(00:00:00) Todays weather in Houston Texas - Wednesday - 20 May 2026 (00:00:27) Severe Storm Risk Tonight (00:01:01) Flood Advisory Risk Building (00:01:24) Wednesday Morning Commute Warning (00:02:01) Week-Long Wet Pattern Ahead (00:02:23) Houston Evening Send-Off Houston's evening commute is in the crosshairs tonight. A cluster of thunderstorms is pushing in this afternoon and into the night, bringing 1 to 3 inches of rainfall city-wide and 4 to 6 inches possible north of I-10. That's street-flooding territory — and the timing lands squarely on top of rush hour.These aren't ordinary Houston thunderstorms. Some cells could turn severe, carrying damaging winds and hail. The exact arrival window is still uncertain, so don't assume you've missed it on your way home. Give yourself extra time, pull over if visibility drops, and never drive through standing water.Flood conditions are building. The ground is already saturated, making tonight's rain more dangerous than the totals alone suggest. A Stage One flood advisory is a real possibility as the week stacks up. More critically, a Storm Alert has already been issued for Wednesday morning — heavy rainfall is expected during the morning commute, and conditions could be worse than tonight. Start identifying alternate routes now if your usual path includes low-lying streets or underpasses.Temperatures hold in the low-to-mid 80s through midweek — warm but stormy and humid. Waterproof shoes, an umbrella, and light layers are non-negotiables all week.

There is no clear break in the short-term forecast.Stay weather-aware, leave early, and skip that underpass.This episode includes AI-generated content.
