Weather Synopsis for Tuesday night through Thursday
The Pacific Northwest remains dry Tuesday night, sitting between a broad upper trough and an approaching weather system. This will bring a mostly clear night with light winds. The approaching system will draw colder air southward along the E slopes of the Cascades and also through the Fraser River Valley overnight. The cold air in places sets the stage for a snow (rather than rain) event once precipitation arrives on Wednesday.
A warm front lifts northward on Wednesday as the low-pressure tracks toward the mouth of the Columbia River. It spreads increasing snowfall to the Mt Hood area after 8 AM, with precipitation moving into the southern Washington Cascades in the afternoon. Increasing light to moderate ESE winds peaking late Wednesday will allow for some upslope snowfall along the E slopes of the Cascades.
The low-pressure center likely lingers near the Washington Coast Wednesday night and Thursday, with snowfall continuing to focus on the southern half of the forecast region.
