Southwest flow ahead of a large storm currently spinning off the Pacific Northwest coast will carry some tropical and subtropical moisture through the Steamboat Springs area later today into Tuesday. Relatively warm showers should start later this evening and peak during the overnight hours, with the snow level near the top of Mt. Werner.
Light showers may persist in the cool northwest flow behind the small storm on Tuesday, but should end later in the day as the atmosphere dries and stabilizes under a building ridge.
Warm and sunny weather should return for Wednesday and Thursday before additional energy dropping southward from the Aleutians forces the Pacific Northwest storm to elongate and move eastward. The storm is forecast to split, with the the tail end of the northern branch bringing a dry cool front through the area on Friday as it moves across Montana.
Meanwhile, the southern end of the split makes landfall around central California on Friday and mixes with a topical system moving northward from Baja. Current model forecasts have the ridge rebuilding behind Friday’s cool front, so it is unclear how much of this energy will make it to the Steamboat Springs area by Saturday, but another round of relatively warm showers are possible.
Drier weather should return for the end of the weekend for a short time before more Pacific energy moves what was once the Aleutian storm eastward. Once again, the threat of showers will increase by late in the weekend or early in the next work week as that storm crosses the California coast and moist southwest flow increases.
