With all the heat last week, it seemed inevitable that Houston was due for a change. With scattered heavy rain across the entire area since Thursday, that change has certainly come and it promises to continue right into Saturday. In fact, the National Weather Service is predicting as much as two to four inches of rain north of Houston and one to two inches from Houston to the coastline by Saturday morning.
The combination of instability in the atmosphere, tropical moisture and high summer temperatures is combining to produce conditions ripe for rain include some potential flash flooding and generally gross conditions through Saturday.
The rain should begin to taper by Saturday afternoon and we'll be left with scattered though sometimes heavy rain showers, about like what we've had most of this week. By next week, most of our rain chances will subside and we'll fall back into typical Houston summer patterns with highs in the mid 90s and a 20-30 percent chance of scattered showers and thunderstorms.
If you don't have your umbrella with you today, you might consider grabbing one while you're out because it should be pretty damp across the entire area.
