Severe Thunderstorm Watch issued until 1pm Tuesday afternoon
More thunderstorms are expected to develop Tuesday morning as a cold front sags to the south
BRYAN, Texas (KBTX) - Better feeling air is on the way! This after the first 90° day of 2021 officially checked in at Easterwood Airport for Bryan-College Station. Summer-like highs and heat index values near 100° will be swept away as a cold front moves through the area between 4am and noon Tuesday.
Before that comfortable air arrives...storms are expected for some Tuesday morning.
9:30am Tuesday Update
As a cold front moves south through the area Tuesday, a few severe thunderstorms have been trekking through the Brazos Valley this morning, mainly with a strong wind/hail threat.
A SEVERE THUNDERSTORM WATCH is in effect for the following counties until 1pm Tuesday:
Brazos • Burleson • Madison • Houston • Trinity • Grimes • Walker • San Jacinto • Montgomery • Waller • Austin • Washington
We’ll continue to watch storms moving into the area for hail up to the size of quarters or larger and wind gusts in excess of 60 mph+ through the first half of Tuesday.

11pm Monday Update
A SEVERE THUNDERSTORM WATCH is in effect for the following counties until 3am Tuesday:
• Milam • Robertson • Leon
These counties are included as the southernmost fringe of the watch that extends into North Texas. As of the hour, there was an isolated severe storm located 10-15 miles north of Bremond, with reported golf ball size hail. This storm was drifting east and -- as of this update -- anticipated to remain just north of the Brazos Valley.
That should be the trend with activity through the overnight. While these counties are included in the watch, the overall, overnight concern remains low at this time.
First crack at rain and a few rumbles of thunder could come as early as 3am to 5am across Robertson, Leon, and Northern Houston County. This round of rain and rumbles is not ascertain, but certainly not ruled out before sunrise. While the overall severe weather risk is low, small hail and gusty wind could accompany brief, heavy downpours and occasional lightning.
SHOULD STORM BECOME STRONG OR SEVERE TUESDAY MORNING, the following will be possible:
- Wind Gusts 40mph+
- Pocket-change size hail, generally smaller than a quarter
- Heavy rain upwards of 3/4″
- Frequent lightning
More likely, as the sun comes up, areas of thunderstorms will have the ability to spark up on the north wind shift steadily moving south across the Northern and Central Brazos Valley. Any initial thunderstorms that develop between 7 am and 10 am, could briefly become strong or even severe. Strong wind gusts and small hail would be the greatest, more thought of concern. Considering this activity could develop at the morning drivetime, heavy rain may reduce visibility and pond water on roads. Lightning may also be an issue for students waiting for a bus or arriving at area schools.
The low-end severe weather concern becomes even lower between 9am and 11am as leftover, scattered rain and a few rumbles drift east of I-45 and ultimately out of the Brazos Valley. Only a small chance for rain redevelopment is expected between noon and 4pm.
Once the storm chance passes and the cold front moves south of the Brazos Valley, lower humidity and mild air return on a breezy north wind. Highs are expected to run 10°+ cooler than Monday. Thermometers are only expected to reach the upper 70s to about 80° Tuesday afternoon.
