Spokane, Washington – A marginal winter weather pattern may influence Eastern Washington late next week, with limited chances for rain and snow holding near 40 percent. While colder air is expected to remain in place, moisture appears limited, reducing the likelihood of widespread or high-impact precipitation.
According to the National Weather Service and the Climate Prediction Center, Eastern Washington sits on the drier side of a broader Pacific Northwest pattern during the 8–14 day period. While temperatures are expected to remain near or below seasonal averages, precipitation signals remain modest, favoring dry conditions with only occasional chances for light rain or snow.
Across Spokane, Pullman, Moses Lake, and the Columbia Basin, any precipitation that does occur is likely to be light and intermittent. Daytime periods may remain dry, with the best chance for brief snow showers coming overnight or during early morning hours when colder air is more firmly established.
Snow chances increase slightly across higher elevations, including the Blue Mountains and areas near the Idaho border. Even there, snowfall appears limited, with no strong signals for significant accumulation at this time. Any snow that falls is expected to be light and patchy.
Because precipitation chances remain limited, widespread travel disruptions are not anticipated. However, cold temperatures could allow icy patches to develop where light snow or residual moisture occurs, especially on bridges and shaded roadways along I-90, U.S. Route 2, and rural highways.
Residents are encouraged to monitor updated outlooks, but winter weather impacts across Eastern Washington are expected to remain limited. Confidence will improve as the timeframe approaches, and any advisories would be issued if colder or wetter trends strengthen later in the period.
