AVIATION...  
SCT/BKN CLOUD LAYER FROM 2000-4000 FEET WILL CONTINUE TO PRODUCE  
INTERMITTENT MVFR/VFR CONDTIONS OVER THE NEXT SEVERAL HOURS BEFORE  
GIVING WAY TO PREDOMINATELY MVFR CONDITIONS. WINDS WILL ALSO  
REMAIN ELEVATED WITH SUSTAINED SPEEDS OF 20-25 KNOTS AND GUSTS TO  
30 KNOTS OVER THE NEXT SEVERAL HOURS. A BAND OF PREFRONTAL SHOWERS  
HAS DEVELOPED THIS EVENING AND COULD LEAD TO SOME -RA AT LCH AND  
BPT BETWEEN 00Z AND 02Z BUT SHOULD NOT YIELD ANY RESTRICTIONS. THE  
MAIN SQUALL LINE ACCOMPANIED BY GUSTY VARIABLE WINDS, TSRA, AND  
IFR VISIBILITY/CEILING RESTRICTIONS IS STILL FORECAST TO MOVE

PACKAGE STILL LOOKS TO BE ON TRACK BUT WILL BE AMMENDED IF

DISCUSSION...  
BREEZY DAY ACROSS THE AREA THIS AFTERNOON IN ADVANCE OF A STORM  
SYSTEM CURRENTLY APPROACHING WESTERN OKLAHOMA. A LINE OF SHOWERS  
AND THUNDERSTORMS ARE CURRENTLY DEVELOPING IN THE AREA OF ENHANCED  
LIFT FROM THE ARK-LA-TEX DOWN INTO SYSTEM TEXAS. HI-RES GUIDANCE  
CONTINUES TO MARCH THIS LINE TO THE EAST OVERNIGHT, BUT OVERALL  
TREND HAS SHOWN WEAKENING POTENTIAL ALONG THE SOUTHERN END FOR A  
TIME. THE GREATEST POTENTIAL FOR SEVERE THUNDERSTORMS CONTINUES TO  
BE ACROSS THE NORTHWESTERN COUNTIES AND PARISHES WHERE SPC HAS  
ENHANCED OUTLOOK. THAT SAID MOST OF THE AREA HAS SOME RISK OF  
SEVERE STORMS.  
 
THE LINE OF THUNDERSTORMS WILL CONTINUE THROUGH THE AREA OVERNIGHT  
AND WILL LIKELY STILL BE ONGOING ACROSS THE EASTERN PORTIONS OF  
THE FORECAST AREA TOMORROW MORNING BEFORE DRIER AIR FILTERS INTO  
THE REGION WITH A DRY WEATHER FORECAST INTO THE WEEKEND.  
 
ALSO HAD TO EXTEND THE WIND ADVISORY THROUGH THIS EVENING FOR THE  
IMMEDIATE COASTAL COUNTY AND PARISHES FOR CONTINUED BREEZY  
CONDITIONS.  
 
THE NEXT STORMS SYSTEM WILL APPROACH ON MONDAY, BUT IT DOES NOT  
LOOK AS STRONG AS THE ONE CURRENTLY MOVING THROUGH THE AREA.  
 
A STRONGER SYSTEM WILL MOVE THROUGH THURSDAY WITH THE CHANCE OF  
SHOWERS AND THUNDERSTORMS AND POSSIBLY SOME SEVERE STORMS.  
 
TEMPERATURES WILL CONTINUE TO BE ABOVE CLIMO.  
 
MARINE...  
WITH STRONG SOUTHERLY WINDS CONTINUING, HAD TO EXTEND THE SMALL  
CRAFT ADVISORY THROUGH AT LEAST THE OVERNIGHT HOURS. WINDS AND  
SEAS WILL CONTINUE TO REMAIN ELEVATED.
