The KHOU 11 Weather Team issues a Weather Impact Alert for Monday due to potential isolated tornadoes and damaging winds affecting holiday travel.
HOUSTON — The KHOU 11 Weather Team has issued a Weather Impact Alert for Monday as strong to severe storms are expected late tonight. The setup brings the risk of damaging wind, an isolated tornado, and isolated hail, with the highest impacts expected during the late-evening and overnight hours.
Most of Monday will stay warm and humid with only a few isolated showers. However, storm chances rise sharply after sunset as a powerful line of storms pushes into Southeast Texas.
Active weather alerts
- The National Weather Service has issued a Tornado Warning for northeastern Austin County and central Waller County until noon. At 1126 a.m., a severe thunderstorm capable of producing a tornado was located near San Felipe, or near Sealy, moving northeast at 20 mph.
Timing: When storms are most likely
Storms may arrive in several waves. Light rain or isolated thunderstorms are possible through early afternoon, followed by scattered storms between 1 p.m. and 5 p.m. The main line of storms is expected to reach the College Station area between 6 p.m. and 8 p.m., then move toward metro Houston between roughly 10 p.m. and 2 a.m. After 2 a.m., storms should push toward the coast, clearing the region completely around sunrise Tuesday.
Tonight’s storms may interfere with both road travel and air travel during one of the busiest holiday rush periods of the year.
Threats to watch for
All severe components are possible while the line is mature: damaging wind gusts, an isolated tornado, and isolated hail.
The Storm Prediction Center has placed much of the region under a Level 2 severe weather risk, including Houston. The line is expected to weaken as it moves toward the coast, but residents along the entire route should stay alert.
Areas most at risk
Northern cities and counties are expected to see storms first — including Huntsville, Livingston, Cleveland, Brenham, and Spring — before the line reaches the Houston metro late tonight. Coastal locations are likely to see the storms last, between roughly 2 a.m. and 5 a.m.
How to prepare
- Reschedule late-night plans
- Secure outdoor holiday décor before bed
- Keep phones charged and alerts on
- Avoid driving during the strongest storms if possible
No flooding concerns are expected because the line will move quickly.
After the storms, cooler air arrives for Thanksgiving
Storms should clear early Tuesday morning, leaving behind cooler and drier air for the rest of the week. Thanksgiving is expected to be sunny and cool with a high near 68°, with temperatures in the 40s for early-morning Turkey Trot events. Calm and pleasant weather is expected Friday before the next rain chance returns this weekend.
