For the third straight day Acadiana will be under a heat advisory on Friday from noon until 6 pm.

Highs are expected to reach 94 with heat indices between 105-109.

The dangerous heat and humidity will continue for the weekend with highs near 92-94 and feel like temperatures topping out between 105-109.

Thus, remember the sunscreen and to wear light fitting clothes, drink plenty of water and take breaks if you plan on being outside to enjoy the final weekend of summer before the kids go back to school.

Rain chances will be very low at only 10-20% that next couple days but a few isolated showers could be possible Sunday as a bit ore moisture will be dive down from the northeast around the area of high pressure in Texas.

The summer heat and humidity lingers into the first half of next week.

Models are indicating that a front could try to work down into the Pelican state on Wednesday into Thursday which could increase rain chances back up to 30-40% for the second half of next week.

In the tropics NOAA released their updated numbers for the Atlantic hurricane season and they have increased their number across the board.

They are now projecting 10-17 named storms with 5-9 of those systems becoming hurricanes, while 2-4 could become category 3 or stronger storms.

These numbers are slightly above the 30 year average.

The reason for the increase is because the El Nino pattern has weakened and things have switched to a more neutral pattern.

This means the upper level wind shear is expected to weaken over the main development zones in the coming months allowing for more storms to form and strength as waters continue to be slight above normal in the Caribbean and lower Atlantic.

The good news is in the short term things look to remain quiet as models show a large plume of Saharan dust pushing out of Africa into the main development zone of the Atlantic next week which will limit tropic systems from forming.
