MOUNTAIN WEATHER FORECAST

Time and Day: 1200 Friday

The Snapshot:  This clear, beautiful weather will continue through the middle of next week.  Cooler temperatures will begin to filter in on Sunday.  
 
The Long Range:  There will be a chance of snow late next week.     

The Science:
Temperature = 40f,  Rh = 75%, barometer = 1024mb and holding steady.

High pressure over the PNW will continue to dominate the weather pattern through the weekend.  Things begin to slowly change early next week as the cooler unstable air begins to make its way in from the north.  

Pressure gradients will begin to tighten along Cascade Crest on Sunday as the temperature east of the mountains fall.  This will likely produce some gusty easterly winds on Monday.      

Colder temperatures and a chance of snow are beginning to show up on the long-range models. Stay tuned as those detail mature.
