Here is my new weekly weather quiz question. What is a “Mesocyclone? ”
________________
An Upper Level High Pressure Ridge (“Arch” shape) strengthens bringing much warmer air to the Pacific Northwest. No chance of the much needed rain. The graphics for days 1-3 show no frontal systems approaching the coast. The graphics for days 3-7 Friday through Tuesday show no fronts pushing into or through the Pacific Northwest during rest of the period.
Note: Be prepared for temperatures from the upper 90s to 100 degrees for today July 4th and tomorrow. Drink plenty of water and stay as cool as possible.
