Mississippi starts the day wrapped in low clouds and haze, with damp air clinging to roads and windshields across central counties. Headlights glow softly through fog, and wet pavement sets the tone for cautious holiday travel this morning.
According to the National Weather Service in Jackson, patchy fog developed before sunrise with visibility reduced in spots. Temperatures sit in the mid-60s early, then surge into the upper 70s later today, continuing an unusual stretch of late-December warmth across central Mississippi.
That warmth keeps winter threats quiet for now, but it comes with tradeoffs. Fog may redevelop during the early morning hours, especially near rivers and low-lying roads. Drivers along I-20, I-55, and Highway 49 should plan for slower travel during peak morning hours. Use low beams and leave extra space.
Attention shifts to Sunday as rain chances rise. Clouds thicken, winds pick up, and showers move in by late day, becoming more widespread Sunday night. While rainfall amounts stay modest, wet roads could affect end-of-weekend travel. Gusts may approach 30 mph as cooler air pushes south.
Behind that system, temperatures fall sharply. Highs drop into the upper 40s Monday, then lows sink into the 20s by Monday night. That warm-to-cold transition raises concerns for slick spots if roads remain damp. Flash freezing becomes a possibility during early morning drives.
Looking toward New Year’s Eve on Wednesday, conditions appear dry but chilly, with lows near freezing. Travelers ringing in 2026 should prepare for cold air returning to the Deep South.
Plan ahead if driving Sunday or early next week. Keep jackets ready and watch bridges during colder mornings. Are you noticing fog or wet roads where you live today?
