Forecast

Alpena's weather is affected by its location near Lake Huron, which helps regulate air pressure. Warm air from the lake rises, creating low pressure, and cool air from Canada sinks, creating high pressure.

The surrounding hills and woods in Alpena also impact air pressure. As winds blow in from the lake, they are forced upwards, creating areas of low pressure near the hills.

In the winter, cold Arctic air dominates, bringing high pressure and cold temperatures. In the summer, warm air from the lake brings low pressure and warmer temperatures.

Alpena has a humid continental climate, characterized by large seasonal pressure changes. This means it experiences cold winters and warm summers, with pressure fluctuations affecting the weather patterns.
