Historic Gulf Coast Snowstorm - January 2025

I. Historic Gulf Coast Snowstorm:

• Unprecedented Snowfall: The Gulf Coast experienced a rare and record-breaking snowstorm, with some areas seeing the heaviest snowfall in over a century. Several locations broke all-time records.
• Quotes:“Historic, city-snarling snowfall – in some cases, possibly the heaviest in more than a century – was spreading on Tuesday into coastal communities from Texas toward Florida.”
• "The Great Southern Snowstorm of 2025 is one of the most impactful winter storms in history for the Gulf Coast, obliterating Florida’s all-time state snowfall mark and smashing local accumulation records from middle Louisiana to western Florida."
• Record Snow Totals: Multiple cities experienced record snowfall, with amounts far exceeding forecasts.
• Examples:Pensacola, FL: 8.9 inches (all-time record, more than double the previous state record). The city of Milton, just northeast, recorded 9.8 inches, which is pending confirmation as the new state record.
• New Orleans, LA: 8 inches at the airport, breaking the previous record of 2.7 inches, with some areas reporting up to 11.5 inches.
• Mobile, AL: 7.5 inches (all-time record).
• Baton Rouge, LA: 6-8 inches (heaviest since 1895).
• Quote: ““It’s an incredible, incredible event,” said Michael Mugrage, a meteorologist at the National Weather Service office in Mobile, Alabama, where many of the highest snowfall totals from the region were reported. “It puts it in perspective how rare this is.”
• Key Factors:Polar Vortex: A strong polar vortex stretched unusually far south, bringing extremely cold air from the Arctic to the Gulf Coast.
• Upper Level Disturbance: An upper-level disturbance moving south from Canada helped generate lift, leading to precipitation.
• Dry Air: Surprisingly, very dry air aloft helped the formation of snow, as it caused saturation to occur at below-freezing temperatures.
• Warm Gulf Waters: Unusually warm Gulf waters may have provided a higher-than-expected source of moisture, contributing to increased precipitation amounts, but also a chaotic mix of snow, sleet, and freezing rain in some areas.
• Impacts:Travel Disruption: Roads were closed, including stretches of I-10 in Florida.
• Quote: “The storm system that brought so much snow also sank thermometers into record-breaking territory across the Deep South.”
• Record Low Temperatures: The storm also brought record low temperatures to cities in the region, with some locations experiencing the coldest temperatures since the late 19th century.
• Recreational Activity: Locals were seen using make-shift sleds to enjoy the rare snow.
• Rarity:The conditions that led to this storm are exceptionally rare in the Gulf Coast region. The chance of a similar event occurring in any given winter is estimated to be around 1%. The event is comparable to the historic storm of 1895.
• Quote: “With 2025 rivaling only 1895 for the historical high snowdrift on the Gulf Coast, this general kind of event might only have around a 1% of occurring in any given winter."
• Comparison to Historical Events: While there have been instances of snow in Florida in the past (documented as far back as the 1700s), this event was far more significant and widespread.
