GRADUALLY THICKEN AND LOWER DURING THE PERIOD AS WAA BEGINS TO

DURING THE DAY TOMORROW. WINDS COULD BECOME GUSTY NEAR THE COAST.

DECIDED TO HOLD OFF ON SHOWER MENTION IN THE TAFS AT THIS TIME.

DISCUSSION...
1039 MB SURFACE HIGH CENTERED OVER EASTERN KANSAS CONTINUES TO
RIDGE DOWN INTO THE FORECAST AREA PROVIDING A COLD AND DRY
CONTINENTAL AIR MASS TO THE REGION. HOWEVER...ACTIVE SOUTHWEST
FLOW ALOFT HAS BROUGHT EXTENSIVE UPPER LEVEL CLOUDS TO THE
FORECAST AREA...WHICH HAS HELPED KEEP AIR TEMPERATURES ABOUT 5
DEGREES HIGHER THAN FORECAST FROM YESTERDAY. THEREFORE...HAVE
TRIMMED BACK THE HARD FREEZE WARNING TO ONLY CENTRAL
LOUISIANA...AS THEY WILL STILL HAVE A CHANCE TO REACH THE MID 20S
FOR A FEW HOURS BEFORE TEMPERATURES START TO RISE AFTER SUNRISE.
DESPITE THE CLOUDS...STILL QUITE CHILLY WITH FREEZING LINE AS FAR
SOUTH AS ORANGE...NORTH LAKE CHARLES (CHENAULT KCWF)...AND NEW
IBERIA. WITH WINDS RUNNING AROUND 10 MPH...WIND CHILLS ARE IN THE
LOW TO MID 20S AREA WIDE.

WITH UPPER LEVEL CLOUDS HELPING TO FILTER FULL SUNSHINE...AND
SURFACE RIDGE SETTLING OVER THE REGION...WILL BE QUITE CHILLY
TODAY WITH HIGHS IN THE UPPER 40S TO AROUND 50.

AIR MASS WILL QUICKLY MODIFY LATER TONIGHT AND MONDAY AS SURFACE
RIDGE MOVES OFF TO THE EAST...AND SHORT WAVE OVER THE SOUTHWEST
U.S. MOVES QUICKLY TO THE EAST. THE RESULT WILL BE AN INCREASE IN
SOUTHERLY WINDS BRINGING A MORE MOIST...MODIFIED GULF AIR MASS
INTO THE FORECAST AREA. BY MONDAY AFTERNOON...PRECIPITABLE WATER
IS EXPECTED TO BE OVER 1.25 INCHES AND MEAN RH OVER 80 PERCENT.
WITH MODERATE LOW LEVEL CONVERGENCE AND FORCING...WIDESPREAD SHOWERS
WILL FORM FROM WEST TO EAST DURING THE DAY...WITH SOME
ISOLATED...MAINLY ELEVATED THUNDERSTORMS. WITH THE MODIFIED MARINE
LAYER EXPECTED IN PLACE...LOW LEVEL INSTABILITY WILL BE LACKING
OVER INLAND LOCATIONS. STILL...STRONG AND TURNING LOW LEVEL
JET...WILL CREATE VERY IMPRESSIVE SHEAR VALUES. THEREFORE...IF ANY
LOW LEVEL INSTABILITY CAN DEVELOP OR ANY OF THE SHOWERS CAN BECOME
ROOTED AT THE SURFACE...SOME STRONG WINDS OR EVEN ISOLATED
ROTATING CELLS CAN NOT BE RULED OUT DURING THE AFTERNOON INTO
EARLY EVENING HOURS. ALSO...SOME LOCALLY HEAVY RAINFALL...MAINLY
NEAR THE COAST...WILL BE POSSIBLE. THIS COMBINED WITH STRONG WINDS
HELPING TO CREATE WATER PILING AND ABOVE NORMAL TIDES ALONG THE
COAST...COULD POSE SOME WATER RISES IN THE LOWER
NECHES...CALCASIEU AND VERMILION BASINS.

SHOWER ACTIVITY WILL GRADUALLY FROM WEST TO EAST DURING MONDAY
NIGHT AS THE SHORT WAVE MOVES OFF TO THE EAST.

MILD AND MORE HUMID CONDITIONS WILL RETURN UNTIL A COLD FRONT MOVE
ACROSS THE FORECAST AREA LATE WEDNESDAY NIGHT AND EARLY THURSDAY
MORNING. AGAIN...A CHANCE OF SHOWERS AND THUNDERSTORMS WILL OCCUR
AHEAD OF THIS FRONT.

RUA

MARINE...
MSAS ANALYSIS AND RIG/BUOY OBSERVATIONS...SHOW SMALL CRAFT ADVISORY
CONDITIONS OCCURRING OVER THE COASTAL WATERS. THESE CONDITIONS
WILL GRADUALLY DIMINISH DURING THE AFTERNOON HOURS AS COLD AIR
ADVECTION WANES AS THE INFLUENCE OF THE SURFACE HIGH WEAKENS.

WINDS WILL QUICKLY COME BACK AROUND TO A SOUTHERLY DIRECTION LATE
TONIGHT INTO MONDAY AS THE HIGH CONTINUES TO MOVE OFF TO THE EAST.
SURFACE WAVE MOVING WITH THE UPPER LEVEL DISTURBANCE FROM THE
WEST...WILL HELP INCREASE WIND SPEEDS OVER THE COASTAL
WATERS...WITH SMALL CRAFT ADVISORY CONDITIONS AGAIN POSSIBLE ON
MONDAY. TIDE GUIDANCE STILL SHOWS TIDES AROUND ONE FOOT ABOVE
PREDICTED LEVELS BY MONDAY AFTERNOON...WHICH COULD PUSH ACTUAL
TIDE LEVEL TO NEAR 3 FEET MLLW AT SABINE PASS AND CALCASIEU PASS
DURING HIGH TIDE. THIS SYSTEM WILL ALSO BRING WIDESPREAD SHOWERS
AND ISOLATED THUNDERSTORMS.

WINDS AND SEAS WILL DECREASE ON TUESDAY AS THIS DISTURBANCE MOVES
