Here is my weekly weather quiz question. What are “Iridescent Clouds?

_________________

An Upper Level Low Pressure Trough (“U” shape) has not moved so it’s still keeping us with the rain-snow chances. The graphics for days 1-3 show the next frontal system headed toward Oregon late today.  The graphics for days 3-7 show more complex frontal systems moving our way Sunday through next Thursday giving us chances of getting wet.
