SAN FRANCISCO (KRON) – The National Weather Service is reporting a developing high pressure in the four corners of the western United States that could bring extreme heat to some parts of the Bay Area.

While the Pacific Ocean might keep the coast cool, inland valleys could see triple digits by the end of the week.

This excessive heat comes as drought conditions continue to worsen across the state.

Exceptional drought, the most severe designation, was expanded to areas in Sonoma and Marin Counties on Thursday.

The drought emergency declared in California on May 10, 2021, by Gov. Gavin Newsom remains unchanged.
