There is mention of sonde data, there is no mention of pilot reports from a 757, but there is this:
“ Prior to liftoff, pilots conducting test flights reported some vertical wind shear earlier that morning, but it was within acceptable limits. Obviously, vertical wind shear must have dramatically increased after 12Z (conditions were considerably worse during liftoff). According to the President's Commission Report:
"At approximately 37 seconds, Challenger encountered the first of several high-altitude wind shear conditions, which lasted until about 64 seconds. The wind shear created forces on the vehicle with relatively large fluctuations. These were immediately sensed and countered by the guidance, navigation and control system.”
