Another round of thundershowers likely for Monday.
Good Sunday evening Acadiana! Just about all of the tropical rain showers are coming to an end this evening.
Low temperatures tonight will drop back into the low and mid 70s.
A deep tropical flow and a weak upper-level disturbance will remain in place across the area during the next couple of days which will keep elevated rain chances in our forecast.
We'll likely see scattered showers and storms develop as early as Monday morning resulting in a rather wet commute for some (especially south of the interstate). This activity will continue to look to build inland through the course of the day, so off and on rain showers can be expected. With abundant cloud cover overhead, high temperatures will struggle to reach the lower 80s. I know.. upper 70s and lower 80s for late July seem unthinkable!
Some locally heavy rainfall will be possible over the next couple of days..
The upper disturbance looks to lift out for mid and late week while high pressure tries to build in. This will result in our rain chances coming back down while high temperatures get back on track and climb into the lower 90s.
A more typical summer pattern will return for the weekend and early parts of next week. Let's make it a great week, y'all!
In the tropics: Hanna ran into some rough terrain on Sunday which essentially helped to dissipate the storm, but not until after it produced very heavy rainfall for southern Texas and northern Mexico. Hanna did serve as a good example of how quickly a storm can intensify in the Gulf when conditions are favorable... The Gulf basically serves as a feeding ground for tropical systems this time of year with very warm water temperatures.
Elsewhere in the tropics, the NHC has bumped up chances of development (90%) for a tropical wave that is out in the open Atlantic. It appears likely that this system will be our next named storm of the season, and I better start practicing my pronunciation of that name because it is a toughie! Regardless, it is still way to early to say where it will end up, but it does not pose a threat to Acadiana at this time.
