It seems to me that the key phrase in = the letter is=20 this:
 

"If the=20 composite information indicates=20 to a = reasonable and=20 prudent pilot that he or she will encounter visible = moisture=20 at freezing or near = freezing=20 temperatures and that ice will adhere to = the=20 aircraft along the proposed = route and=20 altitude of flight,=20 then known icing conditions=20 likely=20 exist."

 

In = other words,=20 in addition to there being the potential for icing (moisture and = freezing=20 temperatures) the pilot needs to determine that ice will adhere to the=20 aircraft. 

 

How should a=20 reasonable and prudent pilot determine "that ice will adhere to the=20 aircraft"?   Pilot reports?  = Forecasts of=20 icing?

 

It = seems to me=20 that this allows for a lot of retrospective second guessing on the part = of the=20 FAA.
