SAN ANTONIO – (UPDATE 2:45 p.m.): This morning’s heavy rain has diminished however, additional development is underway in the Hill Country. Downpours are showing up on radar from Rocksprings to Kerrville to Fredericksburg. This activity will continue to move south, producing brief, heavy rain and wind gusts up to 40 mph. While it is fairly stable over San Antonio right now, these downpours may make their way closer to town later this afternoon and this evening. Any areas that received heavy rainfall this morning will need to be watched for possible flooding. The best chance for rain will shift south of I-10 and Highway 90 tomorrow.


(UPDATE: 7:40 a.m.): Rounds of heavy rain have made their way through the area this morning and Flash Flood Warnings remain in place for parts of Comal, Guadalupe, and Hays County.

In the meantime, another area of heavy rain is currently moving into west and northwestern Bexar County. This will likely lead to some street flooding, as it moves east across the city. You can also expect these storms to be fairly electrical. Once this cluster of storms passes through, we should see a break in the action. However, there is a potential for additional storms to develop later this afternoon and evening.


(UPDATE 6:30 a.m.): A front lying across the area is bringing some very unusual weather to the start of August, KSAT Meteorologist Mike Osterhage said.

Showers and storms with very heavy downpours have been continuing to develop this morning. 2 to 4 inches of rain has fallen in a very short time, prompting numerous flood warnings and advisories. More storms will dump heavy rain on saturated ground, continuing the flooding threat, Osterhage said.

Also, temperatures today will only be in the upper 80s, about 10 degrees below what we’d normally see in the first week of August.

Rain chances will stick around most of the week, although not as widespread. Temperatures will remain well below normal this week. This weekend, we’ll be back to sunny, hot, and humid summer weather, Osterhage said.


(Original Story)

After some torrential downpours and a few strong storms on Sunday, rain chances will carry over into the start of the workweek. Here’s what you need to know:

  • A weak front will slowly move across South Central Texas on Monday, acting as a trigger for more rain to develop
  • Any storms on Monday could be on the strong side, with very heavy rain leading to flooding being the main concern; some storms may also produce strong wind gusts & frequent lightning
  • The front will sag south of San Antonio on Tuesday, taking the focus for heavy rain south of Highway 90
  • Rain chances are expected to become more isolated by midweek
