Plot Description:Based on hourly METAR reports of temperature or dew point, this plot displays the longest periods above or below a given temperature threshold. There are plenty of caveats to this plot, including missing data periods that are ignored and data during the 1960s that only has reports every three hours. This plot also limits the number of lines drawn to 10, so if you hit the limit, please change the thresholds.
