Global weather patterns are always changing and lately there are some remarkable anomalies. This could be a growing trend towards more violent
weather. The best source is NOAA in my opinion, but you have to know where to look. They didn't design the site with the amateur weather enthusisast
in mind. Here's a collection of links that I think are helpful when trying to qualify "strange" weather.
