MJP –
A period of dry and calm weather is expected through Saturday afternoon as high pressure moves over the region, bringing quiet conditions to the Pacific Northwest. However, a weak weather system will arrive over the weekend, bringing a chance of light rain and mountain snow.
The National Weather Service forecasts that unsettled weather will return next week, with snow in the mountains and rain in the lowlands. Mountain passes may experience moderate to heavy snow, potentially impacting travel.
Tonight through Friday morning, temperatures will rise, strengthening nighttime inversions and leading to fog formation, particularly in northern valleys and Spokane. In addition, smoke from nearby burns could cause hazy skies, especially over eastern Washington and the Palouse.
Eastern Washington is set to experience several days of calm, clear weather before a shift in conditions this weekend. Local meteorologists are predicting tranquil conditions through Saturday, with temperatures remaining mild and little to no precipitation. However, a significant change in the forecast is expected by Sunday, as rain and snow move into the region, bringing cooler temperatures and potential travel disruptions.
Calm Weather Through Saturday
For the next few days, residents of Eastern Washington can expect mostly dry conditions and relatively mild temperatures. Highs are forecast to be in the upper 30s to mid-40s across most of the region, with clear skies and light winds. This period of quiet weather offers a brief break before the more active weather system arrives over the weekend.
While daytime conditions will be pleasant, overnight temperatures will dip into the 20s and low 30s in many areas, so residents should prepare for chilly mornings. However, there are no major concerns about freezing rain or icy conditions during the daytime hours, which could impact travel.

The calm will give way to a more unsettled weekend forecast. Starting on Sunday, Eastern Washington will begin to experience the effects of a low-pressure system moving through the region. The system is expected to bring a mix of rain and snow to parts of the area, particularly in higher elevations and mountainous regions. Snow is likely to accumulate in areas above 3,000 feet, with mountain passes potentially receiving several inches of snow, leading to hazardous driving conditions in some areas.
In the valleys and lower elevations, the precipitation is expected to fall as rain, but as temperatures drop, a wintry mix could develop, especially in the early morning hours on Sunday. The wet weather will likely continue through Monday, with the possibility of snow in more localized spots, depending on the timing of the system and its interaction with colder air.
Potential Travel Disruptions
The biggest concern for travelers this weekend will be the potential for slippery roads, particularly in the mountain passes, as well as reduced visibility due to rain and snow. Drivers planning to travel along highways such as I-90, US 2, and US 395 should monitor road conditions closely and be prepared for winter driving conditions in higher elevations. Chain requirements and road closures are possible as snow accumulation increases.
In addition to mountain travel, areas closer to the Columbia Basin may see rain, which could lead to localized flooding in low-lying areas, especially if heavy rain falls in a short period of time. It’s advised to avoid driving through flooded areas and to stay updated on weather alerts from local authorities.
Long-Term Forecast
Beyond the weekend, weather patterns in Eastern Washington are expected to remain unsettled, with more rain and snow possible throughout the first part of the coming week. Temperatures will likely remain below average for early November, with daytime highs generally staying in the low 40s to low 50s.
While the region is no stranger to fall weather, this weekend’s system could be a reminder that winter weather isn’t far behind. Residents are encouraged to prepare their vehicles for winter driving, check heating systems, and stock up on supplies as the colder months approach.
While Eastern Washington enjoys a few days of quiet weather leading into the weekend, a shift to rain and snow is expected to arrive on Sunday, bringing cooler temperatures and potential travel disruptions.
As always, it’s important to stay informed on the forecast and any weather advisories, especially for those planning to travel over the mountain passes or during the early hours when snow could accumulate. With conditions shifting quickly, be sure to check local forecasts and road conditions before heading out this weekend.
