It’ll be a warm Sunday with lower humidity. Heavy rain will be possible by Wednesday. We’ll dry out and cool down for Halloween.

NEW ORLEANS — Quiet, pleasant weather is expected for the rest of the weekend after a weak front moved through early Saturday. 

Look for a mostly sunny and less humid Sunday. It won’t be drastically cooler as temperatures climb to around 80 degrees in the afternoon.

Monday will be a little warmer with more clouds, then a few spotty showers could form Tuesday.

The highest chance for rain and storms this week is on Wednesday as a stronger cold front approaches and moves through late to set us up for a cooler end of the week. 

Of course, a major thing we’ll also have to watch is Tropical Depression 28 in the Caribbean Sea. It will soon be Tropical Storm Zeta and will enter the Gulf on Tuesday. 

Soon-to-be Zeta’s path isn’t certain, but it will likely bring tropical impacts somewhere along the Gulf Coast on Wednesday. A potential landfall is forecast as a tropical storm on Wednesday afternoon somewhere between southwest Louisiana and western Florida. 

It’s too early to say exactly what impacts might be for southeast Louisiana, because there are still unknowns. A lot will depend on the exact landfall location of the storm, plus how much it is able to organize.

At this point it looks like we may get some rain from it on Wednesday. Models show about 1-2 inches of rain for our area, but of course it’s still days away and that could change. If soon-to-be Zeta does make landfall around our area, we would also have coastal flooding and wind issues.

However, there are a few factors that will influence the eventual track. The cold front set to arrive late Wednesday could keep big impacts away from us depending on its timing. Also, it’s unclear just how strong the depression will eventually get. If it stays weak, it would be a messy system where most of the rain is displaced far east of the center.

A few things we have going for us is that this likely won’t be extremely intense at landfall. The current forecast is for a tropical storm. Also, it will be moving fast – it should accelerate over the northern Gulf due to a trough of low pressure driving the midweek cold front, so any tropical impacts wouldn’t hang around for long.

Also, it’s important to remember that the average error for a system’s location four days out is 160 miles – so if the center is over southeast Louisiana right now, it will likely shift east or west in the coming days (as we’ve seen most of the other six times we’ve been in a cone of uncertainty this year!).

For now, we have rain chances increasing Wednesday with the frontal passage set for early Thursday, then much cooler weather Friday and next weekend.

More updates will be coming.
