Tropical Showers Douse Coastal Bend

CORPUS CHRISTI, TX — In the wake of several unusually arid days over the Coastal Bend, deep layered tropical moisture returned today and delivered plentiful rains to portions of the region. Rain chances will taper off Tuesday, be generally absent through the rest of the work week, then return for the weekend. Rain chances are largely dependent upon the positioning of the upper level ridge, which either can enable or preclude shower and thunderstorm development. As that ridge moved north Sunday, Gulf humidity returned in abundance along with weak mid level instability. That allowed showers and a few thunderstorms to sweep into the Coastal Bend. The upper ridge will stay north of the area Tuesday but return mid- to late-week and seal off rain chances. The core of the upper level high pressure shifts into the Great Basin over the weekend, opening the door for more tropical downpour for South Texas. High will remain in the upper 80s to around 90, with lows in the middle 70s.
