Dense Fog Advisory and Warm Temperatures Dominate Louisiana Forecast
Much of southeast Louisiana is bracing for a week characterized by warm temperatures and persistent morning fog, with a potential for showers and thunderstorms arriving over the weekend. A Dense Fog Advisory is in effect for most of the area from midnight through 9 a.m. Monday, February 9, 2026, prompting warnings for drivers to exercise extreme caution.
Meteorologist Malcolm Byron of The Storm Station reports that the boost in moisture overnight will lead to the development of areas of dense fog. Visibility could drop to one-quarter mile or less during the Monday morning commute. Drivers are advised to use low-beam headlights, increase following distance, and allow extra travel time.
Despite the fog, wake-up temperatures will be remarkably mild, in the low 50s. As the morning progresses, the clouds and fog are expected to gradually lift, giving way to partial afternoon clearing. The speed of this clearing will influence the day’s high temperature, with lingering fog potentially keeping highs a degree or two cooler. Generally, a high in the mid-70s is forecast for Monday.
The pattern of mild mornings with fog and warmer afternoons is expected to continue throughout the week. Lows will remain in the 50s, while highs will consistently reach the 70s, potentially nearing 80° on occasion with increased sunshine. A minor disturbance could bring a few showers on Wednesday, but attention is increasingly focused on a larger storm system expected to arrive this Saturday.
The latest data indicates a widespread round of showers and thunderstorms will move through the region on Saturday. This system is particularly noteworthy given the upcoming events on the calendar, including Valentine’s Day, LSU Baseball games, and Mardi Gras parades. While the exact timing remains uncertain, rain and lightning are likely at some point during the day or night.
Forecasters are urging residents to stay connected with The Storm Station for updates as the forecast becomes more refined. The potential for strong storms exists, though it is currently too early to determine the extent of any severe weather.
According to WAFB, temperatures are already climbing into the 70s, delivering a spring-like feel across South Louisiana. Morning fog remains a concern, while rain chances return by midweek. Current conditions in Baton Rouge, as of 56°F and misty, show a wind speed of 5 mph from the southwest. The dew point is 55°F, making it feel like 56°F. Sunrise occurred at 6:49 a.m. And sunset is expected at 5:48 p.m.
Looking ahead to Tuesday, January 6, 2026, a Dense Fog Advisory was in effect until 9 a.m. Due to widespread fog. Partly sunny skies were expected to follow, with afternoon temperatures warming into the 70s. Tuesday night will remain mild, with lows in the upper 50s, and fog may redevelop toward Wednesday. Warm and mostly dry weather is expected to hold through midweek, with highs in the upper 70s to near 80. Morning fog is likely to become more prevalent each day, and showers are possible on Thursday as a front approaches.
