AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BROWNSVILLE TX 145 PM CDT THU AUG 14 2008 .DISCUSSION...DEEP MOISTURE COULD GIVE DEEP SOUTH TEXAS A GOOD CHANCE FOR SCATTERED SHOWERS OR THUNDERSTORMS DURING THE DAYTIME HOURS THROUGH THE END OF THE WEEK. BRO SOUNDING THIS MORNING SHOWED A PRECIP WATER OF 2.23 AND A K-INDEX OF 32. HIGH PRESSURE BOTH SURFACE AND ALOFT WILL DOMINATE THE AREA FOR THE WEEKEND CAUSING A RELATIVELY DRY AND STABLE AIRMASS TO DEEP SOUTH TEXAS FROM THE WEEKEND THROUGH THE MIDDLE OF NEXT WEEK. WINDS WILL BE LIGHT TO MODERATE FROM THE SOUTHEAST THROUGH THE WEEKEND. BOUNDARY LAYER RELATIVE HUMIDITIES SHOWED ABOVE 50 PERCENT ALL THE WAY UP TO 500 MB THROUGH TONIGHT THEN DRYING OUT SOME ON FRIDAY. && .MARINE...FOR THE NEXT SEVERAL DAYS INCLUDING THE WEEKEND...GENERALLY BENIGN CONDITIONS WILL PREVAIL FOR THE GULF WATERS AS THE INITIAL TROUGH OF LOW PRESSURE EXTENDING INTO THE WATERS (AND PARTLY ASSOCIATED WITH WEAK UPPER LEVEL DISTURBANCES WHICH ARE HELPING TO KICK OFF THE SCATTERED TO NUMEROUS PRECIPITATION COVERAGE OVER LAND) CONTINUES INTO FRIDAY...THEN GRADUALLY RETREATS TO ITS MORE QUASI-PERMANENT POSITION ACROSS THE RIO GRANDE HIGHLANDS OF NORTHERN MEXICO INTO WEST TEXAS OVER THE WEEKEND. EVEN STILL...THE GRADIENT WILL ONLY GRADUALLY INCREASE ESPECIALLY SATURDAY NIGHT INTO SUNDAY NIGHT...SO THE INCREASE IN WINDS AND SEAS WILL BE SLOW. OUTSIDE OF ANY PRECIPITATION...WHICH APPEARS TO HAVE BEST CHANCES THIS EVENING/OVERNIGHT AND AGAIN SUNDAY NIGHT INTO MONDAY IF THE 12Z GFS IS TRENDING CORRECTLY...BOATING CONDITIONS LOOK RATHER FAVORABLE INTO THE WEEKEND. SUNDAY NIGHT THROUGH TUESDAY THE GRADIENT TIGHTENS A BIT MORE AS THE SURFACE TROUGH IN WEST TEXAS DEEPENS SOMEWHAT. THIS SHOULD PUSH WINDS INTO THE CAUTION RANGE ACROSS THE GULF MAINLY DURING THE OVERNIGHT HOURS...AND BUILD SEAS PERHAPS TO 5 FEET IN SOME AREAS. ACROSS THE LAGUNA...AFTERNOON WINDS MAY GUST TOWARD 18-20 KNOTS SATURDAY AND SUNDAY PRODUCING A PERIOD OF MODERATE CHOP...OTHERWISE LIGHTER WINDS OF 10 KNOTS OR LESS AND A LIGHT CHOP ARE EXPECTED THROUGH SUNDAY. A BIT MORE WIND CONTINUING INTO THE EVENING SUNDAY THROUGH TUESDAY MAY KEEP THE MODERATE CHOP GOING A BIT LONGER. && .AVIATION...AS EXPECTED...THUNDERSTORMS ARE RAPIDLY DEVELOPING EARLY THIS AFTERNOON JUST ABOUT EVERYWHERE FROM BROOKS AND HIDALGO COUNTIES EAST TOWARD THE COAST. GIVEN THE INSTABILITY...LACK OF A CAP...OLD DIFFERENTIAL HEATING BOUNDARIES...AND DEEP LAYER MOISTURE (PRECIPITABLE WATER NEAR 2.2 INCHES)...SAW NO REASON TO GET CUTE AND HAVE INCLUDED TEMPO TSRA WITH IFR VISIBILITY AND MVFR CEILING. OBVIOUSLY...A CELL SITTING ON TOP OF ONE OF THE TERMINALS MAY WELL DROP VISIBILITY BELOW 1 MILE BUT WILL AMEND AS NECESSARY SHOULD THAT OCCUR. WITHOUT A SOLIDLY MOVING OUTFLOW...EXPECT WIND GUSTS TO HOLD IN THE 25 KNOT RANGE AND HAVE GONE WITH THE OBLIGATORY VRB15G25 KNOTS FOR NOW. WITH THE EARLY START...CONDITIONS SHOULD IMPROVE AROUND SUNSET...BUT THERE MAY BE SOME DEBRIS RAIN AND MID CLOUDS WHICH ARE NOT ACCOUNTED FOR AFTER 00Z...YET. OTHERWISE...EXPECT CIRRUS TO BE LAST TO CLEAR BUT WITH RAIN ON THE GROUND AND LIGHT WINDS FOG COULD BE A POSSIBILITY...AS WELL AS SOME AREAS OF LOW CLOUDS. FOR NOW...HAVE JUST ROLLED 3-4 MILE TEMPO IN BR ALONG WITH SCATTERED NEAR-IFR CLOUDS AND WILL LET NEXT SHIFT(S) HONE IN ON THE DETAILS.
