9:15 p.m.: The National Weather Service issued a flood warning Thursday night for Big Creek in Forsyth and north Fulton counties.
“Recent heavy rainfall has caused significant runoff into streams and rivers which will cause flooding in some areas,” the Weather Service said.
As of 8:30 p.m., Big Creek was at 6.4 feet and rising rapidly. Flood stage is 7 feet, and the river was predicted to reach nearly 7.2 feet Friday morning, then start falling in the afternoon.
The Weather Service predicted minor flooding of woodlands and fields along the creek between Cumming and Alpharetta and Roswell.
8:35 p.m.: This evening's weather marked a stormy transition to cooler temperatures through the holiday weekend, Channel 2 Action News meteorologist Brad Nitz said.
The National Weather Service lifted the tornado watch for all metro Atlanta counties around 8 p.m., and Nitz predicted “a gradual clearing overnight headed to a morning low in the low 50s, then partly cloudy by Friday afternoon, with the high in the low to mid 60s."
Metro Atlanta flirted with the record high temperature of 70 for Dec. 22 but fell 2 degrees short. The arriving front put an end to any record-breaking.
“The storms this afternoon came ahead of a cold front. Drier and cooler air will move in behind the front overnight,” Nitz said. The average high for this time of year is 53, “so we’ll still be 10 degrees above average Friday.”
Nitz predicted a mostly sunny and cooler Saturday, with a low in the low 40s and a high in the low 60s. Christmas Day Sunday is expected to be mostly cloudy with scattered showers and a high in the mid 50s.

6:30 p.m.: The tornado warning for parts of metro Atlanta has expired.
6:25 p.m.: The good news is, there's nothing for the moment coming behind the storms, Channel 2 Action News meteorologist Brad Nitz said. "Once the line (of storms) gets to the east of you, you are in the clear from damaging winds and perhaps tornado touchdowns."
While there's torrential rain across the region, the threat of tornadoes is diminishing.
“The word from the National Weather Service now is they are not planning to extend that tornado warning farther north and east,” Nitz said.
