If you're only dealing with a partial screenful of data, you could cut
and paste it into a "here" document:

    $ grep foo <<EOF
    > { paste stuff to be grepped here }

If you have too much data to paste into a here document, I'm afraid
that you're out of luck.  I doubt that bash saves the output anywhere
due to the performance hit and the need to deal with both stdout and
stderr seperately.  It sure would be a handy thing to have on the few
occasions when you need it though.
