A shortwave trough of lower pressure is pushing into Vancouver Island early this morning. High clouds are increasing ahead of this minor weather feature east of Cascades in the Columbia Basin and Wenatchee Valley. High pressure off the Pacific Coast is still our main weather influence though bringing much warmer temperatures right through the upcoming weekend.

Northcentral Washington weather today will be mostly cloudy and mild with afternoon high temperatures in the mid to upper 70’s. The pressure gradient will tighten up a bit with winds breezy through the Cascade gaps this evening with gusts up to 20-25 mph possible for places like Wenatchee, Chelan, Vantage, the Waterville Plateau and down the Okanogan Valley.

Thursday marks the beginning of real warming trend with mostly sunny skies, light wind and highs in the upper 70’s to around 80 degrees.

The ridge of high pressure strengthens Friday, Saturday and Sunday bringing sunny skies each day with high temperatures in the lower 80’s Friday, mid 80’s Saturday and all the way up to the upper 80’s on Sunday.

Our weather begins to change on Monday with mostly sunny skies and slightly cooler temperatures with highs near 80 degrees.

By Tuesday, an area of low pressure will move in bringing very windy conditions, a slight chance for sprinkles and afternoon high temperatures around 70 degrees.
