So, what are the chances of snow by Christmas? Here in southwestern Connecticut, weather records have been kept for a long time. Our climatology is based on record-keeping over a 40-year period.
Based on history, shoreline communities such as Stamford, Darien, Stratford, and Milford have a 30% chance of seeing at least one inch of snow on the ground by December 25. There's a 10% chance of at least five inches of snow on the ground by then. However, we have a zero percent probability of having ten inches of snow or more on our front lawns by Christmas morning.
Inland, the odds are more favorable. People living north of the Merritt or Wilbur Cross parkways have a 57% chance of at least one inch of snow for Christmas. The odds are slightly lower than one-in-four (23%) for five inches of snow, and quite slim (3%) for at least ten inches of snow. However, residents in Wilton, Redding, Easton, and Woodbridge have a much better opportunity of seeing snow on the ground than their shoreline counterparts.
As far as the rest of New England is concerned, the chance of a white Christmas gets even better. Northern Connecticut and southern Massachusetts have about a 40 to 60% chance of at least one inch of snow; central New England's chances improve to 60 to 80 percent; and northern New England (80 to 100%) is virtually assured of having a White Christmas.
One of the more memorable snowstorms which occurred in late December was the Christmas Eve storm of 1966. We received over a half-foot of snow (6.9"), making roads quite slippery and travel very difficult. I distinctly remember my family on our way to visit my grandmother in the snow, but my parents deciding the drive wasn't worth the risk. We turned around and headed for home, but the car slid several times on the snowy roadways.
You may recall the snowstorm which delivered more than nine inches of snow to southwestern Connecticut the weekend of December 19 and 20, 2009. The snow began late Saturday evening, and six inches had accumulated by midnight. The snow tapered off early Sunday morning, but not before another 3.2 inches caused headaches for holiday shoppers the last weekend before Christmas.
Another recent snow occurred on Christmas Day, 2002. Some light snow happened early that morning, but a steadier and heavier snow developed by later in the afternoon and evening. The snow totals were quite impressive locally. Darien received 10 inches of snow by the time the storm exited the following day. Redding (9.5"), New Canaan (9.2"), Norwalk (7.0"), Greenwich (7.0"), and Westport (6.5") each saw at least a half-foot of snow!
On the flip side, I'm sure you recall December of 2006. The afternoon high temperatures from December 23 to 26 reached 58, 52, 44, and 50 degrees respectively, well above the 38-degree normal high. Over an inch of rain fell December 23 (1.15") and over a quarter-inch (0.28") was recorded on Christmas Day. We were left dreaming of snow for quite some time.
