MOUNTAIN WEATHER FORECAST

Time and Day: 0800 Saturday

The Snapshot:  Continued clear but a bit cooler today and tomorrow.  Clouds roll in on Monday with rain/snow on Tuesday.

The Science:  The weather pattern will continue to be clear and dry with cooler air filtering in from the north.   A marine push will bring cooler air west of the mountains and eventually clouds and moisture to the Cascade early next week.   

The Long Range:  A low-pressure system developing in the Gulf of Alaska will push the high pressure east of the State on Tuesday.   Much cooler air with some precipitation (rain and snow) will begin on Tuesday.

Precipitation Ending at 4am:

Today 24hr water = 0 Snow = 0

Tomorrow’s 24hr water =  0 snow = 0

Trend and Timing:
Dry until Tuesday.


24hr temperature ending at 4 am tomorrow: 
                                     
Low:  34   High: 50
Freezing level: 9000’ - 6000’

Trend and Timing:   
Freezing levels will remain well above Pass level.  Cooler air aloft should allow early morning temperatures to dip to freezing for the next several days.

 
24hr Winds (mph) ending at 4 am tomorrow:
Base: 0- 5 NW
Ridge Top: 0- 10 WNW

Trend and Timing:
Light northwesterly flow will continue through tomorrow.
