AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 316 PM CDT SAT NOV 3 2012 .DISCUSSION... AN UNSETTLED WEATHER PATTERN IS TAKING SHAPE FOR SOUTHEAST TEXAS. A WEAK 500 MB TROUGH EXTENDS FROM THE WESTERN GREAT LAKES INTO TEXAS. THE TROUGH AXIS LOOKS TO REMAIN WEST OF SE TX THROUGH MONDAY SO AM EXPECTING SCT SHRA/TSRA THROUGH THE PERIOD. THE GFS IS FASTER WITH THE TROUGH AXIS AND HAS IT THROUGH THE AREA BY SUNDAY MORNING. PREFER THE SLOWER NAM/ECMWF. THE NAM PERFORMED WELL TODAY AND FEEL IT INITIALIZED BEST TODAY. THE NAM ADVERTISES A STRONGER DISTURBANCE MOVING ACROSS CENTRAL TEXAS INTO SE TX OVERNIGHT. OMEGA VALUES LOOK RATHER IMPRESSIVE AND AM A BIT CONCERNED THAT THE POP FCST MAY BE UNDERDONE. THAT SAID...THERE SHOULD BE A BREAK IN THE PRECIP THIS EVENING WITH COVERAGE INCREASING AGAIN AFTER MIDNIGHT. UPPER FLOW REMAINS DIVERGENT THROUGH SUNDAY MORNING WHICH SHOULD ENHANCE LIFT. THE UPPER FLOW BECOMES CONFLUENT IN THE AFTERNOON AND FEEL RAIN CHANCES SHOULD BE ON THE WANE IN THE AFTN. A COLD FRONT OVER NORTH TEXAS SHOULD STAY NORTH OF THE REGION THROUGH MONDAY. A STRONGER S/WV EMBEDDED IN THE N-NW FLOW ALOFT SHOULD HELP TO DEEPEN THE UPPER TROUGH TO THE EAST AND THIS SHOULD ALL HELP TO DRIVE THE FRONT SOUTHWARD AND ACROSS THE REGION BY MONDAY EVENING. UPPER FLOW LOOKS TO BE CONFLUENT SO SURFACE CONVERGENCE ALONG THE BOUNDARY WILL BE THE ONLY CATALYST FOR RAIN. ELECTION DAY LOOKS NICE WITH COOL TEMPS. SKIES ARE EXPECTED TO CLEAR AND MOSTLY SUNNY SKIES ARE EXPECTED BY TUES AFTERNOON. THE REST OF THE WEEK LOOKS DRY WITH A WARMING TREND. WEAK RIDGING DEVELOPS ALOFT AND HEIGHTS BUILD TO 584 DM BY FRIDAY. TEMPS SHOULD WARM BACK INTO THE LOWER/MID 80S BY FRIDAY. 43 && .MARINE... AS A WEAK INLAND FRONTAL BOUNDARY NEARS THE COAST EARLY SUNDAY MORNING...TODAY'S ONSHORE FLOW WILL BECOME LIGHT AND VARIABLE THROUGH SUNDAY. THIS FRONT MAY WORK ITS WAY OFF THE COAST ENOUGH MONDAY TO TURN LIGHT AND VARIABLE BREEZES OFFSHORE. A REINFORCING CENTRAL PLAINS HIGH EXPANDING SOUTHWARD WILL PUSH A COLDER AND DRIER AIR MASS INTO THE OFFSHORE WATERS TUESDAY. THIS WILL BRIEFLY DRIVE NORTHERLY WINDS TO CAUTION LEVELS DURING THE AFTERNOON AND EVENING HOURS. HIGH PRESSURE RE-ESTABLISHING ITSELF OVER THE SOUTHEASTERN U.S. THURSDAY WILL INITIATE A RETURN FLOW. 31 && .PRELIMINARY POINT TEMPS/POPS...
