.DISCUSSION...

Through today and tonight, expect skies to start off clear before
clouds begin to move in ahead of our next weather system. Warmer
and moisture laden air will begin to push into the area for
Saturday, which may result in some localized snow that changes to
rain by mid morning. Winds will accompany the arrival of the
warmer air overnight tonight and through the day on Saturday, with
wind gusts to around 60 mph possible at Logan Pass tonight and
through the day on Saturday. Winds weaken a bit on Sunday, with
gusts up to around 45 mph Sunday afternoon with just a 15% chance
of a rain shower.
