Mountain Weather Forecast

Weather Synopsis

If you're enjoying the warm sunny weather, you're in luck! We have more on tap for Sunday. A high pressure ridge has taken up residence over the Pacific Northwest and will continue to bring us mostly clear skies, generally light winds, and warm temperatures through the rest of the weekend and into the start of the work week. 

High thin clouds persist Saturday night. While they may slightly curtail overnight cooling, it shouldn't be enough to fully stop it. So, low temperatures will dip, but likely stay above freezing. Weak inversions could form in some of the mountain valleys and passes, with the coldest (but likely still above freezing) temperatures occurring at these lower elevations. 

If you're off to hunt Easter Eggs in the snow on Sunday, it looks like yet another gorgeous spring day! Once again, high thin clouds may keep it from being fully bluebird, but the sunshine and warm temperatures will certainly make themselves known. Five thousand ft temperatures should easily reach into the 50s for nearly the entire forecast region. Some sites may even flirt with 60 F by the afternoon. Look for light to moderate SE winds to become more noticeable in places near the Cascade crest from I-90 southward to Mt Hood. These offshore (east) winds should bring the warmest temperatures to locations west of the spine of the range, like Mt Saint Helens, Mt Rainier, and Mt Baker. 

A low pressure system passing well to our north in British Columbia will cause the high pressure ridge to bend but not break Sunday night and into Monday. The biggest changes to the weather will come from increasing upper elevation winds and a better chance for partly cloudy skies. Precipitation from this storm should generally stay north of the border, and any sprinkles would likely hold off until Monday night or Tuesday.
