Weather service officials said the increased temperatures may catch some people by surprise since it has been so cool recently.

Moderate to locally high risks for heat impacts will develop inland and low to locally moderate risks will develop along the coast.

According to the weather service, temperatures in the hills and mountains will still be mild overnight Thursday and Friday. Temperatures are expected cool gradually on Saturday and then even more on Sunday.

Wildfire concerns will be low because of generally light winds, weather service officials said.
