Could be a bad CV axle, but also could be something to do with worn out bushings in the suspension its hard to say wihtout looking at it unfourtanetly.

Tire developed a flat spot from sitting for a long period. Very common in frigid areas.
The tire slowly returns to normal shape as the rubber warms from flexing while driving. If tires are original to vehicle, very good time to replace.

Could be a bad strut assembly. Take it to an auto shop for a diagnoses.

Is it a rapid thump or less often? If it's rapid, could just be a flat spot on your tire from sitting in the cold, otherwise probably suspension.
