Temperatures 10 to 20 degrees above historical averages warmed Northern California on Monday, and could break records on the coast Tuesday before gradually leveling off throughout the week.
Downtown Sacramento is predicted to hit 86 degrees Tuesday, the hottest Oct. 24 temperature since 1990 according to the National Weather Service. It would be 12 degrees above day’s historical average dating back to 1877, when the weather service first began collecting data.
Temperatures along the coast are forecast to be unseasonably high as well. Ukiah is expected to hit 95 degrees on Tuesday, threatening the 89-degree daily record set in 2003 and registering 22 degrees higher than previous Oct. 24s. In Santa Rosa, a predicted high of 94 is 18 degrees higher than the historical average and would be just one degree shy of the all-time record set in 1959, while Napa’s 90-degree heat would exceed the previous high by 4 degrees.
Though Sacramento highs are predicted to rest in the mid-80s after Tuesday, weather service meteorologist Idamis Del Valle said area temperatures would be 10 to 15 degrees above average through Friday before dropping slightly over the weekend. But fire risk is not severe, Del Valle said, as winds are expected to stay under 20 mph for most of the valley and coastline.
