A flooding threat in Houston begins Thursday with areas near and south of the city bracing for heavy rainfall. When will the worst weather arrive?

There’s a lot happening across the greater Houston area for Friday and some areas could be dealing with some hefty storms as the day wears on. Here’s a timeline on when to expect downpours as you head out! The first wave of heavier rain looks to fire up around noon with scattered pockets of downpours moving in from the southwest.

Unlike rain that comes from a cold front, this round of storms formed along an upper-level area of low pressure. The result is that we won't feel any cooler after the rain ends. Highs are likely to reach the mid 80s both Saturday and Sunday with heat index values that could reach 90.
