AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
705 AM CST SAT JAN 3 2009

.AVIATION...MAIN ISSUES FOR THE TAFS THIS MORNING PERTAIN TO
TIMING OF CONVECTION AND ONSET OF STRONGER SRLY WINDS. 1ST OFF
MOST OF THE TAF SITES...ESPECIALLY THE 4 SRN SITES...HAVE SEEN
VERY LOW CEILINGS ALL NIGHT LONG WITH STRONGER WINDS ALOFT
PRODUCING A GOOD STRATUS DECK. HOWEVER THIS DECK HAS BEEN BREAKING
UP WITH KLCH AND KARA BOTH NOW VFR. EXPECT CEILINGS TO CLIMB WITH
SUNRISE...LEAVING THE AREA EITHER MVFR OR POSSIBLY EVEN VFR PRIOR
TO PRECIP DEVELOPMENT. EXPECT CONVECTION TO DEVELOP OVER THE NWRN
GULF OFF THE TX COAST OR OVER THE HOUSTON METRO AREA BY MID-
MORNING THEN SPREAD ENE OVER THE FORECAST AREA THEREAFTER. ATTM
ELECTED TO CARRY JUST PREVAILING SHOWERS WITH TEMPO THUNDER AS
FORECAST SOUNDINGS CONTINUE TO INDICATE LIMITED SFC-BASED
INSTABILITY. IF THUNDER BECOMES MORE PREVALENT THE TAFS CAN BE
AMENDED AT THAT TIME. EXPECT STRONGER SRLY WINDS TO DEVELOP PRIOR
TO NOON AS THE PRESSURE GRADIENT AHEAD OF THE APPROACHING STORM
SYSTEM TIGHTENS OVER THE AREA. ONCE THE PRECIP PASSES THE
AREA...EXPECT BRIEF IMPROVING CONDITIONS BEFORE LOWER CEILINGS AND
VISIBILITIES RETURN AFTER SUNSET.

.PREV DISCUSSION... /ISSUED 349 AM CST SAT JAN 3 2009/

DISCUSSION...IT IS A WARM NIGHT ACROSS THE REGION WITH TEMPERATURES IN THE
LOWERS 70S TO THE MID 60S AS MOISTURE CONTINUES TO INCREASE IN
ADVANCE OF POTENT SOUTHERN STREAM VORT MAX AND ITS ASSOCIATED
SPEED MAX THAT CAN CLEARLY BE SEEN MOVING ACROSS SOUTH CENTRAL
TEXAS THIS MORNING. SHOWERS AND THUNDERSTORMS WILL BEGIN TO
DEVELOP ACROSS SOUTHEAST TEXAS AND ADJACENT COASTAL WATERS WITHIN
THE NEXT COUPLE OF HOURS. THIS ACTIVITY WILL MOVE TO THE NORTHEAST
ACROSS THE REGION THIS MORNING INTO THE AFTERNOON. AM RELUCTANT TO
LEAVE THE SEVERE WORDING IN THE ZONES DUE TO THE LOW
PROBABILITY...HOWEVER BEING IT IS ALREADY THERE WILL MAINTAIN.
THERE WILL BE EXCELLENT SHEAR PROFILE...HOWEVER AM THE BIGGEST
LIMITING FACTOR FOR SEVERE WILL BE MINIMAL HEATING AND MARINE
LAYER TO KEEP STORMS ELEVATED FOR THE MOST PART. GREATEST SEVERE
THREAT WILL BE FROM HAIL AND PERHAPS DAMAGING WINDS OR TORNADO IF
STORMS CAN ROOT INTO THE BOUNDARY LAYER.

WILL SEE CLEARING THIS EVENING INTO THE OVERNIGHT AND WITH THE
LIGHT WINDS AND PLENTY OF MOISTURE...WILL LIKELY SEE FOG...SOME OF
WHICH COULD BE RATHER DENSE ALONG AND SOUTH OF I-10.

