Area Forecast Discussion National Weather Service Spokane WA 539 AM PDT Tue Sep 29 2020

SYNOPSIS. High pressure will be anchored over the West this week bringing our region a prolonged period of warm and dry weather. Temperatures will be above average through the weekend. Afternoon highs in the upper 70s to low 80s will be common from Tuesday through Sunday.

DISCUSSION.

Today through Thursday: No significant changes have been made to the forecast for the next several days. A high amplitude ridge/trough pattern has been established over North America and will remain in place through at least the weekend. The western United States will experience a prolonged period of warm and dry weather under strong high pressure while the central and eastern states will be under the influence of a cool trough. For eastern Washington and north Idaho we expect high temperatures in the upper 70s and lower 80s TUE through THU which is about 10 degrees above average. Overnight lows will be seasonably cool with 40s and low 50s. We will be keeping an eye on the plume of smoke generated by the California wildfires. The HRRR Smoke model advects mid and high level smoke up the coast today and across Washington state on Wednesday. At this time, the model keeps much of the smoke aloft above a subsidence inversion roughly 5000-6000 feet above the surface. This scenario suggests that our skies will become milky or grey through the day Wednesday into Thursday. How much smoke mixes down to the ground is unclear at this time, but a repeat of the terrible air quality we had earlier this month is not anticipated. The active fires are further away and collectively producing less smoke. /GKoch

Friday through Tuesday: Very little, if any, change to the forecast or the general theme from the past several discussions. Temperatures will remain 10-15 degrees above normal through the weekend with only a few high clouds streaming overhead Sunday associated with a weak upper level disturbance. Rain chances have diminished late in the weekend so the expectation is that there won't be any precip over the Inland Northwest through the weekend and into early next week.

The ensemble mean is hinting at the ridge breaking down mid to late next week (Oct 7-8) thanks to a deepening trof along the BC coast. Until then, expect mostly clear skies and well above normal temperatures.

Given the stable pattern, smoke or haze may be apparent during this time frame too. We'll have a better idea of smoke impacts in a few days as the smoke from California arrives. Whatever arrives has a good chance of sticking around through the first week of October. /AB

AVIATION. 12Z TAFS: With the exception of some valley fog in the Idaho Panhandle and far northeast Washington this morning, the Inland Northwest will have clear skies and light winds today, tonight and Wednesday. Our fog prone valleys will have a good shot of more fog again Wednesday morning in places like Bonners Ferry, Sandpoint, Priest Lake, and the Pend Oreille River valley. /GKoch

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.
