Today: This morning should remain dry before scattered showers & thunderstorms develop in the afternoon and last until the early evening. About 40% of the area will get some more rain today. Highs should reach the mid-90s with heat index values topping near 110 degrees for some area. Due to the stronger heat, a HEAT ADVISORY has been issued for parishes in and between Baton Rouge and New Orleans. Tonight, lows will dip into the mid-70s.
Wednesday-Thursday: Shower and thunderstorm activity looks to become more widespread during the middle of the week. A stalled frontal boundary will linger just off the coast, where a low-pressure system could develop. This will increase rain coverage and even lead to heavier rainfall towards the coast. Areas along and south of the I-10/12 corridor will be at increased risk for flooding during this time. This system that develops has a slight chance of developing into a tropical depression or storm, so it needs to be monitored carefully. During the increased rain coverage, high temperatures will be limited to the upper-80s.
Friday-Sunday: Rain chances will become spottier as we enter the weekend with a little more sunshine. This will allow high temperatures to return to the low-90s. This could all change depending on how or if a tropical system develops in the Gulf of Mexico along the stalled frontal boundary.
Tracking the Tropics: A low-pressure system could develop just off the coast of Louisiana along a stalled frontal boundary in the next few days. This system has a 30% chance of developing into a tropical depression or a tropical storm in the next 5 days and just a 10% chance of developing in the next 48 hours.
