The Sacagawea Heritage Trail fades into dense fog Thursday morning walkers stroll past the North Fruitland Street access in downtown Kennewick.
The chilly blanket rolled in at 9 a.m. and seemed thickest near the rivers. Morning patches of fog are expected to give way to sunny skies and warming temperatures over the next few days.
Highs should be in the mid to upper 60s through Tuesday, according to the National Weather Service.
