Chances are high this winter that dreams of a white Christmas will not become a reality in mid-Michigan. A strong El Niño climate pattern is expected to bring higher temperatures, less snowfall, and conditions that are warmer and drier than normal to the region.
What is Causing the Mild Winter Conditions?
El Niño events occur on a cycle every two to seven years and are identified by warmer-than-normal sea-surface temperatures over the central or eastern equatorial Pacific basin, coupled with changes to the atmosphere above known as the Southern Oscillation. Ryan Shadbolt, a Senior Academic Specialist in Michigan State University’s Department of Geography, Environment, and Spatial Sciences, pointed out that when equatorial easterly trade winds slacken, the typical upwelling of cold, deep water along South America’s western coast diminishes, which causes warm water to build up.
The National Oceanic and Atmospheric Administration’s Climate Prediction Center observed a 3-degree Celsius increase in sea-surface temperature. Data on subsurface temperatures show that this warmth is reaching deeper levels than usual, with anomalies going beyond +10.0 degrees Celsius.
How Strong is This El Niño and What Are the Historical Impacts?
Bob Dukesherer, a senior forecaster for the Grand Rapids National Weather Service branch, indicated that the United States faces a 70% probability of encountering the most powerful El Niño ever documented. Dukesherer noted that there have been about 10 strong or very strong El Niños dating back to 1950. They have all related to temperatures significantly above normal, snowfall being well below average, and precipitation either near or below normal,
he said.
Dukesherer stated that while there will still be cold snaps and periods of snow, the season will not feature what the area traditionally experiences during winter.
How Will the Weather Impact the Local Economy?
While some people may welcome the milder weather because it means less snow shoveling and lower heating bills, the conditions bring negative economic impacts for the state. A mild 2023-24 Michigan winter, which was another El Niño year, resulted in a $40 million loss for the state’s ski communities, where winter-based tourism and activities help drive the economy.
