AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
1148 PM CST FRI MAR 4 2011

.AVIATION...
VFR CONDITIONS REPORTED AT KLCH AND KAEX WHILE KBPT WAS BEGINNING
TO SEE MVFR FOG DEVELOPING AND KLFT AND KARA WERE SHOWING CIGS
VARYING BETWEEN MVFR/IFR. EXPECT TO SEE LOWER CIGS CONTINUE TO
DEVELOP AT TAF SITES TONIGHT...BECOMING MOSTLY IFR BY 09Z...WITH
MVFR MORE LIKELY AT KAEX. FOG WILL ALSO BE POSSIBLE WITH VISBYS
2-4 SM. A FEW SHOWERS WILL DEVELOP OVERNIGHT...WITH SCATTERED
SHOWERS AND THUNDERSTORMS EXPECTED ALONG AND JUST AHEAD OF A COLD
FRONT DURING THE MORNING HOURS. FRONT WILL CROSS THE AREA BETWEEN
12Z-18Z...WITH WINDS SHIFTING TO THE NW AND BECOMING GUSTY IN THE
AFTN. EXPECT CIGS TO PERSIST...BUT GRADUALLY LIFT THROUGH THE AFTN
HOURS. 24

&&

.PREV DISCUSSION... /ISSUED 914 PM CST FRI MAR 4 2011/

UPDATE...
A FEW SPRINKLES OVER SE TX LAKE REGION WITH STORMS CONTINUING
OVER SE LA WITH ONE LCTN RPTG 6.1 INCHES. AS FOR SE TX AND SRN LA
AREAS OF FOG OVER THE COASTAL WATERS TONIGHT WITH LIGHT RAIN. THE
LATEST COLD FRONT LOOKS TO BE HERE AROUND NOON FOR LCH AND BPT AND
ABOUT 1 TO 2 FOR LFT AND ARA. STORMS WILL DEVELOP OUT AHEAD OF THE
FRONT TMRW MRNG TAPERING OFF BEHIND THE FRONT. CURRENT ZONES LOOK
FINE.

PREV DISCUSSION... /ISSUED 547 PM CST FRI MAR 4 2011/

AVIATION...
MOSTLY VFR CONDITIONS NOTED ACRS THE AREA LATE THIS AFTN. EXPECT
AN INCREASE IN LOW CLOUDS THIS EVENING AS MOIST SRLY LOW LEVEL
FLOW CONTINUES. CIGS TO LOWER TO IFR THROUGH MIDNIGHT WITH FOG
REDUCING VISBYS TO MVFR. WILL BEGIN TO SEE A FEW SHOWERS DEVELOP
OVERNIGHT AS LIFT INCREASES AHEAD OF A COLD FRONT. THE FRONT WILL
MOVE THROUGH THE AREA SATURDAY MORNING...WITH WINDS SHIFTING TO
THE NW IN ITS WAKE. EXPECT CIGS TO PERSIST...BUT GRADUALLY LIFT
THROUGH THE AFTN HOURS.

PREV DISCUSSION... /ISSUED 304 PM CST FRI MAR 4 2011/

DISCUSSION...
ANOTHER WARM AND HUMID SPRING LIKE DAY ACROSS THE FORECAST AREA AS
GRADIENT BETWEEN HIGH PRESSURE OVER THE SOUTHEAST U.S. AND LOWER
PRESSURE OVER THE PLAINS...ALLOWS FOR SOUTHERLY BREEZES OFF THE
GULF OF MEXICO. A FEW LIGHT SHOWERS UNDER THE CAP HAVE DEVELOPED
OFF AND ON IN THE WARM AIR ADVECTION REGIME...WITH ANY PRECIP ON
THE LIGHT SIDE.

SHORT WAVE WILL CONTINUE TO MOVE OUT OF THE ROCKIES AND EASTWARD
ACROSS THE MIDDLE PART OF THE COUNTRY THROUGH SATURDAY AND TO THE
EAST COAST BY SUNDAY. AHEAD OF THIS SYSTEM...MOISTURE WILL
CONTINUE TO INCREASE AS BOUNDARY LAYER SOUTHERLY WINDS INCREASE.
EXPECT PRECIPITABLE WATER VALUES TO BE BETWEEN 1.25 AND 1.50
INCHES WITH MEAN RH OVER 75 PERCENT DURING THE DAY ON SATURDAY. AS
THE SHORT WAVE MOVES ACROSS...IT WILL PUSH A SURFACE COLD FRONT
THROUGH THE FORECAST AREA. MODERATE LOW LEVEL FORCING AND MOISTURE
CONVERGENCE IS NOTED ALONG THE FRONT...SO THIS SHOULD BE ENOUGH TO
HELP LIFT THE MOISTURE INTO NUMEROUS SHOWERS. LOW LEVEL
INSTABILITY STILL LOOKS TO BE DECENT ENOUGH FOR A FEW
THUNDERSTORMS.

