I currently do not have an anemometer but would like to get one, any idea on where to find one (reasonable but decent? possible?).
You're going to get some wind out of this. Wind is expected to be from the north.

The winter storm warning has been upgraded to a blizzard warning for Belknap & Carroll Counties a few minutes ago. That means wind sustained at 35 mph for at least 3 hours, combined with falling or drifting snow, to create visibility of less than a quarter-mile.

The blizzard warning is being expanded west to inland areas as well as coastal, as forecasters at the NWS become confident in a prediction that the above criteria will be met there.

Looks like an average 12" around the lake. If the wind comes from the north instead of the usual northeast, then Moultonborough Neck will not be sheltered by the Ossipees this time. Center Harbor might be sheltered by Red Hill. Otherwise, I would expect locally higher totals (15-18") in Tamworth, Sandwich, Gilford, and Alton.

If the 35+ mph sustained wind actually happens this far inland, I would expect a wind tunnel effect to set up along the Rt. 25 corridor in Moultonborough, where the wind will be forced between the Ossipees and Red Hill. The wind tunnel effect, if it happens, would increase the wind speed going through there.

I might also expect some wind enhancement along Rt. 11 in Alton Bay, IF the wind is from the north. A strong north wind would be forced "around the bend" by Mount Major, and wind speeds up when it does that. Rt 11 lies on that bend.

The same kind of effect may also occur on the eastern side of the Ossipees, near the intersection of Rt 16 and 25.

These locations, along with any exposed hill/ridge tops, are the areas I think are most likely to experience wind damage. This prediction is based on a NORTH wind.

As the storm begins to clear, wind will shift and come from the Northwest (Center Harbor to Alton.) We deal with that all the time. Everyone knows exactly what happens at his or her own location when we get hit with strong NW winds, because they're so common in fall and winter. Therefore I don't need to point them out.

As for an anemometer, a good place to shop online is www.ambientweather.com. If you'd rather shop in person, Robert E. White Instruments in Boston is the kind of business that's rare today -- honest, good service, sells quality stuff, puts customers first, etc. They are also online.
