Air carrier First Officer reported receiving an ATC clearance to a waypoint that was not in the aircraft navigation database or Jeppesen publication; but was identified in the weather app on the EFB. ATC provided a heading to the waypoint.

Narrative

We were in the cruise phase of flight deviating for thunderstorms. ABQ cleared us direct STONE then direct RUSME. After confirming with the pilot monitoring (PM); I typed direct STONE into the FMS and proceeded direct to that fix. Shortly after proceeding direct to the fix we noticed that although the fix was to the west and made sense for our direction of flight; we received a low fuel message and the total distance in FMS for the flight did not make sense. ATC then queried us to verify we proceeding direct STONE. After verifying the correct spelling for STONE; which was correctly spelled in our FMS; ATC assigned us a heading to get us going in the correct direction. After checking with our Jeppesen pubs we could not find a fix spelled STONE that was located in North America but DID show a fix called STONE located in North America using WSI. We checked with Dispatch and they also could not find a fix called STONE. In summary; the correct fix of STONE was in our WSI app but not in our Jeppesen publications or FMS.
