Here is my weekly weather quiz question. What is “Steam Fog?”
____________
An Upper Level High Pressure Ridge (“Arch” shape) rebuilds bringing sunshine and warmth. The graphics for days 1-3 show a weak cold front sliding through Saturday. The graphics for days 3-7 Monday through Friday show a weak cold front will be moving into the Pacific Northwest between Tuesday and Wednesday.Then a complex frontal system will be offshore and moving in next Friday.
