This might be a question(s) that can't really be explained and if you can't that's fine, but I'll ask them anyway. It's just something I'm curious about around here. Is there any reason as to why snowstorms move so swiftly (12 hrs or less) in the Southeast (specifically GA)? Why is it that other Southern cities all around us have MUCH higher single snowfall records than my hometown does? Is it a climatology thing? I don't wanna come off bias asking this because of where I live, it's just I've noticed, we can never seem to get above 4 inches of snow no matter how near perfect the setup is for us. Lately, I consider a 6 inch snowstorm a significant storm for us because we rarely get that high. Before January 9-10, 2011 you had to go back to January 2002 for the last time we saw a 6 inch snowstorm and if you go by the weather records kept at the airport alone, before 2011 you have to go all the way back to March 24, 1983 when we saw 7.9 inches!
Believe it or not, Atlanta has never has a 1 foot snowstorm recorded in weather records. The highest we've had is 11.7 inches going back to the 1940s, yet places like Columbus, Macon, Birmingham and heck even Savannah have accumulated that much or more from a single storm. The simple answer to all of this could turn out to just be terrible climatology, but I feel like it's has to be something else besides that.
Also, snowfall amounts can vary across a big metropolitan area like Atlanta. While Atlanta officially recorded 4 inches of snow during the March Blizzard of 1993, some suburbs had 10 inches of snow. The totals can vary from one place to another.
