Could this be it at last? The National Weather Service says a major change in the weather is in store for Western Wyoming beginning Wednesday and continuing into the weekend. According to the Weather Service, a strong, moist westerly flow is expected to develop, breaking our dry weather pattern and bringing much-needed snow into the area. Forecasters say, with the warmer Pacific air accompanying the weather system, however, it is possible that the snow may mix with rain on the valley floor by Thursday afternoon. Otherwise, they see the precipitation coming in what they call “significant” amounts by the end of the week. Currently, snow water equivalents computed by the Natural Resources Conservation Service range from 57 to 75 percent of normal in the area’s river basins.
