2 Rounds of heavy rain and storms Sunday

Posted: Updated:

 For the rest of this evening the warm and breezy conditions will continue along with a few scattered showers, mainly north of I-10.

After midnight but closer to 2-3AM the cold front that is producing strong to severe storms to our north towards the ArkLaTex and up through Arkansas and Missouri will finally dive down into Acadiana.

Widespread scattered showers for Acadiana will be possible from 4AM-11AM with a few strong thunderstorms mixed in as well, especially between 7AM-11AM.

For Sunday morning the Storm Prediction Center has all of Acadiana under a marginal risk (5%) for a couple storms to turn severe with damaging wind gusts up to 60 mph and the very slim chance of a quick spin up tornado.

With this first wave of showers most of Acadiana will receive 1-2 inches of rain, so a decent soaking but not looking at any flooding concerns with this round.  

Then Sunday afternoon we might get a break in the rain which will help to allow most of the early rains to drain off.

Round 2 of showers and storms looks to arrive late Sunday afternoon into Sunday evening and linger into Monday morning as a shortwave low moves off the Texas coast and right over Acadiana.

This round will bring moderate to heavy showers and storms.

For this system the Storm Prediction Center has all of Acadiana and most of the Gulf Coast under a marginal risk (5%) for a few storms to turn severe with damaging wind gusts and quarter size hail as the main threat but a brief spin up tornado can not be ruled out.

The main issue with this second wave of rain is most of Acadiana will receive an additional 1-3 inches of rain on top the earlier showers bring totals for the day into the 2-5 inch range which could lead to flooding.

The good news is the rain should move out into the Gulf by late Monday morning allowing us to dry out with some peeks of sunshine and temperatures in the mid 70s.

Unfortunately another low looks to develop near the ArkLaTex Tuesday afternoon which could produce more scattered showers and a few storms across Acadiana.

The unsettled pattern will continue Wednesday with a few hit or miss showers possible during the day before another cold front swings through Acadiana late Wednesday into the early morning hours of Thursday.

The good news is this front only looks to produce about a quarter to a half inch of rain so no flooding concerns.

Then once this front clears the area Thursday morning an area of high pressure looks to take control over much of the eastern half of the country providing some much needed dry weather for us and the Missouri, Ohio and Tennessee valleys which will be dealing with widespread river flooding following all this heavy rain the past couple weeks.

Here locally Friday through next weekend look absolutely beautiful lots of sunshine and highs in the low to mid 70s with overnight lows a little on the cool side in the upper 40s to low to mid 50s.
