The peak in activity will be tonight, but usually, the nights before and after the peak is also good. Yesterday evening was cold and clear and the moon is new today and doesn't interfere with the viewing conditions this year at all, so if only local weather conditions co-operate tonight, it should be a spectacular sight.
Below is two photos from this morning showing two of many meteors that streaked across the sky accompanied by pulsating auroras. The planet Jupiter and the Pleiades can be seen over the barn.
