This works, although it's possibly not the cleanest solution.  It
messages the upgradeable packages and also notifies you via desktop
notifications.

(defun th/package-check-upgrades ()
  (interactive)
  (cl-flet ((check ()
                   (package-menu-mark-upgrades)
                   (let ((pkgs (mapcar #'car (package-menu--find-upgrades))))
                     (when pkgs
                       (message "PACKAGE UPGRADES: %s" pkgs)
                       (require 'notifications)
                       (notifications-notify :title "Emacs Package Upgrades"
                                             :body (format "%s" pkgs))))))
    (if (get-buffer "*Packages*")
        (with-current-buffer (get-buffer "*Packages*")
          (package-menu-refresh)
          (funcall #'check))
      (save-window-excursion (list-packages))
      (with-current-buffer (get-buffer "*Packages*")
        (funcall #'check)))))

If you want, you could run that from an idle timer.
