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.
