Hourly and special weather reports are available as METAR text data from ASOS equipment owned and maintained by the NWS/FAA/DoD or third-party AWOS equipment owned and maintained by the FAA, DoD, TxDOT, and local public/private organizations at airports across the region. While ASOS equipment has a standard configuration, AWOS equipment has a wide variety of sensor options. Most of the airport weather stations can be found on the FAA map of station configurations.
The NWS Austin/San Antonio WFO (EWX) in New Braunfels, TX is responsible for the Terminal Aerodrome Forecasts (TAFs) at four local airports in South Central Texas. These routine forecasts are issued by 00Z, 06Z, 12Z, and 18Z, with amendments as needed*. See map of local TAFs.
*As of April 15, 2023, both the Austin Bergstrom International (AUS) and San Antonio International (SAT) TAFs receive regularly scheduled amendments at 03Z, 09Z, 15Z, and 21Z due to the increasing traffic at these airports.
Austin/San Antonio WFO (EWX) also issues an Airport Weather Warning (AWW) at Austin Bergstrom International (AUS) or San Antonio International (SAT) when ground weather conditions warrant, such as lightning in the vicinity.

The Fort Worth WFO (FWD) creates soaring forecasts for locations across the state that launch daily weather balloons. For South-Central Texas, this includes Del Rio, and the soaring forecast can be found at the bottom of this page.
To better meet the demands of glider pilots across all of South-Central Texas, we are experimentally using data from the North American Mesoscale (NAM) model to generate similar forecasts for the Austin and San Antonio areas. A benefit to this is that we can create forecasts for both the current day and the next day since we have data into the future. However, since this data is coming from just one model and is not based on actual conditions, the forecast will inherently be less accurate. We also want to caution that these forecasts are not routinely monitored or quality controlled. These experimental forecasts can be found at the links below and are best viewed on a laptop or desktop computer:
For more information on what soaring forecasts are and how they are created, please see this website created by our colleagues in Spokane, WA.
The NWS Houston CWSU (ZHU) at the FAA Air Route Traffic Control Center (ARTCC) in Houston, TX is responsible for aviation weather forecasts for the airspace above South Texas, southern Louisiana, southern Mississippi, Southwest Alabama and the northwest Gulf of America.
The NWS Aviation Weather Center (AWC) in Kansas City, MO produces national forecasts such as AIRMETs and SIGMETs for the CONUS.
