Halloween begins in Columbus overcast at 50°F early Saturday, with mostly cloudy skies forecast for the day. The afternoon should reach about 66, with a 30% chance of rain. Costumes are unlikely to need rain protection; a light jacket may be useful after sunset.
A Mostly Cloudy, Mild Halloween
Saturday, October 31, will remain mostly cloudy. Temperatures should climb through the 50s around midday and reach the mid-60s during the afternoon before settling to a cloudy low near 53 Saturday night.
What a 30% Chance of Rain Means
A 30% precipitation probability does not mean rain will fall for 30% of the day or across 30% of Columbus. According to the National Weather Service Louisville, it means there is a 30% chance that at least 0.01 inch of rain will fall at a specific forecast point during the stated period.
Sunday brings a warmer afternoon, with partly sunny skies and a high near 72. There is a small chance of a passing shower Sunday into Sunday night, but most of the day should remain dry for outdoor plans.
Rain Chances Increase Midweek
A slight chance of rain showers arrives Monday, with mostly cloudy skies and a high near 67. Tuesday looks warmer and partly sunny, with temperatures reaching about 75 before rain chances rise Tuesday night, according to National Weather Service.
The National Weather Service forecast currently points to Wednesday as the wettest day of the week, with showers likely and a 60% chance of precipitation. Additional shower chances may continue Thursday into Friday.
