Pre-Session Weather Forecast (API data from darksky.net)
Pre-Session Weather forecast showed that after initial cloud (71-78% cloud cover), clear skies would develop for most of
the night (16-30% cloud cover) with interval of cloud (41-59% cloud cover) around 02:00/03:00.
 No rain. Moderate wind (13-15 mph). with minimum temperature of 3degC by dawn.
Wind calm/light in first part of night, but strengthening later reached 17-19 mph by dawn.

In the event skies were clear all night, with light wind and minimum temperature of 1 degC.
