AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 1152 PM CDT SAT OCT 12 2013 .AVIATION... STARTING TO SEE SOME PATCHY MVFR CIGS DEVELOP. BELIEVE WE'LL START SEEING INCREASING RAIN COVERAGE LATE TONIGHT STARTING FROM W/NW AS APPROACHING S/W FROM SW INTERACTS WITH DEEP MOISTURE & BOUNDARIES ALREADY IN PLACE. AFTER WE SEE SOME HEATING AFTER SUNRISE...COVERAGE WILL FURTHER EXPAND INLAND. EXPECT MAINLY MVFR CONDITIONS IN/NEAR PRECIP - THOUGH AS WE SAW TODAY - LOCALLY HEAVY RAIN WILL ALSO BE POSSIBLE ESP WHERE BOUNDARIES END UP SERVING AS A TRAINING FOCUS. DECREASING PRECIP FROM N TO S AFTER 00Z MONDAY. 47 && .PREV DISCUSSION... /ISSUED 915 PM CDT SAT OCT 12 2013/ THE BULK OF THE CONVECTION OVER SOUTHWESTERN LA NOW FOCUSING ALONG WHAT COULD BE A MID-LEVEL (NEAR 850 MB) BOUNDARY PER KLCH RAOBS. NOT OUT OF THE WOODS YET AS A SHORTWAVE MOVING QUICKLY OUT OF NORTHERN MEXICO...OVERTOP CENTRAL TX SURFACE TROUGHING...WILL LIKELY RE-FIRE ACTIVITY OVER CENTRAL TX/(SOUTH)WESTERN CWA EARLY SUNDAY MORNING. NO OBVIOUS SKILL IN DETERMINING THE ACTUAL LOCALE /TIMING OF THE NEXT ROUND...BUT WITH THIS APPROACHING SHORTWAVE ENTERING A FAIRLY NON-WORKED AIR MASS OVER THE WEST- SOUTHWEST/COASTAL FA BETWEEN 09Z AND 15Z IS WHERE THE HIGHER POPS WILL BEGIN. AMPLE LL CONVERGENCE OVER CENTRAL TEXAS PER THE SOUTHERN MOVEMENT OF THE SYNOPTIC BOUNDARY TONIGHT WILL ALSO POINT TO HIGHER SUNDAY MORNING NORTH(EAST)ERN COUNTY POPS. THINKING IS THAT MORE-SOUTHERN BASED SCATTERED CONVECTION WILL FORM INTO A MORE ORGANIZED EAST-WEST (QUASI)LINEAR SYSTEM THAT WILL PROPAGATE NORTH TO EAST WITH BOTH THE NE-EXITING SHORTWAVE AND INTERIOR WARMING INTO THE LOW-MID 80S. OF COURSE...NUMEROUS RESIDUAL BOUNDARIES WITHIN THIS 2 INCH PWAT AIR (NEAR 2 STD DEV FOR MID- OCTOBER STANDARDS) WILL PROVIDE THE FOCUS FOR THE RANDOM FORMATION OF CELL RE-DEVELOPMENT.
