Weekend Weather Forecast: Rain, Wind, and Cold Temperatures Ahead

The forecast indicates heavy rainfall diminishing by Friday evening, with strong southerly winds causing potential hazards. Showers will persist through the weekend, bringing snow to the mountains and cooler temperatures. Notably, an inversion effect may create patchy fog as Thanksgiving approaches, prompting continued care in travel and outdoor activities.

As the week progresses, significant rain is anticipated to diminish by Friday evening, following a pattern dictated by a warm front exerting its influence across the region. Winds will be notably strong, blowing from the south at speeds of 25 to 35 mph, with gusts reaching between 35 and 45 mph. These winds may lead to hazardous conditions, including fallen branches and power outages, making travel challenging.

The day’s weather is characterized by initial heavy rain, leading to the accumulation of water on roads and in parking areas. The rain will gradually lessen through the morning, giving way to intermittent heavy showers throughout the day and into the evening. Temperatures will fluctuate between the upper 40s to low 50s, while areas at the base of the Blue Mountain Foothills may see highs in the upper 50s to low 60s due to downslope winds. As temperatures drop tonight, the region will continue to experience showers, with nighttime lows ranging from the upper 30s to low 40s.

The weather pattern indicates that this low pressure system will drift along the Washington/Oregon coastline, stalling until Monday morning. Consequently, the weekend will involve sporadic showers, particularly in the mountainous areas where snow is expected in the Washington Cascades on Saturday and the Oregon Cascades and Blues on Sunday. Snow levels are forecasted to decline to approximately 4,000 feet by the conclusion of the weekend. As the upper low advances eastward, cool, dry air will infiltrate the region, resulting in colder temperatures and the potential for patchy fog in the mornings, especially into the Thanksgiving holiday and approaching December.

Expectations for the Tri-Cities indicate mostly cloudy skies with morning rain for Friday, transitioning into partly cloudy conditions with a chance of showers on subsequent days. Specifically, Friday will see a high of 50°F and a low of 39°F, while temperatures over the weekend will slightly vary between 35°F and 52°F. Yakima will experience similar weather, starting with mostly cloudy skies and morning rain on Friday, with a chance of showers prevailing throughout the weekend and temperatures ranging from 40°F to 49°F on average.

This detailed forecast underscores a transition from rainy to cooler, drier conditions as we near Thanksgiving.

The weather forecast discussed herein pertains to the expected precipitation and wind conditions in the region over the course of the upcoming weekend, notably emphasizing the significant rainfall occurring on Friday. The dynamics of this weather system, including the impact of a warm front and subsequent chilly, dry air moving in, elucidate the reasons behind the anticipated shift in conditions. Given the geographic context, the mention of mountain snowfall highlights the interplay between elevation and temperature. Understanding these patterns is essential for preparing for potential travel disruptions and gauging the overall climate in the lead-up to the holiday season.

In conclusion, the weather forecast predicts a significant transition from rainy conditions on Friday to cooler, drier weather as the weekend progresses, culminating in a chillier Thanksgiving week. The anticipated high winds and rain may disrupt travel and lead to localized hazards. Additionally, the weekend is expected to bring mountain snowfall and a gradual drop in high temperatures, suggesting a need for general preparedness as colder conditions settle in.
