While the steady rain has stopped, the atmosphere above South Texas is still packed with plenty of atmospheric moisture. So far, it has resulted in mostly cloudy skies and very humid conditions throughout the region.
That humidity will continue Friday and into the weekend, which could allow for humidity-driven heat index values to rise to nearly 100 degrees by Sunday. Before that, however, the elevated moisture is likely to result in a few isolated, strong thunderstorms. While coverage of these storms will be limited (keeping most areas dry), a few storms could be severe, capable of producing hail and damaging wind gusts.

Cloudy skies are expected during the parade, with just a 10-20% chance of an isolated shower or storm. Temperatures will rise to around 80 degrees by 1-2 p.m…
