.DISCUSSION...
POSITIONING OF HIGH PRES SYSTEMS INLAND AND LOWER PRES OVER BAY
OF CAMPECHE & SOUTHERN GULF WILL LEAD TO A PERSISTENT LOW LEVEL
E/NE FLOW ACROSS THE REGION THRU MOST OF THE WORK WEEK. MAY SEE
SOME ISOLATED PRECIP AROUND THE MATAGORDA BAY AREA TODAY AND
TUESDAY BUT OVERALL THIS SETUP WILL EFFECTIVELY WILL KEEP DEEPER
GULF MOISTURE OFFSHORE AND PROVIDE VAST MAJORITY OF SE TX WITH A
PLEASANT & DRY WEEK OF WX.

LONGER FETCH OF E/NE WINDS ACROSS THE GULF WILL HOWEVER RESULT IN
ELEVATED TIDE LEVELS. PROBABLY WON`T HAVE ANY SIGNIFICANT COASTAL
FLOOD ISSUES ALONG THE COAST, BUT WILL NEED TO KEEP AN EYE ON
THINGS TOWARD MIDWEEK NEAR TIMES OF HIGH TIDE WHEN ASTRONOMICAL
LEVELS ARE HIGHER.

UPPER LOW OVER NCNTL MEXICO EXPECTED TO FILL AND BE ABSORBED BY
THE NEXT TROF (NOW SITUATED OFF THE PACIFIC NW COAST) AS IT HEADS
INTO THE CNTL US TOWARD MIDWEEK. RIDGE SHOULD AMPLIFY BEHIND IT
ALLOWING TROF TO DIG SWD INTO THE THE E/SE STATES GOING INTO THE
WEEKEND. RESULTING NW/N FLOW ALOFT AND UPPER RIDGING SHOULD
PROVIDE CONTINUED DRY WX THRU THE WEEKEND. 47

&&

.MARINE...
WINDS/SEAS BEGINNING TO PICK UP OVER THE COASTAL WATERS THIS MORNING
(LIKELY IN RESPONSE TO THE TIGHTENING GRADIENT RELATED TO THE SYSTEM
DEVELOPING NEAR THE BAY OF CAMPECHE). TIDES ALSO APPEAR TO BE RESPON-
DING TO THIS INCREASED E/NELY FLOW WITH LEVELS CLOSE TO ONE FT ABOVE
NORMAL ATTM. CAUTION FLAGS MAY BE NEEDED OVER THE OFFSHORE WATERS BY
TONIGHT GIVEN THE CURRENT TRENDS. NOT A LOT OF CHANGES WITH THE OVER-
ALL PATTERN (OF MODERATE/STRONG NE/ELY WINDS) UNTIL LATE IN THE WEEK
AS THIS SYSTEM FINALLY MOVES OFF TO THE EAST. 41

&&

.AVIATION...
NOT TOO MANY CHANGES WITH THIS VFR FCST AS THE NE-ELY FLOW PERSISTS
THE NEXT FEW DAYS. WILL LIKELY KEEP A BRIEF MENTION OF PATCHY FG AT
THE USUAL SITES (LBX/CXO) FOR EARLY TUES MORNING. NOT TOO SURE WITH
THE POSSIBLE MENTION OF PCPN FOR GLS THIS MORNING GIVEN THE CURRENT
RADAR TRENDS...BUT WILL LIKELY LEAVE TAF DRY FOR NOW. THIS IDEA MAY
HAVE TO BE RECONSIDERED FOR TUES MORNING. 41
