Advisories: NONE AT THIS TIME.

We have been under a blocking high pressure ridge (“Arch” shape covering the Pacific Northwest) that kept us under Easterly hot airflow. The ridge has weakened and is moving away from us to be replaced by a cool trough of low pressure. A frontal system is headed our way and will increase moisture and cloud cover in the area. Another frontal system will move in for the weekend which could even produce some showers.
