Acadiana's weather pattern will see several changes between now and the weekend, with a pleasant albeit mostly cloudy Tuesday, followed by a good chance of showers late Wednesday, and a blustery winter feel returning for Thursday, Christmas Eve into Christmas Day.

In the near-term expect fair skies and chilly temperatures overnight through Tuesday morning with temperatures dropping into the lower 40s to upper 30s in the northern parishes of Acadiana.

This high clouds in the region late Monday unfortunately will likely hamper viewing the "Great Conjucntion" of Saturn and Jupiter early Monday evening.

Later this evening and per the National Weather Service, a Dense Fog Advisory will be in effect for all of Acadiana from midnight through 9am Tuesday, but the amount fog development will likely hinge on the amount of high cloud cover in the region.

Tuesday will bring a mix of plenty of high clouds across the area with partly sunny skies becoming more predominant for the latter part of the afternoon.

Highs Tuesday will be in the mid-upper 60s...right where we should be this time of year.

Change will arrive Wednesday with breezy and mild conditions likely ahead of another cool front that will likely produce showers and perhaps a few thunderstorms late Wednesday afternoon into the evening/overnight hours.

Temperatures Wednesday afternoon ahead of the front will likely push the lower 70s.

No organized severe weather is expected with this system, however there will be another opportunity for some gusty winds with any storm activity and a healthy soaking with 1-1.5 inches for forecast most of Acadiana by our model guidance.

Thereafter, a winter rush of colder air and windy conditions will arrive in Acadiana Christmas eve (Thursday) with temperatures plummeting down into, and likely staying in the 40s (and will chills in the 30s) most of the day.

It could be a frosty one Thursday night into Christmas morning with lows in the lower 30s but this will by no means translate to a white Christmas except for perhaps a frost around daybreak!

Look for highs Thursday to struggle to reach into the upper 40s (with wind chills in the 30s), and in the lower 50s (sans wind) for Christmas Day under mostly sunny skies.

It will become milder again into this weekend under partly cloudy skies, ahead of our next front that should arrive by Sunday night.

The changeable pattern will likely continue well into next week...see the KATC 10 Day Forecast for the latest.
