A dangerous new heat wave is hitting California this holiday week. Not only will this one last the longest, but it’ll be the hottest in the northern part of the state since 2022. An Excessive Heat Warning begins tomorrow through Saturday with many places baking in temperatures 20-degree above average. Tomorrow, Santa Rosa is expected to top out at 105 degrees. Forecasters warn heat stroke is a real possibility especially as millions plan to be outside celebrating the Fourth of July.
