What weather pattern is common during the fall months around Lake Ontario?

During the fall months, Lake Ontario is known for a weather pattern called lake-effect snow. This phenomenon occurs when cold air moves over the relatively warmer waters of the lake. The warmth from the water causes the air to pick up moisture and, as it moves inland and cools, the moisture is released in the form of snow. This effect is particularly pronounced in late fall and winter, but it often begins to emerge in the later weeks of autumn as temperatures start to drop.

Lake-effect snow can lead to significant snowfall accumulation in areas downwind of the lake, which are often located in the snowbelt regions. It is important for residents and those traveling around Lake Ontario to be aware of this weather pattern, as it can create hazardous driving conditions and impact outdoor activities. Understanding lake-effect snow is essential for navigating the local climate effectively during this time of year.
