…WINTER PRECIPITATION POSSIBLE MONDAY NIGHT INTO TUESDAY…

A STRENGTHENING LOW PRESSURE SYSTEM WILL CROSS THE NORTHERN GULF
OF MEXICO MONDAY AND MOVE INTO NORTHERN FLORIDA BY TUESDAY AFTERNOON.
AHEAD OF THIS SYSTEM…MOISTURE WILL SPREAD INTO CENTRAL ALABAMA
MONDAY AFTERNOON RESULTING IN WIDESPREAD RAINFALL. COLDER AIR WILL
FILTER INTO THE AREA MONDAY NIGHT FROM THE NORTHWEST…RESULTING
IN THE POSSIBILITY OF WINTER WEATHER.

AT THIS TIME…RAIN IS EXPECTED TO MIX WITH OR TRANSITION TO SNOW
STARTING EARLY TUESDAY MORNING…AND THEN CONTINUE THROUGH THE
DAY ON TUESDAY…EVENTUALLY ENDING FROM WEST TO EAST TUESDAY
AFTERNOON. THE BEST CHANCE FOR SNOW IS ALONG AND NORTH OF A LINE FROM
EUTAW…TO CLANTON…TO ROANOKE.

THE CURRENT FORECAST IS FOR ONE INCH OR LESS OF SNOW IN THESE AREAS.
HOWEVER…THIS FORECAST IS BASED ON TEMPERATURES STAYING JUST WARM
ENOUGH SO THAT MOST OF THE SNOW THAT DOES FALL WILL QUICKLY MELT.
HOWEVER…IT WOULD TAKE A TEMPERATURE DROP OF JUST 2 OR 3 DEGREES TO
CAUSE THESE AMOUNTS TO INCREASE SIGNIFICANTLY.

EVEN AT THIS RELATIVELY LATE JUNCTURE…THERE IS STILL CONSIDERABLE
UNCERTAINTY IN THE FORECAST. MINOR CHANGES IN THE STORM TRACK AND
INTENSITY COULD HAVE A CORRESPONDING MAJOR IMPACT ON THE POSSIBILITY
OF WINTER PRECIPITATION. THE RAIN/SNOW TRANSITION LINE AND
ACCUMULATION POTENTIAL WILL LIKELY NEED TO BE REFINED WITH FUTURE
FORECASTS. CENTRAL ALABAMA SHOULD STAY TUNED FOR UPDATES ON THIS
DEVELOPING WINTER WEATHER SITUATION.
