DISCUSSION...
A VERY SHARP CANADIAN COLD FRONT IS MOVING ACROSS THE FORECAST
AREA THIS EARLY MORNING AND AS OF 10/09Z WAS LOCATED FROM EAST OF
ALEXANDRIA TO BEAUMONT. A SOLID BAND OF SHOWERS AND THUNDERSTORMS
ARE MOVING AHEAD OF THE FRONT. A FEW OF THE STORMS ARE STRONG AND
SHOWING BOW SEGMENTS...WHICH COULD PRODUCE WIND GUSTS OVER 40 MPH.
FREQUENT CLOUD TO GROUND LIGHTNING AND BRIEF HEAVY RAINFALL WILL
ALSO ACCOMPANY THE STORMS. BEHIND THE FRONT...TEMPERATURES DROP
QUICKLY SOME 10F TO 15F DEGREES WITH BRISK NORTH WINDS. ALSO...ELEVATED
SHOWER ACTIVITY CONTINUES BEHIND THE FRONT.

THE COLD FRONT WILL CONTINUE TO MAKE STEADY PROGRESS TO THE
SOUTHEAST AND REACH ACADIANA AROUND 6 AM AND AT THE START OF THE
FORECAST PERIOD AND THROUGH LOWER ACADIANA AROUND 9 AM. THE
HEAVIEST RAINFALL WILL OCCUR ALONG AND JUST AHEAD OF THE FRONT
WITH GUSTY WINDS AND FREQUENT LIGHTNING THE MAIN HAZARDS. DECENT
LIFT AHEAD OF THE MAIN UPPER LEVEL TROF AXIS WILL KEEP OVER-
RUNNING CLOUDS AND SCATTERED ELEVATED SHOWERS BEHIND THE FRONT
THAT WILL GRADUALLY END FROM WEST TO EAST DURING THE AFTERNOON
HOURS. BRISK NORTH WINDS BRINGING GOOD COLD AIR ADVECTION AND THE
LACK OF SUNSHINE WILL MAKE FOR CHILLY CONDITIONS WITH HIGH
TEMPERATURES LIKELY REACHED DURING THE MORNING HOURS WITH THE
FRONTAL PASSAGE.

SURFACE RIDGE FROM THE PLAINS WILL SETTLE OVER THE FORECAST AREA
TONIGHT INTO WEDNESDAY. THIS WILL KEEP CHILLY CONDITIONS AROUND
FOR A FEW DAYS. A LIGHT FREEZE IS LIKELY TONIGHT ACROSS NORTHERN
ZONES...MAINLY HIGHWAY 190 CORRIDOR AND TO THE NORTH...WITH A LIGHT
FREEZE POSSIBLE ON TUESDAY NIGHT INTO WEDNESDAY MORNING FOR AREAS
NEAR AND NORTH OF INTERSTATE 10.

TEMPERATURES WILL SLOWLY MODERATE ON WEDNESDAY NIGHT INTO THURSDAY
AS THE SURFACE RIDGE MOVES OFF TO THE EAST.

A CHANCE FOR SHOWERS WILL RETURN FOR FRIDAY NIGHT INTO SATURDAY AS
MOISTURE RETURN WILL BUILD-UP BEFORE THE NEXT FRONTAL
PASSAGE...THAT IS EXPECTED LATE SATURDAY.

MARINE...
A STRONG CANADIAN COLD FRONT WILL MOVE ACROSS THE COASTAL WATERS
THIS MORNING. GOOD COLD AIR ADVECTION IS NOTED BEHIND THE FRONT
AND THIS SHOULD ALLOW FOR MIXING OVER THE RELATIVELY WARMER GULF
WATERS WITH BLUSTERY NORTH WINDS AND BUILDING SEAS THE RESULT. A
SMALL CRAFT ADVISORY WILL BE IN EFFECT FOR ALL MARINE ZONES
THROUGH THE AFTERNOON...WITH SMALL CRAFT ADVISORY CONTINUING INTO
THE NIGHT FOR THE NEAR AND OFFSHORE WATERS.

WINDS WILL SUBSIDE SLIGHTLY ON TUESDAY AS THE HIGH PRESSURE FROM
THE PLAINS SETTLES OVER THE REGION AND RELAXES THE GRADIENT.

SURFACE HIGH MOVES OFF TO THE EAST.
