I live in the Upper Valley and we seem to always end up with slightly lower totals than very nearby (Lebanon/Hanover area). Assume it’s due to being east of the Greens and in a river valley, but you have a pretty detailed, small zone carved out in this area and wonder what you see that leads to this specific location/wrinkle. Otherwise appreciate the work! Guess we’ll see how it all pans out pretty soon- looks like a lot of snow in a hurry.

So that featured I drew into the grids was intentionally done in each forecast for this event based on meteorologist experience (a combo of going to school at Lyndon State and forecasting for the area for numerous years). The reason behind that swath of lower totals stems from SE winds forced over the Kinsman-Cannon Range & Garfield Ridge, which is called downsloping. This dries out & warms the environment locally, which is more hostile to adding up precipitation there in those regimes.
