.SYNOPSIS...TROPICAL DEPRESSION 13 CONTINUES TO MEANDER SLOWLY IN
THE SOUTHWESTERN GULF WITH NO CHANGE IN INTENSITY. A MOIST AIRMASS
REMAINS IN PLACE MAINLY ALOFT FROM PACIFIC MOISTURE WHILE A PLUME
OF GULF MOISTURE APPEARS TO HAVE SHIFTED EASTWARD TO THE EAST OF
THE MISSISSIPPI RIVER PER LATEST IR/WV IMAGERY. A WEAK CANADIAN
COLD FRONT INTO NORTH TEXAS AND THE OZARKS SHOULD PROGRESS THROUGH
THE AREA...ASSISTED BY THE LOWER PRESSURE IN THE GULF.

SIMILAR TO TUESDAY, MOISTURE DISTRIBUTION SHOULD BE LIGHT BUT
WIDESPREAD AND AGAIN MAINLY AFTERNOON OWING TO THE LACK OF
FOCUSING MECHANISMS. WILL GO WITH MAINLY SHOWERS WITH A FEW
THUNDERSTORMS DUE TO A LACK OF UPPER LEVEL DIVERGENCE.

&&

.SHORT TERM...GFS HAS BEEN VERIFYING BETTER ON TEMPS/POPS HERE AT
LCH SO FAR IN SEPTEMBER. HELT TEMPS BELOW GUIDANCE TODAY DUE TO
THE POSSIBLITY OF RAIN COOLED AIR SIMILAR TO A COUPLE OF DAYS AGO.
STAYED CLOSE ON TEMPS FOR THURSDAY AS COOL ADVECTION IS BALANCED
OUT BY SUBSIDENCE.

.LONG TERM...THURSDAY THROUGH THE WEEKEND NOW LOOKS DRY AS THE COLD FRONT
LOSES DEFINITION YET FILTERS IN NOTICEABLY DRIER AIR ON THURSDAY.

PRESSURE DOMINATING OUR WEATHER AND GIVING US A PLEASANT WEEKEND.
THE FIRST WEEK INTO OCTOBER SHOULD STAY SEASONABLY DRY WITH HIGH
PRESSURE RIDGING IN FROM THE EAST COAST WHILE STRONG MID LATITUDE
UPPER TROFS REMAIN NORTH OF THE THE SOUTHERN PLAINS. INCREASING
MOISTURE FROM A SOUTHERLY FETCH SHOULD BRING RAIN CHANCES BACK
INTO THE FORECAST TOWARDS THE LATTER PORTION OF NEXT WEEK.

11-3.9 MICRON IMAGERY AND METARS. 15Z SHOULD SEE IMPROVEMENT TO
VFR CIGS WITH OCCASIONAL PERIODS OF MVFR CIG/VIS IN SHOWERS/TSTMS

.MARINE...THOSE VENTURING OFFSHORE WILL FIND CONDITIONS ROUGHER WITH
GRADIENT WINDS ABOUT TROPICAL DEPRESSION 13 AND SHOWERS/TSTMS
MAKING FOR A MORE CHALLENGING PERIOD. SEAS SHOULD ALSO BUILD ALONG
WITH TIDES DUE TO THE EASTERLY FETCH. LATE THURSDAY NIGHT
