...Potentially Hazardous Winter Weather Scenario Late Thursday
Night Through Saturday Morning...
We are following the development of potential early season winter
weather for portions of North and Central Georgia beginning late
Thursday night with impacts lasting into Saturday morning.
For the remainder of tonight, expect light rain or just cloudy
skies. The rain shield will expand northward through Thursday
afternoon with 80 percent rain chances across Central Georgia
decreasing to 30 to 40 percent over the Atlanta metro. While this
is occurring, colder temperatures will begin moving in from the
north with mid to upper 30s for most areas late Thursday evening.
Somewhere in the zone where the precipitation meets the coldest
air, the possibility exists to see a transition to a mix of light
rain and snow and then possibly to all snow Late Thursday night
into Friday AM.
Our anticipation at this time is that this zone will only be on
the order of 20 to 40 miles wide and the exact location of where
this zone sets up has a high amount of uncertainty. We are
therefore asking all residents to be prepared for the possibility
of a wintry mix late Thursday night into Friday and stay tuned to
forecast updates through Thursday from this office and local
media outlets. The narrow zone that experiences wintry weather
could see from one half to one inch of snow accumulations by late
In addition, much colder temperatures will plunge into the area
Friday night into Saturday morning. Although most all of the
precipitation will be gone by then, residual wet roadways will
freeze very quickly prior to any drying that takes place. This
black ice scenario would create hazardous travel conditions
areawide Friday night into Saturday morning, especially for
elevated surfaces such as bridges and overpasses.
