Rinse, wash and repeat will be the story of our weather this week.

Each day will start off with a decent amount of sunshine and temperatures in the mid to upper 70s.

By 10 to 11 am, and lasting through the afternoon, the daily sea breeze will kick off rounds of scattered showers and storms.

These showers/storms will be just like the ones we had over the weekend last about 20-30 minutes with some brief heavy rains but they will not been severe or cause any real flooding threat.

Thanks to the clouds and daily showers afternoon highs will top out in the upper 80s to lower 90s.

The bigger story that we will be monitoring this week is the possibility for a tropical wave to move into the southern Gulf by Wednesday.

Towards the end of the week the tropical wave is projected to slide up along the Texas Coast.

Then it could slow down and scoot along the Louisiana Coast next weekend before maybe moving onshore on Sunday or Monday.

Thus, with this wave close to Acadiana we could be looking a wet weekend, with the threat for heavy, tropical rains possible for someone along the Louisiana coast.

The latest European run has the heaviest rains just to our east, from Houma to New Orleans, where they could receive 4-8 inches of rain.

But this wave is still a week out so things will likely change, meaning the hot spot for heavy rains could maybe shift to the west over Acadiana.

Stay with KATC this week as we will continue to watch this closely and give you the latest forecast and potential rainfall projections.
