Winter revisited?

A Winter Storm Watch is still in effect for tonight through Wednesday night for an expected 4 to 8 inches of snow. The precipitation is expected to start as rain this evening and change to snow overnight. This is the kind of forecast I really hate, because there is a huge bust potential. If the dry air currently in place hangs around longer than expected, accumulations will be much lower. There is also the possibility that the warmer air could last longer as well, leading to more rain. Overall, I would not be surprised if snow totals end up being much lower than forecast. However, the models are in better agreement today, so hopefully that means something.
