HOUSTON — After a stretch of pleasant fall weather, Southeast Texas is heading into a big pattern change this weekend. The stormy El Niño pattern expected for fall, winter and spring is starting to take shape. Street flooding is possible anywhere in Southeast Texas on Sunday, and severe storms are possible south of Interstate 10.
One More Beautiful Day Before the Change
Friday will be the pick of the weekend, with sunshine and a high near 80 degrees in Houston. Mornings will stay cool, with lows near 51 degrees and a light northeast wind around 10 mph. Residents should enjoy the calm conditions while they last, because the pattern will turn quickly.
On Saturday, clouds return as moisture starts moving back into the region. Highs will reach only about 68 degrees, with a low near 50 degrees and a breezy east wind around 20 mph. Rain chances stay low at about 10 percent, giving residents a last chance to prepare before the storms.
Sunday Brings Widespread Storms
Sunday is the day to watch. Houston’s rain chance climbs to 80 percent, and thunderstorms are likely. Highs will hold near 66 degrees, with a low around 53 degrees and gusty southeast winds near 25 mph. Steady, heavy rain could make roads dangerous for much of the day.
Forecast models show a broad area of moderate to heavy rain over the Houston area by Sunday afternoon around 3 p.m. Intense bands are expected along the coast from Corpus Christi northeast toward Houston, with heavy rain also spreading east of San Antonio and Austin. Rain will also reach toward Dallas and into Louisiana as the system moves east.
Street Flooding Risk Across Southeast Texas
The biggest concern is street flooding, which could happen anywhere in Southeast Texas on Sunday. Heavy downpours falling over short periods can quickly overwhelm drainage systems, especially in low-lying neighborhoods and underpasses. Areas that often flood during heavy rain should be watched closely…
