Weather Synopsis
Hello, springtime! Things are shaping up for a beautiful day across the mountains with mostly sunny skies, warming temperatures, and generally light winds. However, it will be a bit chilly at the trailheads this morning, with overnight lows in the teens and 20s F.
A weak frontal system is brushing the Olympics and North Cascades, bringing cloudy skies, a few light showers, and moderate winds to those areas. This shouldn't linger too long into the morning. Elsewhere, a few low clouds and patchy fog can be found. After the cold start, clearing skies and ample sunshine help temperatures quickly rise. Daytime warming will be most pronounced further east and south in the forecast region, where you could see 5000 ft temperature reach near or above 40F.
Mostly clear skies Sunday evening should allow for temperatures to cool, forming inversions in the mountain valleys and passes. With light to calm winds, low clouds and patchy fog could develop, especially near rivers and lakes. The jet stream starts to turn slightly SW overnight and lift northward. This begins to draw in warmer air to the southern forecast zones and allows freezing levels to stay high even as pockets of cold air form in the valleys.
Monday looks like a transition day ahead of our next weather system. Some locations could start the day sunny, but high clouds gradually thicken and lower. SW winds usher in warmer air with freezing levels rising significantly by the afternoon. Precipitation won't arrive until overnight, but the mild temperatures certainly hint at the rain to come.
