AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 328 PM CDT SAT AUG 24 2013 .SHORT TERM (TONIGHT THROUGH SUNDAY NIGHT)... THE LATEST WATER VAPOR SATELLITE IMAGERY SHOWS AN AREA OF SUBSIDENCE MOVING THROUGH EAST TEXAS INTO PORTIONS OF CENTRAL TEXAS. THIS SHOULD KEEP CONVECTION LIMITED TODAY...WITH MAINLY ISOLATED COVERAGE EXPECTED FOR THE REMAINDER OF THIS AFTERNOON. MOST CONVECTION SHOULD BE TIED CLOSELY TO DIURNAL HEATING...BUT CAN/T RULE OUT SOME ISOLATED STORMS THIS EVENING ACROSS THE WESTERN HILL COUNTRY AND RIO GRANDE PLAINS WHERE SHORT RANGE MODELS SHOW A MID-LEVEL THETA-E RIDGE AXIS. OTHER FEATURES OF INTEREST AS NOTED ON WV SATELLITE INCLUDE A TROUGH IN THE NORTH CENTRAL GULF OF MEXICO AND A TROPICAL WAVE ON THE EAST SIDE OF THE YUCATAN PENINSULA. THE ABOVE MENTIONED TROUGH WILL GRADUALLY SLIDE WESTWARD THROUGH THE SHORT TERM PORTION OF THE FORECAST. AS THE TROUGH APPROACHES... WE EXPECT AN INCREASE IN TROPICAL MOISTURE TO GRADUALLY SPREAD WESTWARD ACROSS SOUTH CENTRAL TEXAS. ON SUNDAY...ATMOSPHERIC MOISTURE CONTENT WILL BE GREATEST ACROSS THE COASTAL PLAINS AND WE WILL CONTINUE TO KEEP HIGHER RAIN CHANCES HERE. MOISTURE CONTINUES TO SLOWLY INCREASE THROUGH SUNDAY NIGHT...SO WE EXPECT SOME OVERNIGHT CONVECTION... ESPECIALLY NEAR THE COASTAL PLAINS. && .LONG TERM (MONDAY THROUGH SATURDAY)... DEEP LAYER MOISTURE CONTINUES TO INCREASE ON MONDAY AS PRECIPITABLE WATER VALUES RISE TO NEAR 1.5" SOUTHERN EDWARDS PLATEAU TO NEAR 2.25" ALONG THE COASTAL PLAINS. RAIN CHANCES ON MONDAY WILL BE HIGHEST FOR AREAS GENERALLY ALONG AND EAST OF I-35. GIVEN THE AMOUNT OF MOISTURE... LOCALLY HEAVY RAINFALL WILL BE POSSIBLE WITH THE STRONGER STORMS. MOISTURE LEVELS SLOWLY DECREASE ON TUESDAY...BUT CAN/T RULE OUT MORE SHOWER AND THUNDERSTORM ACTIVITY DURING THE PEAK HEATING HOURS. FOR NOW...WE HAVE GONE WITH A 20% CHANCE OF RAIN ON TUESDAY...BUT THIS MAY NEED TO BE INCREASED. FOR THE MIDDLE AND LATTER HALF OF THE UPCOMING WORK WEEK...THE SUBTROPICAL RIDGE AXIS WILL REMAIN THE DOMINANT WEATHER FEATURE. THIS WILL LIKELY BRING DRY WEATHER ALONG WITH ABOVE NORMAL TEMPERATURES TO SOUTH CENTRAL TEXAS THROUGH THE REMAINDER OF THE FORECAST PERIOD. && .PRELIMINARY POINT TEMPS/POPS...
