The Ursids is a minor meteor shower producing about 5-10 meteors per hour. It is produced by dust grains left behind by comet Tuttle, which was first discovered in 1790. The shower runs annually from December 17-25. It peaks this year on the night of the 21st and morning of the 22nd.
The second quarter moon will block many of the fainter meteors but if you are patient, you might still be able to catch a few of the brighter ones. Best viewing will be just after midnight from a dark location far away from city lights. The Meteors will appear to radiate from the constellation Ursa Minor, but can appear anywhere in the sky.
