VISIBILITY ITEM

Dear Windytv.
Thanks for your job. Such informations as "cloud base" and "humidity" are reliable and usefull for pilots, displayed in a very pleasant interface.
Nonetheless, "visibility" item seems to be completely unreliable.
We have mist in our area (LFSD 240230Z AUTO 03004KT 4000 BR NSC M07/M09 Q1025=), as the model forecast none in the main part of France.
Thanks to check that.
Cordialy,
