Weather Forecast: Rain, Wind, and Cooling Trends Through Thanksgiving

The weather forecast indicates that the region will experience significant rainfall followed by scattered showers into the weekend. Wind advisories are in effect, with expected gusts causing potential hazards. A low-pressure system will stall along the coastline, leading to mountain snow, while cooling temperatures hint at a dry and cold transition into Thanksgiving week.

On Friday, significant rainfall is anticipated across the region, leading to potential standing water on roadways and in parking lots. The rain is expected to taper off by mid-morning, followed by scattered heavy showers throughout the day and into the evening. With high temperatures reaching the upper 40s to low 50s, the base of the Blue Mountain Foothills may experience even higher temperatures due to downslope winds. However, winds will exhibit strength ranging from 25 to 35 MPH, with gusts potentially reaching 45 MPH, posing risks such as fallen branches and travel hazards. As night falls, temperatures will drop into the upper 30s to low 40s, accompanied by continued showers.

This weather system is a low-pressure area that will travel a diffluent path from the atmospheric river that contributes to its development. It is expected to stall along the Washington/Oregon coastline until Monday, maintaining the likelihood of stray showers throughout the weekend. Notably, mountain snow is forecasted for the Washington Cascades on Saturday, while the Oregon Cascades and the Blues will see snowfall on Sunday, with snow levels dropping to around 4,000 feet.

By the end of the weekend, cool, dry air will settle as the core of the upper low transitions eastward, allowing cold air to move southward. This will initiate high-pressure development in the region, potentially resulting in high temperatures in the upper 40s and mid-40s, as well as nighttime lows nearing or below freezing throughout the week. A mid-level atmospheric inversion may emerge, maintaining consistent temperatures through Thanksgiving, with the possibility of encountering patchy fog during the mornings as the month progresses toward December.

A low-pressure system forming along the Washington/Oregon coastline contributes to ongoing rain and potential snowfall in the nearby mountain ranges. The forecast highlights wind advisories, temperature fluctuations, and the likelihood of fog that may affect visibility and travel.

In summary, Friday will begin with considerable rainfall and wind advisories, transitioning into a weekend with scattered showers and potential snowfall in the mountains. While temperatures may dip significantly, resulting in cold conditions, the forecast indicates a gradual movement towards drier weather by the end of the weekend. Residents should remain aware of possible travel hazards due to wind and standing water on roads, as well as prepare for colder temperatures as the season progresses.
