Sharp Temperature Drop Across Texas, Louisiana, Mississippi, Alabama, Georgia, Florida, and the Carolinas as EURO Model Shows Major Southern U.S. Cold Outbreak
Texas — A wide stretch of the South and Southeast, including Louisiana, Mississippi, Alabama, Georgia, Florida, and the Carolinas, is expected to experience a sharp temperature drop on Monday, December 15, according to the latest EURO Ensemble forecast. The model points to a strong and widespread cold outbreak, marking one of the most significant temperature swings of the month for the southern region.
EURO Model Highlights Strong Below-Normal Temperatures
The latest data shows a deep surge of cold air moving southward, with temperature anomalies significantly below average across multiple states. EURO maps display prominent blue and purple shading, indicating substantial cold intensity affecting areas from eastern Texas to the Carolina coastline.
Forecast guidance suggests that Mississippi, Alabama, Georgia, and the Carolinas may see the strongest temperature departures, though Texas, Louisiana, and northern Florida are also projected to fall sharply below normal.
Expected Impacts for Monday Morning Across the Region
As temperatures drop, residents across the region may encounter wind chills much lower than measured air temperatures, creating uncomfortable and potentially hazardous early-morning conditions. The cold surge could affect commutes, outdoor work, and sensitive infrastructure, with some areas cooling rapidly enough to trigger heating demand spikes.
Homes, vehicles, and outdoor surfaces may experience fast temperature declines, and while precipitation is not the primary concern, the sharp cold transition may still create disruptions for communities unprepared for such a dramatic shift.
Meteorological Setup Behind the Sudden Cold Surge
Meteorologists attribute the projected outbreak to a strong Arctic air mass descending through the central United States. A powerful upper-level trough is directing cold air southward, allowing the temperature drop to reach states that experienced relatively mild conditions earlier in the week.
The EURO model has shown consistent cold signatures across multiple runs, increasing confidence that a meaningful cold outbreak will occur. Although exact readings will vary from state to state, forecasters agree that below-normal temperatures are likely across a broad southern corridor.
What Residents Should Watch Going Forward
Residents should monitor updates from the National Weather Service regarding minimum temperatures, wind advisories, and frost or freeze potential. As Monday approaches, additional forecasts will clarify the exact timing and magnitude of the cold surge.
