I know others on the list are saying that it may be 
cedar serviceberry rust, but I'm fearing the worst.
Without looking at it, your description coupled with
the warm rainy weather makes it sound a lot like fire 
blight.  

Fire blight is pretty serious, so you should take some
steps to make sure that this is or isn't the problem.
The first key to identification is the shoots, which
droop and look as if they've been scorched by fire.

The next major ID characterisitc is the reddish brown
streaks found beneath the surface of the sapwood.  You
may also notice cankers forming along the branches,
forming "blisters" along the stems or trunk.

If in its early stages, it can be checked by pruning
off the affected branches about 8" below the cankers
or blighted twigs.  Make sure that you sterilize your
pruners between each cut.

They're supposed to be hardy to zone 4, but I'm not sure where
you're located.  'Elegans' isn't as vigorous as the species,
however, so this may be your problem.  They also don't
like wet soils, so if drainage is a problem...
