Indianapolis is set to experience a dramatic temperature swing this weekend, with Saturday's chilly 43°F morning giving way to a high near 68°F under sunny skies.

Why it matters

The rapid temperature shift from frost to flip-flop weather is a stark reminder of the unpredictable nature of spring in the Midwest, where dramatic swings between winter and summer conditions are common. This weekend's warmup will provide a welcome respite for residents after a chilly start to the month, but also raises concerns about the potential for severe storms later in the week.
