FAIRFIELD — A chance of lightning striking dry brush continues, prompting the National Weather Service to issue a red-flag fire warning for parts of the region that could be in place through Wednesday evening.
But residents should get a break from the hot, humid weather that hit the area earlier this week, with high temperatures reaching 100 degrees. Instead, they should experience cooler, humid weather, with high temperatures in the low- to mid-80s.
The difference is an onshore breeze that kicked in Monday night, cooling temperatures Tuesday, said Mike Pechner, owner of Golden West Meteorology and a Cordelia Villages resident.
A low-pressure system that has caused the humid weather should leave the area Thursday.
“Then we’re just left with a nice, cool marine layer,” Pechner said. “We’re back to normal.”
The sultry weather has been caused by an upper-level low-pressure area, Pechner said. The circulation around the low is counterclockwise. The southern part of the low below Southern California picked up monsoon moisture.
“It’s something that’s not that unusual . . . of course, the fire concern is the major problem,” Pechner said.
The National Weather Service on Tuesday predicted the upper-level low would gradually move through Northern California. The agency reported lightning strikes in Napa County on Monday night. It dropped red flag warnings for part of the South Bay on Tuesday and expected the warning to be in place the longest in the North Bay.
Fairfield-Suisun City on Tuesday for the second day in a row had a striking sunrise because of the weather, with the orange disc of the sun visible amid a uniform bank of gray clouds.
