Marine Weather and Tide Forecast for Groves, TX

DISCUSSION
(Tonight through next Saturday)
Issued at 1126 PM CST Sat Nov 7 2026

Surface high pressure centered over the Mid-Mississippi Valley will build into the forecast and slide south toward the Gulf South as it settles in and weakens.

The low level northeast flow will bring a dry continental air mass to the forecast area to provide low humidity with mild daytime temperatures and cool nights into Monday.

Meanwhile, an upper level low over northwest Old Mexico will get caught up in the southern jet and move eastward into early next week. However, low levels look to remain on the dry side, so this system is only expected to bring extensive high level cloudiness.

By mid-week, a northern stream short wave will deepen as it rounds an upper level low over Ontario and dives into the southeast US.
This will bring a Canadian cold front across on Wednesday night.
Gulf never really opens up ahead of this front with moisture values rather shallow and limited. Therefore, only a slight chance for showers and if any were to develop ahead of the front, any sort of significant or "wetting" rainfall looks unlikely at this time.

This front will reinforce the dry conditions into the end of the week. Quite cool overnight lows will be possible next weekend with readings from the mid 30s to mid 40s.

Issued at 1126 PM CST Sat Nov 7 2026

Surface high pressure over the Mid Mississippi Valley will slide south and ridge into the coastal waters for the remainder of the weekend. A moderate northeast flow is expected at times with wind speeds around 20 knots and a small craft advisory this morning west of Cameron. Winds will remain offshore Monday and Tuesday however decrease as high pressure settles over the region. No rain is expected into early next week as a dry air mass will be in place.

FIRE WEATHER
Issued at 1126 PM CST Sat Nov 7 2026

Surface high pressure will keep northeast flow at the surface and bring in a dry continental air mass to the fire weather region into early next week. This will allow for low minimum afternoon relative humidity values between 30 and 35 percent today and Monday over southern and central Louisiana, and around 40 percent over southeast Texas. Vegetation in many locations remain rather dry and rain is not expected for the next few days. However, wind speeds look to be light, and at this time will hold off on any fire danger statement for today, and will reevaluate for Monday over the next day.

LCH WATCHES/WARNINGS/ADVISORIES
