Issued at 131am CDT Thu August 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%) Probability of Precipitation 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.

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 131am CDT Thu August 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.
