Aerosol spraying: Days prior to blizzard

Here are aerosols that were sprayed in the West (BC) and picked up moisture as they headed into Alberta. Aerosols are used to intensify a weather front and possible re-direction through the use of electrically-charged lithium/metallic particulates ejected by the spraying aircraft. Before the storm (blizzard) hit us with snow, I can recall our weather being in the high 10s.
