UPDATE Dec. 2013: Climate.Gov has released a newer and more accurate version of their "Chance of a White Christmas" map, based on the new 1981-2010 data set. Unfortunately, due to it being a different design, I can't compare it to the previous climate data set any more than I did last year in my blog entry "White Christmas vs. Global Warming."
ORIGINAL REPORT (Nov. 2009):
With holidays coming up, the song "Over The River" starts playing in my head... but why did the "horse" have to "know the way through... drifting snow" in a Boston suburb for Thanksgiving? It turns out that most Holiday lore was invented in the 1800s during a climatic event known as "The Little Ice Age," when pre-holiday snow was common in the populated areas of New England and Europe. I've dusted off a blog entry that I wrote in 2006 and have refreshed it with larger graphics and corrected links.
Read on to find out to find out the meteorological significance of these holiday gems:
"Over the River and Through the Woods" (1840s)
- November snow was common in Boston
Charles Dickens' "A Christmas Carol" (1840s)
- London would often have snow cover in December
"Twas the Night Before Christmas" (1820s)
- December snow was typical then in New York City
- Reindeer (Arctic animals) aren't found at this latitude anymore
The Song "A White Christmas" (1942)
- Was done later but they were "dreaming" about stories their grandparents told them
The Thanksgiving snowstorm has begun this Wednesday morning.
Do me a favor, travel Tuesday, or tell your family to hold on to the turkey until Friday.
Last year this time, a major winter storm in the Northeast was rumored for the biggest travelling day of the year... and so it is again this year:
Extreme lake-effect snow fell south and east of Buffalo, New York, this week, but is it a record? Not even close... so far.
The second shot of reinforcing cold air from last week's polar vortex invasion is coming in -- as more than half the nation is snow-covered.
Yes, that term "polar vortex" is back in the news. Please take this arctic outbreak for the serious meteorological beast that it is; see stats and maps here.
