Mountain Weather Forecast Update.

Mountain Weather Forecast Update.
The current cloud deck is thinning, and that trend will continue through today.  Tomorrow will be dry with sun breaks and very high freezing levels (10,000’+).  There is talk of record high temperatures tomorrow with west slope temps hitting 700f.    With some luck and good radiation cooling (a clear night), low temperatures will drop to the mid to lower 30’s during the early morning hours.

Saturdays storm details as of now:
Many changes are in the works as the approaching system matures; I would expect more changes with tomorrow’s update as well.  For now:
Rain arrives after 4am Saturday morning with .75-1” through the day.  (Joel’s optimistic gut may be right) 
Precipitation ends after 7pm Saturday night.
Sunday is trending dry with the main system now tracking south of Stevens Pass.  Freezing will struggle to drop below 4000’. Therefore, no snow is forecasted at this time.

Long-range: 

Long-range models continue to have little consistency, so confidence is low here as well.  With that said, a split flow pattern develops early next week with mostly dry weather forecasted. Temperatures continue to be on the warm side, so no significant snow is expected for the next 7-10 days.
