Today will feature (very) light snow as a weak storm system slides by to our south. Flakes are already flying across southern and western parts of the area this morning, and that’s generally where activity will be concentrated today. I’m not expecting more than an inch of accumulation this morning through the midday hours. By early afternoon, an approaching upper-level trough and developing ocean-effect should turn up the heat on snowfall rates especially along the coast south of Portland. This may allow for a period of moderate snow to drop another couple inches here while the rest of the area continues to see light snow (except for the northern mountains where flakes will really struggle to make it to the ground).
So in total, if you’re up north of Route 2, expect a dusting to an inch, if you’re in the NH mountains, foothills, or coastal plain north of Brunswick, expect 1-2″, and if you’re in the sweet spot from Casco Bay ish down to the NH Seacoast and points 30-50 miles inland, be prepared for as much as 2-4″. A couple really lucky spots may be able to push 6″ if everything sets up right, but with the recent trend of disappointing storms in setups like this, I remain skeptical.
Snow will wind down from west to east this evening. High temps today will range from the low 20s up north to around 30 right along the coast south of Portland.
