Marine Weather and Tide Forecast for Venice, LA

LONG TERM
(Sunday through Thursday night)
Issued at 230 PM CDT Fri Apr 18 2025

Upper ridging off the Georgia and Florida coasts will remain in place early next week, although the axis will re-orient more northeast-southwest. The southern end of the trough over New Mexico will lift northeastward to the western Great Lakes by Monday night with the mid level flow across the local area becoming more zonal or at least west-southwesterly for much of the workweek next week. We won't have an actual frontal passage across the area during the long term portion of the forecast, but conditions are likely to be somewhat more favorable for the development of showers and thunderstorms. This would be mainly during the afternoon and evening hours from Monday into midweek.

Shear profiles are rather lacking on forecast soundings across the area, so at this time, severe weather doesn't appear to be a major threat locally, with the main concern to our northwest and north, generally north of Interstate 20. Similarly, forecast moisture levels are expected to be from the 50th to 75th percentile at best, climatologically, so any heavy rain concerns will also be north and west of the area.

Little day to day change in temperatures, both highs and lows, with no need to make significant changes to NBM values.

AVIATION
(18Z TAFS)
Issued at 1233 PM CDT Fri Apr 18 2025

Cloud bases are lifting, with most between FL020 and FL030 at midday. Satellite indicates that in most areas clouds are only scattered and not enough to constitute a ceiling. The exception at this point is KGPT, with an MVFR ceiling. As onshore flow becomes more fully developed this afternoon, expect KGPT to scatter out as well. Beyond sunset, as wind field weakens somewhat, moisture trapped under an inversion near 925 mb will produce MVFR ceilings, which could lower to IFR for several hours around sunrise Saturday. Conditions on Saturday should be almost a carbon copy of today, with ceilings lifting through MVFR to VFR during the mid to late morning hours. Sustained winds during the daytime hours will likely increase again to 15 to 18 knots out of the southeast or south, with occasional gusts to 25 to 28 knots, diminishing toward sunset.

MARINE
Issued at 230 PM CDT Fri Apr 18 2025

Expect several periods where winds in marine areas could approach 20 knots over the next couple of days, especially over the western waters. However, no indications of any prolonged periods where wind conditions would justify a Small Craft Advisory. With a prolonged persistent southerly fetch, seas may necessitate advisories by about Sunday over the open waters. That would be most likely over the western open waters. Will continue to monitor over the next day or so.
