Around here 2 inches will shut down every business and school in the state and cause huge pileups regularly at intersections and on highways. It's not always about the amount of snow but about how prepared the community is to handle it. Plus when warmer climates do get winter weather it can be worse on the roads than colder locations because the snow will often partially melt then refreeze as a smooth slab of ice.

I think that's actually what this meme is intending. All of these are indicative of the US south.
