Several wildfires sparked overnight in the Oregon coast range and Cascade foothills. The National Weather service has issued a rare January Red Flag Warning for the region.

Trina Hartley is a meteorologist with the National Weather Service in Portland.  She says strong easterly winds encouraged the small blazes. A few are in the Cascades in southern Oregon But there were also several fires in the coast range.

Hartley: "On the coast in particular it's hard to get a fire started in July so to have these fire starts in January is extremely rare."

The South Willamette Valley has been blanketed in fog and clouds with an air stagnation advisory in place for more than a week.

At the Oregon Coast Monday, the sun was shining and the temperature was in the mid-50s. Meanwhile Eugene-Springfield has been encased in fog and clouds with temperatures barely edging above 40.

Freezing rain is expected in the early afternoon Thursday, but normal temperatures will begin creeping up this weekend.

The South Willamette Valley should be experiencing warmer weather as early as Friday, with temperatures predicted to reach the mid 40s in the afternoon. Hydrologist Andy Bryant of the National Weather Service says despite some Friday night cold, the weekend should be warmer.
