Here is my weekly weather quiz question for the last time. What is the “Magnetosphere? ” Here is the correct answer. Magnetosphere: In solar-terrestrial terms, the magnetic cavity surrounding the earth, carved out of the passing solar wind by virtue of the geomagnetic field, which prevents, or at least impedes, the direct entry of the solar wind plasma into the cavity
________________
An Upper Level High Pressure Ridge (“Arch” shape) builds in toward the coast bringing warmer air to the Pacific Northwest. No chance of the much needed rain. The graphics for days 1-3 show the frontal system approaching the coast then falling apart as it moved into the Pacific Northwest. The graphics for days 3-7 Wednesday through Sunday 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 July 4th and 5th. Drink plenty of water and stay as cool as possible.
