Marine Weather and Tide Forecast for Erath, LA

SHORT TERM
(Tonight through Saturday night)
Issued at 335 PM CDT Thu Apr 24 2025

Next short wave to move down into the forecast area tonight into early Friday. Guidance has not done a good job lately depicting these features. There is a small cluster of storms over northeast Texas associated with it. CAMs basically have this feature falling apart before reaching the forecast area. However, with good instability, there is a decent chance that a convective feature will be able to make into at-least the northwest half of the forecast area tonight. Therefore, will go higher than what the NBM was showing for pops for central Louisiana and interior southeast Texas. If it holds together enough, then gusty winds and locally heavy rainfall can be expected.

Moist, unstable air mass will remain in place over the forecast area on Friday with remnants of short wave/convective feature moving across. Daytime heating should help initiate scattered showers and thunderstorms, especially north of the I-10 corridor.

An upper level ridge will finally start to build in on Saturday, ending any significant rain chances, with hot and humid conditions.

LONG TERM
(Sunday through next Wednesday)
Issued at 323 PM CDT Thu Apr 24 2025

Southerly flow in the low levels will continue as a surface high over the western Atlantic ridges into the forecast area. This will continue to bring in Gulf moisture. However, an upper level ridge over northern Old Mexico is expected to build over the forecast area by Sunday and remain over the forecast area through the period.

Therefore, limited, if any, shower activity is expected.
It will feel almost summer like with hot and humid conditions.

AVIATION
(18Z TAFS)
Issued at 1232 PM CDT Thu Apr 24 2025

Airmass has been worked over enough that just isolated showers are developing across the forecast area. Expect activity to increase in coverage by 24/21z as daytime heating brings better instability. Mainly VFR conditions away from the convection. Will be watching a potential MCS moving down from Texas this evening that may affect KAEX terminal before 25/06z.

After 25/06z, as conditions become more stable, MVFR/IFR is expected from low clouds and patchy fog, that will lift by 25/15z.
