| Area Forecast Discussion National Weather Service Corpus Christi TX 1134pm CST Sunday Nov 23 2025 Issued at 1129pm CST Sunday Nov 23 2025 A brief lull in rainfall is expected through early Monday afternoon as the system responsible for the past couple days of widespread showers exits the region. On Monday, an upper-level trough moving through the Plains will draw higher moisture northward and support scattered showers and thunderstorms primarily north of us ahead of an approaching cold front. While the strongest forcing remains north of the area, portions of the northern Coastal Bend and Victoria Crossroads may still see a few isolated showers and storms. Precipitation activity should diminish by Monday night as the front weakens and pushes eastward. By midweek, high pressure spreads over the region, ushering in drier and cooler conditions. We'll see limited precipitation chances Tuesday through Thursday, with only a low chance (20-30%) of showers and storms possible across the southern CWA. Afternoon temperatures will fall back toward seasonal levels by midweek, especially following a reinforcing front expected to move through late Tuesday night into Wednesday. This secondary front will be strong enough to bring a brief return to fall-like conditions for Thanksgiving, with morning lows ranging from the mid-40s to the 50s and highs generally in the 60s to low 70s. Looking ahead to the holiday weekend, onshore flow resumes Friday allowing temperatures and humidity to gradually increase. Forecast confidence decreases by next weekend, but increasing moisture and an approaching upper-level disturbance may bring the next opportunity for rain. For now, Probability of Precipitation remain low given the uncertainty, though trends suggest the best chances may develop over the eastern half of the CWA (County Warning Area) where deeper moisture returns first. Marine Issued at 1129pm CST Sunday Nov 23 2025 A brief lull in rain chances is expected tonight through much of the day Monday before low to medium (20-50%) rain chances return Monday night through Wednesday. Moderate to fresh (BF 4-5) east- southeasterly winds, with occasional strong (BF 6) gusts, will persist through Monday night ahead of the next approaching system. These conditions have warranted the issuance of an SCA (Small Craft Advisory) through early Tuesday morning. Winds will ease on Tuesday, becoming light to gentle (BF 2-3), before a stronger reinforcing front moves offshore midweek. Behind the front, winds will shift to the north- northeast and strengthen back to moderate to fresh (BF 4-5) with intermittent strong (BF 6) gusts. This pattern is expected to hold through Friday, after which onshore flow returns. Confidence decreases heading into next weekend, but increasing moisture associated with the renewed onshore flow and an approaching upper- level disturbance may bring the next chance for rain along with fresh to strong (BF 5-6) southeasterly winds. Fire Weather Issued at 1129pm CST Sunday Nov 23 2025 Fire weather concerns will remain low through most of the period, with minimum relative humidity holding above 40% across the region. Isolated to scattered showers and storms are possible over the next few days, though rainfall amounts should remain light. Winds will strengthen today to around 10-15 mph, with gusts up to 20-25 mph, as an enhanced low-level jet and an approaching frontal boundary influence the area. Behind the front by midweek, minimum relative humidity values are expected to fall to around 20-35% across portions of the Brush Country and western Coastal Plains. However, Energy Release Component (ERC) values in the 20-50th percentile combined with lighter winds post-front should keep fire weather concerns at bay.
