Above average temperatures are expected through the week, with highs well into the 90s with some triple digit temperatures possible by the end of the week. Otherwise the forecast remains dry and occasionally breezy. Wildfire smoke will also continue to impact portions of the Inland Northwest.
Tonight into Wednesday: Bands of mid and high level moisture will rotate around broad high pressure centered over the Central Rockies. Eastern Washington and north Idaho will be on the northern periphery of the monsoonal moisture drawn northward around this broad high. While scattered showers occur across Oregon, look for bands of mid and high clouds in our region. The moisture and instability isn't expected to be as deep, but may be sufficient to produce radar returns from time to time over places like Lewiston, Ritzville, Moscow, and Kellogg. With an abundance of dry air in the lowest eight to ten thousand feet, most rain will evaporated prior to reaching the ground. Our forecast carries a chance for sprinkles, but a few spots may experience brief periods of rain drops larger than sprinkles but they won't last long. Lightning isn't completely out of the question across far southeast Washington or central and southern portions of the Idaho Panhandle for the next 48 hours. Forcing and elevated instability on model soundings are weak suggesting a marginal environment for updrafts supportive of lightning, but the probability is low enough not to include in the forecast at this time.
There should be enough mid and high clouds Tuesday and Wednesday to suppress afternoon temperatures a bit. Low 90s should be common from Spokane to Sandpoint to Kellogg to Pullman to Ritzville under cloud bands. Fewer clouds further north will likely lead to highs in the mid to upper 90s around Colville, Omak, Chelan and Wenatchee.
We don't have good news for the communities in north central and northeast Washington experiencing smoke. No rain is expected for the rest of the week. The wind regime the next couple of days is not expected to change much either. The Methow Valley will continue to experience the worst air quality as thick smoke channels down the valley with the evening drainage winds and remains trapped until the morning inversion lifts around noon. /GKoch
Thursday through Sunday: With the ridge axis positioned along the eastern fringe of our area into western Canada, our temperatures will slowly increase Thursday through Saturday, topping off in the lower 100s for much of the area on Saturday. Saturday and Sunday mornings will be quite warm with lows in the upper 60s and low 70s. This reinforces the concern for heat illness this weekend.
As the Pacific Low and trough move inland during the weekend, the pressure gradient between western and eastern Washington will tighten, and instability and moisture are progged to increase -- this will culminate in some shower/thunderstorm chances and breezy winds on Sunday. Sunday will also be cooler; our current forecast has Spokane hovering right around 95, but we could see temperatures in the lower 90s. Haze and smoke will continue to impact the area throughout the period, particularly for areas close to wildfires. RC
AVIATION. 06Z TAFS: The most significant impact to aviation will continue to be limited visibility due to wildfire smoke. The fires producing the most concentrated smoke are in the north Cascades and over north central WA, including the Methow Valley. Visibility around these mountains will be limited at times to IFR. Limited visibilities are also forecast for some TAF sites, occasionally to MVFR. Moisture coming in the southwest flow will bring some thicker middle to high clouds over SE WA and lower ID, including a limited chance for showers. The best chances will be toward KPUW/KLWS. /KD
