The waning gibbous moon will block out the fainter meteors this year. 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 the night of the 21st and morning of the 22nd. Meteors will radiate from the constellation Ursa Minor, but can appear anywhere in the sky.
