Special Weather Statement

… Fast moving system to bring potential winter weather to area
Thursday evening…

an upper level disturbance is expected to move across the
Mississippi and Alabama Thursday morning and gradually spread
moisture northward across the local forecast area Thursday
afternoon into Thursday evening. This will lead to light rain
developing from Columbus to Macon initially by 10 am to noon. From
there… it will spread northward to start in the Atlanta Metro
during the early afternoon hours. At the onset of
precipitation… the temperatures will be in the lower 40s which
will result in just a cold rain. However… as the rain
continues… the temperatures will fall with light snow mixing in
with the rain along and north of a La Grange to Athens line and up
to the Atlanta Metro during the evening hours Thursday. North of
the Metro and including the mountains… the precipitation will be
mainly snow but amounts are expected to be very light. All the
precipitation will end by late Thursday night with colder
temperatures moving in its wake.

at this point… this looks to be a far different scenario than
last week with temperatures remaining above freezing while the
precipitation is falling. Also… lighter amounts of precipitation
will further limit any accumulation potential. Based on these
factors… we are going with little to no accumulation for most all
areas with the exception of the higher elevations of the mountains
where a dusting is possible. By far… the biggest potential impact
will be the black ice Thursday night as sub freezing temperatures
rush in and residual wet roadways become slick due to ice. This
threat could persist into Friday morning with temperatures not
expected to rise above freezing until 10 am.

Summary… this is a rapidly evolving winter weather event with the
scope remaining uncertain. We will be vigorously inspecting the
latest data to come in this evening to determine snow amounts if
any across the area as well as potential impacts for Thursday
night and Friday travel.
