CURRENTLY THE LATEST COLD FRONT IS MOVING THROUGH THE COASTAL
WATERS OFFSHORE OF ST MARY PARISH IN SOUTH CENTRAL LOUISIANA.
A LARGE AREA OF MOSTLY LIGHT RAIN COVERS THE GULF AND THE BETTER
PART OF SOUTHERN LOUISIANA WITH A FEW SPRINKLES NOTED IN
SOUTHEAST TEXAS. TEMPERATURES ARE RANGING FROM THE MID 40S AROUND
AEX TO THE LOWER 50S FOR BPT AND LCH WITH NEAR 60 FOR LFT. THIS
WILL PRETTY MUCH BE THE HIGH TEMPERATURES FOR TODAY AS COLDER AIR
WILL CONTINUE TO ADVECT INTO THE REGION.
RAINFALL TOTALS WILL BE RANGE FROM 0.10 IN THE LAKES REGION TO
ALMOST AN INCH DOWN ALONG THE SOUTH CENTRAL LOUISIANA COAST TODAY.
THE GROUND IS VERY SATURATED AND THESE ADDITIONAL RAINS WILL SPILL
INTO THE LOW LYING AREAS AND BAYOUS. CURRENTLY THE SABINE RIVER AT
DEWEYVILLE IS EXPECTED TO RISE ABOVE FLOOD STAGE FRIDAY EVENING
WITH MINOR FLOODING EXPECTED. GLENMORA IS A FLOOD STAGE THIS
MORNING WITH MINOR FLOODING AND THE GAGE AT MORGAN CITY IS REPORTING
MINOR FLOODING ALSO. RAINS THOUGH ARE NOT EXPECTED TO RAISE THE
RIVER LEVELS MUCH AS RAINFALL TOTALS WILL REMAIN ON THE LOWER
SIDE.
A STRONGER CANADIAN COLD AIRMASS THAT HAS BEEN DROPPING THROUGH
THE UPPER PLAIN STATES IS EXPECTED TO MOVE QUICKLY TOWARDS THE
REGION AND WILL EXIT INTO THE COASTAL WATERS THIS EVENING. THIS
LATEST FRONT WILL AGAIN DRY THE REGION OUT WITH MORNING LOWS
BELOW FREEZING AROUND AEX AND FROST ACROSS THE LAKES REGION IN
SOUTHEAST TEXAS AND CENTRAL LOUISIANA. IT WILL REMAIN COLD THROUGH
THE DAY ON FRIDAY ALTHOUGH SKIES ARE EXPECTED TO CLEAR. SATURDAY
MORNING LOOKS TO BE THE COLDEST DAY WITH SOME UPPER 20S AROUND
AEX AGAIN WITH FREEZING TEMPERATURES FOR THE LAKES REGION AND ONCE
AGAIN INTO CENTRAL LOUISIANA. FROST WILL BE POSSIBLE AS FAR SOUTH
AS THE I-10 CORRIDOR. BUT SATURDAY AFTERNOON WILL START A WARMUP
OF SORTS AHEAD OF MORE SHOWERS ON SUNDAY AFTERNOON. WE WILL GO
THROUGH ALL OF THIS AGAIN FOR THE FIRST PORTION OF NEXT WEEK.
