Narrative:

ATIS called wind 330 at 3 KTS. We were landing on runway 7R trailing a B737 (unknown which model i.e.: 700; 800) that was landing on runway 7L. I would say we were about 1 mile in trail. At around 700 ft MSL we started to encounter what we are fairly certain was wake turbulence from the B737. We changed our approach path to fly higher; and we were clear of the turbulence until around 50 ft above touchdown; within the first 1/4 of runway 7R. At that point we encountered fairly strong wake and almost elected to go around. I believe that we were allowed to trail too close to the B737; on the parallel runway with the light winds blowing the wake towards us. Prevention: possibly look into the amount of wake the newer larger models of B737 are creating; and of course increase the space between aircraft of our class and those.
