.DISCUSSION...Snow will become more showery today as the focus for
precipitation shifts to the south and east. A few showers may
persist tonight and Saturday in northwest flow. The strongest
winds have subsided but will continue to be gusty at times
through 9-11am before weakening. Those winds turn northerly late
this afternoon and remain for that general direction through
Saturday. The period of strongest winds from this direction will
be from midnight tonight through mid morning Saturday. We should
see snow returning Sunday night and Monday, with snow forecast at
all elevations.
