A front will push into the area today, and slow down. Tons of moisture is moving northward out of the Gulf of Mexico. These combined will set the stage for a rainy Friday, Friday night, and possibly early Saturday morning. Most areas are waking up to light to moderate rainfall, and will probably go to bed with rain as well.
An upper trough will dig across the middle part of the country, and cut off somewhat. This is the reason the front will slow to a crawl. It appears the heaviest amounts of rainfall will probably move across central Acadiana and points eastward. The potential for 2-3 inches of rainfall is there, with isolated amounts up to 5 inches. Fortunately, this rainfall will be falling over a 24-36 hour time period. Therefore only minor flooding will be expected as most of the rainfall will be able to soak in.
Most flash flood guidance allows 2-3 inches of rain in an our, with 5-6 inches of rain able to be taken on over a 6 hour period. As of this writing, flood watches are only posted for St. Landry, St. Martin, Iberia and St. Mary Parishes.
Rain will continue into the evening hours and possibly overnight. Saturday, we can expect some showers during the morning, with rains gradually ending. Expect some clearing by Saturday afternon. Sunday looks great with sunny skies and a high of 72.
