814 FXUS66 KOTX 011644 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 944 AM PDT Thu Oct 1 2026 .KEY MESSAGES... - Temperatures gradually trend warmer heading into the weekend. Afternoon highs peak in the 70s to low 80s Saturday through Monday. - Mainly dry conditions are forecast with the exception of shower chances for the North Cascades Thursday and Friday. && .SYNOPSIS... Temperatures will trend warmer through the end of the week, rising into the 70s and low 80s by the weekend. Conditions are looking benign through the first week of October with mainly dry conditions and light winds. && .DISCUSSION... Today through Friday: Zonal westerly flow prevails across the Inland Northwest through Friday, maintaining the quiet, unimpactful weather pattern. A weak wave embedded in the zonal flow will bring passing high clouds regionwide today and low chances for showers across the North Cascades. Any showers that develop over the North Cascades will be very light with chances for measurable precipitation (greater than 0.01 inches) ranging from 20 to 30 percent. Elsewhere, conditions will remain dry. Temperatures today will peak in the mid 60s to low 70s, then will warm by around 5 degrees for Friday, rising into the upper 60s to upper 70s. While afternoon temperatures will be warm, mornings will still feel crisp and fall-like thanks to radiational cooling under mostly clear skies and light winds. Low temperatures will range from the upper 30s across the sheltered northern valleys to the low 50s for the warmest spots further south including Wenatchee and Lewiston. Saturday through Monday: An upper level ridge builds over the weekend, and as the ridge builds, high temperatures will continue to climb. Afternoon highs will peak Saturday through Monday in the mid 70s to low 80s, 10 to 15 degrees above climatological normals for early October. Tuesday and Wednesday: Ensembles generally agree on a low pressure system dropping into the Gulf of Alaska by the middle of next week, flattening the upper-level ridge across the Inland Northwest and transitioning the flow pattern back to a zonal regime. Increased moisture moving in aloft will bring some clouds over the northern mountains, but the forecast remains dry. High temperatures will cool slightly, returning to the low to upper 70s across the lower elevations. /Fewkes && .AVIATION... 18Z TAFS: High clouds will persist regionwide through the afternoon and evening, clearing overnight into Friday morning.
