Periods of rain and eventually a few rumbles of thunder will be likely for Acadiana overnight into Thursday.
An area of low pressure aided by an increasingly more active sub-tropical jet stream will traverse eastward through Southern Louisiana Thursday allowing for rather wet conditions across the area.
And as the jet stream dynamics become more in play toward daybreak Thursday, a few rumbles of thunder and locally heavier showers will be possible.
The rains and embedded storms will advance east of the area by later Thursday afternoon with drying conditions moving in overnight through Friday morning.
There remains a fair bit of disparity on rain accumulation estimates by the models with the RPM being the wettest, the HRRR Model looking underdone, with the Euro Model as a compromise somewhere in between.
But like many rainy winter systems this year and over the past several years, rainfall amounts usually outperform most of the models, so expect anywhere between 1-2" after all is said and done.
No flooding nor any severe storms are anticipated at this time.
Temperatures will gradually rise overnight with our lows (in the upper 40s) right around midnight reaching the mid-50s by morning.
Temperatures will briefly become milder into Thursday afternoon with highs in the upper 60s.
Readings will chill down again into Thursday night with lows Friday morning dipping into the low-mid 40s.
Look for a sunny and seasonable day Friday with highs right where they should be, in the lower 60s.
Saturday will start off partly sunny but should cloud-up during the afternoon as the next low pressure system to impact the area heads for the Gulf of Mexico Sunday.
In fact, we now have a wetter forecast in place for Sunday, with periods of rain now a fairly good bet, especially for Sunday morning and for the coastal parishes.
The weather pattern next week is beginning to look rather unsettled after Monday with up and down temperatures and rain chances an excellent bet.

It does appear that Acadiana will finish the month with near or below normal temperatures that could last into a good part of the first week of February...it is winter after all!
