Weather 1-24-17


Our wet and active weather will continue today as most of us will see a transition to rain later on with snow continuing in the mountains. What we’re seeing is a mammoth Gulf of Alaska low pressure trough directing a deep feed of subtropical moisture around its southwestern flank into Washington and Oregon.

Tonight a cold front will cross the Cascades and push across the forecast area west to east overnight for one last shot of significant precipitation at and immediately ahead of the front. By early Thursday, most of the precipitation will be concentrated into extreme Eastern Washington and the Idaho Panhandle.

A mild and wet weather period will continue on Friday night and into Saturday as another large system brings 1-3 inches of snow to the Wenatchee Valley with heavy amounts of snow expected in the mountain passes. Our atmospheric river of moisture continues on Saturday night through early next week with a wintry mix of precipitation throughout the period.
