Area Forecast Discussion National Weather Service Spokane WA 307 AM PDT Thu Oct 1 2020

SYNOPSIS. Warm and dry weather will persist across the Pacific Northwest through the weekend and well into next week. Skies today will likely have a hazy appearance as a passing upper level disturbance directs California smoke into our region.

DISCUSSION. Thursday and Friday: The main weather focus over the next 2-3 days will be the influence of smoke aloft drifting in from the west - southwest. High resolution forecast models have begun to get a handle on how the smoke will move in and where it will move in across Washington. The smoke near the surface looks to be pretty minimal and should remain mostly lofted at or above 10k feet above the surface. This should result in minimal impact to air quality. Those folks that are more sensitive to smoke and particulates may still notice a difference. The smoke aloft looks to begin drifting into southwest Washington between Mount Rainer and Mount Hood late this afternoon and makes a broad east- northeast expanse into the south- central Columbia Basin through Friday morning.

The shift in the smoke trajectory is due to the ridge being shifted south slightly. A weak shortwave that will slide down the eastern side of the ridge (along the Idaho/Montana border) Friday will shift the winds aloft to more northwesterly. Daytime temperatures will be affected very little and should remain about 10 degrees above seasonal normal for the start of October (normal is 67-68F for Spokane).

Saturday and Sunday: A deep Low in the Aleutian Islands will begin weakening and allow the amplified ridge across the PacNW begin to flatten and weaken over the weekend. While the ensemble model suite has been pretty consistent outside of slowing this feature down a bit, the deterministic counterparts are a bit different, showing differences among each other and timing and strength variations. The shortwave feature still is being advertised but most of the precipitation looks to remain north of the US/Canada border for Sunday. A baroclinic front will help to cool temperatures down late weekend into the early part of next week. Perhaps help it feel more like Fall?

Monday through Thursday: Pretty benign weather through at least the first part of next week with a flat ridge of high pressure. Models begin to differ to what extent this lingers through late week. The ridge looks to be less strong and more fluid. A suggestion of a more direct-approaching trough from the west looks promising sometime Thursday with all guidance suggesting precip smattered across the Cascades and spilling into eastern Washington. Of course ahead of this southwest winds may bring in some form of haze/smoke depending on the status of wildfires in Northern California and Oregon. Most of this remains to look elevated with very little impact on surface visibility or air quality. /Dewey

AVIATION. 12Z TAFs: VFR conditions will continue. Smoke will persist aloft but should remain at or above 10k ft AGL. Some high clouds will move in across northeast WA and northern ID airports but should remain above 10k ft as well. Patchy fog developing early this morning at DEW and SZT may spread to other nearby smaller airports or northern valleys. Occasional reduced visibility from controlled burning and smoke may impact areas near Lewiston, Pullman, or the Nez-Perce area. /Dewey

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.
