  2. Snowfall:
    Snowfall is relatively rare in Atlanta during December, averaging about 1 inch over a few days. Due to the city’s position in the southeastern United States, snow accumulation often melts quickly. In 2017, snow and ice storms resulted in significant disruption, but such events are infrequent.

  3. Seasonal Variability:
    Seasonal variability can lead to different precipitation patterns each year. Some winters experience more rain, while others may see colder conditions and occasional snow. A climate study from the University of Georgia highlighted that climate change may exacerbate this variability, suggesting increased unpredictability in precipitation events.

  4. Average Temperatures:
    Average temperatures in December range from 34°F at night to 55°F during the day. These temperatures influence the type of precipitation, with warmer instances causing rain and colder conditions potentially allowing for snowfall. According to the National Oceanic and Atmospheric Administration (NOAA), December experiences milder temperatures compared to January and February, which further supports the likelihood of rainfall.

What Is the Average Rainfall and Snowfall in December in Atlanta?

In December, Atlanta experiences an average rainfall of 4.4 inches and a minimal average snowfall of 2.3 inches. This data illustrates the precipitation patterns typical of the Southeastern United States during winter months.

According to the National Oceanic and Atmospheric Administration (NOAA), these average figures are derived from long-term climate records and reports. NOAA is a reputable organization that monitors weather, ocean, and atmospheric conditions.

Rainfall occurs more frequently than snowfall in Atlanta during December. The variation stems from seasonal changes and geographical factors, including humidity levels and temperature fluctuations. As the temperature hovers around 49°F to 57°F during the day, rain is more likely compared to snow, which requires colder conditions.

The Weather Channel further defines heavy snowfall as accumulations exceeding 6 inches, while light snow refers to minor accumulations. Snowfall in Atlanta is typically sporadic and can lead to various adverse effects on transportation and infrastructure due to infrequent snow-related preparedness.

Contributing factors to Atlanta’s precipitation include climate change, which affects weather patterns, urban heat islands that raise local temperatures, and prevailing winds that bring moist air from the Gulf of Mexico.

Data from NOAA indicates that Atlanta usually sees one or two snowfall events in December, with total accumulations varying yearly. This can complicate local emergency management strategies.

The impacts of average December precipitation include challenges for daily commuting, potential risks of ice accumulation, and implications for local ecosystems dependent on seasonal rainfall.

Beyond transportation, fluctuations in weather can influence public health, agriculture, and water supply. For instance, increased rainfall can lead to floods, disrupting communities.

Examples of these impacts include road accidents during rare snow events and the strain on local services to respond adequately.

To mitigate issues arising from precipitation, experts recommend improving infrastructure, such as drainage systems, and enhancing public awareness about severe weather protocols. Organizations like FEMA advocate for preparedness strategies.

Strategies to address precipitation effects include developing resilient urban planning, investing in real-time weather monitoring, and implementing green infrastructure, such as rain gardens, to manage runoff effectively.

What Severe Weather Risks Should You Be Aware of in December in Atlanta?

In December, Atlanta is subject to several severe weather risks, including winter storms and thunderstorms.

  1. Winter storms
  2. Ice storms
  3. Heavy rainfall
  4. Thunderstorms
  5. Flooding

Understanding these severe weather risks is crucial for preparedness and safety.

  1. Winter Storms: Winter storms in December can bring snow and frigid temperatures. The National Weather Service defines a winter storm as any combination of snow, sleet, and freezing rain that can disrupt daily life and create hazardous conditions. According to historical data, Atlanta receives about 2.8 inches of snow on average in December, with the potential for significant accumulation that can lead to travel disruptions and power outages.

  2. Ice Storms: Ice storms occur when freezing rain coats surfaces with ice. This makes roadways and sidewalks dangerously slick and can lead to the downing of power lines due to ice accumulation. The Atlanta Journal-Constitution reported that ice storms, even with minimal snowfall, have caused widespread power outages and dangerous driving conditions in past winters.

  3. Heavy Rainfall: December often sees increased rainfall, leading to the risk of urban flooding. According to the National Oceanic and Atmospheric Administration (NOAA), Atlanta receives approximately 4.3 inches of rain in December. This heavy rainfall can lead to flash flooding as the city’s drainage system struggles to handle the excess water, particularly in low-lying areas.

  4. Thunderstorms: Thunderstorms are also a risk in December. While they are less common than in the warmer months, they can occur when warm, moist air collides with colder air. These storms can produce strong winds, hail, and localized flooding. The Storm Prediction Center has noted that December thunderstorms in Atlanta, though infrequent, can be severe and lead to property damage.

  5. Flooding: The potential for flooding is particularly relevant during December due to a combination of heavy rainfall and waterlogged ground conditions from previous storms. The United States Geological Survey (USGS) emphasizes the importance of monitoring flood advisories, especially in areas adjacent to rivers and creeks, which can overflow rapidly during heavy precipitation.

Awareness of these risks will aid residents in better preparing for severe weather during December in Atlanta.

How Can Monthly Weather Patterns in December Influence Planning for Events in Atlanta?
