The Sacramento area recorded its first triple-digit temperatures of 2016 Tuesday, with downtown Sacramento topping out at 102 degrees.
Sacramento Executive and Sacramento International airports each reported a high of 101 degrees, said Idamis Del Valle, a meteorologist with the National Weather Service.
The torrid spring temperatures are due to a strong high-pressure system over Northern California and the dearth of a Delta breeze. The early season heat wave is expected to continue through Saturday. The average date for the first 100-degree day typically is about two weeks later, according to the National Weather Service.
In addition to warnings from health officials to keep hydrated and limit exposure to the sun, the Sacramento Metropolitan Air Quality Management District cautioned people with asthma to beware of high ozone levels. As of 3 p.m. Tuesday, the ozone level had reached the unhealthy stage in the Sloughhouse area and was reported unhealthy for sensitive groups in the Arden Arcade area.
Del Valle said a slight cooling is expected Sunday.
