Marine Weather and Tide Forecast for Patterson, LA

SHORT TERM
(Tonight through Sunday night)
Issued at 250 PM CDT Fri May 16 2025

A warm and humid Friday afternoon is ongoing across the forecast area as we remain entrenched beneath upper level ridging.
Unfortunately, this pattern doesn't look to break any time soon, with more of the same warm and humid weather on tap for the weekend. Ridging aloft will keep any precipitation at bay, while breezy onshore flow resulting from surface high pressure centered near FL will keep an steady influx of warm and moist air into the region.

The combination of warm and humid air at the surface and lack of any precip will result in above average temps throughout the weekend, with highs topping out in the upper 80s to mid 90s and lows falling into the low to mid 70s. Apparent temps are forecast to peak in the lower 100s across central LA and interior SE TX each afternoon, while closer to the coast apparent temps in the mid to upper 90s can be expected. The NWS Heat Risk tool depicts Moderate to Major Heat Risk both Sat and Sun (level 2 and 3 out of 4), so heat safety should be a top priority this weekend.

LONG TERM
(Monday through next Thursday)
Issued at 250 PM CDT Fri May 16 2025

Moving into the work week, more of the same hot and humid weather is on tap for Monday and Tuesday, with highs again reaching into the upper 80s to lower 90s each afternoon amid mostly sunny skies.
However, a pattern change does finally look to arrive late Tuesday as a deepening upper level trough dives across the Plains and sends a cold front across the SErn US. Models are in good agreement with the front arriving late Tuesday night into early Wednesday morning, exiting the region by midday Wednesday. This boundary will likely be accompanied by some showers and thunderstorms, which will likely begin to affect interior SE TX and parts of CENLA by Tuesday evening, spreading southeastward from there overnight.

Any lingering convection should come to an end through Wednesday morning, as a dry WNW/NW flow develops overhead aloft and the cold front exits to our east/southeast. Dry and slightly cooler air will filter into the region throughout the day Wednesday, resulting in a rather pleasant middle and end to to the work week.
Dewpoints are forecasted to hang out in the mid 50s to lower 60s from at least Wed through Fri, while high temps top out in the low to mid 80s. After the precip accompanying the front dry weather is expected through the end of the week as well.

AVIATION
(18Z TAFS)
Issued at 1218 PM CDT Fri May 16 2025

Scattered to broken CIGs will waffle between MVFR and VFR this afternoon, eventually becoming MVFR area-wide near or just after sunset. Winds will remain breezy out of the south until sunset, relaxing overnight. As we near sunrise tomorrow, areas of IFR CIGs as well as patchy fog will be possible. This should be rather brief, with all sites returning to MVFR through the mid-morning and then again waffling between MVFR and VFR thereafter. Winds will again become breezy by the mid to late morning hours tomorrow.

MARINE
Issued at 250 PM CDT Fri May 16 2025

High pressure at the surface will continue to ridge across the northern Gulf through the weekend into early next week, resulting in several more days of light to moderate onshore flow, low seas, and dry conditions. Winds and seas begin to pick up a bit by Tuesday as a front approaches from the north, tightening the pressure gradient overhead and eventually bringing our next chance of rain by early Wed.
