I just left downtown Nashville and came back to my office. The temperature gauge in my car said 70F. I couldn't believe it, so I checked weather.com at the next stop light. Yep, 70. Tomorrow at 7AM it is supposed to be 32F and begin snowing. The snow will continue until 8PM, when it will be down to 27... and continue dropping through out Friday night until it hits 20. That's a 50 degree fahrenheit drop in a really short time (in case you're not good at math). It's like Armageddon at the grocery stores right now. For one day of snow.
