The weather pattern for Acadiana will be going through some big changes through Thursday with mild temperatures and a good chance of hefty storms into Wednesday evening followed by sharply colder air for Christmas Eve and Day.

In the near term, look for southeasterly to southerly winds overnight to increase our humidity and hold our temperatures near 50° through midnight, with a slow rise into the mid-50s by morning.

Wednesday will be a mostly cloudy, breezy and mild day with the chance of a few passing showers, especially during the afternoon.

Temperatures Wednesday will top out in the 70° range.

A strong cold front will approach the area Wednesday evening, primarily between 8pm and midnight, producing widespread showers and embedded thunderstorms.

Some storms could be strong to potentially severe with a few cells possibly capable of producing damaging winds, and perhaps an isolated tornado.

While the severe weather dynamics do not appear to be too robust, the Storm Prediction Center does have all of Acadiana hatched in for a "marginal risk" for severe storms.

In addition, it appears that Acadiana will get another good soaking with rainfall totals in the 1-2" range per the latest GRAF and Euro models.

Flooding rainfall however, is not expected.

The weather will clear and turn sharply colder Thursday with a morning start in the upper 30s to lower 40s (wind chill not included).

Look for mostly sunny, windy and cold conditions Thursday (Christmas Eve) with afternoon temperatures holding in the 40s while wind chills stay in the 30s!

It will be cold into the overnight hours through Christmas morning with a light freeze expected Friday morning.

Wind chills Christmas morning could be as low as the mid-upper 20s!

It will be a nice and cool Friday afternoon with temperatures topping out in the low-mid 50s with much lighter winds so it will be great for the kids to be playing outside!

The weekend looks favorable with a slow moderating temperature trend into the 60s followed by a fizzling front Monday and perhaps a stronger weather system again next Wednesday.

For now New Year's Eve and Day look clear and chilly...consult the KATC 10 Day forecast for the latest.
