It depends on the composition, size, and surface characteristics. For a typical stony meteoroid (1m diameter, albedo 0.04) at approximately 1 AU, solving the Stefan-Boltzmann equation gives a temperature of about 20�C. These things absorb plenty of energy from the Sun, and tend to be poor emitters.
For normal meteorite falls, the internal temperature of the object is determined mainly by the air temperature while it is in the dark flight phase. 0�C to -20�C is probably most common.
