Finally - an update on Comet ISON and what may be coming next

6. I put ISON into the NASA ephemeris interface here:

http://ssd.jpl.nasa.gov/horizons.cgi

and that says the declination by midnight GMT Dec 23rd (the start of the week or so it's closest to Earth) is +38 degrees 56 minutes - just enough to make it circumpolar for me at about 51 degrees north, if I remember the meaning correctly (ie 90 degrees minus your latitude). By Dec 24th it's 42deg26'; Dec 25th 46 degrees. By Dec 26th it's 49deg37', which makes it just circumpolar for New York.

There's an online star chart here: http://www.fourmilab.ch/yoursky/cities.html where you can put in a major city, or your own latitude and longitude.

On edit: reading the full link in the OP, it looks like they don't expect dust and ice production for more than a week or so. Looks like I'm out of luck - too far north to see anything by then, even if I'm up at 5 in the morning.
