Well when it comes to forecasting weather here in WY the weatherman is more often wrong than right. Often times the most accurate forecast is, "we have weather, whether you like it or not." LOL So far though the weatherman seems to be right in that we are going to get snow as it is lightly snowing now. I just hope they are wrong about how much snow we are supposed to get. We have been lucky the past few years to not have snow on Halloween and our luck may be running out. We usually have to buy or make costumes that can fit over snowsuits and or winter jackets. One year when my kiddos were younger we not only had over a foot of snow on the ground, the temps were hovering just above zero degree with the wind chill factor. It was too cold to take the kids out to go door to door so the nursing homes and senior apts. got hit hard that year with TOTs.6 to 12 inches of Snow?
It sounds as if, you might want to change your Theme to an Abominable Snowman Haunt or a Scary Christmas Krampus theme?
Dealing with our RAIN in the Pacific Northwest is bad enough for the little Trick or Treaters, but having them and their parents slushing through SNOW, is just not right.
Hope the weatherman is wrong about your SNOW.
BUT.....when is the weatherman ever Wrong?
