Weather Synopsis for Friday & Saturday
Don't forget the sunglasses and sunscreen. We're in for several days of beautiful springtime weather. Temperature inversions in the mountain valleys and passes could make it feel a bit chilly at some trailheads this morning. However, don't be fooled. A high-pressure ridge parked off the coast will bring us plenty of sunshine and warm temperatures. A few 5000ft sites could easily hit 50 F. Easterly wind will be a bit blustery along the Cascade Crest south of I-90 and on Mt Hood. This should keep these locations a notch cooler than areas further north and west.
Overnight, clear skies will allow lower elevations to cool slightly. Temperature inversions should develop across the region, but most middle and upper-elevation areas will stay well above freezing. Moderate winds continue in the same areas but slowly start to decrease.
Not much changes on Saturday. It could be cool near some trailheads to start the day, but it will warm up fast. As the ridge axis moves inland, wind speeds will significantly decrease. This means it will be sunny, hot, and generally calm.
