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
Today, I remember the earliest fall snowfall in central Pennsylvania history, which occurred 5 years ago, mid-month.
I don't believe this has ever happened in Hurricane history: Major Hurricane Gonzalo is striking Bermuda tonight, just as soon-to-be-hurricane Ana approaches the Hawaiian islands.
Recapping some of the things I've seen on weather radar over the years... birds, bats, butterflies, locusts, and mayflies.
Just after sunrise in the west Pacific Ocean last night, we were able to look down into the eye of Super Typhoon Vongfong.
An amazing display of asperatus clouds showed up in New York City this morning, but what causes them?
Vortexes of air constantly surround us; for the first time in my life, I've videotaped dust devils near AccuWeather HQ during unusually dry and calm weather.
