WINTER WEATHER ADVISORY
Warning Issue Date: 1146 PM CST SUN JAN 03 2010
...WINTER WEATHER ADVISORY REMAINS IN EFFECT FROM 6 PM WEDNESDAY
TO 10 AM CST SUNDAY...
A WINTER WEATHER ADVISORY REMAINS IN EFFECT FROM 6 PM WEDNESDAY
TO 10 AM CST SUNDAY.
BY LATE WEDNESDAY NIGHT OR EARLY THURSDAY MORNING...A SURFACE LOW
WILL START TO DEVELOP OVER THE NORTHWESTERN GULF. THIS WILL CAUSE
TEMPERATURES TO WARM SLOWLY WITH MOISTURE INCREASING ACROSS THE
AREA. INITIALLY...LIGHT TO MODERATE SHOWERS WILL BE POSSIBLE BUT
BY LATE THURSDAY MORNING...A VERY COLD AIRMASS WILL BEGIN TO PUSH
INTO THE REGION. RAIN WILL BEGIN TO CHANGE OVER TO SLEET AND THEN
SNOW THURSDAY MORNING FOR AREAS IN SOUTHERN MISSISSIPPI ALONG
WITH THE FELICIANAS AND POINT COUPEE PARISH. BY THURSDAY
AFTERNOON AREAS ALONG AND NORTH OF THE 10/12 CORRIDOR WILL LIKELY
SEE A MIX OF RAIN...SLEET...AND SNOW. AT THIS TIME WE ARE NOT
EXPECTING MUCH IN THE WAY OF ACCUMULATION BUT A LIGHT DUSTING TO
HALF AN INCH OF ACCUMULATION ON GRASSY AREAS WOULD NOT BE OUT OF
THE QUESTION.
ALL OF THE MOISTURE WILL MOVE OUT OF THE AREA BY THURSDAY EVENING
AND THEN THE GREATER ISSUE ARRIVES...VERY COLD TEMPERATURES. AN
ARCTIC AIRMASS WILL CONTINUE TO MOVE IN AND REMAIN OVER THE AREA
FROM THURSDAY NIGHT THROUGH SUNDAY. THIS AIRMASS IS ASSOCIATED
WITH NEAR -40 DEGREE TEMPERATURES IN THE INTERIOR OF CANADA. WITH
A NICE SNOW PACK ACROSS THE UPPER AND CENTRAL PLAINS AS WELL AS
THE UPPER AND MID MISSISSIPPI VALLEY THE AIRMASS WILL NOT
MODERATE CONSIDERABLY. THE AIRMASS IS EXPECTED TO BRING VERY COLD
TEMPERATURES TO THE AREA THAT COULD BE COMPARABLE TO THE ARCTIC
OUTBREAK OF EARLY FEBRUARY 1996...BUT NOT AS LOW AS THOSE
EXPERIENCED DURING THE 1985 AND 1989 ARCTIC OUTBREAKS. MULTIPLE
NIGHTS WITH LOWS IN THE TEENS WILL BE POSSIBLE ACROSS SOUTHERN
MISSISSIPPI AND PORTIONS OF SOUTHEAST LOUISIANA THAT ARE
GENERALLY NORTH OF THE 10/12 CORRIDOR. ACROSS THE SOUTHSHORE...
LOWS COULD DROP TO INTO THE LOWER TO MID 20S FOR MULTIPLE NIGHTS.
THE COLDEST TEMPERATURES ARE CURRENTLY FORECAST TO OCCUR SATURDAY
MORNING WITH LOWS RANGING FROM 13 NEAR MCCOMB TO 23 AT GALLIANO.
EVEN THOUGH IT IS NOT FORECAST RIGHT NOW...THIS AIRMASS DOES HAVE
THE POTENTIAL TO CAUSE LOWS THAT COULD BOTTOM OUT IN THE SINGLE
DIGITS ACROSS ISOLATED LOCATIONS IN SOUTHERN MISSISSIPPI AND
MAYBE INTO THE TEENS AROUND THE NEW ORLEANS METRO.
IN ADDITION TO THE COLD TEMPERATURES BREEZY NORTH WINDS WILL BE
ONGOING BOTH FRIDAY AND SATURDAY MORNINGS. THIS IN COMBINATION
WITH THE REAL COLD TEMPERATURES WILL LEAD TO HAZARDOUS WIND CHILL
READINGS DOWN INTO THE SINGLE DIGITS.
THESE CONDITIONS COULD BECOME LIFE THREATENING AND AT THE VERY
LEAST HAZARDOUS TO PROPERTY. RESIDENTS SHOULD MAKE PREPARATIONS
FOR EXTREMELY COLD TEMPERATURES NOW.
TO PREVENT FREEZING AND POSSIBLE BURSTING OF OUTDOOR PIPES...
PIPES SHOULD BE WRAPPED...DRAINED...OR ALLOWED TO DRIP SLOWLY.
THOSE THAT HAVE IN-GROUND SPRINKLER SYSTEMS SHOULD DRAIN THEIR
SYSTEMS...OR COVER ANY ABOVE-GROUND PIPES TO PROTECT THEM FROM
FREEZING.
PETS ARE ALSO SUBJECT TO THE EXTREME COLD. KEEP PETS INDOORS AS
MUCH AS POSSIBLE. IF THIS IS NOT POSSIBLE...MAKE SURE OUTDOOR
PETS HAVE WARM DRY SHELTER...AND PROVIDE SUFFICIENT FOOD AND
FRESH UNFROZEN WATER.
BE PARTICULARLY CAREFUL WITH PORTABLE HEATERS...THERE IS A DANGER
OF FIRE OR POISONOUS FUMES. MAKE FREQUENT CHECKS ON THE ELDERLY.
MAKE SURE THEIR FURNACES ARE WORKING AND HEATING THE HOUSE
PROPERLY.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A WINTER WEATHER ADVISORY MEANS THAT PERIODS OF SNOW...SLEET...OR
FREEZING RAIN WILL CAUSE TRAVEL DIFFICULTIES. BE PREPARED FOR
SLIPPERY ROADS AND LIMITED VISIBILITIES...AND USE CAUTION WHILE
DRIVING.
