Weather Synopsis for Sunday & Monday
Well, things are shaping up to be a downright gorgeous day in the mountains Sunday. Most areas this morning are seeing sunny skies with a few low clouds in the mountain valleys and passes. This trend should continue for most locations throughout the day. Look for mostly sunny skies, light winds, and warming temperatures. Clouds will creep into the region this afternoon ahead of the next weather system in areas north of I90. Don't forget your sunscreen if you're heading out into the hills today.
Our sunny weather will be short-lived as the first in a series of storms approaches the area Monday night. Clouds will increase and thicken as showers eventually spread from north to south. This system hangs up on the Cascade crest with only a few isolated sprinkles making it further east. Initially, cold air keeps all the precipitation as snow. That changes as the bulk of the storm arrives Monday morning and snow levels begin to march upward. This first system doesn't bring much in the way of moisture. Its biggest impacts come from warm temperatures and increasing winds. Several locations should see strong winds by Monday afternoon. There may be a brief break in the action late in the day, but the second storm follows hot on the heels of the first maintaining a warm, wet, and wind pattern.
