One of the most upvoted requests from players prior to SU7 was to have Live Weather more closely match the conditions stated in METARs. The dev team responded to that very popular request by introducing a new METAR-based weather injection system in the vicinity of airports where METAR data is available. Unfortunately, this introduced a new issue where there is now a sudden and abrupt transition between the two weather injection models rather than it occurring smoothly and looking natural. The devs are continuing to make further refinements and improvements to Live Weather in future Sim Updates based on player feedback.
