On Sunday, the region entered a third straight week of 90-plus temperatures, and National Weather Service officials say the next six days could produce a record.
Johnny Powell, NWS meteorologist, said downtown Sacramento on Sunday experienced its 15th day with a high of 90 degrees or above. The warm stretch started Sept. 2. That's just five days short of the record.
In 1899, Sacramento recorded 20 days of 90-plus degrees between Sept. 8 and 27.
Sacramento is forecast to continue the warmer daytime highs for perhaps the next six days. The low-90s are about 5 degrees above normal for this time of year.
"We're going for the record," Powell said. "If you're going to be warm, you might as well go for the record."
Usually by this time of year, he said, Sacramento residents are treated to a sprinkle or a cool daytime breeze. But he expects 90-plus degrees through Saturday.
Look for the relief at night, Powell said, as the shorter fall days bring a fast nighttime cool-down.
Those nighttime peak temperatures remain in the normal range in the high 50s to low 60s.
"It's flat-out nice at night," Powell said. "As soon as that sun goes down, it's like, 'Oh, wow.' "
