Weather Forecast: Rain and Wind Advisory Through Friday Evening

The weather forecast predicts heavy rainfall and strong winds across the region on Friday, with temperatures varying from the upper 40s to low 60s. Conditions will continue with showers into the weekend, leading to cooler temperatures as colder air moves in from Canada. Significant snowfall is expected in the Cascades, with high and low temperatures gradually decreasing as Thanksgiving approaches.

On Friday evening, a significant rainfall is forecasted across the region, accompanied by a Wind Advisory affecting the base of the Northern Foothills of the Blue Mountains, expected to remain in effect until 3 p.m. The winds are projected to blow from the south at speeds of 25 to 35 miles per hour, with gusts reaching 35 to 45 miles per hour, potentially resulting in fallen branches, power disruptions, and hazardous travel conditions.

The day will begin with considerable rain leading to standing water on roadways and parking lots. The precipitation is expected to decrease during the mid-morning, followed by sporadic heavy showers throughout the day and evening. Temperatures will range from the upper 40s to low 50s, although the downslope winds will ensure the foothills experience temperatures in the upper 50s to low 60s. As nighttime approaches, showers will continue with lows dropping to the upper 30s and low 40s.

A low-pressure system is anticipated to maintain its trajectory, influenced by an atmospheric river, and will stall along the Washington-Oregon coastline until Monday morning. This disturbance will impose light showers over the weekend, with snowfall expected in the Washington Cascades on Saturday and in the Oregon Cascades and Blues on Sunday, as snow levels fall to roughly 4,000 feet.

As the weekend concludes, a shift toward cooler and drier conditions is predicted as the center of the upper low moves eastward, ushering cold air from the north. High pressure from Canada is expected to settle into the region, resulting in daytime highs dropping into the upper 40s and mid-40s, whereas nighttime lows may approach or dip below freezing throughout the upcoming week. An atmospheric inversion may develop at mid-levels, maintaining relatively stable temperatures through Thanksgiving, with a possibility of morning fog from the weekend into early December.

In summary, the weather forecast for the Tri-Cities includes cloudy conditions with rain on Friday, leading to a mixture of clouds and slight chances of showers over the weekend, and a transition to cooler temperatures next week. Yakima will experience a similar pattern, with a predominance of cloud cover and potential fog conditions emerging.
