This situation is quite similar to the big, unexpected Nov. 2-3 1966 snowstorm that moved from the Fla. panhandle due north up the west side of the apps. Temps. were very marginal and Louisville got 13" and the temp. stayed around 33°-34° the whole time. Temp profiles were probably a little different/colder, but interesting similarities at this point. I remember the forecast the day before called for rain, possibly ending as flurries...
