Issued at 936pm CDT Monday Jun 16 2025

Earlier convection continues to diminish over land with the loss of daytime heating and air mass becoming more stable. Still looking at a very moist air mass in place and with a weakness aloft will see a chance for nocturnal activity over the Gulf that will try to make it inland before dawn along the coast.

On Tuesday, will likely see a repeat of scattered showers and thunderstorms by late morning, with latest guidance favoring higher probability of precipitation over eastern portions of the forecast area, Acadiana.

Made some minor changes, mainly to the Probability of Precipitation and weather grids based on latest radar trends and hi-res short term guidance.

.SHORT TERM... (Tonight through Wednesday night) Issued at 229pm CDT Monday Jun 16 2025

Our upper-level pattern remains steady, with a trough digging across the central Gulf Coast. While the trough is situated overhead, our wet pattern will persist, bringing widespread showers and thunderstorms today and Tuesday. PWAT (Precipitable Water) values remain elevate, above the 90th percentile, supporting a Marginal risk of flash flooding today and possibility again tomorrow. This trough will eventually begin to shift eastward as a shortwave propagates across the central Plains Tuesday night and Wednesday. At the same time, ridging will begin to build in, promoting more subsidence and leading to reduced shower activity by midweek.

Due to widespread cloud cover, high temperatures have struggled to climb out of the 80s. However, we can’t rule out a few 90s across the region.

Long Term
(Thursday through next Sunday) Issued at 229pm CDT Monday Jun 16 2025

During the second half of the week, convection will be primarily diurnally driven, with less organized activity and more airmass thunderstorms developing along boundaries. As the ridge continues to build overhead, rain chances will drop to more typical summertime levels of 30 to 50% with showers mainly in the afternoon. Showers will be scattered and hit-or-miss, generally dissipating after sunset.

With reduced cloud cover, temperatures will begin to rise into the low 90s along the coast, with a few degrees higher possible farther inland.

Marine
Issued at 229pm CDT Monday Jun 16 2025

Conditions remain calm across the coastal waters with light to moderate onshore flow last for the next several days. Combined seas will remain between 1 and 3 feet with.
