Trick-or-treaters might consider a costume that incorporates an umbrella, as a rainy Halloween has been forecast for the Tri-Cities area.
Expect warm, but soggy, conditions as the National Weather Service forecast calls for a high near 65, as well as rain. At least the chance for severe weather is low, though weather officials warn that parents and youths shouldn't ignore threats of lightning.
Elburn-based weather observer Brad Hruza notes that "there is a 100 percent chance of rain," but also "a few rumbles of thunder." He said that "parents should definitely keep an eye on the weather, as lightning may be in the area."
Richard Castro, a meteorologist with the National Weather Service, said the best chance of severe weather will be off to the south, and that most of Kane County has a 5 percent probability for severe weather.
Castro said rain during trick-or-treating hours is possible, and it could be heavy at times. There is concern that parents and youths eager to celebrate might be tempted to go out even if there are dangerous conditions.
"I know a lot of people want to take their kids out trick-or-treating when they get home from work," Castro said. "Rain is one thing, but if there are lightning-producing storms, it could be hazardous."
Castro suggested following procedures observed by swimming facilities and let a significant amount of time pass after lightning is sighted before resuming outdoor activities.
"Any lightning is hazardous," he said.
