.A STORM SYSTEM…OVER THE NORTHWESTERN GULF OF MEXICO…WILL
INTENSIFY TONIGHT AS IT TRACKS EAST ACROSS THE NORTHERN GULF OF
MEXICO TO THE FLORIDA PANHANDLE BY DAYBREAK TUESDAY. IF IT WAS A
LOT COLDER…THIS WOULD BE A CLASSIC SCENARIO FOR A SIGNIFICANT
SNOW STORM OVER ALABAMA. HOWEVER…TEMPERATURES ARE RELATIVELY
WARM RIGHT OUT AHEAD OF THE SYSTEM…AND THIS LOWERS THE
PROBABILITY OF SIGNIFICANT SNOW AMOUNTS. WIDESPREAD
PRECIPITATION…MAINLY IN THE FORM OF RAIN…WILL SPREAD RAPIDLY
NORTHEASTWARD OVER ALABAMA TONIGHT. THE RAIN IS EXPECTED TO CHANGE
TO SNOW GENERALLY NORTH OF A LINE FROM MONTEVALLO TO
SYLACAUGA…TO ROANOKE…WHERE A WINTER STORM ADVISORY HAS BEEN
POSTED.

AT THIS TIME…SNOW AMOUNTS ARE EXPECTED TO RANGE FROM ABOUT ONE-
HALF OF AN INCH OVER JEFFERSON AND SHELBY COUNTIES…WITH ONE TO
TWO INCHES EAST TO THE GEORGIA STATE LINE. LOCALLY HIGHER AMOUNTS ARE
POSSIBLE OVER THE HIGHER ELEVATIONS OF NORTHEAST ALABAMA.

THE POTENTIAL DOES EXIST FOR AMOUNTS GREATER THAN TWO INCHES OF
SNOW… AND IF THIS MATERIALIZES EARLY TUESDAY…THIS ADVISORY
WOULD HAVE TO BE UPGRADED TO A WARNING.
