March weather can be … unpredictable.
As winter loosens its grip on North Georgia, we will have to brace ourselves for the kitchen sink, which is usually what Mother Nature throws us. We all know temperatures can swing dramatically and spring storms can, and do, wreak havoc.
March arrives in North Georgia like an indecisive guest, bringing equal parts promise and unpredictability to the foothills and mountains that define this scenic corner of the state. While the month signals the official arrival of spring, veteran residents know better than to pack away their winter coats just yet. One example was the Blizzard of the Century, the biggest winter storm of modern times. It was an incredible thing to forecast. No one believed me when l was forecasting 20-30 inches of snow.
The transitional nature of March weather creates a unique atmospheric battleground across North Georgia. Cold air masses from the north collide with warm, moisture-laden systems pushing up from the Gulf of Mexico, producing a weather pattern that meteorologists describe as volatile and difficult to predict more than a few days in advance. They are basically “weather wars.” The worst March tornado outbreak in Georgia history was the March 2007 outbreak, with 2008 being the second worst.
March 2007 outbreak
In March 2007, 21 tornadoes touched down in eastern, middle and southern Georgia, leaving nine people dead, nearly 100 injured, and hundreds of millions of dollars in damage. The most devastating tornado was a violent EF-3 tornado with winds of up to 165 mph that was a mile wide and cut a 38-mile path through Webster, Sumter and Macon counties, directly striking the 143-bed Sumter Regional Hospital in Americus.
March 2008 Atlanta outbreak
The second major March outbreak was in March 2008, which struck metro Atlanta on March 14-15. In total, 45 tornadoes were confirmed over the 24-hour period from eastern Alabama to the Carolina coast, causing half a billion dollars in damage. An EF2 tornado struck downtown Atlanta, damaging the CNN Center, Georgia Dome, and Georgia World Congress Center. I remember that night like it was yesterday.
Average temperatures during March typically range from the mid-30s during nighttime hours to the upper 50s and low 60s during the day. However, these averages mask the true character of the month. It’s not uncommon for us to experience a 70-degree afternoon followed by a freeze warning just 48 hours later.
Precipitation becomes a dominant feature of the March landscape. The month typically delivers between five and six inches of rainfall across most of the region, with higher elevations in the Blue Ridge Mountains occasionally seeing more. This moisture is critical for replenishing reservoirs like Lake Lanier and Lake Allatoona, which serve millions of residents in the greater Atlanta metropolitan area.
The rainfall pattern in March tends to shift from the steady, soaking rains of winter to more dynamic spring systems. Thunderstorms become increasingly common as the month progresses, and while severe weather is less frequent than in April or May, March can still produce damaging winds, hail, and isolated tornadoes, particularly in the lower elevations of north Georgia.
For those living in the highest elevations, snow remains a possibility throughout March. Towns like Helen and Hiawassee, sitting at elevations above 1,500 feet, can experience late-season snow events that occasionally disrupt travel and close schools. The 2018 March snowstorm remains fresh in many memories, when over a foot of snow blanketed portions of the north Georgia mountains, creating treacherous conditions and knocking out power to thousands.
The warming trend becomes more pronounced as March draws to a close. By the final week of the month, high temperatures regularly push into the 60s and occasionally touch 70 degrees, while overnight lows moderate into the 40s. This warming triggers one of North Georgia’s most celebrated natural phenomena: the spring bloom.
Cherry blossoms, dogwoods, and redbuds begin to paint the landscape in delicate shades of pink and white. Wildflowers carpet the forest floor, and the verdant green of new growth transforms the brown winter hillsides into a patchwork of emerging life. For nature enthusiasts and photographers, late March offers some of the year’s most stunning vistas.
Yet this beauty comes with caution. The temperature fluctuations can devastate early bloomers if a hard freeze follows a warm spell. Fruit farmers in the area watch forecasts anxiously, knowing that a single night of subfreezing temperatures can destroy blueberry, apple, and peach crops that showed promise just days earlier.
For outdoor enthusiasts, March presents both opportunities and challenges. The Appalachian Trail, which winds through north Georgia’s Chattahoochee National Forest, sees increased foot traffic as thru-hikers begin their journey northward toward Maine. However, muddy conditions from frequent rain and unpredictable temperature swings require proper preparation and flexibility.
As climate patterns continue to evolve, meteorologists note subtle shifts in March weather trends. Recent years have shown a tendency toward greater temperature extremes and more intense precipitation events, though whether this represents a long-term pattern or natural variability remains under study.
For North Georgians, March remains a month of anticipation and adaptation. It’s a time when the promise of spring hangs tantalizingly close, yet winter occasionally reasserts itself with unexpected vigor. Residents have learned to dress in layers, keep umbrellas handy, and maintain a healthy respect for the region’s atmospheric mood swings. As the old mountain saying goes: “If you don’t like March weather in north Georgia, wait 15 minutes – it’ll change.”
