Excessive Heat Warning period extended through Friday evening

The National Weather Service has extended an Excessive Heat Warning period that was originally set to lapse on Tuesday.

The warning period will now cover the rest of the week through Friday evening, forecasters said.

The extension is based on new forecast models that indicate triple-digit weather will linger in the region longer than previously thought. When the Extended Heat Warning was originally issued, it was set to expire near the end of Labor Day.

Locally, the communities of Dixon, Rio Vista and Vacaville are expected to see the hottest weather of the week. In Vacaville, the high temperature is expected to reach 113 degree, according to the Solano NewsNet weather portal.

On Monday, the National Weather Service said Vacaville broke a high temperature record that was set just two years ago. In 2020, the high temperature reached 112 degrees; on Monday, the thermometer hit 115 degrees, the weather agency said.

Many of the region's cooling centers are expected to remain available for residents who need them. All Solano Public Library branches serve as cooling centers on days with extreme heat; the cooling centers are available during each branch's normal business hours. The Benicia Public Library, which is outside the county system, is also available as a cooling center.
