A storm system that will develop later this week across the Southwest U.S. will march eastward this weekend bringing windy & warm conditions to Acadiana along with the possibility of strong to severe thunderstorms Saturday into Saturday night.
Although timing and intensity of this system remains unclear at this time, it appears that there will be several ingredients available for a severe weather event possible from the Arklatex into the Lower Mississippi Valley, and perhaps as far north as the Ohio River Valley, this weekend.
Locally, a strong southerly jet stream at roughly 5,000ft will develop Saturday with current models predicting winds near 60mph at that level across Acadiana. Upper level winds will be increasing and veering with height which will lead to the possibility of storms capable of producing damaging winds.
Tornadic activity nearby will not be out of the question, especially for portions of northern Louisiana into Mississippi sometime Saturday or Saturday night.
Since the details of this system are not clear the Storm Prediction Center has yet to issue any definitive outlook risk area, but that will likely change by the end of this week so check back with the link for future updates.
The threat of strong storms will also be possible through New Orleans area for those planning on attending the New Orleans Bowl with the threat there possibly lasting into Sunday.
In the near term, specifically for Acadiana, expect sunny and pleasant conditions for our Wednesday with highs in the mid-upper 60s.
Clouds will increase across the area into Thursday with temperatures reaching the lower 70s for an afternoon high.
Scattered showers and a few storms will be possible Friday with highs pushing the mid-70s.
It should become quite windy Saturday with a fairly high chance of showers and strong storms developing throughout the day, possibly lasting into the evening/night time hours.
Lingering showers and cooler temperatures will move into the area Sunday.
Monday through Wednesday (Christmas Day), looks fair and cool with highs in the 50s along with lows in the 30s.
