Earliest Snowfall Dates Across 10 U.S. Cities
• A recent analysis highlights the earliest recorded snowfall dates in 10 major U.S. cities, spanning diverse climates and geographies. Denver holds the record for the earliest snow, which fell on September 3, 1961, while Charleston, South Carolina, experienced its record-early snow on December 11,
• These dates represent historical extremes rather than typical seasonal patterns. The study, based on data from AccuWeather, includes cities from the Rocky Mountains, Great Lakes, New England, Pacific Northwest, and Southeast coast. State-level records show that 19 states, including Colorado and Vermont, have experienced snow as early as September, while others, like New York and Illinois, have October records. Seattle's earliest snow occurred on October 27, 1971, despite Washington state's September record. These findings provide insight into the variability of early-season snowfall across the U.S.
Impact & Risks
Early-season snow can pose unique hazards, especially when it lands on warm ground, creating slushy and slippery conditions. Trees still holding leaves may bend under the weight of snow, potentially breaking branches and causing power outages. The National Weather Service advises caution during such events, emphasizing the importance of checking local forecasts and allowing extra time for travel. These risks are particularly relevant in areas unaccustomed to early snowfalls, where preparedness may be lower.
