The forecast for Star Valley the past couple of days has called for mostly sunny. Anyone in the valley knows that there has been very little in the way of sunshine on Thursday and so far today. As with most of the weather that effects Star Valley, the mountains play a big role. In this case even though Idaho Falls and Pocatello have been enjoying lots of sunshine, the lift from the Caribou and Salt Ranges has continually developed cloudiness. To see this process in action go to the Web Camera page and build a several hour loop off the first cam looking out over the valley. The processes that are maintaining the cloud cover over the valley are quite evident. This can also be seen on the Forecast page and the visible loop over the area.
