MOUNTAIN WEATHER FORECAST

Time and Day: 0600  Friday

The Snapshot:  More of the same today; mostly dry with a broken layer of clouds lapping up against the summit.  There will be a chance of a dusting of snow tomorrow night.

The Science: Temperatures will be a bit cooler today as east flow strengthens a bit.  A weak low pressure system is expected to track up along the west slopes of the mountains tomorrow bringing a bit of light snow to Stevens Pass.  No significant accumulation expected.

Long Range:  High pressure strengthens on Sunday for clearing and more dry weather for beginning of the week.   Long range models now have a system breaking through the pressure ridge some time on Wednesday. Stay tuned as those details become clearer.
