How hot will it get in Northern California? Here’s what to expect in coming heat wave

Northern California is gearing up to confront its second heat wave of the year, nearly two weeks from its first.

The National Weather Service is forecasting scorching triple-digit temperatures for the Sacramento region and issued an Excessive Heat Warning Thursday morning. The warning goes into effect at 11 a.m. Saturday and lasts until 11 p.m. Sunday for areas including Modesto, Stockton, Shasta County, the Sacramento Valley, Carquinez Strait and Delta region.

Temperatures could go up to 114 degrees in Redding and Red Bluff.

“Hottest temperatures are expected over the weekend with widespread Major Heat Risk and areas of Extreme Heat Risk. Warmest overnight lows will be in the foothills and northern Sacramento Valley,” the service stated in its warning, adding that rivers and lakes are still running cold and fast.

Certain people will be most vulnerable to the heat, such as pregnant women, newborns, children, the elderly and those with chronic illnesses. The service is advising that everyone stay hydrated with water, stay in air-conditioned buildings or indoors, and don’t leave kids or pets in cars.

Individuals should also reschedule any strenuous activities to the early morning or evening, and wear light and loose clothing.

What’s the forecast?

The Sacramento area will see highs around 97 degrees Thursday and a low near 62.

Friday kicks off triple-digit temperatures with a high near 106 and a low around 66 in eastern Sacramento County. Saturday’s high is near 110 and Sunday’s is around 108 across the capital region. Lows for the weekend are forecast near 70 degrees.
