Today will feature continued cool weather as westerly winds around the southern side of our windstorm from Monday continue to push cool Canadian air through the area. A weak disturbance embedded within the flow around that low is moving through MA this morning. The northern edge of that system is bringing some light snow to southern NH. It’s possible for some towns right along the MA border to pick up a dusting-1″ in the next couple hours before the system quickly moves offshore.
Any snow that does fall will melt quickly as the sun comes out behind that disturbance and temps warm into the mid/upper 40s outside the mountains (where upper 30s/low 40s are expected). Those warmer temps will support some weak instability as very cold air moves in aloft. As a result, expect clouds and showers to pop up around/after noon. Those showers will fall in the form of snow for most of the area though a mix of rain/snow/graupel is more likely along the coast. No accumulations are expected from these showers.
Both clouds and showers will fade around sunset.
