August 23, 2019 – Above average temperatures are expected into next week. Dry weather pattern continues.


Well above normal temperatures are expected through the forecast period as strong high pressure strengthens over NorCal. In addition, the ridge will keep interior NorCal under dry conditions.

Valley locations should see temperatures in the upper 90s to around 106, while highs in the low 70s to mid 80s are expected over the mountains through the forecast period.

Warmest readings are anticipated over the N Sac Valley, where triple digit highs will be possible each day.

The aforementioned highs could result in heat-related illnesses among sensitive groups. Therefore, those that are sensitive to heat should hydrate adequately, avoid long exposures in the afternoon sun, and dress appropriately while using sunscreen.

Overnight lows could provide some relief from the hot daytime temperatures, with Valley morning readings mainly in the 60s through the weekend.

Extended Discussion (Tuesday through Friday)

Upper ridging from the Desert SW will keep triple digit heat over the northern half of the Sacramento Valley Tuesday. Upper 90s expected elsewhere in the Central Valley. Ridge axis begins to shift east Wednesday as upper low off the CA coast progresses. Wave weakens as it lifts across the CA/OR border Thursday so dry weather expected. Main impact will be cooling midweek with highs forecast in the 90s throughout the Central Valley Thursday and Friday.
