FAIRFIELD — A heat wave should begin making itself felt Saturday with temperatures in the 90s and rising to near or above triple digits in coming days.
“The best way to characterize it is it’s a late-season warm spell,” Cordelia Villages resident and Golden West Meteorology owner Mike Pechner said.
At this time of year, with summer over, the 100-degree mark is more elusive, Pechner said. But Solano County locations east of the Cordelia area could see temperatures above 100 degrees Sunday and Monday, he said.
The cool-off should begin Wednesday, when the National Weather Service predicts temperatures will drop back to 93 degrees in Fairfield. Thursday could see temperatures of about 87 degrees and Friday of 79 degrees.
“It’s a short hot spell,” Pechner said.
Locations in northern Solano County east of Travis Air Force Base should soon share in a weather record that Sacramento seems certain to set, Pechner said. That is the most days in September topping 90 degrees.
Friday marked the 24th day of reaching the 90-degree mark for Sacramento, tying the old mark. The coming heat wave should add the exclamation point to the new record.
“Indeed, it’s been a warm September, above normal once you get east of Travis,” Pechner said.
The predicted heat wave prompted the Bay Area Air Quality Management District to issue a Spare the Air alert for Saturday. It is advising residents to avoid driving when possible, avoid using gas-powered lawn mowers and leaf blowers and reduce household energy use to cut down on smog.
This marks the agency’s eighth Spare the Air alert for smog in 2012.
The National Weather Service on Friday issued an alert of its own, a special weather statement for the Sacramento region, including Solano County. The agency recommends people drink plenty of water, avoid strenuous activity during the heat of the day, never leave children unattended in a vehicle and wear lightweight and light-colored clothing.
Pechner said that, though temperatures will be high and humidity low, the winds should not be a major factor. This should temper the fire danger that comes with hot weather.
Local fire officials issued a warning of their own, advising people to use any powered equipment before 10 a.m. this weekend to minimize the chance of sparking a wildfire.