ON SUNDAY A FRONT WILL BE WORKING INTO THE REGION IN THE
AFTERNOON. THERE COULD BE A FEW SHOWERS DEVELOP ALONG THE
FRONT...STILL LOWERED THE POPS AS CHANCES FOR MEASURABLE RAIN
LOOK LIMITED. ALSO INDICATIONS ARE THAT WE WILL SEE SOME GOOD
WARMING AHEAD OF THE FRONT...ESPECIALLY ACROSS SOUTH CENTRAL
LOUISIANA. RECORDS LOOK TO HOLD FOR NOW AS THEY ARE IN THE LOWER
TO MID 80S.

THE FRONT WILL CONTINUE MOVE SOUTH TO THE COASTAL WATERS TOMORROW
NIGHT. MEANWHILE A TROUGH WILL BE DIGGING OUT ACROSS THE
SOUTHWESTERN PORTION OF THE U.S. WILL SEE SEVERAL DISTURBANCES
EMANATE FROM THIS SYSTEM AS IT MOVES TO THE EAST AND THESE
DISTURBANCES WILL PROVIDE A QUITE A BIT OF ISENTROPIC UPGLIDE OVER
THE COOLER AIR AT THE SURFACE TO PRODUCE QUITE A BIT OF RAIN WITH
A FEW EMBEDDED THUNDERSTORMS. THIS ACTIVITY IS EXPECTED TO BEGIN
MONDAY AND CONTINUE THROUGH TUESDAY. A WAVE IS FORECAST TO DEVELOP ACROSS
THE COASTAL WATERS AND PERHAPS THE EXTREME SOUTHEASTERN PORTION OF
THE FORECAST AREA EARLY TUESDAY MORNING AIDING SOME NORTHWARD
MOVEMENT OF THE FRONT. STILL THE COLDER AIR USUALLY WINS IN THESE
SITUATIONS AND WILL BE CUTTING GUIDANCE HIGHS SEVERAL DEGREES AND
STILL MAY NOT BE COOL ENOUGH ACROSS THE NORTH AND WESTERN PORTIONS
OF THE FORECAST AREA ON MONDAY AND ALSO UNDERCUT GUIDANCE FOR
TUESDAY AS WELL...HOWEVER EXPECT THAT THESE TOO WILL HAVE TO BE
TRIMMED DOWN LATTER. COULD BE A GOOD RAINFALL EVENT WITH 1 TO 3
INCHES POSSIBLE FOR MUCH OF THE AREA WITH ISOLATED AMOUNTS OF UP
TO 5 NOT OUT OF THE QUESTION.

AS THE TROUGH PASSES TUESDAY NIGHT...THE AREA WILL BEGIN TO DRY
OUT AND EXPECT LITTLE TO NO CHANCE OF RAIN UNTIL PERHAPS NEXT
WEEKEND.

MARINE...SHOWERS AND THUNDERSTORMS WILL BE LIKELY ACROSS THE
COASTAL WATERS TODAY AS A DISTURBANCE PASSES THROUGH THE SOUTHERN
PORTION OF THE U.S. WILL CONTINUE THE FOG ADVISORY FOR THE COASTAL
WATERS THIS MORNING AS DEW POINTS ARE EXCEEDING WATER
TEMPERATURES. MIXING SHOULD DISSIPATE THE FOG BY AROUND 6 AM. MAY
HAVE TO CONTEND WITH FOG TONIGHT IN THE WAKE OF THE SYSTEM. A COLD
FRONT WILL MOVE INTO THE COASTAL WATERS TOMORROW NIGHT AND WILL
CAUSE AN EXTENDED PERIOD OF UNSETTLED WEATHER THROUGH TUESDAY
NIGHT. WINDS AND SEAS WILL BE INCREASING CONSIDERABLY ON TUESDAY
IN THE WAKE OF A LOW PRESSURE SYSTEM THAT WILL BE MOVING ALONG THE
FRONT TUESDAY. MAY NEED SOME HEADLINES FOR THIS IN FUTURE
FORECASTS.
