Here is my weekly weather quiz question. In meteorology what does the term “diamond dust” refer to?

Advisories: NONE AT THIS TIME.

An upper level trough of low pressure (“U” shape on orange line) off Vancouver will swing through today with more clouds. A short lived high pressure ridge (“Arch” shape on orange line) will follow and warm us up a bit. The Perseid meteor shower peaks through Saturday, but the nearly full moon will probably spoil the show. A frontal system will approach the coast Sunday and move in bringing the chance of showers to the coast and Southern areas of Oregon Monday.
