Patchy fog and freezing fog will develop tonight into tomorrow morning for Yakima and Tri-Cities overnight lows in the 20’s. The fog should move out late Saturday morning with sunshine for the rest of the day high temps in the upper 30’s to low 40’s. Increasing clouds Sunday morning as the next system moves onshore.  Light snow or rain/snow mix will likely start late afternoon/evening and then transitions to snow Sunday night.  This system is still several days out, but light snow could be possible...
