More lake-effect snow will pound a number of communities located in the Upper Midwest and the Great Lakes through the week. Meanwhile, the major metropolitan areas of New York City, Philadelphia, and Washington, D.C. finally broke their snow drought with the latest blast of winter weather.

Here is what you need to know about the odds of winter weather this week in this part of the U.S.

Above Average January Snowfall Reported for Great Lakes and Beyond

The relentless cycle of lake-effect snow has already translated to above average snowfall amounts for the Upper Midwest and the Great Lakes. This pattern is forecast to linger throughout the Great Lakes through Thursday as high winds continue to whip up over the warmer waters of the lakes and create this distinctive type of snowfall.

The lake-effect snow is being fueled by the mass of Arctic air entrenched over the area along with windy conditions and warmer than average waters circulating in the Great Lakes. These forces have combined to produce higher than normal amounts of snowfall for the month of January thus far.

For example, the city of Grand Rapids, Michigan has recorded 26.5 inches of snow since the calendar flipped to 2024. The historical average for Grand Rapids over the entire month of January is 22.6 inches.

Snowfall has been measured in feet this month for cities located downwind of the lakes, including Buffalo, New York.
