Welcome to a new week!

Low temperatures Monday morning will be falling into the lower 60s across the area under fair skies.

A little warmer heading into Monday afternoon as highs settle into the lower 80s with mainly sunny skies along with a few passing clouds from time to time.

Partly cloudy skies heading into Tuesday with high temperatures returning back into the lower 80s.

Rain chances start to increase for late Tuesday evening into Tuesday night as some tropical moisture starts to stream in from the Gulf ahead of Zeta.

On Wednesday, an upper-level trough moving in from the west coupled with tropical moisture associated with Zeta will help to give us the best rain chances of the week.

Full discussion on Zeta can be found in the tropics section below...

Strong cold front moves in on Thursday giving way to much cooler and drier weather for late week and continuing into the upcoming weekend. Have a great week!

In the tropics: Here is the latest track and intensity forecast for Tropical Storm Zeta as of 10 pm on October 25th.

The storm is still expected to reach hurricane strength by Monday.

It is forecasted to then accelerate toward the north central Gulf Coast and make landfall sometime on Wednesday afternoon as a tropical storm.

As of now, the forecast track has Zeta making landfall in SE LA, east of the Acadiana region.

However, we will continue to watch the progression of the system closely in the coming days as subtle shifts in the track in either direction are likely.

Cooler water temperatures along the northern Gulf coupled with increasing westerly wind shear by mid-week due to an approaching upper-level trough will hold the intensity of the storm in check as it nears the coastline... meaning anything worse than a strong tropical storm/weak Category 1 hurricane at landfall remains unlikely.

The increasing wind shear by mid-week will cause the storm to be more lopsided in nature with the bulk of the deep convection displaced near and well east of the center of circulation.

So, as long as we remain on the western side of the track, we will be spared from the worst of the impacts from Zeta.

Keep in mind, the forecast is still not set in stone...

We will still continue to watch closely and be prepared in the event we see changes in the forecast.
