Why Do They Continue To Abbreviate Weather Products? Can We As A Community Change This?
The language of aviation is terse, compressed and intended to leave minimum room for interpretation or misapprehension. 

It makes heavy use of formulas, themselves intended to to be unambiguous, but which are not always obviously and immediately meaningful to those who are unfamiliar with the language. 

This is the norm for potentially critical communication in all fields that I'm aware of - the military, medicine and throughout the transportation industry.

The users of this language are trained in it; being familiar with it is an essential part of their competence. 

Language, interfaces, procedures and tools in aviation don't need to be user-friendly, they need to be utterly precise, be usable in difficult circumstances, and on every occasion they're used have exactly the same outcome.

It's possible that an aviator has failed to understand a weather forecast and died as a result, but a weather reports that allowed themselves the liberty of free expression would kill a lot more than that.
