When will it get cold

I live in Chattanooga, and it's in the lower-to mid 80s for highs, and mid and lower 60s for lows... Our average lows now are in the mid 50s and highs in the mid-to upper 70s!! When is the cold gonna get here, and when do you think we'll get a big snow or a first snow? Thanks,
