Houston is staring down a noisy night, with meteorologists on Sunday warning that a round of overnight thunderstorms could rattle Southeast Texas in the early hours of Monday, May 11, 2026. A line of storms is expected to creep into the metro before dawn, packing heavy rain, frequent lightning and gusty winds strong enough to snap limbs and trigger pockets of street flooding. Anyone with early Monday plans is urged to track conditions and know exactly where they will go if the sky turns ugly.
FOX 26 Houston highlighted the threat in a short video posted May 10, urging viewers to keep an eye on live radar and be ready to head indoors quickly if storms develop stronger wind cores or intense downpours.
A federal forecast backs up the concern. A corridor of deep Gulf moisture colliding with a slow front could set up training thunderstorms with high rainfall rates, according to the Weather Prediction Center's Excessive Rainfall outlook. That outlook calls out parts of the Gulf Coast, including the Houston area, for the risk of localized hefty totals that might briefly overwhelm urban drainage if storms keep tracking over the same spots.
What to expect before dawn
According to the National Weather Service in Houston/Galveston, the main concerns with any stronger storms are damaging wind gusts, isolated hail, frequent lightning and bursts of intense rain that could quickly cut visibility and send water surging through low‑lying creeks and bayous. Watches or warnings may be issued if storms organize or begin repeatedly targeting the same neighborhoods.
How to prepare
Before heading to bed, secure loose outdoor items, top off your phone battery and keep a battery‑powered radio or weather app handy in case electricity or cell service takes a hit. Local forecasters, including Space City Weather, advise giving yourself extra time for the Monday commute, steering clear of flooded streets and moving to shelter right away if you hear thunder or see lightning.
This story will be updated as the forecast shifts and if any watches or warnings are issued. For the latest official information, follow the National Weather Service in Houston/Galveston and your preferred local station.
