A stalled front that has been parked right along the coast the past few days will begin to lift inland overnight tonight leading to a threat for widespread heavy rainfall.
Most short-term model guidance continues to highlight a threat for flash flooding developing early in the morning hours on Thursday with that threat continuing throughout the day.
A widespread 1 – 3 inches of rain can be expected over the next 24 hours.
Considering most of South Louisiana has seen between 5-7 inches of rainfall over the past two weeks, any type of downpour will quickly lead to street flooding.
The highest threat area seems to be from the Lafayette region eastward towards New Orleans.
There is some good news for the weekend, a ridge of high pressure will build in leading to lower rain chances but that also means higher heat.
