A sudden thunderstorm by 8 p.m. increased the humidity above 90% and dropped the temperature, which reached the dew point, triggering a peak of LC to 70 mA. By 9 p.m., the thunderstorm had changed to light rain, keeping the LC at 20 mA. By 6 a.m., at dawn, the temperature rose, the humidity dropped, and the leakage current decreased to 15 mA.
