Marine
.SHORT TERM... (Tonight through Sunday night) Issued at 414pm CST Sat Feb 15 2025

- Cold front clearing the region this evening

- Potential for a Gale Warning needed Sunday

As we take a look at satellite, the cold front has pushed through much of the region and will continue to push offshore over the next couple of hours. A surface high will allow for colder drier air to continue filtering into the region tempering highs Sunday to the 60s. Expect low temperatures to be chilly as well dipping down into the 30s to the north with 40s along the coast and to the west Sunday night. This high is expected to tighten the pressure gradient over the waters allowing for winds to increase to at or near gale force tomorrow. In addition to this, humidity values are expected to drop in the wake of the front which could lead to some elevated fire weather concerns. We will monitor these possibilities overnight and into tomorrow, therefore continue to check back for future updates. Conditions will be quiet to begin the week as temperatures warm briefly ahead our next front with onshore returning.

Long Term
(Monday through next Friday) Issued at 414pm CST Sat Feb 15 2025

Key Messages:

- Cold front Tuesday into Wednesday with a moderate chance for showers.

- Gale conditions possible Wednesday over the waters.

Several mid-level Canadian lows and a Pacific NW low will impact our weather over the next week or so. As these low pressure systems move across the northern CONUS they will eject a strong cold front southward across the region Tuesday into Wednesday. This will be followed later in the week with a surge of high pressure allowing for arctic cold air to infiltrate South Texas.

This will allow for a low to moderate (30-50%) chance of rain Tuesday mainly across the Victoria Crossroads. Shower activity is expected to taper off overnight Tuesday into Wednesday. The coldest temperatures will be overnight Wednesday into Thursday morning with lows generally in the 20-30s across all of South Texas. The islands will approach or reach freezing as well. Expect windy conditions behind the front Wednesday with gusts near 40 MPH possible. A low (20-35%) chance will exist for winds to meet Wind Advisory criteria. Thursday, highs will max out in the low to mid 40s to around 50 degrees near the coast with weak to moderate northerly winds.

Looking ahead to next weekend currently expecting a low to moderate (20-40%) chance for rain mainly near the coast as another disturbance brings in a plume of deep moisture over the region from the remnants of an Eastern Pacific Low.

Marine
Issued at 414pm CST Sat Feb 15 2025

Moderate to strong southerly flow is expected to turn more northerly in the wake of the front overnight with winds weakening back to moderate levels by Sunday evening. The possibility for a Gale Warning will be monitored so continue to check back for future updates. Weak to moderate onshore flow is expected Monday through Tuesday ahead of our next front. A very strong cold front is expected to move across the region late Tuesday. There's a moderate chance for Gale force winds across the Gulf waters on Wednesday after the cold front moves offshore. Look for a moderate to high chance for showers over the waters Tuesday through Saturday of next week.
