October was much less snowy than it should have been in the Continental United States. Here's a map I made of normal October snowfall (colors) vs. October 2010 snowfall, as reported by the official climate stations in AccuWeather's database. As you can see, the coverage of non-zero reports is much smaller than it should have been.
Denver had no snow, something that hasn't happened in 88.5% of previous years of record. Flakes haven't been seen at all in most of the country. I'm not sure how much snow Montreal, Quebec, Canada normally has by now but I bet it's a lot more than the 1.2" they got at the end of October.
We've seen November twisters before, but the tornadoes last week were huge, fast-moving, late in the day and unusually far west.
El Nino is likely responsible for recent record flooding in Death Valley, California, and heavy snow yesterday in Reno, Nevada.
Forty years ago, a ship known as "The Edmund Fitzgerald" sank on Lake Superior during a massive storm.
Astoundingly, Socatra Island is being hit with their second Category 3 hurricane in less than a week.
The forecast was for the Northern Lights to appear in mid-latitudes this week, but it didn't happen. Space weather forecasting is tough!
After razing the island of Socotra, the strongest cyclone to hit Yemen still looms offshore.
