A Heat Advisory is in effect from Tuesday through Thursday and Hot and Humid conditions exist across the San Joaquin Valley. Will expect the Heat Risk to start at Moderate Levels and rise to Major levels during the Mid-week event. High temperatures during this time will range from 102 to 108 degrees and overnight low stay in the mid to upper 70s. Stay indoors in Air Conditioning when possible, and drink water to stay hydrated.

Sunday, July 12, 2026 @ 3:50 AM PDT - High pressure over California will continue to bring above average temperatures this week. Triple digit heat persists over much of the lower elevations. Reduce time outside and take steps to reduce risk of heat illness if outdoors!

A Moderate Risk for Elevated Fire Danger will exist across portions of Central California. In particular, the Coastal Range (West Hills) and a large part of the San Joaquin Valley, all north of Kern County. These areas will observe strong wind gusts in the range of 20 to 30 mph and relative humidity down to 15 to 25 percent. These conditions will allow for elevated fire danger as the dry grasses will experience enhanced ignition potential during the Wednesday and Thursday time frame.

A disturbance passing through the Pacific Northwest around Mid-week will generate strong winds over portions of Central California. These strong winds, accompanied by dry conditions (low relative humidity), will produce elevated dry danger conditions across Central California. Along with dry grasses, fire starts will have a high potential during the mid-week period.
