La Niña Weakens, But Still Promises Snowy Indiana Winter

Federal forecasters are tracking a weak La Niña phenomenon that is expected to influence Indiana's winter weather. Despite its diminished strength, La Niña is predicted to persist through January, with a 54% chance of continuing through February before transitioning to neutral conditions. This ongoing pattern suggests that residents of Indiana may experience a winter with higher-than-average precipitation and snowfall.

The National Weather Service's Climate Prediction Center notes that below-average ocean temperatures in the Pacific Ocean, combined with specific wind patterns, are consistent with La Niña. Historically, these conditions have led to increased storm activity tracking towards the Great Lakes region, impacting areas like Indiana. While previous La Niña events have correlated with wetter winters in the state, predicting temperature effects has been more challenging.

For Indianapolis specifically, meteorologists anticipate temperatures to average near or colder than normal this winter. The city is also projected to receive slightly more than the typical 25 inches of snowfall. Precipitation levels are expected to be near to slightly above normal, with December showing a greater potential for wintry precipitation in its first half.
