Relentless Heat and Humidity Next Several Days; Rain Chances Next Week?

A powerful upper level ridge will dominate South Texas through the weekend and into the first of next week, bringing dangerous heat and humidity with marginal overnight relief and no rainfall. Afternoons will be sweltering, with air temperatures from the upper 90s to lower 100s and heat indices of 105 to 110. The upper ridge finally begins to break down by late Tuesday and Wednesday, allowing a weak disturbance to bring isolated to scattered showers and thunderstorms to the region.
