A cold front will cross Western Wyoming this Thursday evening bringing an end to the unusual string of warm days for Star Valley. The strong cold upper trough moving eastward with the front is responsible for the change.

Along with the 500mb analysis is the corresponding radar image showing the more widespread precipitation along with cold front. While scattered showers and thundershowers have occurred across Star Valley Thursday afternoon, when the front passes more general showers will occur with a rapidly lowering snow level. Very gusty winds have been reported with the Star Valley Ranch observation hitting 56 mph at 1:45pm with a passing thundershower.
By morning the snow level will have lowered to the valley floor but any significant accumulation should be confined to the higher elevations with several inches possible above 7500 feet.
The Riverton WFO has provided a short video discussion covering the expected weather for Western Wyoming through the first of next week. It can be viewed here.
