Hi Daryl,
I too get some "interesting" products mailed to me, and I noticed
the exact same duplication of the "SPECIAL NCEP DISCUSSION" that
you got. Off hand, I'd say this happens on occasion with a variety
of products--such as individual forecast office discussions,
NCEP HPC Extended Forecast Discussions, et al. I surmise that the
product is being submitted twice (or more, sometimes) by the originating
site for some reason. It's not just KWNO as, again, I have seen
duplicates from local offices.
One time, though, we somehow had two instances of pqact running--which
guaranteed that each product I received via email was duplicated.
