High atmospheric pressure has finally arrived in the Lone Star State — and for once, that’s actually good news. High pressure leads to sinking air, which suppresses the development of showers and thunderstorms. After the widespread flooding across Texas during the first half of July, this ceiling of high pressure will allow a much-needed break from daily rain chances.
That is, except for one section of Texas. The National Hurricane Center is monitoring a low pressure system located along the northern coast of the Gulf of Mexico. This system has a chance to develop into a tropical depression within the next 24 hours. Even if it doesn’t, it’s still expected to bring heavy rainfall and a flooding threat to far East Texas. Here’s what you can expect.
San Antonio Thursday forecast
Across South-Central Texas, slightly drier air is in place, which will allow morning temperatures to drop a couple of degrees from what we’ve gotten used to lately. San Antonio can expect predawn low temps to be around 73 degrees, while many in the Hill Country will experience temperatures in the upper 60s from 6 to 8:30 a.m.
Temperatures will rise steadily throughout the day, reaching the 90-degree mark just after 1 p.m. San Antonio can expect partly to mostly sunny skies, before eventually hitting a high temp of around 95 degrees, which would be average for this time of the year.
We have virtually no chance of rain across the San Antonio metro area, Interstate 35 corridor or across the Hill Country.
Tropical rain for East Texas
By Thursday evening, especially after 7 p.m., a plume of tropical moisture is expected to move into Southeast Texas…
