DISCUSSION

Issued at 125 PM CDT Wed Mar 11 2026

Minor coastal flooding is surprisingly the greatest impact across South Texas early this afternoon, with elevated swell heights and wave periods enhancing wave runup, causing water to extend over beach roads and approach the dunes of the Middle Texas Coast. High tide will occur over the next couple of hours but greater than normal inundation will continue through this evening. Elevated fire weather conditions are beginning to develop over the Brush Country and southern Coastal Plains where relative humidity is dropping below 30% and winds are gusting to around 20 mph or more. We can expect elevated fire weather conditions most afternoons over the Brush Country into early next week.

Following today's slowly eastward moving boundary/dryline, surface high pressure will surge southward, pushing a cold front the area. Northerly winds have trended stronger in the wake of the front, with medium to high (50-80%) HREF probabilities of wind gusts over 40 mph inland and over the waters. Therefore, a Wind Advisory is in effect from 10 PM tonight through early Thursday morning across the Coastal Plains, all are urged to secure loose outdoor objects. Gale conditions will be in place around the same time-frame, causing dangerous marine conditions for all mariners. Winds begin to relax late Thursday morning into afternoon as the surface high centers over the Texas Coast. Relaxed winds, clear skies, and drier air will set the stage for a below normal cool night across South Texas, causing morning Friday lows in the mid to upper 40s!

Onshore flow returns Friday, creating a dominate warming trend through Sunday before a deep amplified mid-level trough swinging across the Central Plains surged a strong cold front across the region Sunday night into Monday morning. Moisture will struggle to return so rain chances remain silent, but it'll bring another break from the heat.

AVIATION

MARINE

Issued at 125 PM CDT Wed Mar 11 2026

Gentle to moderate southwesterly flow will continue through this evening before a strong cold front surges through late tonight into Thursday morning. Strong to near Gale force winds will follow in the wake, therefore a Gale Warning is in effect for all waters from 11 PM tonight through 7 AM Thursday before getting replaced by a Small Craft Advisory through mid-afternoon Thursday. In addition to strong winds, seas up to 10 feet are expected over the offshore waters. Winds relax to light to gentle Thursday night, then shift back onshore Friday strengthening to gentle to moderate Friday night. Moderate to fresh onshore winds persist this weekend before another strong cold front is expected to bring strong to near Gale force northerly winds in the wake Sunday night into Monday. Minimal rain chances into next week.

FIRE WEATHER

Issued at 125 PM CDT Wed Mar 11 2026

Relative humidity values are dropping near or below 30% across the Brush Country and southern Coastal Plains early this afternoon. Northwesterly winds are occasionally gusting to around 20 mph. Therefore, elevated fire weather conditions are in effect through this evening for the aforementioned areas and will likely be occurring each afternoon into early next week. Winds will be noticeably lighter than today through the week, so fire weather concern will be limited. Onshore flow returns Friday along with a warming trend, before another strong cold front pushes through Sunday night into Monday morning. No rain chances heading into next week.
