NEW ORLEANS (WGNO) — The next couple of days will be mostly dry with just a slight chance of isolated showers during the afternoon. High pressure is building in, leading to slightly warmer than average temperatures for this time of year. Daytime highs will be in the mid-90s, and heat index values could reach the low 100s. Be sure to stay hydrated and take precautions against the heat. Later in the week, there is some uncertainty regarding potential tropical activity in the Gulf of Mexico. A disturbance in the central and eastern Gulf has a high chance of developing over the next seven days. While it’s still too early to predict exactly what may happen, the development could occur by Wednesday or Thursday. A frontal system moving through the Southeast could affect how any tropical system forms or behaves. It’s important to keep an eye on updates as the situation evolves, but it's still too early to pinpoint specifics on where it will go or how strong it may be.
