What contributes to the little pockets of lesser snowfall in swarths of greater snowfall? Geographical terrain features?

For example the line of lower wind/snow that seems to stretch from Nashua through concord to Littleton right up the center of the state, why are these totals seemingly lower? Also curious

A good question! The rationale for both is as follows:

  1. Littleton: strong ESE winds Saturday morning will downslope over the Kinsman-Cannon & Franconia Range spines. Downsloping winds dry & warm the air locally downrange of this action, or locations immediately to the NW of Sugar Hill.
  2. Nashua: The depression there is for the potential for sub-par thermal profiles dramatically lowering snow ratios, with multiple windows where wet snow changes to sleet.
