PREV DISCUSSION... /ISSUED 513 AM CST SAT NOV 24 2012/

AVIATION...THE CLOUD DECK AT 4 TO 5 KFT CONTINUES TO CLEAR THE
AREA AND WILL DEPART THE KLFT AND KARA TERMINAL THROUGH THE NEXT 2
TO 3 HOURS. THE BRISK NORTH WIND WILL GRADUALLY EASE THROUGH
THE DAY AND GO CALM OVER NIGHT.

PREV DISCUSSION... /ISSUED 421 AM CST SAT NOV 24 2012/

DISCUSSION...
TEMPERATURES THIS MORNING VARIED GREATLY WITH MID 40S NORTH TO
LOW TO MID 50S SOUTH. HIGH LEVEL CLOUD COVER AND STRONGER WINDS
HAVE KEPT TEMPERATURES UP OVER THE SOUTHERN HALF OF THE AREA. THE
COLD FRONT WAS EXITING OUR LOUISIANA COASTAL WATERS.

NORTHERLY WINDS ALONG AND SOUTH OF THE I-10 CORRIDOR CONTINUED TO
REMAIN ELEVATED WITH WINDS OF 10 TO 15 MPH AND GUSTY. WFO LCH 88D
VAD WIND PROFILE SHOWED WINDS AROUND 25 KNOTS JUST ABOVE THE
SURFACE.

WINDS WILL BE TAPERING DOWN TOWARDS NOON TODAY AND CONTINUING TO
DECREASE THIS AFTERNOON. BOATERS WILL NEED TO KEEP IN MIND THAT A
SMALL CRAFT ADVISORY WILL BE IN EFFECT TODAY ENDING AROUND NOON.

TEMPERATURES WILL BE 10 TO 15 DEGREES COOLER TODAY ACROSS THE REGION
AS COOLER AIR FILTERS INTO AREA.

TONIGHT EXPECT LIGHT WINDS AND CLEAR SKIES TO PROVIDE GOOD
RADIATIONAL COOLING. MOST AREAS WILL REMAIN ABOVE FREEZING TOWARD
SUNDAY MORNING...HOWEVER...SOME AREAS IN CENTRAL LOUISIANA MAY
DROP TO THE LOWER 30S AS LONG AS SOUTHERLY FLOW DOESN'T RETURN TO
QUICKLY. GFS MODEL SHOWS THE SURFACE HIGH TONIGHT SHIFTING EAST BY
SUNDAY MORNING ALLOWING FOR WEAK SOUTHERLY RETURN. SINCE THE
FREEZE AFFECTED AREA LOOKS TO BE RATHER ISOLATED TO ONLY PARTS OF
CENTRAL LOUISIANA...WILL LET DAY SHIFT DECIDE WHETHER THERE SHOULD
BE A FREEZE WARNING TONIGHT ACROSS CENTRAL LOUISIANA OR NOT. GFS
MOS GUIDANCE IS RIGHT ON THE 32 DEGREE MARK FOR ALEXANDRIA
SATURDAY NIGHT SO WE WILL BE LOOKING AT THE NEXT GUIDANCE PACKAGE
FOR ADDITIONAL CHANGES THAT MAY SWAY FOR OR AGAINST A FREEZE
WARNING.

SOUTHERLY FLOW RETURNS ON SUNDAY AS THE UPPER LEVEL NORTHERLY FLOW
BREAKS DOWN AND A ZONAL WEST TO EAST FLOW DEVELOPS AHEAD OF THE
NEXT SYSTEM WHICH WILL BE MOVING INTO THE CENTRAL AND SOUTHERN
PLAINS ON MONDAY. INSTABILITY WILL BE HIGHER WITH THIS NEXT SYSTEM
MAINLY TO OUR NORTHWEST MONDAY AFTERNOON...NEVERTHELESS... WE
COULD SEE SOME STRONGER STORMS DEVELOP LATE IN THE AFTERNOON AND
CONTINUING INTO MONDAY NIGHT AS A STRONG JET WORKS FROM WEST TO
EAST ACROSS THE AREA.

A COLD FRONT WILL MOVE THROUGH THE AREA ON TUESDAY WITH RAPID
DRYING AND HIGH PRESSURE BUILDING BACK INTO THE REGION. STABLE CONDITIONS
WILL LAST ONLY THROUGH THURSDAY OF NEXT WEEK...THEN ANOTHER SHORT
SHORT WAVE WILL TRAVERSE OUR AREA ON FRIDAY. SO THIS FORECAST
PACKAGE BEGINS WITH MENTION OF A FRONT...THEN WE GET ANOTHER ON
TUESDAY OF NEXT WEEK...THEN END THE FORECAST PACKAGE ON FRIDAY
WITH MENTION OF RAIN.

MARINE...
SMALL CRAFT ADVISORY IN EFFECT THROUGH NOON AS BRISK NORTHERLY
WINDS CONTINUE OVER THE NORTHWEST GULF OF MEXICO. WINDS AND SEAS WILL
DIMINISH THIS AFTERNOON.
