Discussion:
A little bit of a break to start the workweek with some sun and warmer temperatures. But it is short lived. A stronger frontal system swings into western Washington on Tuesday.
Steady rain may move into Puget Sound during the morning commute. The widespread, steady rain should last into early afternoon before turning to off and on showers later in the day. It will breezy at times. It is a wet system for later in May. Rainfall in the lowlands should be around 1/2" and several inches in the mountains.
Showers will continue overnight and into Wednesday morning but then decrease during the day with gradual clearing as high pressure builds into western Washington. Thursday should see sunshine and warmer temperatures.
Friday will see another front move through, though not as wet or cool as Tuesday. It will be a damp start to the Memorial Day weekend, but it should improve during the weekend.
Cool air left behind Friday's front will still produce a few showers Saturday and Sunday but with gradually warming temperatures. High pressure will move through on Memorial Day for sunshine for the Holiday and highs in the mid 60s to near 70.
