The risk of flooding in Houston on Labor Day has decreased following a weekend of heavy rain and thunderstorms. According to the National Weather Service, there is a 50% chance of rain after 10 a.m., with showers and thunderstorms potentially affecting outdoor activities around midday and into the afternoon. However, current conditions are less severe than those forecasted the previous day.
Labor Day showers are expected to be less widespread, with the flood threat level reduced from 2 out of 4 to 1 out of 4 compared to the previous day. Isolated showers may begin by mid-morning, with storm activity likely to peak during the warmest part of the day. Storm coverage is expected to increase near the coast by around 3 p.m. While some isolated storms may continue into the evening, they are expected to produce frequent lightning. Click2Houston reminds residents, “When thunder roars, head indoors!”
Looking ahead to the week, temperatures in Houston may begin to shift as the first full week of September is expected to bring below-average temperatures across much of the country. As reported by Click2Houston, while daytime highs will remain elevated, morning lows could drop into the low 70s following recent rainfall, which marks a change from the typical upper 70s for this time of year. Although summer conditions in Houston often extend into October, this week’s forecast may indicate an earlier temperature shift.
Regarding tropical weather, Click2Houston reports that "the tropics remain generally quiet," with only one disturbance off the coast of Africa showing a 30% chance of development over the next seven days. Currently, there are no tropical threats to the Gulf, which is unusual for late August. The upcoming days are expected to remain clear. For those seeking to stay prepared, a 2025 Hurricane and Flood Survival Guide is available.
After a stormy start to the week, conditions are forecasted to improve with a return to mostly sunny skies, daytime highs in the low 90s, and clear nights, according to the National Weather Service.
