A gigantic area of high pressure in the Eastern Pacific continues to build and will continue to dominate our weather bringing sunny skies, light winds and unseasonably warm temperatures. Expect sunny skies in our Tuesday forecast with a bit of a north wind 5-15 mph and afternoon high temperatures in the lower 80’s.

Wednesday will see a few more clouds as a weak area of low pressure over the Palouse slowly moves east, dragging clouds with it. The Wenatchee Valley can expect mostly sunny skies and lighter winds than today with afternoon highs tomorrow once again into the lower 80’s. One weather feature of note will be gusty winds going down the Okanogan Valley today and Wednesday.

Thursday morning through Sunday morning, the strong ridge of high pressure over the Gulf of Alaska will continue to build into the Inland Northwest with the upper flow becoming more northeasterly across the region. This upper flow pattern will continue to influence Northcentral Washington with a strong warming trend, which will continue into the weekend. For Thursday, expect sunny skies, very light wind with highs near 80 degrees.

Our weather pattern really heats up on Friday with sunny skies and afternoon high temperatures in the mid to upper 80’s. Saturday and Mother’s Day Sunday, look for sunny skies, light wind and afternoon highs in the upper 80’s to near 90 degrees.

By Monday morning, the upper ridge axis will begin to flatten and shift east and south, which will increase mid and high level clouds across the region with a subsequent decrease in daytime high temperatures as well. Under mostly sunny skies Monday, expect afternoon highs to top off in the mid 80’s.
