Seattle has many words for rain.
I encourage all of you to utilize the Beaufort Rain Scale where at any time the term to use could be Force 1: Scotch Mist; Presence of wet in the air, hovering rather than falling. You can feel damp on your face. But if you supinate your hand, nothing lands on it.
Associated Phrase: "I think it's trying to rain." (P.Meek)
