Dry and stable weather will continue today with more fog and low clouds over the lower Columbia Basin and over some of the river valleys of northeast Washington and north Idaho. The remainder of the Inland Northwest will see one more sun-filled day with highs today in the mid 40’s.

The weather pattern will become decidedly wetter and unsettled starting tomorrow as a weak weather system moves through. This system will likely bring a mix of rain and snow to the northern valleys and light snow to the Cascades. We can expect a 30% chance of precipitation in the afternoon Wednesday and Wednesday night with highs in the upper 30’s.

A much stronger low pressure system is expected to arrive on Thanksgiving as the weather system taps into moist Pacific air. In Northcentral Washington there is a 50% chance of mainly rain mixed with snow shoers and a 50% chance Thursday night. Highs Thanksgiving day in the lower 40’s. We will see showery weather continuing into Friday with a 60% chance of rain or snow mainly in the morning with high temperatures around 40. This system will likely deliver moderate snows to the passes affecting holiday travelers.

Drier weather is expected to return by the weekend with partly cloudy skies and highs around 40 both Saturday and for travel day on Sunday. Dry, mostly cloudy weather is in the forecast for the early part of next week with high temperatures staying around 40 degrees.
