Forecast models from KOIN indicate that a wet and windy pattern building over Portland on Saturday is also expected to extend north into Southwest Washington, bringing intermittent rain and breezy conditions to communities along the I‑5 corridor, including Longview and Kelso. According to the station’s meteorologists, scattered showers were expected to begin moving into the region early Saturday, with temperatures remaining cooler than seasonal norms.

The National Weather Service’s most recent regional outlook for Southwest Washington on February 21, 2026, also called for light to moderate rainfall throughout the day, accompanied by periods of gusty wind in exposed areas. While no hazardous weather advisories were in effect for Cowlitz County as of Saturday morning, forecasters noted that travel conditions could be temporarily slowed by reduced visibility or brief heavier showers.

Local impacts are likely to be minor but noticeable. Residents may see slick roadways, unsettled cloud cover, and colder-feeling conditions due to wind chill at times. Public works officials in Cowlitz County have not issued any special alerts, but standard seasonal precautions remain advisable — including allowing extra travel time during showers and securing lightweight outdoor items ahead of breezier periods.

Forecasters expect the wet pattern to continue intermittently through the weekend before moderating early next week.

Why this matters

Late‑winter storms like this one rarely produce major hazards in Cowlitz County, but they influence transportation, outdoor labor, and energy usage. Monitoring these shifts helps residents and local agencies stay ahead of short-lived disruptions that can affect safety and mobility across the region.
