The flakes weren't big at all, this size of snowflake in England wouldn't make an impression as it would melt as soon as it reached the ground, but here it sticks. Fast.
When it is snowing, or has freshly snowed, it's really light at night. I guess the street lights etc reflect off the sparkling white snow. The bedroom is cast with an orange glow - when this first occurred we thought there must be an event on nearby, requiring lots of big lights,; but no, it was just the snow.
