Dense fog that made for difficult driving conditions Thursday morning is expected to be back again Friday morning.
But by Friday afternoon, fog is expected to clear. Through the weekend, skies over Fresno should range from partly cloudy to clear and sunny.
There is a slight chance of rain in the high Sierra starting Saturday night, said meteorologist Christine Riley with the National Weather Service in Hanford. On Thursday night, it was unclear whether any of those possible showers might reach the central San Joaquin Valley.
But Fresno temperatures should drop nearly 10 degrees by Sunday, Riley said, with a high around 60 degrees.
Riley said Valley fog Thursday morning was denser than earlier in the week. A driver died early Thursday when his pickup hit a signal light pole in heavy fog, Visalia police said.
Donald Erwin McGinnis, 57, whose hometown was not provided by police, collided with the pole at the southwest corner of Dinuba Boulevard and Houston Avenue about 4 a.m., police said. He was driving a 2007 Dodge truck.
He was taken to a local hospital but died from his injuries. There were no passengers, and drugs or alcohol do not appear to be a factor, police said.
Elsewhere in the Valley, several traffic collisions were reported with reduced visibility because of fog.
An accident involving two vehicles south of Kingsburg resulted in minor injuries near Road 8 at Avenue 388. Another crash sent at least one car into a vineyard at Jameson Avenue and Kamm Avenue in Fresno County. Near Selma, a single vehicle overturned, leaving one person injured.
People should try to avoid driving in the fog whenever possible, California Highway Patrol officer Marc McWilliams said. He suggested that motorists postpone commutes if they can.
“If you do have to drive, keep your low-beam headlights on,” McWilliams said. He also advised motorists to increase the following distance behind other vehicles and to slow down.
