Here is my weekly weather quiz question for the last time. “What is a “Sea Breeze?” Here is the correct answer. A Sea Breeze is a thermally produced wind blowing during the day from a cool ocean surface onto the adjoining warm land, caused by the difference in the rates of heating of the surfaces of the ocean and of the land.

An Upper Level High Pressure Ridge (“Arch” shape) strengthens  over us bringing more sunshine and intense heat. The graphics for days 1-3  show no frontal systems near the Pacific Northwest. The graphics for days 3-7   Wednesday through Sunday show a cold front to our northwest next Wednesday then moving in between next Thursday and Thursday night.

Here is my weekly weather quiz question for the last time. “What is a “Sea Breeze?” Here is the correct answer. A Sea Breeze is a thermally produced wind blowing during the day from a cool ocean surface onto the adjoining warm land, caused by the difference in the rates of heating of the surfaces of the ocean and of the land.

____________

An Upper Level High Pressure Ridge (“Arch” shape) strengthens again over us bringing more sunshine and heat. The graphics for days 1-3  show no frontal systems near the Pacific Northwest. The graphics for days 3-7   Tuesday through Saturday show no frontal systems sliding into the Pacific Northwest through the period. There will be a cold front to our northwest next Wednesday then moving in between next Thursday and Friday.

Here is my weekly weather quiz question. “What is a “Sea Breeze?”

____________

An Upper Level High Pressure Ridge (“Arch” shape) strengthens again over us bringing more sunshine and heat. The graphics for days 1-3  show no frontal systems near the Pacific Northwest. The graphics for days 3-7   Sunday through Thursday show no frontal systems sliding into the Pacific Northwest through the period. There will be a cold front to our northwest next Wednesday then moving in next Wednesday.

Note: Please be extra careful with fireworks. It’s very dry and we’ve already had some brush fires locally.
