After several weeks of active weather across South and Central Texas, the pattern is undergoing a major shift this week. A summerlike high-pressure system is building across the state, and it is expected to remain in place through much of the week.
That will bring lower rain chances, hotter temperatures, and oppressive humidity levels. San Antonio may even see “feels-like” temperatures rise to around 103 degrees by the end of the week. However, weather models are already showing when high pressure will weaken and thunderstorms may return to the forecast.
Monday’s forecast
It will be a very muggy and mild morning across the San Antonio metro area as low temperatures are expected to hover near 77 degrees under partly to mostly cloudy skies. A few areas of patchy fog are also possible between 4 and 8 a.m., but widespread visibility issues are not anticipated.
By midday, skies should become partly sunny, allowing temperatures to climb into the upper 80s to near 90 degrees. Humidity will remain extremely high, pushing “feels-like” temperatures close to 100 degrees by late afternoon.
Due to these high atmospheric moisture levels, there will also be a slight chance of a few pop-up showers and storms, mainly between noon and 4 p.m. Overall rain chances will only be 20% to 30%, so many areas across South-Central will stay dry…
