Indianapolis, IN – Central Indiana faces a dramatic weather change Tuesday, October 13, through Friday, October 16, as potentially record breaking 90 degree heat gives way to several rounds of rainfall, with isolated flooding possible in areas receiving the heaviest downpours.
According to the National Weather Service in Indianapolis, the city could break another daily high temperature record Tuesday after already setting a record Monday. Tuesday's forecast high is 90 degrees, exceeding the existing October 13 record of 86 degrees set in 1975.
If Indianapolis reaches 90 degrees, it would also mark the latest 90 degree day ever recorded in the city.
Heavy Rain Arrives Wednesday
The unusually warm conditions will give way to increasing rain chances late Tuesday night into Wednesday, October 14.
Forecasters expect periods of locally heavy rainfall, with the greatest precipitation likely Wednesday morning into the afternoon.
Most central Indiana communities are forecast to receive between 0.5 and 1 inch of rainfall through Thursday, October 15. However, localized totals could reach 2 inches.
Communities around Indianapolis, including Carmel, Noblesville, Greenwood, Bloomington, Lafayette and surrounding areas, could experience periods of wet weather.
Occasional thunderstorms are also likely, although the Weather Service currently indicates a low end threat for severe weather and flooding.
Wednesday Travel Could Be Affected
The timing of the heaviest rainfall could create difficult driving conditions during Wednesday's morning commute and early afternoon.
Drivers along Interstate 65, Interstate 69, Interstate 70 and Interstate 465 should prepare for wet pavement, reduced visibility and possible standing water in poorly drained areas.
Rain chances are expected to continue periodically through Friday, October 16, although the heaviest rainfall is currently forecast for Wednesday.
Despite the potential for localized flooding, widespread flooding is not currently indicated in the National Weather Service outlook.
Residents should monitor updated forecasts as rainfall timing and amounts become clearer, particularly in locations prone to collecting water during heavy downpours.
