A cool upper trough will descend out of Canada this afternoon bringing breezy north winds around the Inland Northwest. Our low-level air mass is quite dry, and it will become even drier late this afternoon into this evening as Canadian air surges into our region. By late afternoon, north or northeast winds of 10 to 20 mph will be common for the Okanogan Valley, Columbia Basin, Moses Lake area, and the West Plains. Northcentral Washington weather for today calling for sunny skies with a west breeze 5-15 mph with highs this afternoon 60-65 degrees.
North winds will blow all day Tuesday raising concerns for blowing dust, scattered power outages, rough water on area lakes, and heightened grass fire potential. Our region will be caught between deep low pressure over Nevada and high pressure surging into Montana. Sustained north winds of 15 to 30 mph with gusts locally as high to 35 mph will blow from morning into the evening across most of central Washington. Columbia Basin and Wenatchee Valley forecast calling for sunny skies tomorrow with a north wind and highs in the lower 60’s.
Still a bit breezy on Wednesday too with sunny skies, a northeast breeze 5-15 mph and warmer, with afternoon highs in the mid to upper 60‘s.
Thursday through Sunday an unusually strong upper-level ridge of high pressure will take over our weather pattern with lots of sunshine and unseasonably warm temperatures, almost 15-20 degrees above normal. Forecast each day calling for sunny skies with highs on Thursday in the upper 60’s to lower 70’s, lower 70’s on Friday and afternoon temperatures this weekend will be pushing 80 degrees.
