Washington Weather Forecast: Lowland Rain, Mountain Snow Return

SEATTLE — After a brisk, mostly dry weekend, Western Washington will welcome back the rain, along with some mountain snow, as several weather systems move into the region in the coming days.

According to the latest forecasts, the recent bout of chilly and dry weather will give way to slightly warmer and wetter conditions as clouds return to Puget Sound.

Monday is poised to start fairly frigid, with temperatures in the high 20s to low 30s for most, ahead of the next weather system. Beginning Monday night, forecasters expect a new pattern will bring rain to the lowlands while snow levels drop as low as 1,500 feet.

Showers are likely to continue Tuesday, with some isolated thunderstorms near the coast and more snow possible in the Cascades. Wednesday should offer a brief break in the precipitation before a new system moves in, bringing more rain and high elevation snow, ahead of a stronger system possible Friday and Saturday.

Here is the 5-day outlook in the Seattle region:

Monday: 45°/42° (Clouds, then a chance of rain)
Tuesday: 47°/38° (Chance of rain)
Wednesday: 48°/40° (Mostly cloudy)
Thursday: 49°/43° (Rain likely)
Friday: 49°42° (Rain likely)

After a mid-week break, forecasters expect a new frontal system will approach, packed with breezy conditions, heavy rain and another round of mountain snow continuing into next weekend. Details on the amount of the late-week storm are still being refined and will be shared in the coming days.
