After strong thunderstorms produced localized damaging winds & brief heavy rainfall in Acadiana early Friday, much of the area enjoyed a brief respite from the storms with sunshine during the afternoon...the respite will be short-lived, as scattered storms will return/develop Saturday afternoon/evening with stormy conditions likely Sunday.
A cool front that crossed the area Friday is expected to become stationary Saturday morning, and then will transition to a warm front traveling back to the north Saturday night into Sunday.
Weak disturbances in the jet stream aloft will re-energize the front producing scattered showers and storms in the Gulf of Mexico Saturday with the activity drifting northward inland into Acadiana by late in the day.
Scattered showers and storms will likely continue to be a threat Saturday night with a slight risk of a few storms producing hail and/or gusty winds...the severe weather risk Saturday night should be very slight but is expected to increase significantly Sunday.
An area of low pressure will develop along the Texas Coast Sunday and will likely travel northeastward across Acadiana through Sunday evening.
Atmospheric moisture content will be very high for the time of year translating to locally heavy rains and storms that could produce 2-4" accumulations across the area...A "Flood Watch" may need to be posted this weekend for the anticipated activity Sunday.
In addition to the heavy rain threat, there may be the risk of severe storms Sunday into Sunday night with some storms possibly rotating that could produce damaging winds and isolated tornadoes.
The Storm Prediction Center has a good part of Southern Louisiana (and Acadiana) hatched in for the slight risk of severe weather Sunday with the highest risk likely south and east of where the center of low pressure crosses the state...meaning Southeast/Eastern Louisiana may see the best chance of severe weather.
The bottom line...expect a stormy weekend, especially Sunday into Sunday evening with heavy rainfall of several inches that could lead to some localized flooding...and don't be surprised if a "tornado watch" is issued for the area for a good part of Sunday...so stay tuned for further details.
