NEW ORLEANS (WGNO) — Fog will be a big issue again tonight and Wednesday morning. A dense fog advisory is in effect for the entire area from midnight to 10AM. Expect very low visibility especially in the usual areas near water. Give yourself plenty of time and remember to turn your lights to the on position. Wednesday will be warm again before a cold front moves through later in the day. Look for low to mid 70s through the afternoon. A few showers will be possible late in the day behind the front but most of it fades out as it moves south. After the front moves through Wednesday night we will see temperatures back to around normal for this time of year with lower humidity. Highs will be in the mid 60s Thursday and Friday.
