The visibility chart shown below was generated with METARs Downloader set to limit visibility reports at 10SM or 16.09KM during chart generation so that the chart will better display lower visibility reports. [The National Weather Service generally calls 10SM/16.09KM unlimited visibility.] Mount Washington (KMWN) reports much higher numbers than is required in the METAR specification. The actual numbers may be found in the table following the chart, the weather log below, and in the decoded data graphic above..
