Air stagnation advisory extended

The air stagnation advisory issued by the National Weather Service almost two weeks ago has been extended through noon Friday. The weather will finally change from fog and stagnant air on Saturday as snow comes into the area followed by an arctic blast. Temperatures will stay below freezing today for the Inland Northwest with highs and lows in the 20s, according to the weather service. Thursday morning will bring some patchy fog with possible freezing fog, and a high near 30. The low will be 21 in Spokane. On Friday, the haze will start to clear in the morning, but clouds will move in for a slight chance of snow that is forecast for the evening, according to the weather service. More snow is expected Saturday. Forecasters are predicting 1 to 2 inches, but it’s still early, officials said. By Sunday night, the area could see single digit temperatures.
