Monday Offers Seattle’s Best Outdoor Window
Monday looks like the week’s safest bet for outdoor plans, with dry weather, mostly sunny skies and north winds between 5 and 8 mph. Clouds return Monday night, but the low should only dip to around 56.
Tuesday remains mild at about 73 degrees, though the weather starts to turn after 5 p.m. A slight chance of rain arrives late Tuesday, rising to a 39% chance Tuesday night as clouds thicken across the city.
Midweek Rain Brings A Cooler Turn
Wednesday is the big forecast shift, with rain likely, mostly cloudy skies and a high near 68. Rain remains likely Wednesday night, while Thursday cools further to around 65 degrees with chances of rain, showers and possibly thunderstorms through the day.
The Seattle forecast discussion from the National Weather Service describes the midweek system as a strong, fall-like change for early September, with stronger winds possible around the region. No watches or warnings are currently listed for Seattle.
Friday stays cool with a high near 67 and a lingering chance of light rain, while Saturday rebounds slightly to around 69 under partly sunny skies. The setup is a notable change from the wetter weekend outlook in Hoodline’s earlier forecast, giving Seattle one more dry break before the rainier pattern settles in.
