Two waves within a very strong storm system will bring a threat for severe storms and some winter weather to the area.
- As the first wave moves through the area tonight, bands of heavy rain will produce up to 1.5 inches of rainfall over northeast Georgia with amounts of 0.5 to 1.0 inches elsewhere. The heaviest rain should end after midnight tonight. While creeks and rivers will rise to near bankfull, widespread flooding is not expected at this time. Strong to severe storms will also be possible late tonight from around 10 PM to 6 AM. Damaging winds and a brief tornado may be possible with the strongest storms.
- As the second wave moves in from the northwest on Monday, moisture and lift will combine with very cold temperatures to allow rain to mix with and change to snow over parts of north and west Georgia, roughly north of a Canton to Dawsonville to Helen line. With the cold temperatures aloft, any accumulating snow will be more likely at elevations above 2000 feet. Temperatures are expected to fall quickly into the upper 20s and lower 30s during this time, so any light snow accumulations could lead to hazardous road conditions. Snow accumulations should remain below 1 inch with locally higher amounts possible in higher elevations and on west and northwest-facing slopes.
- Finally, the cold temperatures and strong winds of 15-20 mph with gusts to near 30 mph will cause wind chill values to fall into the teens and 20s Monday night and Tuesday morning. Be sure to dress appropriately and avoid prolonged
