When I couldn't find any spot with more than 2.75 inches of snow either in the yard or in the street, I honestly thought something was wrong... because I'd already read the Alton/Gilford/Wolfeborough reports. However, the reality set in, as I swept the front porch and walkway in just seconds, and had cleared the driveway (with a small shovel) 5 minutes later.

R2B - you mention the hills to the *west* as being responsible for today's shadowing. Actually the flow was NNE all day - it ended up being the average wind direction for the day. I can't remember the last time we had a snowstorm with that much of a northerly wind.

Most of the accumulating snow here fell until 10 a.m. At that time, as the station's wind graph indicates, the direction shifted from ENE to NNE. Once that happened, *bam*, it was like someone turned a faucet off. The whole time, I could see the view to the south obscured by snow, and there wasn't much in the (SE-facing) WeatherCam all day but white... it just wasn't in the foreground of the picture. Directly NNE of here, we have the Ossipees. The shadowed area follows a line from the Ossipees to Black Cat to Meredith Bay, and the amounts increase with distance from the Ossipees.

Tonight when the wind shifted to more northerly I noticed the mountains apparently playing a role again. The steady snow had ended and most of the lake was precip-free. In one of the frames of the radar loop, I saw a blob of snow literally form out of clear air, just north of Red Hill's location, and 2 frames later the same thing happened just north of the Belknap Range - on the southern shore of the lake. Neither blob moved.... they lasted for a few more frames right where they were, and then dissipated.
