A temperature inversion is locked in place over the Treasure Valley, keeping cold air in place at lower elevations. Above about 6000 feet the air begins to warm a bit. But a Pacific storm is headed our way tonight and will spread clouds and snow showers into southwest Idaho by Friday morning. The storm is quite weak and low in moisture, so we don't expect much more than some flurries or light snow showers.
Behind the storm, the inversion settles back in through the middle of next week. Cloudy on Saturday, partly cloudy Sunday through about Wednesday, with some patchy fog/low clouds/haze. Temperatures will be in the upper 20's to low 30's each day, with lows in the low 20's.
