Louisiana Forecast Swings From Warm to Chilly
Southeast Louisiana temperatures rise to the 80s Thursday before a stronger cold front brings a chill by Sunday morning.
Updated on Nov. 5, 2026 in Forecasts
Southeast Louisiana is forecast to reach 80 to 86 degrees Thursday afternoon under plenty of sunshine and less humidity. A weak cold front moves through Friday, followed by a stronger one that brings a chill by Sunday morning.
Why it matters
The sharp temperature swing over the weekend will change conditions quickly for residents and visitors in New Orleans and surrounding areas. Cooler morning temperatures will contrast with warmer afternoons throughout the period.
Forecast figures show Northshore Friday morning lows of 46 to 48 degrees against Southshore lows of 59 to 62 degrees, a gap of roughly 13 degrees across Lake Pontchartrain. The forecast does not indicate how long the Friday shower chance near the coast will persist.
The details
Thursday brings plenty of sunshine, light winds, and reduced humidity on both sides of Lake Pontchartrain. A weak cold front on Friday adds more clouds and a small chance of a shower near the coast, while a stronger front arrives Sunday with cooler air.
Timeline
Thursday: 80 to 86 degrees with sunshine and low humidity.
Friday morning: Northshore lows drop to 46 to 48 degrees.
Friday afternoon: Temperatures reach 78 to 81 degrees as a weak cold front passes.
Saturday: Mostly sunny with afternoon temperatures in the mid-70s.
Sunday: A stronger cold front brings a chill, with 40s on the Northshore and 50s in New Orleans in the morning, and upper 60s by afternoon.
Seasonal Patterns
The forecast follows the typical November pattern in which successive cold fronts drive a warm-then-cool sequence across southeast Louisiana. Comparison against historical averages for the region is not included in the available extraction.
Residents planning Sunday outdoor activities should prepare for morning temperatures in the 50s in New Orleans and 40s on the Northshore. Bring layers for early hours, since afternoons are forecast to warm into the upper 60s.
The takeaway
Plan for a wide temperature range this weekend, with mild afternoons and cold mornings especially on Sunday. Dressing in layers will handle both the Saturday mid-70s and the Sunday chill.
