The National Weather Service in Seattle has provided a detailed forecast for the coming week, indicating a series of rainy days ahead for the region. As reported early this morning, current conditions show a clear sky with temperatures lingering around 45°F and humidity high at 93%. The calm before the storm, it seems, with the barometer reading at 30.3 inches (1026.08 mb) and dewpoint at a cool 43°F according to NWS Seattle.
Looking ahead, Seattle residents should prepare for a turn in weather patterns with mostly cloudy skies and a high near 55°F expected today. A light north wind of around 6 mph will be present. While creeping clouds are forecasted to bring a low around 46 tonight, a calm wind turning south around 6 mph after midnight could make for a variable experience in localized areas.
Friday's outlook is wetter, with rain anticipated mainly after 11am. With the south wind maintaining a pace of about 7 mph, temperatures will hover near 55°F. The NWS Seattle estimates an 80% chance of precipitation with new rainfall amounts measuring between a tenth and a quarter of an inch. Then, Friday night, predictably, rain is certain with a 100% chance as totals may increase to the range of three-quarters to one inch.
Continuing through the weekend, Saturday persistently brings rain with a 100% chance of precipitation and new quantities anticipated between a quarter and a half of an inch, complemented by a modest south-southwest breeze around 10 mph. While rain is likely before 11pm, temperatures will descend to a low of around 45°F at night. Even though the chance reduces to 70%, new precipitation may not exceed a tenth of an inch.
The following days offer a brief reprieve on Sunday with a 30% chance of rain before 11am and partly sunny skies, a welcome change for those yearning for a glimpse of the elusive autumn sun. However, the nighttime will retreat back into mostly cloudy conditions with a low around 45°F.
The pattern of unsettled weather appears set to continue into next week. Chances of rain make a comeback Monday after 11am, with mostly cloudy skies and a high near 54°F. Rain becomes likely again Monday night, setting the stage for a damp week ahead. Tuesday and Wednesday are expected to follow suit with likely rain and high temperatures cresting near 57°F and 58°F, respectively, enveloping the city in a persistently moist embrace.
