714 FXUS66 KOTX 111726 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1026 AM PDT Thu Jul 11 2024 .SYNOPSIS... While the extreme heat has eased, it will stay hot, dry and locally breezy through the week. Areas of haze and smoke will linger over the Inland NW from local fires. && .DISCUSSION... Today through Wednesday: Temperatures will be 5 to 10 degrees cooler today, staying consistent over the next week, with only slight fluctuations by a couple degrees. Flow will stay mainly zonal with a light ridge building in on Sunday, allowing for continued sunny skies, hot temperatures, and slightly increased winds. This zonal flow vs. the normal high pressures we have won`t allow for the days with no wind, although a nice light breeze with this heat may feel more enjoyable. Nighttime lows will generally be in the upper 50s to mid 60s, allowing those without AC to open up their house at night. Zonal flow will also keep pushing smoke from the Pioneer Fire and additional fires in Oregon towards Eastern WA and the ID Panhandle. Expect hazy skies to continue, with period of smoke making it to the surface from time to time. Most of the smoke will stay elevated, with decreased air quality around Lake Chelan. The latest air quality readings and smoke outlooks can be found at fire.airnow.gov. /KM && .AVIATION... 18Z TAFS: VFR conditions continue. Local reductions in visibility possible near and downwind of Lake Chelan due to smoke from the Pioneer Fire. Anticipate locally gusty. The northerly winds in the Okanogan Valley should subside by 20z, while westerly winds will pick up across the Columbia Basin, Palouse and Spokane area after 20z and in the Wenatchee area after 00z. rfox.
