Saharan Dust, Gulf Humidity, Make for a Hot, Hazy and Humid Sunday

CORPUS CHRISTI, TX — In the wake of significant rainfall late last week, Saharan dust has arrived in the Coastal Bend. The dust has caused hazy skies, eye and lung irritation, and impeded rain chances. Nevertheless, a weak upper level disturbance is producing isolated elevated showers, mostly not reaching the ground. In the coming days, heat indices of between 105 and 109 will dominate your afternoons, along with gusty onshore winds that will reach 30 mph at times. High pressure in the upper atmosphere will move from the western Gulf of Mexico through South Texas by midweek, raising afternoon temperatures into the middle to upper 90s in the interior and around 93 in Corpus Christi by Wednesday. That system shifts into the High Plains by late week, easing daytime heating a bit. Still, no significant rainfall is expected through the week.
