The Geophysical Institute at the University of Alaska Fairbanks is predicting a geomagnetic storm for Wednesday and Thursday of this week (July 12th & 13th). Strong northern lights may be visible between 10 PM and 2 AM in parts of the northern US, especially from points of high elevation, clear views of the northern horizon and low light polution.
I have been chasing Aurora for quite a few years. From my experience forecasts this far out are rarely accurate. Take this with a large grain of salt.
