Seattle Weather Outlook: Cloudy Start Before System Arrives

Seattle residents can expect mostly cloudy conditions throughout Tuesday. The day will begin with some patchy morning fog, leading to a chilly start.

Despite the cloud cover, warmer air aloft will push temperatures slightly higher than previous days. Highs are forecast to reach the mid to upper 50s, aligning close to seasonal averages, though areas further north may remain cooler.

Midweek Weather Shift: Rain and Colder Air Incoming

The weather pattern is set to change significantly on Wednesday with the arrival of the next major weather system. This system will bring a return of rain, increased wind, and snow to the mountain passes.

An upper-level low pressure system is responsible for moving in the moisture. This feature will increase rain chances throughout Wednesday and usher in colder air masses for the region.

Mountain Snow Levels Drop Significantly

The incoming cold air will cause snow levels to drop considerably. Snow is expected to fall at elevations around 3,000 to 3,500 feet.

This means that several inches of snow accumulation are possible for the mountain passes on both Wednesday and Thursday. Lingering showers are possible on Thursday, primarily affecting the Cascades with snow.

Weekend Forecast: Warmer and Drier Conditions Return

Relief is on the way as high pressure begins to build into the area starting Friday. This shift promises warmer and drier weather conditions leading into the weekend.

Looking ahead to Easter weekend, conditions appear favorable. Sunshine and highs reaching into the 60s are looking likely for the holiday period.
