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.
