I am not a huge fan either...I would never do that in a forecast, especially if forecast for a smaller geographical area (say Connecticut).
In this situation, I was just referring too the max range...but if I was tying a forecast to that the range would have been like 18-24'' for max end with the next area 12-18''.
But i'm totally with you...I am not a fan of wide ranges...especially stuff like 2-5'' or 3-7''. My professor used to harp on that alot...the difference between 2'' and 5'' is snow plowing and snow blowing and well not needed to do either.
I know landscapers HATE when they see ranges like that...it drives them nuts b/c it makes it difficult for them to plan
