SPOKANE, Wash. - The first snow of the season looks likely for Spokane Thursday morning.
As of Tuesday afternoon, cold air is funneling down from the Yukon via the Okanogan Valley and winds are still gusting from 20 to 30 miles per hour, however they will decrease overnight.
The cool air plus partially clearing skies and temperatures dropping into the 20s will make for a frosty Wednesday morning with patchy fog.
After the fog burns away Wednesday, Spokane will stay cool as cold Canadian air continues to spill southward with Spokane highs expected to be in the mid 40s (normal is 53).
Wednesday night, a Pacific storm loaded with moisture will pour onshore reaching the Cascades about midnight. Much of the energy will push northward into Canada and as the saturated air layers over the freezing air near the ground, the result will be snow.
Thursday's showers will begin as snow at lower elevations including Spokane and points northward.
At this point, it looks like the Spokane area can expect an inch or less with up to 3" as far south as Wenatchee and Sandpoint. Showers will change to rain during the day.
Halloween will be breezy and rainy.
