A Winter Storm Watch has dialed back a bit on possible accumulations from a wintry mix expected to hit Tuesday.
An update late Monday morning expects accumulations of a half-inch to 2 inches along and south of a line from Haralson to North Fulton to Madison County.
The National Weather Service also has posted a graphic on the Peachtree City locations website indicating up to 4 inches of snow and sleet possible across southern sections of Middle Georgia.
A cold front sweeping through has colder air building behind it.
If the forecast holds, moisture flowing in from the Gulf of Mexico will be whisked in as temperatures fall, potentially dumping snow on the Macon area.
Late Sunday, it looked like the swath of the state most affected could stretch from Columbus to Macon with the most accumulation south of Atlanta and Interstate 20.
North Georgia, which typically sees more snowfall when winter storms roll through, may only see flurries.
This ones a whole different animal, said meteorologist Adam Baker of the weather services Peachtree City office.
The earlier forecast indicated south of Forsyth down to around Perry might catch the brunt of the storm -- if it materializes -- with snow accumulations 3 inches or greater.
The projected snowfall and ice amounts are likely to shift somewhat because its still a couple of days out, Baker said Sunday night. But our best shot at what were seeing with the latest forecast here is that in the Macon area you could see up to three inches of snow.
The heaviest snow was expected overnight Tuesday.
But you could start to see an onset of some sleet mixed in with it starting later in the day Tuesday, Baker said.ing
The 3-inch mark, he said, was like any forecast, a best guess.
That said, Baker added, This could be under-doing the amounts, too. Weve got so much moisture, so were trying to communicate some uncertainty with the range of amounts here.
The weather service forecast called for high temperatures in the low 60s here Monday.
Then the chill hits.
Tuesdays high looks to be in the low 40s, with overnight lows in the upper 20s.
