Environment - Non Weather Related; Procedure
We were departing Runway 22L in ORD. At the time ORD was landing Runway 28C. Just prior to our takeoff an A321 was landing Runway 28C which crosses over Runway 22L's takeoff roll path. At approximately 120-130 kts our aircraft suddenly and aggressively yawed right. This occurred prior to V1 but in the high speed regime. As pilot monitoring I double checked the engine and flight control indications. Everything was normal so I did not make a call out. The Captain (pilot flying) was able to return the aircraft to runway centerline and took off normally without any further issues.The winds during takeoff were reported 300 degrees at 8 kts. I believe that we encountered jet blast or wake from the aircraft landing Runway 28C.
