION FROM THE DEEP SOUTHWEST GULF. COMBINED WITH DYNAMICS ALOFT IN THE ALREADY TROPIC-LIKE ATMOSPHERE, HAVE RAISED PROBABILITIES TONIGHT THROUGHOUT THE EASTERN HALF OF THE CWA AND UPPED QPF AMOUNTS SIGNIFICANTLY ALONG THE ESCARPMENT. PERPENDICULAR FLOW OF 30 TO 40 KTS AT THE 925 MB LEVEL IN THIS KIND OF ENVIRONMENT LEADS US TO BELIEVE SERIOUS FLOOD PROBLEMS COULD DEVELOP ALONG THE NORTHEAST SOUTHWEST ESCARPMENT FROM AUSTIN/GEORGETOWN AREA DOWN TO SAN ANTONIO TONIGHT. UPDATED FORECASTS AND GRIDS OUT SOON. PREV DISCUSSION... /ISSUED 635 AM CDT THU JUL 26 2007/ AVIATION... SCATTERED TO NUMEROUS SHRA/TSRA WILL MOVE NORTHWARD ACROSS THE AREA FROM THE COASTAL BEND.

A LIGHT TO MODERATE SOUTHEAST LOW LEVEL FLOW IS FORECAST TODAY AND TONIGHT...WITH CONVECTIVE WIND GUSTS OF 30 KTS POSSIBLE. PREV DISCUSSION... /ISSUED 356 AM CDT THU JUL 26 2007/ DISCUSSION... THERES NOT MUCH CHANGE IN THE ONGOING FORECAST. THE 500MB LOW WHICH CAN BE SEEN ON WV OVER THE RIO GRANDE IN VAL VERDE COUNTY WILL DRIFT SLOWLY TO THE SOUTHWEST OVER THE NEXT SEVERAL DAYS. AT THE SAME TIME THE BOUNDARY LAYER FLOW WILL BE FROM THE SOUTH TO SOUTHEAST WHICH WILL CONTINUE TO BRING MOISTURE INTO SOUTH CENTRAL TEXAS. THIS ALL MEANS MORE RAIN. POPS WILL REMAIN IN THE CHANCE TO LIKELY CATEGORIES FOR MOST OF THE CWA THROUGH SATURDAY. WILL CONTINUE THE FLASH FLOOD WATCH UNTIL MIDNIGHT TONIGHT. IN ADDITION SKIES WILL BE MAINLY CLOUDY AND THIS WILL KEEP HIGH TEMPS WELL BE BELOW NORMAL. BY SUNDAY THE UPPER LOW WILL HAVE MOVED FAR ENOUGH AWAY TO ALLOW FOR A DECREASE IN POPS.
