Houston is in for another middle-of-the-night wake-up call as a round of heavy rain, gusty wind and thunderstorms is expected to move through Southeast Texas overnight into Wednesday morning.
Current timing brings storms moving through the Houston metro area around 2 to 3 a.m., then shifting east by around 5 a.m. There is the potential for another round of storms between 9 a.m. and 11 a.m.
The timing is especially important because the strongest activity is expected to overlap with the Wednesday morning commute. Drivers should be prepared for reduced visibility, ponding on roads, and occasional slowdowns where heavier downpours develop.

Wednesday’s Storm threats - street flooding and damaging wind gusts:
From the image below you can see a squall line moving through Houston at 3am. Along this leading edge there could be damaging wind gusts ranging from 50-60 mph.
Beyond the threat of strong winds, street flooding is another key concern for Wednesday morning. After several days of soaking rain, ground conditions are already saturated. That means it won’t take 4 or even 6 inches of rain to trigger flooding, just an inch or two could cause water to collect on roads quickly.
Runoff will occur faster than usual, creating a higher-than-normal chance for street flooding across much of the Houston area and Southeast Texas. There is a widespread risk, so try and be flexible for the ride to work and never drive through flooded streets.
The possibility of a second line of storms:
What is new from the latest data is there may be a second round of storms moving through southeast Texas between 9:00 and 11:00 am. This line will not bring strong winds but it will add to the rain totals if it does occur.
Rain totals:
There is a street flooding threat Wednesday morning. Below are possible rain totals.
Quieter weather pattern on the way:
Once we get through Wednesday, we’ll get a break from the widespread heavy rain and organized storm threats. Rain chances lower to 20% Thursday and Friday with Saturday looking completely dry. There is more rain possible next week as we start the month of June.
And speaking of June, hurricane season officially begins next week on June 1st.
