And? I’ve been here. 8-10 years is about right for a frozen precipitation event that substantially affects traffic across the metro area, your mechanistic recitation of meteorological data notwithstanding. Wisdom > Data

Unbelievable.

Two short years ago...

January 11, 2011
Wednesday, Jan. 12, 2011 marks the third day of snow and ice in the Atlanta metro area. Many businesses and schools remained closed, mail has been delayed, flights canceled and area public transit such as MARTA, Gwinnett County Transit and Cobb Community Transit are operating on limited service...The Georgia Department of Transportation is still urging commuters to stay home, reporting roads will likely refreeze again overnight Tuesday.

OK, so I wasn’t verbose enough. An event creating a traffic disaster such as we saw this week happens every 8-10 years. In 2011, the timing was such we didn’t have that. It snowed. We stayed home. It was fine.

Beyond that, please see SampleMan’s post #48 in this thread.
