Weather Timeline

WEDNESDAY: The morning commute will be wet. Expect a washout with the possibility of street flooding. Rain chances stand at 100 percent as very deep tropical moisture associated with Invest 91-L moves through the area. 

The National Weather Service is saying that rainfall rates will be approaching 3 inches per hour with as much as 6 inches in a four-hour window. If those rain rates are realized and come to fruition, widespread street flooding will be an issue.

We know everybody wants to know exactly how much rain they can expect in their town or neighborhood but that’s impossible. Just know that widespread 2-4 inches of rain is expected with isolated pockets considerably higher. Some models are even advertising as much as 8 to 10 inches. 

The good news here is that the storm speeds should be fast — meaning they won’t be sitting over any one area for too long. Unfortunately, as with any tropical disturbance, the rain pushes through band after band after band. So while the storms themselves will be moving fast, they’ll be replaced by more rain as the feederbands continue to stream through.

Aside from the heavy rain, we’ll have to watch for the possibility of funnel clouds and quick, weak tornadoes although severe weather is not expected to be a big problem. 

THURSDAY: Rain chance decreases after the early-morning hours — after 4 a.m. — but scattered showers will linger into the mid-morning hours. Drier conditions after lunchtime as the center of circulation pushes through.

7-day forecast

FRIDAY: 20-percent rain chance remains as the temperatures begin to soar. Expect temps back into the low 90s with feels-like numbers approaching 100°F.

THIS WEEKEND: Mostly sunny- hottest temperatures of the year so far, topping out in the mid- to upper-90s. Feels-like numbers could top 105°F or higher. You’ll certainly want to practice heat safety which means drinking lots of water, staying in the shade and wearing light colored clothing.

Come on Houston, we know how to ‘Summer’ around here. Be smart and take care of yourself. You don’t need me preaching to ya!
