I'll be curious to see if this reverses the westward migration in the United States that we've seen over the past 100+ years. Large rust belt and east coast saw stagnant, if not declining, populations as new families moved west for better weather, mountains, cheap land, access to the west coast, ... the Great Lakes, Ohio, Upper Mississippi, and New England (and the Upper Colorado) watersheds are least likely to be impacted by severe droughts. Throw the Mid Atlantic in there, too, despite the increasing risk of severe tropical events.
