South Bend, Indiana — Dense fog overnight could reduce visibility before showers and possible thunderstorms arrive early Friday.
According to the National Weather Service in Northern Indiana, fog is expected to redevelop overnight across portions of the region, with visibility potentially dropping to around one-quarter mile in some areas before sunrise Friday.
The reduced visibility could create hazardous travel conditions during the early morning hours, especially for drivers along major corridors including Interstate 80/90 through northern Indiana and Interstate 69 near Fort Wayne.
Forecasters say conditions will turn very warm and breezy on Friday, with temperatures expected to approach 70 degrees in some communities, which is well above typical early March averages.
As the atmosphere warms, showers and thunderstorms may begin developing near daybreak Friday, with rain chances ranging from 20% to 40% across northern Indiana through the morning hours.
While the overall risk of severe weather remains low, meteorologists say small hail could occur in some thunderstorms, and gusty winds may develop during the afternoon as breezy conditions increase.
Drivers traveling along Interstate 90, Interstate 80, and Interstate 69 could encounter changing conditions throughout the day, including fog early in the morning followed by scattered rain showers or thunderstorms.
Officials advise motorists to slow down in foggy areas, use low-beam headlights, and allow additional stopping distance when visibility drops.
The combination of fog, morning showers, and warmer temperatures could impact commuters and students traveling across northern Indiana as the workday begins Friday.
Residents are encouraged to monitor forecast updates overnight as conditions evolve heading into the morning commute.
