Acadiana is on track for a good soaking for the latter half of the weekend, with a rather unsettled, milder, and occasionally wet pattern through much of the week that follows.
It's going to be quite a chilly to start the weekend with morning low temperatures in the mid-upper 30s, and perhaps closer to freezing in the northern parishes of Acadiana, so make sure the tender plants are covered, and the pets have a warm place to stay.
Saturday will start off on the brighter side with some sunshine dulled by high level cirrus clouds that will likely thicken during the day. Highs will be in the upper 50s Saturday afternoon and we'll likely hold in the upper 40s to lower 50s Saturday night.
Moving into Saturday night and Sunday, a fairly strong upper disturbance rolling out of the Southwest U.S. will allow for a surface low pressure system to develop in the Western Gulf of Mexico Saturday night, with this system moving northeastward across Louisiana Sunday.
This system will likely bring showers and thunderstorms to the area, with a few of those storms possibly on the strong side.
The Storm Prediction Center does have a good part of Southern and Southeastern Louisiana hatched in for a marginal risk of a few isolated severe storms that could produce damaging winds, and perhaps some hail.
While widespread flooding is not anticipated, 2-3" of rain will be likely for a good portion of Acadiana through Monday with isolated spots possibly receiving more that could lead to brief, localized street flooding.
The sub-tropical jet stream is expected to stay planted across the Gulf States through much of next week, which will ultimately translate to a mostly cloudy, milder and occasionally wet pattern all week.
Temperatures will climb into the lower 70s as early as Sunday, and will likely be in the upper 60s to low-mid 70s through Friday...then it gets even more interesting!
Per the European Model, colder air will return to the area for next weekend, while the sub-tropical jet remains in place. Therefore, the weekend before Christmas look cloudy and significantly colder with temperatures dropping into the 40s, and perhaps the mid-upper 30s at night with a good chance of cold rains developing for Christmas Eve.
While it's too far out for an accurate Christmas Day forecast, a wintry mix might just be possible for some spots in Louisiana on Christmas Day...but whether that would include Acadiana, is too early to tell.
We can say though, much of Texas (and areas to the north and east, may indeed see snow and ice in the days leading up to Christmas. so it could be a "White Christmas for our friends in the Lone Star State...and we'll have to just wait and see if Acadiana can beat the 1 in 900 chance for a white one here!
