This morning we had the kind of precipitation that Seattlites often call "not really raining." The expression applies to two distinct types of weather. One is a slow drizzle. The other is a light mist with drops so tiny that they don't fall to the ground but waft with the air currents and pool on the surface of your skin. It's not really raining, but more like a cloud coming to ground.
It's not fog - you can see things, sort of. Here's the 520 bridge.
In fact, the not-really rain illuminates things that we overlook on clear days, such as the tiny webs of spiders, still active in February.
