My thoughts too, since Svarin pointed out the WRG: WRN: difference
Funny how you ask a few questions and something pops up that seems to make a little sense: IE - normally speaking, one would expect an aircraft to avoid weather likely to be very uncomfortable or dangerous.
Any issue with the aircraft resulting in a flight proflle that is not ideal would only incease any risk from bad weather - irrespective if the issue cropped up before or during the worst of the weather - BUT if the weather 'alone' was not enough to be the decisive influence without any other problem, then any potential issue arising independently or because of (Turbulence) would certainly explain subsequent events.
Out of interest, if icing is a potential cause of the airspeed inconstencies is it equally possible a wiring fault could casue the same thing?
Looking at a whole, it seems more plausible than some of the other ACARS messages since some appear unrelated (directly) to having problems with the pitots and probes - or perhaps that was the cause alongside a seperate fault unrelated?
