The arrival of winter brings with it questions about the weather patterns and snowfall predictions across the region. According to meteorologist Steve Van Horn from the National Weather Service in Spokane, the expectations for this winter forecast lean towards moderately more snowfall and slightly cooler temperatures compared to last winter. The previous winter was influenced by El Niño conditions, which typically lead to drier and warmer weather. However, the region is now seeing a shift back to La Niña conditions, which have historically led to wetter and cooler winters, although this current La Niña is considered relatively weak. This shift suggests that local residents may need to prepare for more frequent snow shoveling duties this winter than last year.
When considering specific snow expectations for the Lewiston-Clarkston area, it is anticipated that snowfall will measure between 15 to 20 inches throughout the winter season. This amount represents a marginal increase from the previous year’s total of 13.89 inches, which was particularly low in December and light in both January and February. In contrast, the expectations were different for the Palouse region, where Moscow is anticipated to receive significantly more snow, estimated at around 50 to 60 inches. Pullman, located just a short distance away, is projected to receive about 35 to 40 inches. The variations in snowfall amounts between these areas can largely be attributed to their differing elevations and proximity to mountainous terrain.
In the Camas Prairie area, the snowfall predictions are even more substantial, with expectations ranging from 90 to 100 inches for the season, surpassing the average of 90.5 inches. Grangeville, a part of this region, has already recorded some early snow, though below the typical early season amounts. The forecast for the early weeks of December indicates milder conditions ahead, both in terms of temperature and snowfall, which is welcomed news for those eagerly awaiting winter activities such as skiing and snowboarding. Enthusiasts can look forward to early-season openings at regional ski areas, with some opening at the earliest times in decades.
As for temperature predictions, it remains uncertain how cold the winter will be. In Lewiston-Clarkston, residents are hoping to avoid a repeat of the severe cold experienced last January, which saw temperatures drop to minus 10 degrees—an extreme not felt in 35 years. Such harsh cold poses risks to local flora and can have a lasting impact on the winter environment. The warmer climate in Lewiston could stand in stark contrast to surrounding areas like Moscow and Pullman, particularly when memories of summer 2024 come into play. That summer registered as one of the hottest on record for Lewiston, illustrating how differing elevations and climates can lead to significant seasonal differences among nearby locations.
Indeed, the summer of 2024 brought record heat to Lewiston-Clarkston, with residents experiencing 21 days of extreme temperatures above 100 degrees. Comparatively, both Moscow and Pullman saw fewer instances of such heat, though they weren’t entirely immune. This temperature disparity underscores the pronounced climatic differences dictated by elevation and geographical features within the region. Such patterns have consequences not only for daily life but also for agriculture, which is sensitive to both seasonal temperature shifts and precipitation levels.
Finally, speaking of precipitation, the region has been recovering from a moderate drought, which affected water levels over the past water year ending September 30. Lewiston recorded just under 12 inches of precipitation, while Moscow noted even less—both figures falling short of their respective historical averages. However, the upward trend in precipitation for November bodes well for the upcoming water year of 2024-25, which is promising to be improved, consequently benefiting agriculture. As the winter unfolds, close attention will be paid to precipitation patterns and temperature fluctuations, shaping the landscape and lifestyle of residents across the region. Whether through snowy winters or hot summers, the diverse weather conditions contribute significantly to local culture and outdoor pursuits.
