Biggest snowstorm since 2007 on the way?

Wow, I go to bed thinking everything is on schedule with timing, and snow amount, and I wake up thinking I slept thru two or three storms.

Our largest storm of the 2008-09 winter was 16.5 inches, back in December. We have a shot at breaking that today and tonight. Computer models have trended slightly further north with the warmer air, which means the storm will move further north, and bring its swath of heavy precipitation right over the Lebanon area. Evidence of this further north track are already being observed-

A coastal front has formed along the MA/NH border in Essex county. On one side, its about 30 degrees, and on the cold side its around 19-20. Within 20-40 miles north of the coastal front, there is usually very heavy snow, and there is a chance we will get into that band later this afternoon. I think the sleet line will make it up into southern NH, possibly as far north as Manchester and Concord. So just to the north and west, snow will accumulate up to 3 inches per hour and it will last till after midnight.

What could go wrong? There is a dry slot already forming in Pennsylvania heading towards New England. That SHOULD fill in when the storm moves off the coast and wraps in some more cold air. But we'll see.

Accumulation? At least a foot, and if we get into some of the heavier bands, I'd say 18-20 inches, with higher amounts likely. The average heaviest snowfall will be in Maine with 20-25 inches+ there. This is quite a development and a huge surprise to me. Normally I'd stick with my 10 inch amount, but the computer models have left me no choice but to raise them substantially. Hope I don't get burned for it...

Roads will go down hill rapidly today, and honestly, if yo live more than a mile from work, its not worth going in today. When it snows at more than an inch per hour, traveling is not recommended. Also, when it is snowing at more than 1 inch per hour, road crews have an impossible task of clearing the roads because they cannot keep up with the heavy accumulation.

I'll try to have more updates as the day goes on.
