Tonight: Clouds return to Southeast Louisiana ahead of Monday’s system. Temperatures will still be cold in the 30s.
Monday & Tuesday: Off and on rain through Tuesday morning as a low pressure in the Gulf of Mexico moves across the northern Gulf of Mexico. Highs in the 50s. Lows in the 40s. Rain totals will be around 1 to 2 inches with locally higher amounts.
Wednesday: First day of winter and it will feel like it! High temperatures in the 50s and 60s. Overnight temperatures will be in the lower 40s.
Thursday: A strong cold front will bring Arctic air down to the Gulf Coast late in the week and heading into Christmas weekend. The front will likely move in late Thursday and into Friday. Temperatures will likely drop like a rock about 30 degrees within a few hours. Some rain is possible ahead of the front and a couple of flurries may fall, but not stick. The snow chance will stay to our north. Overnight temperatures will drop down into the teens and 20s by sunrise Friday. Protect people, pets, plants, and pipes!
Friday – Christmas Day: Very cold air will stay in place and highs will likely only be in the 30s Friday and Saturday. Some may not even warm above freezing on Friday and the wind will make it feel like the teens all day long. Highs on Christmas Day may be in the 40s. Morning low temperatures in the teens and 20s. Again, prepare for a long duration hard freeze! Protect people, pets, plants, and pipes!
