Nullschool's Earth Wheather Visualiser has an aurora borealis forecast, based on OVATION: SWPC / NCEP / NWS / NOAA.
Link will show the forecast coverage / visibility at the time you're viewing it (rather than when I post the link), with a 30--90 minute advance visiblity (based on satellite observations at L1, a stable orbit between the Earth and Sun):
