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
History was made by Hurricane Iselle this week and I have some of the most impressive images and maps from the storm.
We're monitoring a total of six storms in the Atlantic and Pacific, and some of them are record-breakers.
As is often true this time of year, the tropics are busy, with five notable named storms. Among them are three storms near Hawaii, and Bertha is back for the seventh time.
There's been a lot of news on amateur drones since I tested the DJI Phantom Quadcopter for storm chasing purposes last fall. Not to drone on, but let's take it from the top.
Today I'm pleased to announce a new suite of world radar maps and advisories from the national weather services of several countries on AccuWeather.com.
There's much ado this week about the polar vortex visiting the U.S. this week, but it wasn't long ago that we set over 7,800 cold records in July.
