Old Man Winter is re-introducing himself to Fort Saskatchewan.
The big cool down is coming for Halloween.
"In the morning, it's probably going to start out rather pleasant," said Dan Kulak, meteorologist with Environment Canada. "By evening, it could be damp, a bit more wind picking up and temperatures will be dropping probably through afternoon and into the evening."
For trick-or-treaters, if they're starting at around 6:00 p.m., if should be around 4C with a 30 per cent chance of precipitation.
As the cold front moves through and drops the mercury, rain will change to snow. With the warm ground cooling off, slick driving conditions could be possible this week.
"Be careful of the falling temperatures and the weather, it's not too soon to get on the snow tires."
The cold weather is expected to stick around for at least two weeks.
