Snowfall above seasonal average

The NWS predicts that Indiana will experience snowfall above seasonal average during the winter season, with the heaviest snowfall occurring in the northern and central parts of the state. The NWS’s seasonal snowfall outlook for Indiana ranges from 20 to 28 inches, with some areas receiving even more. This is higher than the historical average snowfall of 22 inches for the state.

• Increased snowfall due to La Niña: La Niña is a climate pattern characterized by cooler than average sea surface temperatures in the central and eastern tropical Pacific Ocean. This pattern is associated with colder and wetter winters in the northern United States, including Indiana.
• Favorable weather patterns for snowfall: The NWS also predicts that Indiana will experience weather patterns that are favorable for snowfall during the winter season. These patterns include low-pressure systems tracking across the state and cold air masses moving in from the north.
• Potential for heavy snow events: The NWS warns that there is the potential for heavy snow events during the winter season, especially in the northern and central parts of the state. These events can lead to significant snowfall accumulations and hazardous travel conditions.
• Stay informed and prepared: Residents are advised to monitor the NWS forecast closely and be prepared for winter weather hazards, including heavy snowfall. Residents should have a winter emergency kit ready and be prepared to make changes to their travel plans if necessary.

Overall, the NWS predicts that Indiana will experience snowfall above seasonal average during the winter season. Residents should be prepared for hazardous driving conditions and power outages, and should take necessary precautions to stay safe.

Coldest periods in January and February

The NWS predicts that the coldest periods of the winter season in Indiana will occur in January and February. During these months, average temperatures are typically in the low 30s Fahrenheit, but the NWS forecasts that temperatures will frequently dip below freezing, especially at night and during the early morning hours.

• Stronger cold fronts: January and February are typically the months when the strongest cold fronts move through Indiana. These cold fronts bring with them cold air masses from the north, causing temperatures to drop significantly.
• Less sunshine: January and February also receive less sunshine than other months of the year. This lack of sunshine means that the ground and air have less opportunity to warm up during the day, leading to colder nighttime temperatures.
• Increased snow cover: Snow cover can also contribute to colder temperatures. When snow covers the ground, it reflects sunlight back into the atmosphere, preventing the ground from absorbing heat. This can lead to even colder temperatures, especially at night.
• Wind chill: Wind chill is a measure of how cold the air feels on exposed skin. When the wind blows, it can remove the warm layer of air that surrounds the body, making the air feel colder. Wind chill can be a significant factor in Indiana during January and February, when strong winds are common.

Overall, the NWS predicts that January and February will be the coldest months of the winter season in Indiana. Residents should be prepared for extended periods of cold weather and should take precautions to stay warm.

Heaviest snowfall in northern and central Indiana

The NWS predicts that the heaviest snowfall during the winter season in Indiana will occur in the northern and central parts of the state. These areas are more likely to experience snowstorms and lake-effect snow, which can lead to significant snowfall accumulations.

• Proximity to the Great Lakes: The northern and central parts of Indiana are located near the Great Lakes, which can have a significant impact on snowfall. When cold air moves across the relatively warm waters of the Great Lakes, it picks up moisture. This moisture can then condense and fall as snow when the air reaches land.
• Lake-effect snow: Lake-effect snow is a type of snow that forms when cold air moves across a warmer body of water. As the air moves over the water, it picks up moisture and heat. When this air reaches land, it rises and cools, causing the moisture to condense and fall as snow. The northern and central parts of Indiana are particularly susceptible to lake-effect snow because of their proximity to the Great Lakes.
• Snowbelts: Snowbelts are areas that are known for receiving heavy snowfall. In Indiana, the snowbelts are located in the northern and central parts of the state. These areas are typically located downwind of the Great Lakes and are more likely to experience lake-effect snow.
• Elevation: The northern and central parts of Indiana are also generally higher in elevation than the southern part of the state. Higher elevation areas are typically colder and more likely to receive snow.

Overall, the NWS predicts that the northern and central parts of Indiana will experience the heaviest snowfall during the winter season. Residents in these areas should be prepared for hazardous driving conditions and power outages, and should take necessary precautions to stay safe.

La Niña pattern contributing to cold and wet conditions

La Niña is a climate pattern characterized by cooler than average sea surface temperatures in the central and eastern tropical Pacific Ocean. This pattern is associated with colder and wetter winters in the northern United States, including Indiana.

During a La Niña winter, the jet stream, which is a high-altitude wind current that steers weather systems, is typically positioned farther south than normal. This southward shift in the jet stream allows cold air from the Arctic to penetrate deeper into the United States, leading to colder temperatures.

In addition, La Niña winters are often associated with increased precipitation in the northern United States. This is because the cooler sea surface temperatures in the Pacific Ocean can lead to changes in atmospheric circulation patterns, which can favor the development of storms that track across the United States.

The NWS predicts that a La Niña pattern will be present during the winter of 2024-2025. This means that Indiana is likely to experience colder and wetter conditions than normal during the winter season.

Residents should be prepared for extended periods of cold weather and should take precautions to stay warm. Residents should also be aware of the potential for increased precipitation and should be prepared for hazardous driving conditions and power outages.

Negative Arctic Oscillation (AO) pattern favoring colder temperatures and increased snowfall

The Arctic Oscillation (AO) is a climate pattern that describes the variation in atmospheric pressure between the Arctic and the mid-latitudes. A positive AO pattern is associated with higher pressure in the Arctic and lower pressure in the mid-latitudes, while a negative AO pattern is associated with lower pressure in the Arctic and higher pressure in the mid-latitudes.

During a negative AO pattern, the jet stream is typically positioned farther north than normal. This northward shift in the jet stream allows cold air from the Arctic to penetrate deeper into the United States, leading to colder temperatures.

In addition, a negative AO pattern can also lead to increased snowfall in the northern United States, including Indiana. This is because the northward shift in the jet stream can favor the development of storms that track across the northern United States.

The NWS predicts that a negative AO pattern will be present during the winter of 2024-2025. This means that Indiana is likely to experience colder temperatures and increased snowfall than normal during the winter season.

Residents should be prepared for extended periods of cold weather and should take precautions to stay warm. Residents should also be aware of the potential for increased snowfall and should be prepared for hazardous driving conditions and power outages.
