One thing about this area: It hardly ever snows (beyond maybe an inch or less) between Dec 26th and the first few days of January. Something always seems to happen (like boxing day 2010...lol) The only time I know of that we got something measurable in that time frame was the December I was born (1990). Snowed a day or two after Christmas.
Not to say it CAN'T happen...but just for whatever reason, it's historically rare...so I automatically assume it won't and see our December snow window as Dec 1st-25th, lol But man, if we ever earned a legit white Christmas...it's this year!
