SYNOPSIS. The early season snowstorm will wind down this evening. Cold wind will develop overnight and continue on Saturday with the arrival of unseasonably cold air. Low temperatures in the teens will be common Saturday night and Sunday night potentially breaking records. Temperatures begin to rebound Tuesday as a high pressure starts to move into the area.
DISCUSSION. Tonight: Early season winter storm is making its impact in some areas of the Inland NW, mainly from the Methow Valley to the Silver Valley, including Republic, Colville and the Spokane metro area. Snowfall intensity has been hard enough to overcome the melting road temperatures, but areas with light snow have generally just had wet roads. After 5pm, the heaviest snow should shift into the Palouse and southern Panhandle where it will continue until midnight before changing to showers. Temperatures are warmer there which would mitigate snow accumulation. But road temperatures will likely cool with the setting sun which could allow for more road accumulation.
Cold northeast winds will develop behind the snow later tonight. For the roads this will be a dicey competition between evaporation and freezing. The post-storm winds will be rather dry and should evaporate much of the moisture on the roads. But can all of the moisture evaporate before it freezes? Suffice to say there could be some icy roads for Saturday morning. RJ
Saturday through Friday: The last of the snowfall will exit the ID Panhandle through Shoshone County in the early Saturday morning hours. Saturday will be quite windy with north winds and gusts up to 25-35 mph through the Okanogan Valley and a majority of the Columbia Basin. Areas in the Northern ID Panhandle such as the Purcell Trench may see gusts up to 40 mph. Strong wind gusts will result in wind chills in the teens to single digits. Hypothermia will be a significant concern over the next few days if outside without proper protection. Blowing snow may be a potential hazard for the Northern ID Panhandle on Saturday, but snow may be a bit too heavy for the winds to pick it up off the ground.
As the upper level low continues to move southeast out of the area, an upper level ridge builds offshore putting the Pacific Northwest in a northerly to northwesterly dominated flow. This allows for a cold, dry, Arctic airmass to push into the region. Extremely cold temperatures in the teens and single digits are expected for much of the region, with a good possibility for breaking record lows and record low highs. The low temperature Sunday morning in Spokane is currently forecasted to be 11 degrees, which would beat the record of 12 degrees that was set in 1919. Monday looks to be around the same, but the current record is 19 set in 1978. We will also likely see record cold high temperatures with most of the area forecasted to reach only the low to mid 30s on Sunday and Monday. Winds will be lighter on Sunday through the end of the work week, as the offshore high pressure begins to push inland. These conditions hint at a possible air stagnation event beginning Sunday. Any burning under these conditions would impact air quality.
Temperatures begin to rebound on Tuesday as the offshore ridge begins to push further inland. There are a decent amount of discrepancies between models and their ensembles on the duration and breakdown of the ridge. Some models have it out of the region by Wednesday, and others have it through the end of the work week. A longer duration ridge would keep the air stagnation pattern in place, but a flatter ridge pattern would allow for a wetter pattern. Regardless of the solution that pans out, temperatures for the latter half of the week will be significantly warmer than what is expected on Sunday and Monday with highs in the mid 40s to mid 50s and lows in the mid 20s to mid 30s.

AVIATION. 00Z TAFs: Snow will wind down tonight as the winter storm exits to the region. IFR conditions north of highway US-2 should improve this evening as snow comes to an end. IFR cigs in the Spokane metro area will take longer to lift, closer to around 10Z. The Palouse along with the central/southern Panhandle will be the last to improve with some areas of IFR lingering into Saturday morning. Gusty north/northeast winds will develop behind the storm system and continuing all day Saturday. RJ

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
