Rain, snow forecast mid-week in Washington

After one more dry day, a change is expected in the region’s weather this week. Spokane’s chances for snow begin during the overnight hours Tuesday, with a 70 percent chance of precipitation, according to the National Weather Service. A wintry mix remains a possibility throughout the week, with rain or snow forecasted Wednesday and Thursday. Daily snowfall totals in Spokane are not expected to exceed an inch, forecasters say. The precipitation will churn up stagnant air that has sat over the region for the past several days. An advisory is scheduled to expire Tuesday morning. While trace amounts of snow have been measured at Spokane International Airport in recent days, Spokane has not experienced a snowfall greater than one inch since Jan. 7, according to National Weather Service observations. In January, Spokane should see between 11 inches and one foot of snow, based on seasonal averages. This year, just three inches have fallen. The weekend should be mostly cloudy, with a 20 percent chance of snow Saturday. High temperatures this week will dwell in the lower 30s, with overnight lows in the upper 20s.
