Like anywhere else in the southeast or midwest the threat of a Tornado occurs when cold air meets warm air, usually in the months of April/May and October /November. I've lived in Huntsville for 19 years, I don't know of anyone personally who's house has been blown away.
Huntsville:
*Country's best value for
salaries & cost of living (#1 in the USA): Salary.com
*Top 10 city in the USA for overall standard of living: Expansion MGt Mag
*Top 15 city in the USA for Business : Forbes
*Top 20 Midmarket, 7.2% 5 Year Job Growth: Inc Magazine
* 1 in 10 people have a PHD, *Most affluent Metro in the state * Fastest growing metro in the State, etc. etc. etc. blah blah the list goes on.
It's a freaking great place, its the best city in the State and its definetely one of the best in the whole region in my opinion. See how much your money can buy here, it'll blow your mind. Peace! more national recognitions is below:
