Cool, gray skies and a steady breeze greet the Crescent City this morning, with temperatures hovering near 47°F and clouds blanketing the lakefront. The damp chill across New Orleans feels every bit like December, but brighter skies and milder air are just ahead — a brief, comfortable stretch before next week’s colder air returns to much of the U.S.

According to the National Weather Service in New Orleans, skies will gradually clear through midday, pushing highs into the mid-50s. A light northeast wind keeps things crisp today, but by Wednesday, temperatures will rebound to the upper 60s, with plenty of sunshine expected through the end of the week. Friday could see highs near 70°F, making it one of the warmest days of December so far across southern Louisiana.

While the Gulf Coast remains mild, meteorologists are monitoring a larger Arctic system that will sweep across the Midwest and Great Lakes between December 11–17, potentially sending colder air south into the Deep South by next weekend. Long-range models hint that Louisiana could feel a dip in temperatures by early next week, though for now, the pattern stays dry and pleasant.

Residents are encouraged to take advantage of the calm stretch for outdoor decorating, errands, and travel — ideal late-fall conditions before winter’s next push.
