Another round of winter is expected to hit the area Thursday afternoon into Friday morning. Roadways will be slick in spots, with rain and snow likely between 4 pm and 10 pm. Maybe you can get whatever needs to be accomplished before then. That's my plan.
According to the National Weather Service in Pendleton, OR, the Tri-Cities area will receive snow mixing with freezing likely between 10 pm Thursday and 1 am Friday. Little or no accumulation is expected. Although, other agencies reporting up to an inch accumulation is possible. Friday's high will be in the low 40's, so, the snow won't stay.
As far as driving in snow and ice, slow down. Many people are cited for driving too fast for conditions. Leave extra room between vehicles, alow down when approaching intersections, bridges, off-ramps, and overpasses.
