Indiana – A sharp wind cuts across open fields and pushes temperatures down, setting up a quick freeze risk after sunset. Drivers around Fort Wayne will notice dry roads turning slick in patches as temperatures fall toward 26°F and leftover moisture refreezes.

According to the National Weather Service, northwest winds will gust up to 30 mph through the day, with a high near 49°F before a rapid evening cooldown. Skies clear tonight, allowing temperatures to drop quickly, increasing the chance for isolated icy spots on bridges and overpasses across Allen County .

Tuesday brings sunshine but keeps a chill in place. Highs stay near 43°F with lighter winds, helping stabilize road conditions after the early freeze risk. By Tuesday night, calmer air and clear skies push lows back near 29°F.

A noticeable shift arrives Wednesday as temperatures climb to 61°F under partly sunny skies. South winds return and begin a steady warming trend that accelerates into Thursday.

By Thursday afternoon, highs reach near 70°F with a slight chance of showers developing after 2 p.m. Conditions turn more active Thursday night, with a 50% chance of showers and possible thunderstorms that could dampen roads along I-69 and I-469.
