Temperatures for the upcoming week will remain above average, especially as we head toward the Thursday/Friday time frame; however, a trough of low pressure diving across the Pacific Northwest will create colder changes for us by next weekend.

That trough will deepen to allow moisture to increase, creating rain chances from Thursday through Saturday. Temperatures aloft will be too warm to support any wintry precipitation, but that could change.

As the trough deepens, a polar plunge of air will head south across the northern plains. We're expecting a modified cold air mass to reach us by Saturday night. If the moisture lingers into Sunday, we could see a light wintry mix of precipitation. The latest information from our computer models has most of the moisture moving east by the time the cold air moves in.

This will remain a timing issue, and we'll continue to update you throughout the week.
