Marine Weather and Tide Forecast for Patterson, LA

SHORT TERM
(Tonight through Sunday night)
Issued at 255 PM CDT Fri Apr 18 2025

The warmth and moisture are here! All areas are in the 80s this afternoon. Combined with dewpoints in the mid to upper 60s, it feels rather gross out there. Thankfully the breeze is present helping to make things feel a bit less sticky.

No change in the pattern for tomorrow, except developing low to the north will tighten the pressure gradient further, further increasing daytime wind speeds. Thus, a Wind Advisory has been issued for the I-10 corridor Saturday from 10 AM to 7 PM. As this frontal system starts its march to the southeast tonight and Saturday, expect winds to remain up well into Sunday. Another Wind Advisory may be needed to cover the Holiday daytime hours.

Beyond a windy Easter, there still remains a severe weather threat. Guidance has slowed further with its timing for strong storm arrival to the region. Showery weather should move in from the northwest throughout the morning. Any showers which can deepen enough may carry a localized wind risk, but generally, the greater threat doesn't appear to manifest until the later afternoon and evening.

Storms along the main front start to congeal together and move in from the west in the mid to late afternoon. Severe parameters support convection with a damaging wind risk. There may be some risk there for hail and an isolated tornado, but these scenarios are less likely with the current forecast expectation.

For those with outdoor plans on Saturday: stay cool and hydrated.
Check on those vulnerable populations while outdoors. Plan to breezy to windy conditions.

Sunday: again, very warm and humid with breezy to windy conditions. Light showers may move in through the morning. A slow moving line of storms is expected to start moving through in the afternoon and evening. Plan accordingly, and if you hear thunder, go ahead and move your plans indoors.

LONG TERM
(Monday through next Thursday)
Issued at 255 PM CDT Fri Apr 18 2025

Widespread showery activity will continue into Monday as the shortterm frontal system sags overhead. A few rumbles of thunder could be in the mix, but generally speaking, there is no expectation of severe weather. Rather, expect periods of rainfall throughout the day.

All forcing aloft washes out by Tuesday morning allowing the boundary to linger near the I-10 corridor into the midweek. With daytime heating, expect another round of showery weather with a few thunderstorms in the mix.

There could be a few periods of more enhanced weather as weak shortwave pulses move overhead Wednesday and Thursday. Combined with deep Gulf moisture, there could be a localized flood risk in areas where heavy rainfall trains.

AVIATION
(18Z TAFS)
Issued at 1234 PM CDT Fri Apr 18 2025

South winds have been stronger this morning than previous thinking, so prevailing winds have all been increased through the period. Expect elevated southerly flow to prevail through the weekend ahead of a frontal system set to move down into the area Sunday and Monday.
Cloud conditions are set to fall through the forecast period with a drop to MVFR CIGs by this evening, or 00z. Low ceilings are then likely to hang around until there is a break in the overall pattern.

Some light sea fog may move inland this evening but impacts to terminals is not anticipated.

MARINE
Issued at 255 PM CDT Fri Apr 18 2025

A tight gradient between high pressure to the east and low pressure over the Plains is bringing about a prolonged period of long fetch across the northern Gulf. This modest southerly flow will continue to result in elevated seas into early Monday. A Small Craft Advisory will be in effect for all 0 to 60 nm waters from late tonight through early Sunday morning. The next chance of rainfall comes Sunday when a frontal boundary nears the region, with scattered showers and thunderstorms expected Sunday through Monday.
