Lafayette Weather – More Tropical Downpours Today
The long stretch of hot and dry conditions across Acadiana has again yielded to the ever present Gulf of Mexico moisture. Currently, a huge plume of moisture is being lifted up from the Gulf across Acadiana by the very same high pressure system that gave us the dry weather last week.
This influx of abundant moisture combined with instability in the atmosphere will create another tropical downpour situation for the area. While many parts of Acadiana will see rain and maybe a thunderstorm today, some locally heavy amounts of precipitation are possible. It is also possible that rainfall could come in a very short time. This might lead to some flash flooding of areas that do not drain well.
The current forecast models suggest that some parts of Acadiana could see as much as 3 inches of rain before the atmosphere begins to dry out for the weekend. Dave Baker currently has the rain chances at 60% for today and 70% for tomorrow.
