A large upper level area of low pressure that has two smaller areas of low pressure nested and rotating around inside of it will continue to influence Northcentral Washington weather today. In addition, the pressure gradient remains rather cluttered and intense today due to this setup so some gusty winds remain in the forecast especially for the Waterville Plateau, Columbia Basin and Wenatchee Valley. Because of that, we can expect mostly cloudy skies for Friday with a northwest wind 10-20 mph with possible gusts to 30 mph, afternoon highs in the mid to upper 60’s.
As we kick off the long Memorial Day weekend on Saturday, a ridge of high pressure moves into the region, bringing the start to a warming trend and mostly dry conditions all the way through next week. We will see mostly sunny skies on Saturday with just light winds and high temperatures warming up into the lower 70’s.
Warmer temperatures are expected for both Sunday and Memorial Day Monday but we will see more clouds too with highs in the mid to upper 70’s.
Moving into the week, temperatures continue to rise each day under sunny skies, eventually reaching 5-10 degrees above seasonal normal. The afternoon highs around Northcentral Washington will be warming into the upper 70s to mid-80s by mid-to-late week.
