Seattle, Washington – The Pacific Northwest is entering a noticeable pattern shift as above-normal temperatures take hold during the February 7–20 period, bringing a milder, more spring-like feel to much of Washington and Oregon after weeks of winter variability.
According to the National Weather Service Climate Prediction Center, temperatures across the Pacific Northwest are expected to trend above seasonal averages through mid-February, especially west of the Cascades. Daytime highs are expected to moderate across the I-5 corridor from Seattle and Tacoma south through Portland and Eugene, while overnight lows remain mild enough to limit widespread frost concerns.
While temperatures turn warmer, the pattern will remain active. Pacific systems are expected to continue moving inland, bringing periodic chances for rain across western Washington and Oregon. These systems are likely to arrive in waves rather than as prolonged storms, but heavier bursts of rain could lead to slick roads, reduced visibility, and localized ponding during commute hours along Interstate 5, Highway 99, and major urban arterials.
In the Cascades, warmer air may push snow levels higher during precipitation events, allowing rain at lower passes while snow continues at higher elevations. This could lead to changing travel conditions along mountain routes such as Snoqualmie Pass, Stevens Pass, and Santiam Pass during active periods.
The milder setup offers a temporary break from colder winter conditions and hints at early spring across lowland areas. Transportation agencies advise drivers to remain alert during rain events, particularly in urban corridors and areas prone to poor drainage.
Forecasters stress that while the pattern leans warmer, winter is not over. Additional shifts remain possible later in the month. Residents are encouraged to monitor updates as precipitation timing becomes clearer and as any advisories are issued during the February 7–20 window.
