Weather category dots

I'm seeing several weather stations indicating LIFR (magenta dots), but all indications seem to say that the weather is CAVU. Looking closer, it seems that SkyVector automatically selects magenta if either the ceiling or visibility is not reported on the metar. I understand erring on the side of caution, but would it be better to use a different color (gray is used by NOAA) to accurately indicate an incomplete picture rather than assigning an incorrect designation?

Weather symbology labels needed

I am a huge fan and heavy user of SkyVector.  I think we would all benefit from a set of symbols for the METARs, not only to define the colors (green-VFR, blue-mvfr, etc.) but also the more subtle symbols (0, quarter, etc.) that sometimes appear within the color dot.  A logical place to put this would be at the bottom of the weather/layers window, perhaps even including a link to the formal definitions that define the boundary between VFR and MVFR. At the moment, the links I see provided in different forum reponses take me to a page on the AWC that I am not authorized to access-which isn't very helpful. 


One obligation of producing maps, whether on paper or electronically, is to provide a legend to the user knows what he or she is looking at.

Thanks for your consideration. This is a great site for the aviation community!  -Tom George

PS. If this info already exists somewhere on the site, please advise.  I dug around for quite a while without finding it.
