... Wind Advisory remains in effect from 1 PM Friday to midnight
PST Friday night...
* winds... southwest 15 to 30 mph with gusts up to 50 mph.
* Timing... Friday afternoon and evening. Winds will decrease by
* Impacts... local strong wind gusts will break tree branches and
move unanchored objects. Scattered power outages will be
possible. Controlling high profile vehicles may be difficult...
especially along north to south oriented highways including
195 and 95.
A Wind Advisory means that wind gusts of 45 to 50 mph are
expected. Winds this strong can make driving difficult...
especially for high profile vehicles. Use extra caution.

Area forecast discussion National Weather Service Spokane Washington 254 am PST Friday Nov 28 2014 Synopsis... a rainy and breezy weather pattern will envelope the region going today, but snow levels will remain above pass levels for motorists traveling. The arrival of a very cold and windy Arctic front Friday night into Saturday will bring winter driving conditions to the mountain passes and much colder weather for the weekend. Cold conditions, with a few minor snow bearing weather disturbances, is forecast for the new work week. && Discussion... Today through saturday: the biggest change to the previous fcst was the issue a winter wx advsy for snow for Saturday for the cntrl Idaho Panhandle mtn zone (mostly Shoshone county) for significant snow accumulations down to the valley floors. This could be a potentially busy I-90 travel day back home following Thanksgiving. The Wind Advisory for today has not changed. Very mild temps and windy conditions are still expected today as we remain in the pre-Arctic cold front passage expected Fri nt. A nearly unidirectional vertical SW wind profile... with 40-50kt aloft...will help to provide very efficient mixing and Transfer of these higher speeds around 5k ft aloft to the sfc. Snow levels will remain very high today, but falling quickly to the sfc as the surge of very cold air behind the Arctic front works its way from north to south across ern WA and north Idaho Sat. The most tricky part of the fcst will be snow amnts. This front and associated upper wave will move through quickly and help to limit snow accumulations. Offsetting this somewhat will be respectable lg- scale forcing for ascent with the wave as well as a strong lower tropospheric upslope component of flow into the Idaho Panhandle Sat. Also, swe ratios (once the cold air mass fully arrives) will be at least 20-30:1, promoting heavier accumulations. And even moderately gusty winds would produce blowing snow and restricted visibilities where snow is expected. We'll have to watch the Camas Prairie of Idaho for significant snow accumulations Sat nt as the low-level flow veers to the northwest and enhances the upslope flow. Confidence is not great as far as snow accumulations for the Spokane area Sat. The majority of model guidance (which we've favored) shows the best pcpn threat ending very close to when the cold air moves into the area. We'll be watching the scenario closely, and adjust the snowfall fcst accordingly and as quickly as possible as soon as these snow ingredients allow US to fine tune the accumulations better. Bz Saturday night through Monday...the region will transition to a cold and dry weather pattern as a polar front swings south across the inland northwest. Gusty north winds will continue to be channeled down the Okanogan Valley Saturday night. The combination of very cold temperatures and windy conditions will result in wind chill temperatures of -15 to -20 f overnight. The strong surface pressure gradient fostering the elevated winds will slacken Sunday as the low pressure center moves off to the southeast and weakens. This will allow winds to diminish and become more terrain driven. High temperatures Sunday will be 12 to 15 degrees below seasonal normals. While most valley locations will be in the low to mid 20s, some of the northern valleys will remain in the teens during the day, then drop back near zero Sunday night. The large scale pattern will become more westerly by Monday. Without the reinforcing cold north winds, temperatures will start to moderate somewhat. A closed low off the California coast will drift east, acting to push the frontal boundary back north as a warm front. The 00z run of both the GFS and the European model (ecmwf) now keep this front mostly to our south with just the southeast zones under the threat of precipitation from this feature. The warm front will battle with the deep cold air in place. Some warm air may push in aloft but for now wet bulb temperatures remain below freezing throughout the day Monday so precip would likely fall as snow. Monday night through Thursday...the extended forecast has been trended toward the European model (ecmwf) which builds a foldover ridge over the region in response to the California offshore low. This is a drier forecast than the GFS which brings the moisture stream farther north in more zonal flow. There will be a very gradual warmup since winds will be light and mainly terrain driven with limited mixing potential. The ridge does not hang around for long. It will be pushed east once the coastal low moves inland during the mid- week period, bringing the next round of precipitation to the region. /Kelch && Aviation... 06z tafs: a developing storm system will bring mean increasing clouds and rain chances over the next 24 hours. The best chances will start late tonight into Friday morning around puw/lws. Chances will also come toward the geg to Coe areas by Friday morning, but the better threat here will be in afternoon and evening. Look for VFR conditions, with local MVFR/IFR cigs possible in heavier precipitation as Friday afternoon progresses into evening. The lowest precipitation threat will be over the Lee of the Cascades and deeper Columbia Basin, including eat/mwh. There is some potential for fog and stratus to develop overnight and early Friday around eat, but latest forecasts guidance suggests it may not be as deep if it develops at all. In the messy pattern, there will also be breezy and gusty winds, but these may be decoupled tonight and early Friday leading to areas of low level wind shear. By mid to late morning/afternoon the atmosphere begins to mixed again and gradients will tighten with the incoming low, leading to breezy conditions. Some winds gusts between 30 and 45 kts will be possible in the afternoon, especially over the expose taf sites including geg. Note: the visible sensor at eat is out of service so amendments to visible are not scheduled. The offending sensor replacement is on order and may be returned to service by Saturday. /J.
