Hi Gillis,
The first, best, clue is checking for thunderstorm activity,
which is responsible for most airborne LF noise. There are a
number of sites but the tried and true favourite for North
America is:

The fewer little ziggy-zaggies on the screen the better!
Daytime, any within a few hundred miles is bad news,
night-time you will hear ANY that are visible.
