KEY MESSAGES

Issued at 623 AM CDT Sun Aug 16 2026

- Moderate to major risk of heat-related impacts through next week with peak afternoon heat indices around 110

- Monitoring daily elevated fire weather potential over the Brush Country

DISCUSSION

Issued at 1243 AM CDT Sun Aug 16 2026

Little change is expected through the forecast period as mid-level high pressure expands westward across Texas early this week before gradually reestablishing over the Four Corners region around midweek. South Texas will remain beneath the influence of the ridge throughout the period, maintaining hot and generally rain-free conditions. Afternoon temperatures will continue to range from the 90s across the Coastal Bend to the Coastal Plains and around 105 degrees across portions of the Rio Grande Plains, with peak heat indices around 110 degrees at times. This will maintain a moderate to major risk of heat-related impacts across much of South Texas through the week.

Despite the gradual westward shift of the aforementioned high, sufficient ridging and subsidence are expected to persist across the region through next weekend, keeping meaningful rain chances out of the forecast. Overall, expect little day-to-day change with continued above-normal temperatures, mostly clear to partly cloudy skies, and south to southeasterly flow.

AVIATION

(12Z TAFS) Issued at 623 AM CDT Sun Aug 16 2026

MVFR VIS and CIGS are noted between ALI and VCT early this morning. Conditions improve in the next few hours with VFR conditions then through the remainder of the day. Another potential for MVFR VIS/CIGS at the same sites tonight.

MARINE

Issued at 1243 AM CDT Sun Aug 16 2026

Generally favorable marine conditions will continue through the week with persistent onshore flow. Gentle to moderate (BF 3-4) southerly to southeasterly winds are expected much of the time, occasionally increasing to fresh levels (BF 5), particularly during the afternoon and evening hours. Rain chances will remain minimal through the period as high pressure maintains its influence across South Texas and the adjacent coastal waters.

FIRE WEATHER

Issued at 1243 AM CDT Sun Aug 16 2026

Elevated fire weather conditions will remain possible through the week, particularly across the Rio Grande Plains and western Brush Country. Persistent hot and dry conditions beneath the mid-level ridge will maintain low afternoon relative humidity values across western portions of South Texas. Southeasterly winds will generally remain below critical thresholds, though occasional stronger afternoon winds may briefly overlap the lowest relative humidity values. With no meaningful rainfall expected through next weekend, drying fuels combined with the continued heat will support a persistent elevated fire weather concern.
