Another upper level high pressure ridge (Shaded “Arch” shape with blue arrows) is moving in clearing the skies and ending the chance showers and possible thunderstorms for a while. By the middle of the week a frontal system approaches the West Coast. By Friday it looks like a frontal system will be moving through the Pacific Northwest bringing more shower chances. The end of the weekend another frontal system will be approaching from the northwest probably making landfall sometime Monday.

An upper level trough of low pressure (Shaded “U” shape with blue arrows) moves closer increasing the marine airflow for more clouds and cooler temperatures. There were showers and thunderstorms in Oregon Wednesday but they stayed well North of the Southern Willamette Valley. The Eugene area saw smoke Wednesday from a Slash/Burn in Douglas County. It was particularly strong in South Eugene. A frontal system is heading our way bringing showers and possible thunderstorms with it. A  frontal system is shown approaching the coast bringing increasing chances of rain to the Pacific Northwest. Next week another frontal system approaches the West Coast.
