CALIFORNIA - You might not need a thermometer to tell you it’s going to be hot this weekend when just stepping outside feels like preheating the oven. That’s what millions across California and parts of Nevada are gearing up for, as forecasters warn of a severe heat wave arriving Friday and lasting into early Sunday.

The National Weather Service has issued extreme heat watches from the Central Valley to the Sierra foothills, warning of triple-digit temperatures, some possibly exceeding 109°F. High-risk areas include Fresno, Bakersfield, Redding, and Sacramento, where overnight lows may offer little relief, hovering in the mid-60s to mid-70s.

Coastal regions will dodge the worst of it with cooler 60s and 70s, but inland residents are advised to stay indoors, hydrate often, and check on neighbors.

Whether you're inland or in nearby Nevada (Las Vegas and Death Valley are also under alert), this is one of those weekends where sunscreen and shade aren’t optional.

Check in with ANUK as this pattern develops, and don’t forget to drink water, not just coffee.
