A major shift in the weather begins Wednesday night into Thursday as the first in a series of storms sets up for periods of strong winds, rain, and mountain snows, which should be heavy at times. These rainy periods are expected to continue at times through the weekend into Monday, then give way to improving conditions Tuesday of next week.
