it is no rocket science to take one look at the MSLP chart, see the isobars very close together ( = strong winds), and to thus expect strong turbulence which that type of plane is poorly equipped for, in terms of both excess engine power and structural strength.
Unfortunately it's not that simple. When it happened to me, and to my mate in the Kinder Scout crash, the isobars showed no such pattern. Local venturi effect of terrain and overlying air masses can have a massive effect on windspeed over high ground.
