SEATTLE, Wash. — Below-normal temperatures are expected to dominate across Washington from Valentine’s Day through Feb. 20, reinforcing a persistent winter pattern that will bring continued chances for rain and snow statewide.
In western Washington, including Seattle, daytime highs are forecast to remain mostly in the upper 30s to lower 40s, several degrees below seasonal averages. Overnight lows will frequently dip into the low to mid-30s, allowing for occasional rain-snow mixes, particularly during overnight and early morning hours.
The Cascade foothills and mountain passes will see more consistent snowfall during this period, with light to moderate accumulations possible as weak disturbances move through the region. Travel through Snoqualmie Pass and Stevens Pass may be impacted at times, especially during periods of heavier snow or reduced visibility.
Eastern Washington will remain colder overall, with highs largely confined to the 20s and lower 30s and nighttime lows dropping into the teens. Snow chances will be more persistent east of the Cascades, where colder air will support mostly snow rather than mixed precipitation.
Winds are expected to remain generally light, though occasional breezy conditions could enhance the cold feel, particularly in exposed areas. Cloud cover will limit daytime warming, reinforcing the extended stretch of below-average temperatures.
Looking ahead to early next week, no significant warmup is expected. Forecast guidance suggests the colder-than-normal pattern will persist, keeping winter firmly in place across Washington. Residents should continue preparing for winter driving conditions and monitor local forecasts for updates as the Valentine’s Day weekend approaches.
