Seattle, WA – Gray skies are gathering over Puget Sound as Seattle prepares for several rounds of November rain. Temperatures will reach 61 degrees Thursday, but conditions turn wetter Friday before rain chances climb to 100% Saturday night.
According to the National Weather Service in Seattle, rain becomes increasingly likely Friday, with an 80% precipitation chance during the day.
The developing pattern could affect travel, outdoor activities and weekend plans across Seattle, King County and surrounding Puget Sound communities.
From 61 Degrees to Three Days of Rain Thursday offers a relatively mild break before the wetter weather arrives.
Seattle should reach approximately 61 degrees under mostly cloudy skies, with light south southeast winds.
Rain chances increase to 30% late Thursday night, mainly after 4 a.m. Friday.
By Friday morning, rain becomes more widespread.
Forecasters expect an 80% chance of precipitation Friday, mainly before 2 p.m., with temperatures reaching approximately 59 degrees.
New rainfall amounts of less than one tenth of an inch are possible during the day.
Although totals appear relatively modest in the local outlook, repeated periods of rain could leave roads consistently wet.
Drivers using Interstate 5, Interstate 90 and other major Seattle area routes should prepare for reduced visibility and slick pavement during heavier showers.
Saturday Night Brings 100% Rain Chance Saturday provides little relief from the unsettled pattern.
Rain remains likely, especially after 4 p.m., with a 60% precipitation chance and temperatures near 57 degrees.
By Saturday night, the probability of precipitation reaches 100%.
That is the highest rain probability shown in the supplied five day outlook.
A 100% chance indicates precipitation is expected at the forecast location, not that heavy rainfall or flooding is guaranteed.
Sunday continues the wet stretch, with rain expected and afternoon temperatures near 55 degrees.
Residents attending sporting events, traveling around Puget Sound or planning outdoor activities should keep waterproof clothing nearby.
Pacific Storm Pattern Keeps Northwest Unsettled The broader weather pattern also deserves attention.
The NOAA Weather Prediction Center expects a Pacific storm system to bring heavy precipitation and strong winds to portions of the Pacific Northwest beginning Friday.
However, the Seattle point forecast does not indicate damaging winds or a specific flooding threat.
For now, repeated rainfall and wet travel conditions remain the primary local concerns.
Temperatures gradually cool through the weekend, dropping from Thursday's 61 degree high to approximately 54 degrees Monday.
That seven degree decline reinforces the region's increasingly damp November weather pattern.
