Another Scorching Weekend, Midweek Pattern Shift Toward Rain?

Relentless heat and humidity continues to turn South Texas into a steam room, with upper level ridging trapping heat and humidity like a pressure cooker through the first of next week. The dominant upper level high pressure area then shifts to the Arizona-New Mexico border midweek, allowing a series of potent disturbances to glide down the Rockies and destabilize our air mass. That means an increasing opportunity for rain and thunderstorms, especially Wednesday through Friday (and, actually, into next Saturday). With a weak cold front that arrives in the area Tuesday night becoming stationary over the region, it will provide a low level focus on which the upper air pattern will generate rounds of showers and thunderstorms. This is a typical late summer pattern, and we should hope it will come to fruition.
