KEY MESSAGES

Issued at 601 AM CDT Sun Aug 9 2026

- Moderate to major risk of heat-related impacts next week, with peak heat indices 110 to 115.

- A low chance (20-30%) of showers and storms Sunday into Monday.

DISCUSSION

Issued at 124 AM CDT Sun Aug 9 2026

For the remainder of the weekend and into early next week we remain in a weakness between high pressure to the northwest and high pressure to the east. With this we will keep a low chance of rain as bits of energy and some elevated moisture work toward the Texas coast. Mainly we're looking at a few sea breeze showers and storms, but some morning convection will also be possible along the coast within some marginal instability. Beyond Monday the ridge to the northwest begins to collapse and the ridge east shifts move over the region limiting rain chances for the rest of the week.

Temperatures remain generally around seasonal averages, but will range from a degree or two below normal Sunday to a few degrees above normal by late in the work week. Heat index values increase for the latter half of the period and heat advisories may become necessary by mid-week.

AVIATION

(12Z TAFS) Issued at 601 AM CDT Sun Aug 9 2026

Showers from the western Gulf are moving onshore. While these showers will weaken as they move onshore, the strongest showers/storms may briefly reduce VIS to MVFR conditions, but mostly remain isolated in nature. This afternoon, this shower activity and seabreeze moves inland. Confidence is low with respect to how far inland these will move, but we will continue to monitor the trend for KLRD for the upcoming TAF cycle.

MARINE

Issued at 124 AM CDT Sun Aug 9 2026

Light to moderate onshore breezes Sunday and Monday will increase to a more moderate breeze, with periods of fresh breezes, Tuesday through the end of the week. A low to medium (20-40%) chance of showers and thunderstorms will continue Sunday and Monday with mainly dry conditions thereafter.

FIRE WEATHER

Issued at 124 AM CDT Sun Aug 9 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.
