excessive rainfall possible over the next 3 days

The next three days look very wet in southeastern Louisiana as tropical moisture moves into the area. Widespread amounts of 1-3 inches are likely, with isolated larger amounts especially closer to shore.

Tonight and tomorrow: Tonight will be mostly clear with a low around 74 degrees. Tomorrow will be the start of an uncertain weather pattern. The day starts off mostly clear. This could cause temperatures to approach 93 degrees around noon to 1 p.m. Heating will be stopped at this time as clouds move into the area. This is also the time when the chance of rain starts to increase. Scattered showers and thunderstorms are possible in the afternoon and evening. The chance of rain is greatest closer to the coast. Short periods of heavy rainfall are possible.

Next one: Next week will remain unsettled. Monday will likely be the wettest day, followed by Tuesday. During that period there may be excessive rainfall. Rain coverage will decrease a bit on Wednesday before we start to dry out a bit towards the end of the week. A small chance of rain still remains possible. Temperature-wise, it will top out in the mid-80s early in the week due to all the rainfall. After that point, highs will begin to return to the lower 90s on Thursday.

The tropics: A broad area of ​​low pressure is forecast to form over the southwestern Gulf of Mexico early next week. Environmental conditions appear conducive to the gradual development of this system, and a tropical depression could form by the middle of next week as the system slowly moves westward or west-northwestward. The development of this system will not affect our prediction.
