Slightly lower rain chances Sunday

Posted: Updated:

After a week of daily showers and storms several communities across Acadiana could finally dodge the rain Sunday and remain dry as a weak high pressure will slide over the northern Gulf just south of Louisiana.

That said I am still going with about a 40% chance for pop-up showers and storms Sunday afternoon, especially for the areas that saw the heaviest rainfall on Saturday. 

And like Saturday it will be another hot and humid day before the hit or miss showers arrive as highs will soar into the low to mid 90s with heat indices climbing to around 104-107, so it you are going to be outside make sure you are staying hydrated and taking it easy.

Then as we move into the new work week another frontal boundary will set up along the I-20 corridor and stall out sending Acadiana waves of energy each afternoon sparking off a 50% chance for scattered showers and storms Monday and Tuesday.

Wednesday an upper level ridge will start to form in the eastern Gulf of Mexico helping to send the boundary off to the north lowering rain chances down to about 40% during the afternoon.

By the end of the work week the ridge will slide off to the west moving closer to Acadiana helping to stabilize the atmosphere and suppress the rain chances.

However, this it is still August and we have been rather wet so we can not completely rule out the rain chances but they will be fairly low only around 20-30% for a few stray showers Thursday and Friday afternoon.

The big story towards the end of the week and into next weekend will be the return of the August heat and humidity as highs will reach the low to mid 90s and feel like temperatures will top out around 105-109 each afternoon.  

Taking a look in the tropics the National Hurricane Center is watching an area of thunderstorms developing near a board area of low pressure several hundred miles north of the Dominican Republic that is starting to get a little more organized.

Right now the hurricane center is giving the complex of storms an 80% of becoming a tropical cyclone in the next 48 hours as it moves off to the W/NW towards the east coast of America and runs into a more favorable environment to strengthen.

The models expect this system to remain off shore and out over the ocean but it could pass rather close to the beaches of North Carolina producing some high and rough seas along with bands of tropical rainfall interrupting people's plans vacationing in the Outer Banks region.
