August 26, 2018 – Cooler and dry weather expected through next week. Areas of smoke and haze will continue, especially near wildfires.

Discussion (Today through Wednesday)

Weak trough positioned over northern California overnight based on water vapor and model analysis. Some light visibility reductions due to smoke and haze were reported for several valley and mountain observation sites, but mainly for Redding and along the eastern valley up against the foothills.

Otherwise, mostly clear skies overnight across the interior. Hires models continue to hint at some low level marine clouds pushing into the Sacramento area and surrounding delta influenced areas during the morning hours through midweek as increasing onshore flow results from troughs passing aloft.

With a slight presence of a mid level 700 mb jet today, gusty winds over the Sierra are possible Sunday afternoon into Sunday evening. The next air mass will drop southward for the beginning of the workweek, which will lead to cooling temperatures and increasing onshore flow through mid week. Dry weather will continue with smoky conditions near the wildfires and hazy conditions elsewhere.

Extended Discussion (Thursday through Sunday)

Weak upper trough will maintain dry weather with temperatures near or slightly below average later this week into next weekend.
