Gradual Warm-Up Into Next Week

Moderate Heat Risk this Weekend

Minor Fire Risk for Valley and Foothill Areas

Stay Safe Around Area Lakes and Rivers

The active pattern for the Sierra Nevada will continue today, with another 15 to 30 percent chance for scattered thunderstorms as mid-level moisture combines with warm air upsloping from the valley areas. Erratic winds, small hail, and localized heavy rainfall may accompany these storms in addition to cloud-to-ground lightning.

Upper level flow becoming more south-oriented into the weekend has a low to medium chance to bring triple-digit temperatures back to the San Joaquin Valley. These temperatures will bring about a moderate risk of heat-related illnesses to those sensitive to heat, such as older adults (65+), infants, athletes, outdoor workers, those without effective cooling, and those with chronic diseases. There is some risk to the general population.

Moderate Heat Risk is expected for Saturday and Sunday across the San Joaquin Valley with maximum temperatures approaching 100 degrees. This level of heat can cause heat-related illnesses to those sensitive to heat, such as older adults, infants, athletes, outdoor workers, and those without effective cooling. Stay hydrated, wear lightweight, light-colored clothing, and reduce time spent outdoors or stay in the shade.

A gradual warming trend into next week will cause drier conditions to propagate across central California. Minimum Relative Humidity is expected between 15 and 25, and wind gusts could reach up to 20 mph. Take precautions to mitigate fire development and spread.

With near-triple-digit heat anticipated for the weekend, keep in mind that area lakes and rivers are still running cold. Warm air temperatures do NOT mean warm water temperatures! Rivers in particular are running swift as dam water releases are increasing across the region. Continue to take precautions around waterways!
