SHORT TERM
(Tonight through Sunday night)
Issued at 348 PM CDT Fri Jul 26 2024
Another day of showers and storms ongoing across the area in this multiday flooding event. Widely isolated showers are covering a majority of the CWA with some heavier showers across central and south central Louisiana.
Aloft, the trough is still over the central CONUS with one ridge over the SW and another over the Gulf. Over the period, we will see an expansions of the upper ridges over the CWA At the surface we have an area of high pressure off to the NE of here, with southerly to southeasterly flow prevailing. While not nearly as high as days previous, PWATs are still high and additional showers and storms will continue. Higher amounts are expected near the coast going into tomorrow, hence the expansion of the Flood Watch.
Rainfall totals and overall coverage will decrease through the period with temperatures slightly warming.
LONG TERM
(Monday through next Thursday)
Issued at 348 PM CDT Fri Jul 26 2024
A relatively drier period continues to set up through much of the upcoming week as upper level ridging builds across much of the northern gulf coast. Isolated, diurnally driven convection will still develop each afternoon with the highest probabilities within the highest moisture profiles across lower Acadiana. As has been the case in previous forecast packages, opted to undercut NBM PoPs Monday through Wednesday as they seem to significantly exceed the forecast environment.
With the ridge suppressing both convection and cloud cover, afternoon highs will climb back into the low to mid 90s bringing an end to the brief reprieve from the summer heat. Consistent weak high pressure over the Northeastern gulf coast will maintain steady, light southerly winds through much of the week keeping dewpoints in the upper 70s which will push apparent temperatures into the 100-105 range each afternoon.

Showers and storms will continue across the area for the remainder of the afternoon and into this evening. Both CIGs and VIS will be dancing between categories as a result of the intermittent activity. While some tapering can be expected later tonight, we will see yet another round tomorrow morning.
