A significant winter storm remains on track to impact Indiana late Sunday through Monday, bringing a mix of heavy snow, freezing rain, and dangerous travel conditions. Here is our current thinking. A powerful weather system will move from the Oregon coast to the Texas Panhandle by Sunday, pulling in moisture from the Gulf of Mexico and the Atlantic Ocean. As the system moves through the Midwest, it’s expected to bring snow to central Indiana Sunday evening, with cold air from an Arctic high-pressure system keeping temperatures low enough for widespread snowfall. As the system evolves, warm air aloft may intrude, creating a band of mixed precipitation or freezing rain south of I-70. Areas farther north are likely to remain primarily snow, with the potential for moderate to heavy accumulation. But the exact track is still uncertain - changes will be made. Current Thinking: *Timing: Snow begins late Sunday and intensifies overnight, continuing into Monday. Lingering snow showers may persist into Tuesday. *Precipitation Types: Central and Southern Indiana: Snow transitioning to a wintry mix or freezing rain, especially south of I-70. Northern Indiana: Predominantly snow, with potential for heavier accumulation. *Snowfall Potential: Accumulations exceeding six inches are possible, with localized higher amounts. Exact totals depend on the storm’s track, which remains uncertain. *Ice Potential: Freezing rain could cause significant ice accumulations in southern Indiana, creating hazardous conditions. *Cold Air: Arctic air following the system will drop temperatures into the teens and single digits, with subzero wind chills. We have high confidence that the very cold air will settle into the entire state of Indiana. Key Uncertainties The path of the storm and how much warm air moves in will decide the type and amount of precipitation. A stronger storm could bring heavier snow and a mix of wintry weather farther north, while colder Arctic air could push the storm’s path farther south. Preparations *Monitor updates as confidence in the storm's specifics grows. *Prepare for potential travel disruptions and power outages. *Avoid relying on early snowfall totals from weather apps, as these are raw model data and not forecasts. A sample of the raw model data is in the attached image. Stay tuned for detailed updates throughout the week. A lot can, and most likely will change between now and Sunday.
