A ridge of high pressure parked in the eastern Pacific will provide a very quiet and unseasonably warm weather pattern through the entire 7-day forecast. The ridge will allow a couple of very weak disturbance to move through but for the most part Northcentral Washington will just see increasing clouds on Wednesday and once again on Saturday.
Columbia Basin and Wenatchee Valley today will be mostly sunny and mild with afternoon high temperatures in the lower to mid-70’s.
A warming weather trend begins on Tuesday with sunny skies and afternoon highs in the upper 70’s.
Our broad, flat ridge of high pressure intensifies on Wednesday with a few more clouds but warmer temperatures with highs around 80 degrees.
Thursday and Friday will be mostly sunny and warm with afternoon high temperatures in the upper 70’s to lower 80’s.
By Saturday a weak disturbance moves the ridge of high pressure bringing partly cloudy skies and cooler temperatures with highs in the lower 70’s. A beautiful weather day is on tap for Sunday with sunny skies and mild temperatures with highs in the mid-70’s.
