Very abrupt weather (wind) transition. Erratic wind behavior (Still present after AAU 1)

During few online flights the PMDG 737 for the last few days I’ve cought extrimely abrupt and violent up to 50 knots wind behaviour at FL340-370.
So, as a result, I’ve got penalty in my VA for speed exeded.
I hope, this problem will be solfed in nearest future!
