A Powerful Lake Effect Snow causing storm

A powerful winter storm, fueled by the Great Lakes, has brought significant snowfall and hazardous conditions to parts of the United States. Lake-effect snow, a meteorological phenomenon where cold air moves across warm lake waters, has led to heavy snowfall accumulations in specific regions.

What is Lake Effect Snow? (NWS Says)

Lake effect snow is common across the Great Lakes region during the late fall and winter. Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. The air rises, clouds form and grow into narrow band that produces 2 to 3 inches of snow per hour or more.

Wind direction is a key component in determining which areas will receive lake effect snow. Heavy snow may be falling in one location, while the sun may be shining just a mile or two away in either direction. The physical geography of the land and water is also important. National Weather Service meteorologists consider these factors as well as others when forecasting lake effect snow.

Impactful Snowfall

Areas around the Great Lakes, particularly in New York and Michigan, have been particularly hard-hit. Some regions have reported snowfall totals exceeding several feet, causing significant disruptions to travel and daily life.

Challenges and Precautions

• Travel Disruptions: Heavy snowfall and icy road conditions have led to widespread travel disruptions, including flight cancellations and highway closures.
• Power Outages: Strong winds and heavy snow can cause power outages, leaving many residents without electricity.
• Emergency Services: Emergency services are working tirelessly to respond to calls and assist those affected by the storm.

Safety Tips

• Stay Indoors: If possible, stay indoors and avoid unnecessary travel.
• Dress Warmly: Wear warm clothing, including hats, gloves, and scarves.
• Check on Neighbors: Check on elderly neighbors and those who may need assistance.
• Prepare for Power Outages: Have flashlights, batteries, and other emergency supplies ready.

As the storm continues to impact the region, it’s crucial to stay informed about the latest weather updates and follow the advice of local authorities.

What National Weather Service Says:

The Arctic Outbreak: Heavy Lake Effect Snow in the Great Lakes Region

As per National Weather Service An Arctic outbreak of cold air will expand south and east from the northern Plains through the Midwest and persist into next week. Dangerously cold wind chills are expected in the Northern Plains and Upper Midwest. Heavy lake-effect snow bands and snow showers have developed downwind of the Great Lakes, and will continue into next week. Travel could be very difficult to impossible.
