A high pressure ridge (Shaded “Arch” shape with blue arrows) has moved to the east a bit, but still centered over Oregon, (see blue arrows curving from the northeast) and a thermal trough of low pressure (dashed line along the Oregon coast) our weather pattern will remain stable. We’ll have chilly nights followed by pleasant days with sunshine and average temperatures. The change Friday will be to an increasing chance of rain.
