DISCUSSION

Issued at 126 AM CDT Mon Aug 10 2026

Not much change in the forecast this period. We are currently still caught between two ridges with moisture and mid-level energy bringing some convection toward the coast during the daytime. Today looks a little less conducive for a continued active sea-breeze, but models are suggesting scattered showers/storms along the coast in the morning and into the afternoon, especially for the northern Coastal Bend has energy rotates northward around the eastern ridge.

Seasonal temperatures are expected with a very slight uptick toward the second half of the week. Highs will be above 100 daily over the Rio Grande Plains and in the 90s east. Heat index values increase for the latter half of the period and heat advisories may become necessary by mid-week.

Issued at 126 AM CDT Mon Aug 10 2026

Light to moderate onshore breezes Monday will increase to a more moderate breeze, with periods of fresh breezes, Tuesday through the end of the week. A low to medium (20-50%) chance of showers and thunderstorms will continue Monday with mainly dry conditions thereafter.

FIRE WEATHER

Issued at 126 AM CDT Mon Aug 10 2026

Min RHs will be in the 25-35% range each afternoon into next week in the western Brush country and Rio Grande Plains. These low RHs combined with ERCs in the 70-89th percentile range will lead to elevated fire weather conditions over this region each day. Winds will generally be around 15 mph, with wind gusts in the 20-25 mph range. A few showers and storms are possible Sunday and Monday with mainly dry conditions the rest of the week.
