I was just going to say that. After this initial band, the rest of the precip moving in is light with breaks in it. We'll probably get a good portion of our accumulation from this band. After this, it'll be periods of light snow the rest of the way.

Just pull up the Weenie, err I mean the Intellicast Radar, it will make you feel better. :lol:

Snow has lightened up here but it looks like another heavy batch of green about to move in.

It looks to be moving quickly so I think the heavy bursts will last half hour or so and then lighten up over the next 4 or 5 hours.

2 1/2 here in Gibsonia, roads are awful i seen only 2 roads somewhat cleared, also had a clap of thunder an hour ago, impressive

6-10 inch totals are a good bet

You can't count the snow already on the ground.....

You gonna ever tell me your crossroad with Rt 8 so I can see how impressive your snowfall is?
