| Area Forecast Discussion National Weather Service Corpus Christi TX 542pm CST Tuesday Jan 6 2026 Issued at 1227pm CST Tuesday Jan 6 2026 Main hazard tonight will be the reduction of visibility brought on by fog. A weak boundary that has brought pleasant dewpoint temps to the Hill Country will slowly sag south and stall out near a line from Del Rio to San Antonio. This is where models are showing the greatest surface convergence to support the densest of fog roughly starting around midnight and then expanding toward the coastal counties throughout the early hours on Wednesday morning. A Dense Fog Advisory will need to be reevaluated for Wednesday morning given the latest evening model runs. In terms of sea fog, water temps are still hovering between 65-68F and with dew point temps remaining around 70F and a stronger onshore wind, the possibility of sea fog will still remain present overnight until the next big wind shift. Speaking of the next wind shift, our long-awaited cold front is forecast to moved through the region on Friday, with locations closer to the Rio Grande in the morning and entering the Gulf waters Friday night. Prior to the frontal passage, we'll have to get through some pretty warm days with high temperatures in the 80s (except along the barrier islands/immediate coast) and lows in the 60s (checks calendar... yes, this is January). This frontal passage is looking to be dry with most of the jet dynamics to support any rainfall will remain will north and east of here. That said, locations in the Victoria Crossroads have a 20-30% chance of rainfall on Friday. Once the front moves through, we'll slip back into an overrunning pattern leading to mostly cloudy with spritzes of of raindrops on Saturday and less so on Sunday. Greatest accumulations will be closest to the coastline (a few hundredths of an inch at best). Dry air also filters in behind the front leading to widespread minimum relative humidity values in the 20-30% this weekend. Coupled with stronger 20 ft winds, this will elevate the fire risk this weekend (and thus limiting any meaningful rain accumulations). This drier air also means cooler weather (well, cooler than it has been). Temps will struggle to get out of the 50s Saturday through Sunday with lows in the upper 30s to mid 40s. Across the marine zones, this cold front will lead to hazardous conditions for mariners before and after the frontal passage , so Small Craft Advisories will be reevaluated in subsequent forecast packages based on the latest model guidance. Welcome to Texas in January! Marine Issued at 1227pm CST Tuesday Jan 6 2026 A cold front moving through early Saturday morning will be the main driver of conditions ahead and after the front passage. Onshore flow increases to moderate to fresh strength (BF 4-5) on Wednesday with seas increasing to 2-4 ft and then to 6-8 ft late Wednesday night through Thursday morning. By then, onshore flow will increase to fresh to strong (BF 5-6) strength. Then, onshore flow will remain near moderate strength until the frontal passage early Saturday, at which point the winds will be out of the north at 20-25 kts sustained gusting near 30 kts with seas increasing to 7-10 ft. By Sunday night, offshore flow will decrease to moderate to fresh strength with 2-4 ft. After the frontal passage, daily chances (20- 40%) of showers will continue through the upcoming week. Fire Weather Issued at 1227pm CST Tuesday Jan 6 2026 Minimum relative humidity values are expected to remain above 35% through Thursday, limiting the fire risk to low. Our next cold front moves through South Texas throughout the day on Friday leading to locations in the Brush Country and Rio Grande Plains to see min RH values drop to 20-30%, while remaining above 40% along the Coastal Plains. Saturday and Sunday will see widespread min RH values between 20-30% all the way toward the immediate coast. During the weekend, 20 ft winds will increase to 15-20kt increasing the fire risk to elevated. While an overrunning pattern will bring isolated showers/drizzle, it'll still be worth monitoring the fire risk in the subsequent forecast as Energy Release Components increase from around the 60th percentile on Saturday to near the 80th percentile on Sunday.
