Freeways and many arterial streets were bare and wet.Lingering ice and snow remained a problem east and toward the Columbia River Gorge — state Highway 14 closed for an avalanche, and Interstate 84 was closed overnight — and wet, slushy streets may present risk of hydroplaning.Still, the county seems to be warming back up. Weather equipment in Yacolt recorded a high temperature of 53 degrees. Pearson Field was 37 degrees. Washougal, 37 degrees.Pearson Field saw 1.3 inches of rainfall from 6 p.m. Tuesday to 6 p.m. Wednesday.Thursday in Vancouver, showers are likely before 4 p.m., and the day’s high temperature should be around 45 degrees. New rainfall between a tenth and quarter of an inch is possible. More rain is likely after 10 p.m., and Thursday night’s low will get down to about 36 degrees.Miles Higa, a meteorologist at the National Weather Service in Portland, said colder temperatures are expected later in the week, but they shouldn’t drop down to freezing in most areas.
