Significant rain is forecasted, tapering off by Friday evening, with a Wind Advisory in effect. Rain will lead to standing water on roads initially, giving way to intermittent showers. Temperatures will remain cool, with highs in the 40s and 50s and lows dipping towards freezing by early next week. A low-pressure system will continue to influence the weather through the weekend, with the potential for mountain snow and colder air settling in for Thanksgiving.
In the forthcoming days, residents can expect significant rainfall slowing down by Friday evening, accompanied by a Wind Advisory for the base of the Northern Foothills of the Blue Mountains, which will remain in effect until 3 p.m. Friday will commence with substantial rain across the region, potentially resulting in standing water on roads and parking lots. The warm front will loosen its grip by mid-morning, allowing intermittent heavy showers to persist throughout the day and into the evening, with temperatures ranging from the upper 40s to the low 50s. However, the foothills of the Blue Mountains could see temperatures rise into the upper 50s and low 60s due to downslope winds. As winds diminish tonight, scattered showers will continue overnight, accompanied by lows in the upper 30s and low 40s.
The low-pressure system is set to diverge from the atmospheric river which facilitates its development, stalling along the Washington/Oregon coastline until Monday morning. Consequently, sporadic showers are anticipated to linger throughout the weekend, while mountain snow is expected in the Washington Cascades on Saturday and in the Oregon Cascades and Blue Mountains on Sunday. Snow levels are projected to descend to approximately 4,000 feet by the weekend’s conclusion. Transitioning into the beginning of next week, the region will experience a shift towards cooler, drier air as the upper low moves east, bringing with it cold Canadian air. High temperatures are anticipated to decline into the upper 40s and mid 40s, with night-time lows approaching freezing, potentially dipping below it as the week progresses. An inversion phenomenon may materialize in the mid-atmosphere, stabilizing temperatures as we approach the Thanksgiving holiday, with an increased likelihood of morning fog by the subsequent weekend and into early December.
