The first widespread frost of the season could set in Friday night and Saturday morning.
The National Weather Service predicts temperatures in the upper 20’s and lower 30’s for the northern half of the state, and a chance of snow Friday in north Georgia.
Assistant State Climatologist Pam Knox says while it may seem sudden, this first frost is right on time.
"We’re really just about on average. But I think it’s taken people by surprise just because it has been so warm this year."
Knox says a La Nina weather pattern has brought a warm jet stream from South America, and it will continue.
"And so we should for the most part of the state – especially in the south – we should see warmer and drier temperatures than usual this winter.”
She says that will likely mean a dry spring because the soil will not be recharged with water.
For this weekend, Knox says 32-degree temperatures will kill most outdoor plantings – except cold-weather plants like pansies.
Sensitive vegetation and young trees should be covered.
