There's a saying in New England, "if you don't like the weather, wait five minutes and it will change".
You might need a coat in the morning but by afternoon you're looking for some place with air conditioning. We've had snow in April and 70F degrees in December. Just in the time I've lived in Connecticut, we've experienced an earthquake, hurricane, floods, blizzards and just recently a tornado. I think we're safe from volcanoes but I can't be 100% sure.
This challenge is open to so many possibilities. The only way I can get a handle on it is to pick one type of weather, my favorite type, and just focus on that. But if I wait 5 minutes that might change.