SHOWER ACTIVITY SHOULD INCREASE DURING THE OVERNIGHT AS SHORT WAVE
APPROACHES...WITH THE BEST LIKELIHOOD OF RAIN ON SATURDAY...A FEW
HOURS AHEAD...AND UNTIL JUST AFTER FRONTAL PASSAGE. AT THE
PRESENT...IT LOOKS LIKE FRONT SHOULD ENTER WESTERN PORTIONS OF THE
FORECAST AREA AROUND 9 AM...MOVE TO NEAR KAEX-KLCH BY NOON...AND
THE KLFT AREA BY 3 PM. THE BEST SCENARIO FOR ANY STRONG STORMS
WILL BE MID TO LATE AFTERNOON OVER FAR EASTERN ZONES...IF FRONTAL
WAVE DEVELOPS AS PROGGED...THAT WILL HELP INCREASE LOW LEVEL SHEAR
DURING MAX HEATING...ALTHOUGH THE BEST CHANCE FOR THIS TO HAPPEN
SEEMS TO BE JUST EAST OF THE FORECAST AREA. RAINS WILL GRADUALLY
TAPER OFF A FEW HOURS AFTER FRONTAL PASSAGE...WITH RAINS ENDING BY
EARLY EVENING OVER ACADIANA. QFP VALUES FOR THE DAY ON SATURDAY
AVERAGE BETWEEN 1/2 AND 1 INCH...WITH THE HIGHER AMOUNTS ALONG THE
SOUTHERN AND EASTERN AREAS.

HIGH PRESSURE BUILDING IN WILL BRING DRIER AND COOLER CONDITIONS
ON SATURDAY NIGHT...WITH A NICE END TO THE WEEKEND ON SUNDAY.

STILL LOOKS LIKE SOUTHERLY FLOW GRADUALLY RETURNS BY LATE MONDAY
AND INCREASES ON TUESDAY (MARDI GRAS) AS NEXT SYSTEM BEGINS TO
FORM OVER THE PLAINS. MARDI GRAS LOOKS TO BE WARM AND
BREEZY...WITH A FEW PASSING LIGHT SHOWERS.

THE NEXT...RATHER STRONG...COLD FRONT...IS SCHEDULED FOR WEDNESDAY
WITH A ROUND OF SHOWERS AND THUNDERSTORMS.

RUA

MARINE...
MODERATE SOUTHERLY WINDS WILL CONTINUE THROUGH THE NIGHT INTO
EARLY SATURDAY AS A COLD FRONT APPROACHES THE NORTHWEST GULF. MID
60S DEW POINTS ADVECTING OVER COOLER NEAR SHORE WATERS WILL AGAIN
PROVIDE THE POTENTIAL FOR LOW STRATUS AND SEA FOG DURING THE
EVENING HOURS INTO THE OVERNIGHT. INCREASING BOUNDARY LAYER WINDS ABOVE THE
SURFACE AND LIFT FROM APPROACHING SHORT WAVE MAY KEEP DENSE SEA FOG
PATCHY IN NATURE...THEREFORE WILL HOLD OFF ON ANY MARINE DENSE
FOG ADVISORY AT THIS TIME.

A COLD FRONT WILL ENTER THE SOUTHEAST TEXAS COASTAL WATERS BEFORE
NOON...AND EXIT THE SOUTH CENTRAL LOUISIANA COASTAL WATERS AROUND
6 PM. NUMEROUS SHOWERS AND A FEW THUNDERSTORMS ARE EXPECTED TO
DEVELOP AHEAD OF THE FRONT. BEHIND THE FRONT...WINDS WILL TURN TO
A NORTHWEST AND NORTH DIRECTION AND BECOME STRONG...WITH THE
LIKELIHOOD OF SMALL CRAFT ADVISORY CONDITIONS BY LATE TOMORROW
AFTERNOON INTO SATURDAY NIGHT.

WINDS WILL BEGIN TO DECREASE DURING THE DAY ON SUNDAY AS HIGH
PRESSURE QUICKLY BUILDS IN.

RETURN FLOW OFF THE GULF IS THEN EXPECTED TO DEVELOP ON MONDAY AND
INCREASE ON TUESDAY AS THE NEXT STORM SYSTEM BEGINS TO FORM OVER
THE CENTRAL PART OF THE COUNTRY.
