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
Eastern Pennsylvania was darkened by a massive, triple-decker shelf cloud last night. It was the first thunderstorm of the year, and it did not disappoint.
This year had been a markedly (and thankfully) slow year for tornadoes. That luck ran out last night, when multiple twisters struck Oklahoma and Arkansas.
After a few warm days, the ice was on the move, in some cases causing damage. Here are photos and videos from the Pennsylvania Storm Chasers.
Super Cyclone Pam, at Category 5 Hurricane strength, is razing the island nation of Vanuatu today. How does it compare to historical storms there?
The media is afire with claims of a new 24-hour snowfall record, but what about the one I reported on last month, and others in the past?
Today, I can bring you the good news that the AccuWeather Channel has launched nationally on a digital television network.
