.DISCUSSION...
NOT MUCH CHANGE OR REASONING TO THE ONGOING FCST. BASED ON RIG
OBSERVATIONS & SAT PIX IT APPEARS AXIS OF THE EASTERLY WAVE IN
THE GULF CURRENTLY EXTENDS GENERALLY FROM OFF THE SW LA COAST TO WELL
SOUTHWARD INTO THE GULF. LOCATIONS CLOSER TO THE COAST WILL BEGIN
TO SEE THE DEEPER TROPICAL MOISTURE & SCT PRECIP CHANCES ARRIVE
LATER TODAY AS THE AXIS MAKES CONTINUED WWD PROGRESS. ONCE WE GET
ON THE BACKSIDE OF THE TROF...DEEPER MOISTURE WILL GRADUALLY
SPREAD INLAND ON TUE AS LLVLS OF THE ATMOS OPEN BACK UP. CORRESPONDING
PRECIP CHANCES INCREASE FURTHER INLAND AS THIS OCCURS. IN ADDITION
TO GULF MOISTURE...WE SHOULD SEE SOME PACIFIC CONTRIBUTIONS OF
MOISTURE ASSOCIATED WITH HURRICANE ODILE AS IT RIDES UP AND OVER
RIDGE IN CNTL MEXICO AND EVENTUALLY OVER SE TX DURING THE TUE-THURS
TIME PERIOD. ANTICIPATE FAIRLY DECENT CHANCES OF PRECIP...MUCH OF
IT PROBABLY WELCOME. HIGHER TOTALS THRU THE WEEK WILL PROBABLY ALONG
& SOUTH OF I-10 WHERE DEEPER MOISTURE WILL RESIDE. CANNOT RULE OUT
SOME LOCALLY HEAVY TOTALS ELSEWHERE WITH CLUSTERING, ETC BUT DON`T
ANTICIPATE MUCH OF A WIDESPREAD ISSUE. PW VALUES AROUND 2" APPEAR
TO LINGER THRU NEXT WEEKEND SO SEE NO REASON TO EXCLUDE CONTINUED
SCT PRECIP CHANCES EACH DAY. AS TO WHEN THE NEXT FRONTAL BOUNDARY
ARRIVES: ECMWF SAYS AROUND SEPT 22...GFS LATER. 47

&&

.MARINE...
WINDS/SEAS OVER THE OFFSHORE WATERS HAVE DECREASED OVERNIGHT AND
HAVE LET THE SCEC EXPIRE. OTHERWISE WILL BE KEEPING WITH FCST OF
LIGHT E/NELY WINDS TODAY WITH THE DIRECTION BECOMING MORE E/SELY
TONIGHT/TUES. SPEEDS SHOULD PICK UP SOME DURING THE WEEK BUT NOT
ENOUGH FOR ANY CAUTION/ADVISORY FLAGS IS CURRENT THINKING. 41

&&

.AVIATION...
SPOTTY MVFR CIGS/VIS THIS MORNING SHOULD MIX OUT BY MID/LATE MORN-
ING. OTHERWISE VFR FOR THE AFTN. AS DWPTS SLOWLY RISE TONIGHT/EARLY
TUES MORNING WE COULD SEE A RETURN OF (MOSTLY) MVFR VIS/CIGS DURING
THE OVERNIGHT HOURS. 41
