100% chance of rain — but do I need an umbrella?

As you prob­a­bly know, I live in Portland—where it rains. A lot.  There are cer­tain times of the year where it rains every day for weeks on end.  If you live here, the rain is bear­able and quite nice.  It’s no big deal.  It amounts to a lot of sprin­kling, maybe a fog that is a lit­tle too heavy to stay in the air.  As the say­ing goes, the only ones with umbrel­las are the tourists.

That being said, there are a few rare days when you really do need an umbrella.  As yet, I have not found an iPhone weather app that accu­rately shows this.  Most of those apps will tell you, quite hap­pily, that there is a 100% chance of rain all day:

When you hit the NOAA web­site, the story plays out a lit­tle dif­fer­ently.  It’s 100% chance of rain, but the vol­ume will end up being about 0.06 inches.  That is hardly umbrella-level rain.  (Click the image for more detail.)

I’m still search­ing for an iPhone weather app that con­veys this par­tic­u­lar chunk of the data set.  Do you know of one?
