Full summer heat and humidity remains in the forecast cards for Acadiana over the next week or more, but there should be slightly better odds for scattered afternoon storms toward the end of the week, and perhaps into the first part of the weekend.

High pressure aloft and at the surface should weaken enough to permit for a few more afternoon storms Wednesday with rain chances getting back to near 30-40%.

High temperatures will still push the low-mid 90s before any cooling thundershowers get involved.

Much the same is expected for Thursday, Friday and Saturday with afternoon storm chances near 40% along with highs still managing to reaching the low-mid 90s.

The forecast for Sunday into early next week appears to be getting hotter with a northerly wind developing at the surface and aloft.

This means daytime highs could push into the the mid-upper 90s into early next week with just a slight chance of a late afternoon strong storm possible.

See the KATC 10 Day Forecast for the latest.

Meanwhile the tropics appear to be perking up again with a new wave emerging off of the African Coast and a new tropical depression in the mid-tropical Atlantic identified the the National Hurricane Center.


Tropical Depression #11 formed in the Atlantic Tuesday afternoon and is expected to become a tropical storm by Thursday.

The system, roughly 1,450 miles east of the Lesser Antilles in the Eastern Caribbean, was moving to the west at 16 mph with sustained winds near 35 mph.

If the depression gets upgraded to a tropical storm, the next name on the list is "Josephine"..much easier to pronounce for most of us!

TD11 may have a limited future as the system will be encountering upper level shear (strong winds aloft) as it nears the Northeast Caribbean this weekend.

The system could weaken and perhaps dissipate beyond 5 days as it encounters an anticipated upper level trough of low pressure along the U.S. East Coast.

TD11 should not pose a threat to the Gulf of Mexico, unless it is bypassed by the aforementioned trough in a week's time...a very low end scenario at this time.

With such an intense hurricane season expected this year all systems will garner monitoring, even if they are only tropical waves.

Elsewhere, there has been consistent suggestion that low pressure will form near the Mid-Atlantic states this week which could become a tropical or sub-tropical system prior to moving out to sea this weekend.

Of note, the longer range Euro Model does show plenty of deep tropical moisture pooling in the Western Caribbean 9-10 days out along with some very healthy looking tropical waves farther east into the Atlantic...these features could signal more activity to come.

The prime of hurricane season is just weeks away. Be prepared!
