KEY MESSAGES

Issued at 131 AM CDT Thu Aug 6 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.

DISCUSSION

Issued at 131 AM CDT Thu Aug 6 2026

Mid-level ridging will continue to be the main driver of our forecast for the upcoming period. While a Four-Corners ridge remains generally stationary, the Bermuda high will gradually stretch eastward across Florida. A weak wave looks to ride below the southern edge of the Bermuda high toward the weekend and makes its way toward the Texas coast. Moisture appears limited - so no substantial rain chances expected. Will maintain some 10-20% rain chances with the seabreeze daily through the end of the week. For the weekend could see slightly higher (20-25%) PoPs around the Victoria Crossroads.

Temperatures remain near seasonal normals through the period with highs between 100 and 105 west and in the mid and upper 90s east. Heat index values will top out primarily between 105 and 110. Low temperatures will be mainly in the 70s. RH values do fall to near low levels west, however fuel moisture are normal and should limit elevated fire weather concerns.

AVIATION

(06Z TAFS) Issued at 131 AM CDT Thu Aug 6 2026

VFR conditions persist for the majority of the TAF period, with the exception of 08Z-12Z where all terminals have brief periods of MVFR CIGs and/or VIS. Upon mixing of the boundary layer after 12Z, southeast winds pick up to 10-20 kts sustained through 04Z and relaxing to 10 kts or lighter by the end of the TAF period.

MARINE

Issued at 131 AM CDT Thu Aug 6 2026

A gentle to moderate onshore flow can be expected through the forecast period, occasionally fresh 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 under 20% through the weekend.

FIRE WEATHER

Issued at 131 AM CDT Thu Aug 6 2026

Min RHs will generally drop into 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 55-75th percentile range will support localized elevated fire weather conditions over this region each day, however fuel moisture are generally near normal, thus any elevated conditions should be limited. Winds will gradually increase out of the E-SE in the 12 to 18 kt range during the afternoons. Daily rain chances will generally be 10% or less.
