Redding Record Searchlight The National Weather Service warns North State residents will see temperatures so high this weekend, they're considered dangerous to people's and animals' health. The NWS issued excessive heat warnings for Northern California's interior, in effect Friday afternoon through Monday night. Temperatures over the weekend are forecast to go as high as 116 degrees in the Sacramento Valley, and well above 100 degrees in the foothills. Mountain temperatures could reach 105 degrees. Hottest temperatures — arriving Saturday and Sunday — could shatter daily record highs, said NWS meteorologist Scott Rowe in Sacramento. Redding could reach 116 degrees both days. That would beat previous records set on July 10, 2002 (115 degrees) and July 11, 1999 (114 degrees), Rowe said.
