I have an Acurite with outdoor sensor that I got as a gift. The indoor is right on, but the outdoor temp is 6-7 degrees LOW based on comparisons with multiple sources including another wired thermometer to the outside, also in the shade. That one always reads exact to my various other sources. It's just annoying and realize I should just replace it but Ive been looking for a weather station that gives me wind speed and direction and something of higher quality but not over 300 to 400$.

I use the cheapo radio shack indoor/outdoor thermometers and they drift as
well. When new, the outside probe and inside probe matched, but not
anymore. I think something happened with the insulation of the wire or the
sensor which is potted in a little probe.
