There might be a bigger dicussion point here: about the demise of quality met data. I've noticed an inconsistantancy with the lenght of the TAFs. Sometimes I get 24 hrs, sometime not; well not for all airfields on my list. I've also noticed a definite pessimism in the TAFs compared to METARS and what eventually happens. Further, on Prune, we never received an authoritative answerwhy fronts were removed from SIG Wx charts. Instead of having a big picture to decyfer the TAFs we now have a small fuzzy picture to guess the future.
