We are seeing an increase in marine airflow which cools us down. The Upper Level High Pressure Ridge has weakened enough to allow the chance in surface air movement. The graphics for days 1-3 show surface low pressure moving eastward. The graphics for days 3-7 show a series of storm systems that will approach and try to move through the Pacific Northwest Saturday through next Wednesday.
