The Western U.S. will see a quieter period of weather mid-week, while farther north, a storm will bring heavy snow to the coastal ranges of Northwest BC and Southeast Alaska. The East will see another storm but warmer air arriving will result in a transition to rain through Thursday afternoon for most areas.

A cold front will move across the East on Thursday night with another nice round of snow showers to follow through Friday, favoring New England and New York.
A moderate storm will also move across the West on Friday, but confidence is low in terms of the storm track with the Northwest and Northern Rockies seeing the best chance of snow, while snow potential for the Sierra and Central Rockies is less certain.
