Tuesday morning with higher snow levels. A second system will pass
through Tuesday into Wednesday. Expect snow levels to lower

strong winds, especially near the summit. Another round of snow is
likely Thursday into Friday before precipitation tapers back into
the weekend. Temperatures will drop going into midweek through the
weekend.
