It May Be Wet, But It’s Not Rain

It's only considered rain at .02" in diameter

That old saying: "If it looks like a duck, walks like a duck and quacks like a duck" doesn't hold true when it comes to the weather, at least not always.  All that "wet" out there may look like rain, but it's not, not really.

In the world of meteorology, it's not officially considered to be a raindrop until it reaches .02" in diameter.  I didn't get my ruler out yet, so I'm relying on my good buddies up at the Rancho Bernardo office of the National Weather Service to let their computers do the measuring and so far the machines are still calling what we're getting "drizzle and mist."

It actually looks and feels a lot wetter than it really is.  There has been very little accumulation as of the noon hour, only a trace to about one or two hundredths of an inch at most.  Of course, if this keeps up all day, we may actually see a tenth or more in some spots, even if it never really rains.

Now, there is a slight chance, about 20%, that some of you could see an actual shower or two before the day is over, but those aren't really good odds.  They will improve a little overnight, as the chance of rain for Tuesday increases to 30%.  Heck, there's even a slight chance of some thunderstorms moving in as the cold core of the storm rolls over us tomorrow afternoon, but for now you'll just have to put up with the dampness we're getting from the heavy drizzle.  Sure hope you packed the umbrella I advised you to take along early this morning.
