A series of cold fronts brought widespread precipitation amounts of 1 to 2 inches across the west from Monday through Thursday night. Portions of the Star Valley and Yellowstone National Park received from 2 to over 3 inches of precipitation; the highest total of 3.07 inches was reported 5 miles north of Thayne in the Star Valley. A strong cold frontal passage also resulted in some high winds across the area on Wednesday with an automated station 15 miles southeast of Rock Springs reporting a gust to 81 mph Wednesday afternoon.
