Snow is falling in the Sierra on Monday morning and will increase during the day. Idaho is getting deep near McCall, while the Tetons and Wasatch appear to reap the highest totals in the next 24 hours. By Tuesday, you can chase the storm from CA to either of these regions for deep powder. A few spots in MT score deep, too, with Colorado getting the wrung-out leftovers.
Locally heavy rain moved over New England on Sunday night and will move offshore throughout the day on Monday. Recent model trends suggest that some snow on the backside of storm may develop and bring a coating to an inch of new snow.
Heavy snow fell across the West over the weekend, and new storms will arrive every 1-2 days this week with significant snow totals expected for many areas. Late-season conditions will remain excellent with additional powder days on the way.
