.Forecast Summary...A Pacific storm will bring gusty winds and showers today. Showers will start this afternoon and last through the evening. The snow level will be above 5500 feet so snow will be confined to the mess and higher mountains. This system will be to our east by tomorrow morning. The next and colder storm will move through our area tomorrow night into Wednesday morning. It will be cold enough to produce snow showers even for the lower elevations including Mercury. Accumulations for the lower elevations will be minor. A third and even colder system will pass through on Thursday. It will not have much moisture associated with it so only some light snow showers are currently expected with no accumulations for the lower elevations. Friday through Sunday will be uneventful with high pressure over the region.
