MOUNTAIN WEATHER FORECAST

Time and Day: 0700 Saturday
The Snapshot:   Breezy, cooler temperatures with light passing rain showers and sun break today; mixed rain and snow tonight with a drying trend beginning tomorrow. 
The Science: Satellite imagery shows spotty showers with patchy clouds over the Cascades this morning.  Some upper-level ridging will provide some clear periods between the showers for most of today.   This ridging will also play a part in keeping the bulk of the moisture west of the crest tomorrow.   Therefore, expect the weekend to have a mixed bag of sun, rain, and snow.  Fitting for the final weekend of the season. 
The Long Range:  Next week will be mostly dry with cooler temperatures.  
P.S. This will be the last official Mountain Weather Forecast for the season.  Have a great summer everyone.
Precipitation Ending at 4am:
Today 24hr water = .25-.5  Snow = 0-2
Tomorrow’s 24hr water = .25 snow = trace

MOUNTAIN WEATHER FORECAST

Time and Day: 1000 Friday
The Snapshot:   Cooler with periodic rain showers today and tomorrow; mixed rain and snow for Sunday.
The Science:  A low-pressure system off the coast of Oregon will spin bands of showers north today and tomorrow.  Cooler air aloft will also begin to invade, gradually lowering freezing levels through the weekend.  A cold front will bring more steady mixed precipitation and cooler temperatures on Sunday. 
The Long Range:  Next week will start out partly cloudy, dry and cold with some light rain showers expected towards the end of the week.
Precipitation Ending at 4am:
Today 24hr water =  .25 Snow = 0

MOUNTAIN WEATHER FORECAST

Time and Day:  0800 Thursday
The Snapshot:  Clouds roll in today with a chance of light rain and possibly a thunderstorm or two.  Cooler with rain starting tomorrow and lasting through the weekend.  
The Science:  Surface temperatures peaked around 650 yesterday and should climb into the 600 again today.   A cold unstable air mass begins to push in tomorrow with rain showers developing through the weekend. With the cool, moist air hitting the warm, dry air, cumulus build up with thunderstorms will be possible.
Rain showers begin tomorrow and will last through Saturday. More steady light rain can be expected on Sunday.  It doesn’t appear that temperatures will not be low enough to get any snow accumulation, but there could certainly be some snow mixed in.
The Long Range:   Next week will be cooler with periodic rain showers throughout.  
Precipitation Ending at 4am:
Today 24hr water = .10 Snow = 0
Tomorrow’s 24hr water = .25 snow = 0
Trend and Timing: Rain showers tomorrow and Saturday.

MOUNTAIN WEATHER BRIEF

Time and Day: 0900 Wednesday
The Snapshot:   Clear and warm again today with a chance of a light rain shower or two tomorrow.   Rain or even snow can be expected over the weekend.
The Science:  With another new record high temperature for April being set at Sea-tac this week, (890 ) it’s hard to imagine that it could snow.
A strong low-pressure system developing in the Gulf of Alaska will push a vigorous cold front through the region on Friday.  Freezing levels are expected to drop below 4000’ late Friday night with this system; therefore, expect rain and snow throughout the weekend.
The Long Range:  Next week will start out dry and cool with another batch of mixed snow and rain expected on Tuesday/Wednesday.

MOUNTAIN WEATHER FORECAST

This week’s weather forecast has changed a bit since Saturdays forecast. 
The Science:  High pressure over the PNW will block and split any incoming disturbance for all of this week.  Therefore expect mostly dry and clear weather with seasonally average temperatures throughout the week.
The Long Range:  Some light rain with cooler temperatures is expected for the final weekend of the ski season.
Have a great week.

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

MOUNTAIN WEATHER FORECAST

Time and Day: 0800 Friday
The Snapshot:  Hit repeat today with sunshine and temperatures once again in the mid to upper 50’s.  A cooling trend begins tomorrow.   The steeps are sliding in the afternoon heat (snowpack is isothermal) so watch it out there.
The Science:  Washington State is nestled between two strong high pressure ridges; one to the east and one to the west.  The western ridge is expected to drift over the region over the next 24-48hrs.  Cooler air from the north will start to bring freezing levels down a bit. Hopefully, that will help firm up the snowpack a bit.
