Marine Weather and Tide Forecast for Glencoe, LA

SHORT TERM
(Tonight through Saturday night)
Issued at 106 PM CDT Thu Jun 19 2025

Different day, nearly same weather. Just like yesterday and days previous, isolated to scattered showers and storms are streaming northward across the entire CWA this late morning with most of this closer to the coast. Over the afternoon hours we will see an increase in coverage and intensity, however severe storms are not expected at this time. With this being mainly diurnally driven, we will see tapering going into the late afternoon / early evening hours.

A trough is extending over the eastern US down to the central Gulf Coast with our CWA on the western tail of it. As a result we are getting a bit drier WNW air moving aloft. Additionally, there is an area of high pressure out west that is steadily making its way eastward. This upper ridge will be directly overhead by tomorrow afternoon / evening. This will help suppress diurnal convection, but a stray shower or two cannot be ruled out, especially across the SE part of the CWA (Acadiana area). By Saturday, the ridge will be slightly off to our east, giving near similar conditions with only isolated PoPs. With the ridge coming in and less coverage expected, MaxTs will rise a few degree or so. MinTs will be remain in the low to mid 70s.

LONG TERM
(Sunday through next Wednesday)
Issued at 106 PM CDT Thu Jun 19 2025

We can expect a bit of a pattern change as the upper high migrates NEwrd. We will see an increase in moisture along with an increase in PoPs. This pattern will trend more towards the return of a wet period as ESE flow becomes established aloft while the upper ridge meanders about the Eastern US / Appalachians. Each day of the long term we can expect isolated showers and storms along our northernmost Counties and Parishes, then scattered to numerous from there down to the Gulf. While overall rainfall "coverage" seems to be high, rainfall amounts at this time are expected to be low, hence the rainfall threat is low. Nevertheless, this will need to be watched in the coming days.

Temperatures will be dependent on cloud cover and rain chances, however it will hover at or above climatological normals for this time period. It will feel quite summery, though, thanks to the nonstop flow of Gulf moisture. Each day, max heat indices will be in the 100-106 range.
