Winter Storm Watch

A disruptive winter storm will bring a wintry mix to parts of our area this weekend.  The National Weather Service will be tracking an area of low pressure that will strengthen as it moves out of the northern plains into the southeast Saturday.

A Winter Storm Watch has been issued for Northeast Georgia. In some areas, 2 to 5 inches of snow and up to a quarter of an inch of ice will be possible. Expect difficult and dangerous travel and the possibility of power outages. The final snow and ice forecast is not yet known as the forecast ever evolves.

 

There is still some uncertainty in the type of precipitation and the amounts of any snow, sleet or freezing rain there may be since the system is still a couple of days away.

The radar data is showing an area of low pressure moving through the southeast on Sunday. 

The National Weather Service said that it has been 1,454 days since the last time their Atlanta site has seen measurable snowfall. That is the second longest streak on record, they said. Our last measurable snow occurred on January 18, 2018, nearly four years ago. 

Impact Potential

The greatest impact potential will be northeast of the inner Atlanta metro, where significant travel disruptions are likely.

For areas in Northeast Georgia, including the North Georgia mountains, Lake Lanier, and around the I-85 corridor, high impacts are possible. Significant accumulations of snow and/or ice are possible.  The National Weather Service still do not know the final snow and ice amounts. Major travel disruptions are likely, including difficult and dangerous roads, even if treated. Power outages will also be possible based on the amounts of ice and wet snow coupled with gusty winds as the storm pulls away. There is a high confidence that this part of the state will have impacts from the storm and you should plan on staying off roads during the day Sunday and at least through early Monday morning.

 

For the inner Atlanta metro area, the I-20 corridor and northwest Georgia along I-75, plan on moderate impacts. Impacts are possible, but there's still some uncertainty in the snow and ice potential. The wintry mix could cause travel disruptions. This forecast is ever-evolving as the final track and strength of the cold is better known. 

 

For areas well south of I-20, mostly rain is expect. Although you could see a little snow and/or ice, travel is not expected to be impacted. 

 

Time Line:

 

Low pressure will approach our area Saturday, bring in rain by the end of the day. The rain will be with us during the evening into early Sunday night. Later overnight, the changeover to a wintry mix takes shape. This wintry mix will be ongoing Sunday, ending with snow.

This is model data of the timing. The timing and types of precipitation will change. 

Saturday morning looks dry. In the afternoon a few showers begin to work into North Georgia. These may start with some wintry weather already in the highest elevations.
