if either or both of them were climbing or descending it would have been due to weather.
Just speculating ... I believe CBs in that area can have very high tops, so it would be unlikely that any one of them would be changing levels due to weather.
Local news reports said that the Legacy was cleared to fl 330 and the 737 to 360.
Again, I am not familiar with the region, but based on the probable route of both airplanes, shouldn't the Boeing be flying at some odd level and the Legacy at some even one?
