The big interior Northeast snowstorm is underway with light to moderate snow now spreading across the region late Thursday AM.

It’s late tonight into Friday that things really fire up as a secondary low forms off Cape Cod and sees a 24mb pressure drop before reaching the mid Maine coast tomorrow afternoon.

As this coastal low winds up, so winds crank to gale-force and with a moisture stream sweeping up the coast and over the Gulf Stream, it wouldn’t surprise me if favoured upslope areas of New Hampshire and Maine pick up 30+ inches from this.

Expect blizzard conditions over southern New Hampshire and west/central Maine as winds gust 50-60 mph.

Let’s not forget the lake effect. Bitter NW wind crossing warm lakes = major snowfall and blizzard conditions!
