Areas affected...Far West-central MS...Central AL...Northwest GA

Concerning...Heavy snow

Valid 081355Z - 081700Z

SUMMARY...Occasionally moderate to heavy snowfall (i.e. snowfall
rates around 1 inch per hour) are possible over the next several
hours across portions of central AL and northwest GA

DISCUSSION...Recent surface observations show that temperatures
across central AL and northwest GA have cooled enough to support
snow. Several sites are already reporting moderate snow with
isolated/brief instances of heavy snow (i.e. visibility less than
1/4SM) also being reported. Relatively heavier band of precipitation
is currently ongoing across southeast MS/southwest AL and its
northeasterly motion is expected to take it into central AL and
northwest GA over the next few hours. As a result, snowfall rates
may occasionally top 1 inch per hour in isolated locations.
Subfreezing surface wet-bulb temperatures are expected to remain
north of a line from MEI northeastward to RMG, keeping areas south
of this line predominately rain.
