The National Weather Service expects the Mid-Columbia to see a wintry mix of rain and snow this week, with high temperatures topping out at 41 degrees.
The rain and snow showers were to move in overnight Monday, then possibly change to freezing rain and patchy fog until 10 a.m. Tuesday, the weather service said.
However, the weather service also predicted little or no ice and snow accumulation for the Tri-Cities.
The high for Tuesday and Wednesday will be 36 degrees, with another chance of snow at 4 a.m. Wednesday before changing to possible rain showers throughout the day into the night.
The weather service also said an air stagnation advisory remains in effect until 10 a.m. Dec. 19. That means pollutants might be trapped near the ground, which can affect people with respiratory conditions.
