Northern Indiana is in for a stretch of hot and humid weather through Sunday, followed by a strong chance of thunderstorms on Monday. The National Weather Service has warned that some of these storms could be severe, especially during the late afternoon and evening hours.
Sunday Weather: Hot and Slightly Unstable
On Sunday, temperatures in cities like Fort Wayne, South Bend, and Warsaw will rise into the upper 80s to low 90s (around 31–33°C). There is a low chance, about 15–20%, of a pop-up thunderstorm, but most areas will remain dry. The humidity will make it feel even warmer, so staying hydrated and limiting outdoor activity is advised.
Monday: High Storm Risk with Strong Winds and Heavy Rain
By Monday, conditions become more unsettled. A weather system is expected to move through the region, bringing a 70–90% chance of thunderstorms from late afternoon into the evening. These storms could bring heavy rainfall, strong gusty winds, and frequent lightning—particularly along U.S. Route 30 and the I-69 corridor.
Travel during the Monday evening commute may be affected. Drivers should be cautious due to reduced visibility, wet roads, and the possibility of traffic delays.
Safety Advice for Residents
Residents in northern Indiana should prepare in advance. Secure loose outdoor objects like furniture or umbrellas, charge mobile phones in case of power cuts, and avoid unnecessary travel during stormy periods.
Tuesday and Beyond: Sunshine Returns
The good news is that the weather will improve by Tuesday. The skies will clear, and temperatures will settle into the low 80s (around 27°C) with lower humidity. This dry and pleasant pattern is expected to continue through midweek, offering relief from the earlier stormy and humid conditions.
Northern Indiana is set to experience hot, sticky weather on Sunday, followed by potentially severe storms on Monday. Residents should stay weather-aware, especially during the Monday evening commute. After that, a break in the weather brings sunshine and milder temperatures from Tuesday onwards.
