Question about externally editing in Photoshop then saving but the files not showing up in catalog

When I am in Lightroom and I choose edit in Photoshop then I save the file, I would like the file to automatically show up in my Lightroom catalog.  It shows up if I save as a tiff like I set up in my preferences, but not if I save as a jpeg.  I would like for the jpegs to also show up in the catalog.  Is this possible?

Thanks,

Jennifer
