Will You See the Total Lunar Eclipse Tonight?

 Maybe.

Tonight around midnight our time, the moon will be entirely in the earth's shadow. 

 A total lunar eclipse.  During such periods, the moon often develops a red color, sometimes leading to the name "blood moon."

The big issue tonight will be clouds.....but don't give up yet!

The visible satellite image right before sunset shows the problem (see below).   Unstable air with a lot of cumulus clouds moving into western Washington.  Solid clouds on the western slopes and crests of the Cascades and Olympics.

But hope is not lost.  There is a large clear zone east of the Cascades, and over the western lowlands, the cumulus clouds are scattered and MOVE, and thus the moon will come in and out.

The radar image at the same time shows the situation well.

What will things be like during the eclipse?  The timing is shown below.  The total eclipse will be from roughly 11:30 PM to 12:30 AM.

The cloud forecast of the UW WRF model for midnight suggests that some of you...even in the west, will see it! 

I know I will be looking.....I love eclipses!

Finally, why does the moon look red during total eclipses? 

The same reason the sun looks red when setting:  light from the sun has to go through a lot of the atmosphere. Blue and green colors are scattered more than reds by atmospheric molecules.  So those colors are lost, leaving the longer-wavelength reds.
