AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
1210 AM CDT SUN MAR 23 2014

.DISCUSSION...
FOR 06Z TAF ISSUANCE.

&&

.AVIATION...
PRIMARY CHANGE TO THIS FORECAST PACKAGE IS THE ADDITION OF SHOWERS
IN THE NEAR TERM. REGIONAL 88DS SHOW SHOWERS DEVELOPING IN
VICINITY OF THE PRE-FRONTAL WIND SHIFT OVER NRN LA...THEN
ADDITIONAL COVERAGE NORTH OF THE PRIMARY FRONT OVER SRN AR/NRN LA.
ALL THIS SHOULD PUSH SWD WITH THE FRONT OVERNIGHT. A STORM OR TWO
IS POSSIBLE...AS NOTED CURRENTLY ON RADAR...BUT COVERAGE DOES NOT
LIKE WIDESPREAD ENOUGH ATTM TO WARRANT ANY MENTION IN THE TAFS.
BEYOND THAT STILL EXPECTING VLIFR AT KLCH/KBPT AND LIFR ELSEWHERE
AS CEILINGS AND/OR FOG DEVELOP TONIGHT. ONLY SLOW IMPROVEMENT
EXPECTED AFTER DAYBREAK...ALONG WITH STRENGTHENING NRLY WINDS
BEHIND THE FRONT.

.PREV DISCUSSION... /ISSUED 1004 PM CDT SAT MAR 22 2014/

UPDATE...EXPANDED DENSE FOG ADVISORY TO INCLUDE ALL OUR COASTAL
WATERS AS WELL AS THE INLAND LAKES AND BAYS. ALSO INTRODUCED
MENTION OF FOG INLAND UP TO THE I-10 CORRIDOR. VARIOUS MOS
SUGGESTING LESS FOG AND MORE OF A STRATUS...ELEVATED...SITUATION
OVERNIGHT. WILL CONTINUE TO MONITOR BUT WOULD NOT BE AT ALL
SURPRISED TO SEE STRATUS CRASH. OTHERWISE...RADAR DEPICTING LITTLE
ON RADAR AT THIS TIME...BUT WILL SEE AN INCREASE AS THE NIGHT
PROGRESSES WITH FRONTAL APPROACH.

MARCOTTE

FOR 00Z TAF ISSUANCE.

AVIATION...
NO SIGNIFICANT CHANGES TO PREVIOUS TAF THINKING. EXPECTING

PREV DISCUSSION... /ISSUED 358 PM CDT SAT MAR 22 2014/

DISCUSSION...A COLD FRONT IS CURRENTLY STRETCHED ROUGHLY A LITTLE
NORTH OF SHREVEPORT TO A LITTLE NORTH OF AUSTIN, TX WITH MOISTURE
GRADUALLY INCREASING OVER OUR LOCAL AREA. ALSO OF NOTE... A SUBTLE
TROUGH OR WARM FRONT IS ACROSS THE COASTAL WATERS FROM AROUND 60
NM SOUTH OF MARSH ISLAND TO NEAR HIGH ISLAND. DENSE SEA FOG IS
OCCURRING ALONG AND SOUTH OF THE GULF BOUNDARY. THE GULF BOUNDARY
WILL GRADUALLY LIFT NORTH AHEAD OF THE APPROACHING COLD FRONT THROUGH
THE REMAINDER OF THE AFTERNOON AND TONIGHT WITH SEA FOG PUSHING
INLAND.

TONIGHT AND SUNDAY MORNING THE COLD FRONT WILL MOVE INTO THE
REGION. INSTABILITY WILL BE FAIRLY LIMITED, HOWEVER STORMS WILL
BE POSSIBLE, ESPECIALLY ALONG THE FRONT AND AS A SOMEWHAT FAVORABLE JET
REGION LAYS OVER THE AREA. THE FRONT WILL PUSH INTO THE GULF
SUNDAY MORNING CLEARING OUT THE COASTAL FOG, HOWEVER MULTIPLE
DISTURBANCES WILL MOVE ACROSS THE REGION WHILE A SURFACE LOW
TRAVELS ACROSS THE NORTHERN GULF. ISENTROPIC LIFT WILL KEEP LIGHT
RAIN SHOWERS POSSIBLE INTO SUNDAY INTO MONDAY NIGHT BEFORE THE
FRONT MOVES AWAY AND A COOL DRY AIRMASS MOVES IN. BELOW NORMAL
TEMPS WILL MOVE IN MON AND TUE WITH WARMING BY WED NIGHT.

MARINE...SEA FOG CONTINUES TO CREEP NORTH ACROSS THE COASTAL
WATERS THIS AFTERNOON. A LARGE PORTION OF THE WATERS BEYOND 20 NM
HAVE A VIS OF 1 NM OR LESS. THIS IS ALSO OCCURRING FROM HIGH ISLAND
TO AROUND SABINE PASS AND OFF 20 NM AS A WEAK BOUNDARY SLOWLY
LIFTS NORTH. AS THE BOUNDARY LIFTS NORTH THE DENSE FOG ADV THAT IS
CURRENTLY IN EFFECT WILL LIKELY BE EXPANDED NORTH AND MAY
EVENTUALLY INCLUDE THE COASTAL LAKES AND BAYS.

A COLD FRONT WILL SWEEP THROUGH THE COASTAL WATERS SUNDAY MORNING
CLEARING OUT THE FOG AND INCREASING WINDS. MODERATE TO STRONG
NORTH WINDS WILL OCCUR FROM MID DAY SUNDAY THROUGH EARLY MONDAY
MORNING. AN SCA MAY NEED TO BE HOISTED FOR THAT PERIOD.

WINDS ARE EXPECTED TO RELAX SOMEWHAT MONDAY INTO TUESDAY MORNING,
HOWEVER AN AREA OF LOW PRESSURE WILL MOVE ACROSS THE NORTHERN GULF
MONDAY NIGHT AND TUESDAY WITH WINDS INCREASING AGAIN TUESDAY IN
THE WAKE OF THE LOW. WINDS WILL SLOWLY RELAX AGAIN DURING MID WEEK.
