BRYAN, Texas (KBTX) - A TORNADO WATCH is in effect until 8pm for the following counties:

• Austin • Burleson • Brazos • Grimes • Houston • Madison • Montgomery • San Jacinto • Trinity • Waller • Walker • Washington

7pm Update

The Severe Thunderstorm Watch has been canceled for Milam, Robertson, Lee, and Leon Counties. As of the hour, the tornado watch remains in effect, although the overall threat of severe weather has come to an end.

The dryline has managed to spark up strong thunderstorms west of I-35 through North and Central Texas, along San Antonio into South Texas. These will need to be monitored this evening for possible, isolated activity after midnight (low confidence).

This will be the last update for this story. More details can be found on the weather page here at

A SEVERE THUNDERSTORM WATCH has been issued until 8:00 pm for the following counties:

• Milam • Robertson • Leon (Lee County removed as of 4pm)

As thunderstorms develop through the afternoon, the strongest activity will be capable of large hail and strong wind gusts. In the most extreme case, that hail size could grow upwards of golfball to egg size, along with winds in excess of 70mph. While not the main concern for the day, any intense thunderstorm could also create a tornado concern at times.

Storm activity through the day is expected to come in two waves:

  • through 5 or 6pm: Isolated storm concern. This is where the most intense thunderstorm development may occur, with the occasional large hail threat. Any storm in the Brazos Valley is expected to move through at 30 to 40mph.
  • 7pm - 9 or 10pm: A broken line of thunderstorms will be possible, moving from west to east. This activity is contingent on what forms west of the area, generally near or along I-35 through the afternoon hours. Should a segment of this line be severe, strong wind 50mph+ would be the main concern.
