Whether going as Pennywise or a princess, trick or treaters should plan to wear a warm costume this year.
October may end with a teeth-chattering 24 degrees on Halloween night in Chickasha. Halloween day is expected to be a brisk but not so frightful 45 degrees, according to the National Weather Service (NWS).
The days leading up to Halloween may be dark and stormy.
There is a 60% chance of rain on Tuesday afternoon and 80% chance of rain that night.
On Wednesday, the NWS predicts a 70% chance of rain. Wednesday evening may be dry but mostly cloudy. The evening temperature could mimic Halloween's at 25 degrees. A Halloween dress rehearsal is recommended.
