 This was published yesterday. As major outside event literally just happened, the attempted assassination of Donald Trump, this is likely to provide a polling boost for Trump, as it did for Ronald Reagan back in 1981. The most likely major outside event that could still occur are that an illegal alien, perhaps a foreign terrorist, kills or wounds a great number of U.S. civilians at home, or that another foreign war erupts that drags the U.S. in. Neither of these events is likely to rebound to Joe Biden's polling favor.
