MOUNTAIN WEATHER FORECAST



Time: 0930
 

The Snapshot:  Continued rain and snow showers today tapering off tonight.  Light passing showers with periods of clearing expected to be the norm for the weekend.

 
The Science:  Most of the significant weather will remain along the PNW coast as a low pressure system slides south.  Weak bands of moisture will swing through the Cascade Mountains over the weekend.  Little to no accumulation is expected.  The low pressure off the coast and a high pressure system developing over the interior Rockies will team up to pull warm air up from the south.  This could cause freezing levels to rise as high as 10,000’ on Sunday/Monday.


Interesting note:  One of the strongest hurricanes on record (Hurricane Haiyan Cat 5+) is making its way across the south pacific. The “super storm” hit the Philippines last night and is now tracking toward China.

 
4-7day Long Range:  Rain on Sunday with drier and warmer conditions during the first half of next week.
