The foul fog befuddling travelers and airlines for much of the past week has run its cycle.
"We might get a little more, but nothing like we've seen the past few days," said Misty Duncan of the National Weather Service in Medford.
The first predicted sprinkle accompanying a front on Wednesday failed to materialize, but a second front moving through today should bring some precipitation.
There might even be a chance of snow on the valley floor, Duncan said, with snow levels dropping to 1,300 feet.
"It all depends on how much moisture is coming with the front," she said.
The fronts have worked their way down the coast rather than moving inland, Duncan said.
"It's supposed to be turning inland when it gets to Southern California on Thursday," she said. "But we might get some weather from the tail end."
A break from the dense, freezing fog that's been plaguing Medford for the past few days will be welcomed.
More than 50 incoming and outbound flights were canceled as airlines did their best to cope.
Horizon Air said it canceled 25 flights this past week, including 21 since Sunday, affecting more than 1,700 passengers.
"It's frustrating for us and certainly for our customers," said Bobbie Egan of Alaska Air Group. "We've had to cancel flights when planes that overnight at the airport couldn't get in. After circling three times, they have to come back and we have to cancel the morning flights, as well."
When planes have mechanical issues, it's customary for airlines to reschedule passengers, when possible, with other airlines.
"The other airlines in Medford have the same issues and are not able to get in and out of Medford," Egan said. "I think Medford is unique this time of year. Residents are accustomed to the weather and are very understanding."
Rob Brewer, a spokesman for St. George, Utah-based SkyWest Airlines, said four round trips between Medford and Salt Lake City have been scrubbed since Sunday, and 18 round trips between the Rogue Valley and San Francisco or Denver were canceled.
