HISTORIC GEORGIA SNOW STORM – 12/8/2017

posted in: NEWS, WEATHER | 0

Many last minute milk sandwiches were made over this weekend in many North Georgia communities.

 

What was originally forecast to be a trivial snow storm became an event that rivaled the March 13, 1993 Atlanta blizzard. Many areas along a line from Carrolton, Georgia to Canton, Georgia saw snow totals of 12″+. This was an over achieving storm, which became apparent as snow total forecasts were being blown away in areas of Austin, Texas and San Antonio, Texas the night before. The GFS (Global Forecast System) and European models were both showing light snow accumulation (1″-2″) around the Atlanta metro area and Northern suburbs Friday into Saturday (12/8/2017 – 12/9/2017). The NAM (North American Model) was the outcast of the three, with a bullish 11+” forecast. It seems as though the NAM prevailed in this event, and verified with a high degree of accuracy. This storm was a historic anomaly. Many would say this was the perfect Georgia snow storm with minimal icing. Even still, many people were without power for at least a few hours, and traffic escaping downtown was comparable to a rush hour, Falcons game weekend. In many ways, however, this storm could have been a lot more tragic had temperatures dipped below freezing upon onset. Perhaps the saving grace of this event was the fact that temperatures hovered around 33 degrees Fahrenheit for most of the duration.

The storm was fueled by two waves of moisture. The first wave began in the early morning hours of December 8th in extreme Northwest Georgia, and transitioned into the Atlanta metro area by lunch time. Road conditions began deteriorating in the Northwest Suburbs of Georgia around 11:30pm as moisture content increased. This led to 1″+/hr snow fall rates in certain areas. It was about this time that school systems and work places realized the storm would continue to over perform. Once again fears of another Snowmageddan 2014 grid lock were being realized, however road surface temperatures kept that mostly under control.

In Northwest Georgia, the snow continued falling at a steady rate until the over night hours. By about 9:00pm, roughly 9″ of snow had fallen in the Kennesaw area. There was a lull in snowfall for roughly three hours before the second moisture wave emerged from Alabama. The second wave gave way to an additional 3″ of snow by 10:00am Saturday morning. The landscape was unrecognizable and looked more like a scene from “The Lion, the Witch and the Wardrobe” than a bustling suburbia. In most cases the snow resulted in some incredible scenery, and many great memories. In a lot of ways, up to this point, this event is the Great Southern Blizzard of the current generation.
