But at least on Monday, the forecast was not for rain.
It was for heavy rain.
One of the consequences of Seattle's annual Rain Festival
(runs from January 1 to December 31)
is that we get plenty of potential for rainbows.
A friend of mine was lucky enough to capture a photo of
a puzzling triple rainbow this past weekend.
The primary and secondary rainbows
we all know about,
but what's that vertical rainbow shooting straight up into the sky?
(And observe that the landing point of the rainbow is clearly
in front of a house and trees, so go get your pot of gold.)

Reflection rainbows occur when light bounces off a body of water
before being refracted by rain droplets.
The body of water acts like a mirror and creates a virtual light source,
which results in a rainbow that is off-center from
(I find it interesting that there are some rainbow phenomena
that science is still trying to understand.
Only a few months ago did researchers figure out
how twinned rainbows are formed.)
Seattle weather celebrity (yes, we have weather celebrities here)
digs into the triple-rainbow phenomenon,
augmenting his analysis with Doppler radar,
because that's how he rolls.
