Seattle weather: Cooling Memorial Day after sunny weekend

Patchy fog and widespread clouds created a murky start to Saturday across Western Washington, although some sunbreaks were expected to develop later in the afternoon as higher-level clouds gradually gave way to filtered sunshine. 

Afternoon highs ended up running about five degrees cooler in Seattle compared to Friday as a weaker area of high pressure remained in place over the region. Even with the slightly cooler temperatures and stubborn cloud cover early in the day, conditions were still expected to stay primarily dry for most of Saturday.

More sunshine will return Sunday morning before thicker clouds increase later Sunday evening ahead of the next incoming weather system. Temperatures will climb into the low 70s Sunday afternoon before a noticeable cooling trend arrives for Memorial Day Monday.

Seattle weather turns more unsettled for Memorial Day with showers, breezy conditions, and a slight chance of thunderstorms.

Memorial Day will bring a return to wetter and more unsettled conditions across western Washington, with periods of rain, scattered showers, mostly cloudy skies, breezy weather, and even the possibility of a few isolated thunderstorms. High temperatures Monday will cool back into the low 60s as the trough of low pressure moves overhead. There might be higher surf along the far coast as well.

By Friday, skies are expected to turn cloudier again with slightly cooler temperatures and a slight chance for a shower.
