You will have to add some layers to your Halloween costume tonight.
The forecast is calling for some snow and colder temperatures.
Meteorologist Michael Carter from the Weather Network says as the night goes on it'll just get worse.
"After the sun goes down you will see the temperatures slipping even a bit further. So in the case of Hallow'en this year, the sunset is going to be right around 5:56 PM. So once the sun goes down, if you are Trick or Treating expect those temperatures to begin to drop relatively quickly."
Carter notes we can also expect another storm system tomorrow as well.
