What's the farthest south the Polar Vortex has ever made it? Let me add this story into the mix: http://theweathercentre.blogspot.com/20 ... ortex.html
Where was the polar vortex during the Great Blizzard of 1899?
How close would the polar vortex need to get for cfla to be bitterly cold (highs lower 40s lows lower 20s)? Do we even need the polar vortex in the US to get bitterly cold in cfla, or can it get bitterly cold without it coming into the US?

I'll try to answer your question to best I can. I'm far from an expert in the stratospheric polar vortex. Where was it the PV in 1899? We have no idea. The polar vortex exists well above where even commercial aircraft fly. It exists in the stratosphere (the 2nd layer of the atmosphere). There wasn't upper air observations occurring back in 1899.
These past two winters, what has been referred to as the polar vortex has been a strong tropospheric trough situated over Hudson Bay in Canada. This semi-permanent weather pattern has allowed multiple pushes of polar air to plunge into the eastern half of the US.
As for Florida, I guess I don't have a good answer. I'm not sure what the patterns were that have caused previous arctic intrusions into Florida.
