Dangerous Heat Persists in San Antonio, Relief Expected Thursday
The National Weather Service (NWS) has issued a heat advisory for San Antonio and surrounding areas along the I-35 corridor, including the coastal plains to the east. The advisory is in effect from noon to 7 p.m. on Monday, with additional advisories likely for Tuesday, Wednesday, and Thursday. High temperatures are expected to reach 100°F (37.8°C) throughout the week, with heat indices climbing as high as 111°F (43.9°C) due to high humidity. An upper-level ridge over northeast Texas is contributing to the hot and dry conditions, blocking rain development. However, forecasters predict a slight chance of showers on Thursday and Friday, which could bring some relief as temperatures dip into the mid-90s (around 35°C). Fall officially begins next Tuesday, but cooler temperatures are not expected until late October.
