An elongated upper trough of low pressure over the western U.S. will continue to provide a southerly flow over the region this morning with a band of light snow over North Central and Northeast Washington. Weather forecast for the afternoon into the evening shows clearing skies, calm wind and afternoon high temperatures, still below normal, in the lower 30’s.

A much larger weather system moves our way on Tuesday afternoon bringing a 30% chance of snow in the afternoon with highs once again in the upper 20’s to lower 30’s. The chance for snow goes up to 80% Tuesday night with snow amounts in the 3 to 5-inch range possible for Wenatchee, Leavenworth, Chelan, Methow Valley, Omak, Republic and the Waterville Plateau.

This weather system is a slow-mover and will still bring a 70% chance of a wintery mix on Wednesday as well with afternoon high temperatures a bit warmer into the mid 30’s.

Thursday and Friday will be quiet weather-wise with partly cloudy skies Thursday and warmer with highs in the mid to upper 30’s while Friday will be mostly sunny and mild with highs again in the upper 30’s.

There is decent agreement that the Polar Jet Stream will consolidate with the southern jet next weekend. The storm track will likely shift further north giving Oregon, Washington, and the Idaho Panhandle a better shot of significant precipitation. At this time, it looks like rising snow levels may limit the amount of lowland snow accumulations for the Wenatchee Valley, Columbia Basin, Palouse, and Spokane area.

For Northcentral Washington this weekend, expect a 30% chance of rain mixed with snow both Saturday and Sunday with afternoon highs in the mid to upper 30’s.
