Pretty
Ring GalaxyCurrently attempting to investigate severe weather in the continental US, in terms of times of year it tends to happen, and where, so I have a general idea of when I do not want to be in specific parts of the US during my year of wandering. I pretty much already know the Northeast's weather (I'm intending to try to avoid wanderings involving snow, for example). Everywhere else, not so much.
Wikipedia makes me happy, as it appears to be the most useful source of this kind of information thus far.
