KEY MESSAGES

- Moderate rainfall chances through Sunday night

- Minor coastal flooding and High risk of rip currents along the Gulf-facing beaches through this evening

- Marginal to Slight Risk of Severe Weather Sunday

DISCUSSION

Issued at 321 PM CDT Sat Apr 11 2026

Isolated to scattered showers will continue to impact inland portions of South Texas this afternoon with accumulations generally less than a tenth of an inch.

A persistent southeasterly wind will allow for deeper moisture to surge into the area tonight with PWATs rising to near 2.0" by Sunday afternoon. The combination of a couple of mid to upper level disturbance tracking in the southwesterly flow aloft, moderate instability with CAPE values nearing 1500-2500 J/kg, a weak cap, and very steep lapse rates will lead to an increased potential for convection on Sunday. Although SPC has maintained a Marginal to Slight risk of severe weather (levels 1-2 of 5) Sunday into Sunday night, uncertainty remains fairly high in regards to the exact timing and severity of the event in our area. Some of the latest CAM runs indicate a later development timeframe of the storms over the Sierra Madre and a delayed advancement into South Texas, if the storms are able to maintain themselves. Though the current forecast generally calls for PoPs in the 30-60% range tomorrow into tomorrow night, the high level of uncertainty makes for a lower confidence on timing. Having said that, per the RRFS, the most likely timeframe for severe weather will be Sunday evening into the the overnight hours.

The rest of the forecast period is looking relatively quiet with slight rain chances returning around mid week across our western zones in response to another trough transitioning into the Southern Plains. Temperatures will gradually increase through the week.

In regards to coastal conditions, minor coastal flooding is ongoing along the Gulf-facing beaches with tides reaching 1.6-1.7 ft at high tide, while have remained below Advisory criteria over the bays. Therefore, have cancelled the Advisory for the bays, and maintained it in effect over the Gulf. Although winds will increase tonight with the flow offshore becoming moderate to fresh, swell heights and periods have subsided. Will continue to monitor conditions tonight in case another Advisory is required. The High risk of rip currents remain in effect through tomorrow evening.

AVIATION

(18Z TAFS) Issued at 321 PM CDT Sat Apr 11 2026

VFR conditions will generally prevail through this evening, before falling to MVFR/IFR levels late tonight into early Sunday morning. Isolated to scattered showers could impact the terminals this afternoon but overall confidence is moderate. Another chance will come in Sunday morning primarily at ALI/COT/VCT sites, but uncertainty remains high in regards to the location of the surface trough. Otherwise, expect breezy southeasterly winds through much of the cycle.

MARINE

Issued at 321 PM CDT Sat Apr 11 2026

A Moderate to Fresh (BF 4-5) onshore flow will dominate the forecast through much of next week. Expect low to moderate rain chances over the waters tonight through early Monday with dry conditions the remainder of the week.

FIRE WEATHER

Issued at 321 PM CDT Sat Apr 11 2026

Low to moderate rain/thunderstorm chances across the region continue through Monday morning. The Brush Country and Rio Grande Plains are under a Slight risk (level 2 out of 5) for severe weather on Sunday with rest of South Texas under a Marginal risk (level 1 out of 5). Strong winds and large hail will be the primary threats through Sunday evening. Due to the abundant moisture and precipitation chances, elevated fire weather conditions are not expected at this time.
