KEY MESSAGES

Issued at 200 AM CDT Fri Aug 7 2026

- Moderate to major risk of heat-related impacts through the week, with peak heat indices 105 to 110, and high to extreme WBGT values.

- Low-end chances (20-40%) of rain this weekend with highest totals along the coast.

DISCUSSION

Issued at 200 AM CDT Fri Aug 7 2026

Mid-level high pressure will continue to dominate the period leading to warm and mostly rain free conditions outside of isolated seabreeze showers. Saturday looks to have the best chance of precipitation as mid-level vorticity riding the periphery of the ridge will make its way into South Texas at the same time that PWAT values approach 2.1" along the immediate coastline. However, QPF values from any sea breeze storm has lower confidence given the variation of the max PWATs. With the increased cloud cover over the weekend, heat index values will struggle to surpass the heat advisory threshold. However, areas that don't experience a sea breeze shower or significant cloud cover may experience heat index values over 110F. From the start of the workweek, near heat advisory conditions return with increasing confidence in the spatial coverage of 110F+ values and duration of the peak heat index values.

AVIATION

(06Z TAFS) Issued at 200 AM CDT Fri Aug 7 2026

VFR conditions can be expected through the period once again. Periods of MVFR cigs and VSBYs will be possible once again tomorrow morning at a couple eastern terminals (mainly ALI and VCT though not out of the question for CRP). Winds will be breezy out of the south until this evening before becoming generally light.

MARINE

Issued at 200 AM CDT Fri Aug 7 2026

Light to gentle onshore flow will be expected through the forecast period. Occasional periods of moderate winds can be observed along the nearshore waters and bays in the afternoon. Seas will generally range from 2-3 feet through the period. Daily rain chances will be remain under 20% through the forecast period with the exception of this weekend (30-60%).

FIRE WEATHER

Issued at 200 AM CDT Fri Aug 7 2026

Min RHs will be in the 25-35% range each afternoon through the weekend 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 sea breeze shower cannot be ruled out this weekend though wetting rain chances will remain low.
