Little Rock, Arkansas – A stretch of unseasonably mild weather may arrive across Arkansas this weekend, with new forecast guidance showing a strong possibility that temperatures could climb to 60 degrees or higher on the Winter Solstice, according to the National Weather Service.
Forecasters say the warming trend, expected to peak on Sunday, December 21, could bring temperatures well above typical late-December averages, especially across central and southern parts of the state.
What the National Weather Service Is Forecasting
The National Weather Service office in Little Rock released probabilistic temperature guidance Monday evening indicating a significant chance that much of Arkansas could reach or exceed the 60-degree mark on Sunday. These probabilities are highest across central and southern Arkansas, including the Little Rock metro area.
Meteorologists note that while not every location is guaranteed to hit 60 degrees, the overall signal for warmer-than-normal conditions is strengthening as the weekend approaches.
Areas Most Likely to Reach 60 Degrees
According to forecast guidance, central Arkansas has the greatest likelihood of seeing the warmest conditions. This includes:
- Little Rock and surrounding communities
- Portions of southern Arkansas
- Low-lying and urban areas that warm more efficiently
Northern Arkansas is also expected to experience milder weather than usual, though the probability of reaching 60 degrees decreases farther north, where highs may remain in the upper 50s.
How Unusual Is This for Late December?
Under normal conditions, December 21 brings much cooler daytime highs across the state. Average high temperatures typically range from:
- Upper 40s in northern Arkansas
- Low to mid-50s in southern Arkansas
A high near or above 60 degrees would represent a clear departure from seasonal norms, particularly for areas accustomed to winter jackets and heating demand during this time of year.
Why Temperatures Are Expected to Be So Mild
Meteorologists say the warm-up is tied to a broader weather pattern that favors the movement of mild air into the region. This pattern limits the intrusion of cold Arctic air and allows daytime temperatures to climb well above average.
At this time, the forecast does not indicate severe weather associated with the warm spell. Instead, the primary impact is expected to be milder afternoons and more spring-like conditions than residents typically experience on the Winter Solstice.
Potential Impacts on Daily Plans
While the warm weather may come as a welcome break from winter cold, officials say it could influence several aspects of daily life heading into the holiday week.
Travel and Outdoor Activities
Milder temperatures may benefit those planning holiday travel, outdoor shopping, or gatherings. Roads are expected to remain clear, and weather-related travel disruptions appear unlikely under the current forecast.
Energy Usage
Above-normal temperatures could temporarily reduce heating demand, especially during daytime hours. However, residents are advised to remain mindful that colder conditions may return later in the week.
Seasonal Awareness
Despite the warmth, forecasters caution that this is still winter. Rapid temperature swings are common in December, and colder air could move back into the region after the weekend.
Forecast Confidence and What Could Change
While confidence is growing that Sunday will be warmer than average, meteorologists emphasize that forecast probabilities can still shift as newer data becomes available. Cloud cover, wind direction, and the timing of weather systems could all influence final high temperatures.
Residents are encouraged to check updated forecasts later this week for more precise temperature expectations, especially if plans depend on outdoor conditions.
What Happens After the Weekend
Longer-range outlooks suggest that the warmth may be temporary. Cooler weather could return during the following week as weather patterns adjust. Forecasters will continue refining the outlook as the holiday period approaches.
Staying Informed
The National Weather Service will continue monitoring temperature trends and issuing updates as new forecast models are analyzed. Arkansans are encouraged to stay informed through official forecasts and local weather updates.
As winter officially begins, this brief warm spell serves as a reminder of how variable December weather can be across the region. Share your experiences in the comments below if you’ve noticed unusual winter warmth where you live.
