Re: Climate zones by heating and cooling

Message from Tommy Nashville-Miami

Maybe because of how quickly the spring heats up and stays hot to the west. The Hardiness Zones are only taking those extreme lows into account. I think this map shows why there's a difference between northern 7's and southern 7's. Also, I notice the MS River bulge northward on this one which I've always wondered about.
