Important Updates
➔ The risk for accumulating snow and freezing rain bringing impacts to the area persists.
➔ Time period of greatest impacts remains Tuesday afternoon through Wednesday morning.
➔ An extended period of bitterly cold temperatures will occur.
➔ There is a low-end risk for some freezing rain Wednesday night into Thursday morning and again Thursday night into Friday morning.
Winter Storm Severity Index (WSSI)
➔ There is a 50-70% chance for winter precipitation to produce minor impacts over the area.
◆ Minor impacts = accumulations of snow/ice are enough to produce travel issues.
➔ There is also a 30-50% chance for winter precipitation to produce moderate impacts over the area.
◆ Moderate impacts = accumulations of snow/ice are enough to pose a risk to life and property.
➔ These probabilities are still reasonably high this far out in time.
Key Messages
➔ Cold Temperatures: High confidence remains that bitterly cold temperatures will impact southeast Georgia next week.
◆ Low temperatures may reach near record levels Wednesday night.
◆ Dangerous wind chills are possible Tuesday night into Wednesday night.
➔ Winter Precipitation Potential: An area of low pressure will pass to the south and offshore by the middle of this week and could bring winter precipitation to the area.
◆ The track of the surface low will be key to precipitation types and amounts.
◆ The probabilities for accumulating snow and freezing rain impacting the area continue to increase
● 1 to 2 inches of snow possible (most areas) with 0.05-0.20” ice (mainly southern coastal counties).
● Still unclear whether freezing rain, sleet or snow will prevail in the coastal counties. The risk for all snow is highest away from the coast.
◆ The window of greatest impacts looks to be Tuesday afternoon into Wednesday morning.
◆ There is a low end risk that freezing rain will occur Thursday and again Friday, mainly in the mornings.
➔ Travel: Some travel issues could continue into Wednesday night and Thursday as wet roads could refreeze.
