The show should be at its best on Sunday night through into Monday morning, with a peak rate of around 10-20 meteors per hour. The light from the waxing moon will be less of a distraction after midnight.
(At that ZHR, you might expect to see half a dozen meteors per hour... not exactly dazzling, but worth keeping half an eye out if you're observing anyway - Rick)
