Minimum and maximum temperatures observed at specific times, consisting of up to a maximum of four temperatures (two maximum temperatures and two minimum temperatures).<br /></p><p><br /></p><p><font color="#ff0000">Due to Note 9 on Table A5-1: "consisting of up to a maximum of four temperatures (two maximum temperatures and two minimum temperatures)", there can be up to two temperature groups on each MeteorologicalAerodromeForecastRecord.  It is possible that Annex 3 instead specifies four temperatures for the entire TAF but no more than one for each Record, in which case this association would need to be corrected to be 0..1 and a constraint on TAF would need to be put in place to ensure that no more than two temperature forecast groups exist on any single TAF.</font><br /></p>
