A north-by-northwesterly flow will help smoke waft across the region and thicken through Saturday. Unsettled skies remain through the middle of the week with the smoke creating a weak cap to prevent thunderstorms development for most of Eastern Washington. Thursday night into Friday morning the stalled trough overhead will fill and slide east as high pressure builds into the region quickly through Saturday. Another trough is set to flatten the ridge from the northwest by the beginning of next week to keep temps near average with more unsettled skies after Sunday. Temps will cool to the low 80s and upper 70s for the beginning of next week before warming back to the mid 80s after a cold front passes from the southwest Saturday night/Sunday morning.
