Here's something that crossed my mind, by the way, it's really rather cold in Florida, usually so. Perhaps SpaceX is taking an opportunity to conduct prop loading tests in "unique" conditions?https://twitter.com/julia_bergeron/status/948902273861767170 …
If the Zenit rocket saw this, it must be thinking "LOLOLOL what a weak rocket! You know I can launch in -30 C (*) with sub-cooled kerosene and fly when snowing! 
"
(*) I have checked the Baikonur Zenit User Manual and yes it was stated it can launch at -30 - +45 C.
