Very little change in the forecast. Showers, clouds, and cool temperatures are the trend this week as a large upper level trough of low pressure sits over the northern Rockies. One storm system is northeast of Montana, in Canada, but will continue to spin energy into the region and bring valley rain and mountain snow showers through Thursday. A stronger storm system is currently just off the coast of Washington and Oregon. It will move inland and begin impacting the area with more rain and mountain snow, especially late Friday through Sunday. Significant precipitation is possible and this will impact the holiday weekend. Accumulating snow is likely in the mountains with a mix of rain and snow even in some valley locations. Outside of the areas of precipitation, skies will be partly to mostly cloudy through Sunday. Temperatures will remain well below normal for the latter half of May.
