Marine Weather and Tide Forecast for Glencoe, LA

SHORT TERM
(Tonight through Thursday night)
Issued at 1206 PM CST Tue Jan 13 2026

High pressure extends across the southeast CONUS with light winds at the surface. Aloft, our flow is mainly zonal with a 500mb low pressure located to our west, over Texas. As the low-pressure system moves closer to our area, sky cover will increase, and we could see a few light showers in the evening and overnight. As the disturbance moves across our region, its associated cold front will bring a surge of dry, cold air to the region. With no moisture return ahead of the front, rain chances will be very low, around 10%, with no measurable rain expected. Forecast soundings along with ensemble tables show a very dry environment behind the front, with ensemble tables showing moisture values below the 10th percentile aloft and RH values dropping below 30%. PWAT values are also very low dropping below the 5th percentile.

The extended forecast will remain on the cooler side as post- frontal high pressure builds overhead, keeping winds light and variable.

LONG TERM
(Friday through next Monday)
Issued at 1206 PM CST Tue Jan 13 2026

A short period of warm air advection and moisture return will occur on Friday before the next cold front moves through the region on Saturday. Similar to the previous front, this will be a dry cold front with rain chances near zero. Low temperatures will drop below freezing in central Louisiana and parts of southeast Texas and reach the 30s farther south.

A dry cold front moving across the region on Wednesday will create concerning fire weather conditions, and a Fire Danger Statement is in effect for Wednesday.
