Unless it turns exceptionally wet in the next few months, the Inland Northwest is in store for an abnormally dry year, with a moderate drought forecast for much of Eastern Washington. The latest snowpack measurements show the Spokane basin at 74 percent of average, the Newman Lake basin at 58 percent and the Okanogan basin at 89 percent, the Washington Snow Survey Office said Thursday. The Pend Oreille basin, including parts of Idaho and Montana, is the exception, with its snowpack at 101 percent of average.
