WATER VAPOR IMAGERY NICELY DEPICTING THIS SWATH OF DRY AIR FROM CENTRAL TEXAS EAST INTO LOUISIANA...SATELLITE DERIVED VALUES DIPPING BELOW 2 INCH PWATS. TODAY AND WEDNESDAY'S AREAL PRECIPITABLE COVERAGE OF NO MORE THAN 20-30% IS FORECAST BASED UPON THE STATIC NATURE OF THIS MORNING'S DRIER AND (SLIGHTLY) MORE STABLE PATTERN...ALONG WITH NO UPPER LEVEL SUPPORT WITHIN ANTI- CYCLONIC FLOW. THE MAIN WEATHER STORY THIS WEEK WILL BE THE ARRIVAL OF A FRIDAY/SATURDAY COLD FRONTAL. ALTHOUGH RECENT MODEL RUNS HAVE WAVERED IN THE CONFIDENCE OF THE TIMING AND STRENGTH OF THIS BOUNDARY...IT IS STILL FORECAST TO MAKE A SOUTHEASTERN TEXAS ENTRANCE LATE FRIDAY INTO EARLY SATURDAY. QUITE THE TROUGH DIGGING INTO THE PACIFIC NORTHWEST BUT IT WILL ENCOUNTER SOUTHERN PLAINS FLATTENED RIDGING. THE BACKING AIR MASS WILL BE FAIRLY COLD AND DRY FOR THIS TIME OF YEAR...BUT LATEST NWP MODELING KEEPS THE COLDEST AIR OFF TO THE NORTH AND EAST WITH AN ANTICIPATED MILDER TURN TO WEEKEND WEATHER.

AS OF NOW...GRIDS REFLECT LOW TO MODERATE CONFIDENCE OF FRIDAY AND SATURDAY PRECIPITATION. THE MAIN QUESTION WILL BE IF WE ARE FACING A HIGH RAINFALL EVENT GOING INTO THE WEEKEND. DOMINANT EASTERLY FLOW THROUGH EARLY NEXT WEEK MAY STEER EASTERN-BASED SHORTWAVE DISTURBANCES INTO AN ALREADY UNSETTLED AND HIGHLY MOIST UPPER TEXAS COASTAL ENVIRONMENT. THEREFORE... SLIGHT CHANCE COASTAL COUNTY AND MARITIME POPS WILL REMAIN AS BOOKMARKS TO ACCOUNT FOR THIS GENERALLY LOWER PRESSURE/UNSETTLED GULF OF MEXICO PATTERN. 31 && .PRELIMINARY POINT TEMPS/POPS...
