Marine
.SHORT TERM... (Tonight through Saturday night) Issued at 150pm CST Fri Dec 8 2023

- Gale Force winds Saturday evening through late Sunday morning

- Low chances of rain across across the Coastal Bend and Victoria Crossroads

Current PWAT (Precipitable Water) values near 1.20" will gradually increase to around 1.40" by Saturday afternoon as onshore flow continues to usher moisture into the region ahead of our next cold front. The cold front is anticipated to sweep across the region Saturday evening into Saturday night with cooler air filtering in behind the front. However, temperatures ahead of the front will remain above-average with most locations climbing into the 80s Saturday afternoon. Rain chances continue to be slim to none across the region due to unimpressive forcing associated with the front. Windy conditions are expected in the wake of the front with Gale force winds offshore and 20-25 mph overland with the exception of coastal areas. There is currently a medium chance of wind advisory conditions (winds 30-39 mph for over 1 hour) across the portions of the Coastal Plains. Temperatures Saturday night are expected to drop into the lower to upper 40s with the barrier islands dropping to the lower 50s. Another round of fog is expected late tonight into tomorrow morning with patchy to areas of fog across most of South Texas, especially inland areas.

Long Term
(Sunday through next Thursday) Issued at 150pm CST Fri Dec 8 2023

- Medium to high (40-75%) chance of below freezing temperatures Sunday night across portions of the South Texas

- Rain chances return by mid-week next week

Windy conditions are expected to continue through Sunday with winds beginning to decrease Sunday evening into Sunday night as high pressure settles into the area. The probabilities of freezing temperatures Sunday night into Monday morning have increased slightly to 40-75% for the northern counties of South Texas from McMullen to Victoria, especially in areas low-lying drainage areas. With windy conditions in the wake of the front and drier air moving into the region, elevated to critical fire weather conditions will be possible from Saturday evening through Saturday night. With onshore flow quickly returning in the wake of the front, daytime highs are expected to warm into the 70s but Monday as moisture returns to the region.

Global models remain consistent in trekking an upper-level disturbance across South Texas along the sub-tropical jetstream. With the upper-level disturbance and forecast PWAT (Precipitable Water) values near 1.50", rain chances are forecast to increase across the region. As of right now, we currently have a low (20-40%) chance of showers and thunderstorms Wednesday through the end of the work week. A moderate easterly flow from Wednesday into Thursday could lead to an increased threat for minor coastal flooding and moderate to high risk of rip currents.

Marine
Issued at 150pm CST Fri Dec 8 2023

Moderate to occasionally strong (15-22 knots) southerly flow is expected to continue this afternoon into tonight, decreasing back to under 15 knots Saturday ahead of the cold front. Winds are expected to veer to the north Saturday evening in the wake of the front with Gale Force winds from 30-40 knots and gusts up to 45 knots until late Sunday morning. Winds will begin to decrease Sunday afternoon into evening and high pressure moves into the area. There is a low to medium chance of showers and thunderstorms across the local waters with the front with the best chances remaining well offshore.
