Here is my weekly weather quiz question. In aviation what does “MVFR” mean?
________________
An Upper Level Low Pressure Trough (“U” shape) keeps our weather pattern stable with a bit above normal temperatures. The graphics for days 1-3 show a cold front moving into the Pacific Northwest Wednesday, but it won’t be a rain producer. The graphics for days 3-7 Saturday through Wednesday show a frontal system to our north next Monday.
