La Porte, Indiana – Lake effect snow is expected to increase across northwest Indiana tonight into Saturday, with localized accumulations and dangerous cold conditions prompting travel and safety concerns through the weekend.
According to the National Weather Service in Northern Indiana, light lake effect snow today will become more focused and intense over northwest Indiana tonight. The highest confidence for accumulating snow is in La Porte County, where 2 to 4 inches of snow are possible by Saturday. Areas farther west, closer to Lake Michigan, could see even higher localized totals where snow bands persist.
Snow showers are expected to continue west of U.S. Route 31 tonight through Saturday before gradually tapering off Saturday night. Snowfall rates may vary significantly over short distances, a common characteristic of lake effect events, leading to rapidly changing road conditions.
Major travel routes including Interstate 94, Interstate 90 (Indiana Toll Road), Interstate 80, U.S. Highway 20, and U.S. Highway 30 may be impacted by slick roads and reduced visibility, especially when heavier snow bands move through. Drivers are urged to slow down and remain alert for sudden drops in visibility.
In addition to snowfall, bitter cold air will remain in place. Overnight low temperatures are expected to fall below zero in spots, with morning wind chills dropping below zero both Saturday and Sunday. These conditions increase the risk of frostbite for anyone spending extended time outdoors.
The National Weather Service advises residents to dress in layers, limit outdoor exposure, and bring pets indoors. Motorists should keep winter emergency supplies in vehicles, especially when traveling near the lakeshore where conditions can deteriorate quickly.
Looking ahead, lake effect snow is expected to diminish by early Sunday, though cold temperatures will persist. Students, weekend travelers, and early-morning workers across northwest Indiana should continue monitoring forecast updates, as small shifts in wind direction could significantly change snowfall totals.
