Back to Back Storms

A storm will come in along a stalled front Tomorrow, giving us a day of light and fluffy snow. Then, a much more powerful storm will come in right behind it giving us a walloping of snow. The second storm is warmer, and the trick is determining the mix line. At this point, it seems it will make it to the Boston area briefly, cutting back a tad on snow amounts. However, a degree or 2 could make a difference between sleet and ending up with 20 inches of snow. I will have better confidence tomorrow.
