US EditionGreat Lakes Region Preparing for Bad Weather as Lake-Effect Snowfall Ingredients Begin Mixing
Lake effect snow forms when cold air passes over warmer Great Lakes waters, producing narrow bands with snowfall rates of 1 to 2 inches per hour, causing rapid, localized snow accumulation.
- Wednesday, snow began falling in and around Houghton, Michigan, and a blizzard warning covers the Keweenaw Peninsula through Thursday morning.
- Meteorologists explain that lake-effect snow forms when cold, dry air blows over warmer Great Lakes water in the 40s, picking up heat and moisture before rising to form snow.
- Forecasters note intense hourly rates when bands persist, as narrow snow bands often only 5 miles wide, causing neighborhood variability with snowfall rates of 1 to 2 inches per hour and up to 2 to 3 inches.
- Forecasters warn that south of Buffalo, New York could see a foot to 18-inches of snow, while 6 to 10 inches may fall near Watertown, amid western New York lake-effect snow warning.
- By the mid-20th century, radar and forecasting tools helped clarify the phenomenon first noticed in the late 1800s, as Tug Hill Plateau, Syracuse, Erie, and Buffalo saw heavy snow totals.
