WEATHER RADAR: Track storms, rain across Southeast Texas
The forecast is constantly changing, however, so we will continue to update this timeline as we learn more.
Timeline: When to expect the heaviest rain, storms in Houston
THURSDAY PM: The rain chance increases overnight, especially in our northwest counties.
FRIDAY AM: The rain chance really picks up with heavy downpours likely before you wake up and through the morning rush hour commute. Expect slippery roadways and thunderstorms.
FRIDAY PM: Rain chances decrease a little as we head into the late afternoon and evening hours on Friday, but scattered showers are still possible overnight into Saturday.
SATURDAY AND SUNDAY: We’re looking at continuing widespread showers with a 60% rain chance. While it may not be as heavy as Friday morning’s rainfall, now is when we will want to keep an eye out for ponding on the roadways and isolated high water spots as the grounds will be very saturated by this point. It’s too soon to know for sure or know which areas will be the most impacted by flooding, if any.
You can see in this image below most areas can expect to get about 3 to 4 inches of rain now through Sunday night with the heaviest rainfall reported in Houston proper and areas to the southwest through Sugar Land and Wharton.
NEXT WEEK: Light scattered showers continue Monday and Tuesday — we won’t have a really nice, sunny day again until Wednesday.
