CORPUS CHRISTI, Texas — Our big heat dome of high-pressure will hold on to our weather pattern for a couple more days and deliver some sweltering temperatures to South Texas.

With the exception of a few clouds here and there, afternoon high temperatures will climb to the middle to upper 90s for many coastal locations and some low 100s for our inland communities.

In addition, there is deepening low pressure headed in our direction from the Central Plains and that is going to kick up our winds and humidity.

For today and tomorrow, heat indices will shoot around 103°-115°. Residents are encouraged to drink lots of water when outdoors and take frequent breaks if working. Seek the shaded spots frequently. Also, there is a Coastal Flood Advisory posted from 9AM-7PM today. Water may reach up to dunes and access roads, especially during times of high tide. For Bob Hall Pier and Port Aransas jetties, that will occur this morning between 10:15-10:35AM.

As our heat dome breaks down and gets shoved to our south, a weak area of low pressure will destabilize our atmosphere as it moves into north Texas. That will be enough to send a weak front into the area and stall for a couple of days and start rain chances late Sunday and last through the middle of next week.

Rainfall activity will be isolated in nature Sunday and Monday and more scattered with a few thunderstorms Tuesday and Wednesday. Though rainfall accumulation totals will be much higher to our north, some locations could pick up around a half inch of rain. Given the isolated and scattered nature of the rain, some locations will receive far less. We’ll monitor it closely.
