1212 PM CST MON DEC 24 2012

.AVIATION...A WEAK COLD FRONT IS NEARLY THROUGH THE AREA AND IS
FILTERING IN DRIER AIR WITH VFR CONDITIONS. WINDS SHOULD DIMINISH DURING
THE AFTERNOON. MVFR CIGS RETURN LATE THIS AFTERNOON FOR LCH AND THIS
EVENING FOR BPT AS THE BOUNDARY LIFTS NORTH AS A WARM FRONT.

THE POLAR JET WHICH HAS BEEN NEARBY FOR SEVERAL DAYS BECOMES
QUITE ACTIVE LATE TONIGHT WITH AN ASSOCIATED FRONTAL WAVE IN EAST
TEXAS DRAGGING ACROSS NORTHERN LOUISIANA ON CHRISTMAS AND PUTTING
THE AREA IN A FAVORABLE WARM SECTOR FOR SEVERE TSTMS.

MVFR CIGS WITH TSTMS. WILL GO WITH PREDOMINANT MVFR CONDITIONS AND
GUSTY WINDS IN THE TAFS AFTER DAYBREAK. DAMAGING WINDS AND

UPDATE...
WEAK FRONTAL SYSTEM MOVING SLOWLY TOWARD THE I-10 CORRIDOR. MIGHT
BE ENOUGH MOISTURE TO SQUEEZE OUT A SHOWER OR TWO NEAR THE COAST
AND OVER THE COASTAL WATERS...ALTHOUGH WATER VAPOR SHOWS UPPER
LEVEL DISTURBANCE DEPARTING THE REGION SHORTLY AND THIS SHOULD
HELP LIMIT DEVELOPMENT FOR THE REMAINDER OF THE AFTERNOON.
ADJUSTED POPS AND WINDS ACCORDINGLY WITH THE FRONTAL MOVEMENT AS
IT STALLS NEAR THE COAST.

MAIN EVENT IS SCHEDULED FOR LATER TONIGHT AND INTO THE DAY ON
CHRISTMAS AND WILL TAKE ANOTHER CLOSE LOOK AT THIS WITH THE

DISCUSSION...
A COLD FRONT IS PUSHING THROUGH CENTRAL TEXAS AND NORTHWEST
LOUISIANA THIS MORNING. TEMPERATURES AHEAD OF THE FRONT ARE
RUNNING IN THE LOWER 60S DROPPING INTO 40S BEHIND THE FRONT. A FEW
SHOWERS CONTINUE ACROSS SOUTH CENTRAL LOUISIANA. BUT THIS ACTIVITY
IS EXPECTED TO END FOR A FEW HOURS WITH THE COLD FRONT EXPECTED
INTO THE COASTAL WATERS BY THIS AFTERNOON BEFORE STALLING. THERE
WILL BE A STRONG PUSH THAT WILL MOVE THIS FRONT BACK TO THE NORTH
BY EARLY THIS EVENING. THIS WILL SEE THE RETURN TO WARMER
TEMPERATURES BUT WILL ALSO SEE THE RETURN TO SHOWERS AND
THUNDERSTORMS. STORMS BECOMING NUMEROUS DURING THE OVERNIGHT
HOURS... AT THIS TIME THERE IS A THREAT THAT A FEW STORMS MAY
BECOME SEVERE WITH ISOLATED TORNADOES AND STRAIGHT LINE WINDS AND
HAIL POSSIBLE. THE THREAT FOR SEVERE WEATHER WILL END DURING THE
LATE MORNING HOURS FOR SOUTHEAST TEXAS AND TOWARDS SUNSET FOR
SOUTH CENTRAL LOUISIANA AS THE NEXT COLD FRONT EXITS THE REGION.
STRONG SOUTHERLY WINDS WILL PICKUP IN THE COASTAL WATERS TOMORROW
MORNING AHEAD OF THE FRONT AND SWING AROUND TO THE NORTHWEST AS
THE FRONT PASSES TO THE EAST. RAINFALL TOTALS WITH THIS EXIT
SYSTEM LOOKS TO BRING AROUND 1/2 INCH TO ONE INCH IN MOST
LOCATIONS AND UPWARDS TO TWO TO THREE INCHES IN ISOLATED
LOCATIONS.

BY WEDNESDAY MORNING TEMPERATURES TO FALL BACK INTO THE 30S WITH
FREEZING TEMPERATURES EXPECTED BY THURSDAY MORNING OVER A LARGE
PORTION OF SOUTHEAST TEXAS AND SOUTHERN LOUISIANA. STORMS RETURN
ON FRIDAY AS ANOTHER COLD FRONT WILL APPROACH FROM THE NORTHWEST.

MARINE INTEREST... A SMALL CRAFT ADVISORY AND A LOW WATER
ADVISORY WILL BE NEEDED FOR TUESDAY AS STRONG NORTHWEST WINDS WILL
MOVE ACROSS THE COASTAL WATERS. A GALE WARNING MAYBE BE POSTED FOR
THE OUTER WATERS.
