Buffalo is bracing for a significant cold snap, with temperatures expected to plummet dramatically over the weekend. Local meteorological reports predict a sharp decline, with lows reaching 15°F (-9°C) and highs struggling to surpass 25°F (-4°C). Snowfall is also anticipated, with potential accumulations of up to 6 inches in some areas. The cold front, originating from Canada, is bringing frigid air and the possibility of lake-effect snow, which could exacerbate conditions in the city and surrounding regions. Lake-effect snow occurs when cold air passes over the warmer waters of Lake Erie, picking up moisture and depositing it as snow on the leeward side, often leading to intense, localized snowfall.
