THE PILOT SAID THAT AT ROTATION, THE PLANE HIT WIND SHEAR FROM 260 DEG, THAT LIFTED THE LEFT WING. DIRECTIONAL CONTROL WAS LOST AND THE AIRPLANE SETTLED BACK ON THE RWY. THE LEFT MAIN WHEEL STRUCK A SNOW BANK AND THE ACFT SPUN LEFT 180 DEG. THE TAIL SECTION WENT THROUGH THE SNOW BANK AND THE PLANE DEPARTED THE RUNWAY TO THE LEFT.
