TIMELINE: Stormy weather, heavy rains expected in Houston through Memorial Day weekend

Street flooding is possible as well as severe storms that could bring hail, wind gusts

Get ready for a chance for substantial wet weather as we head into the official kick off of summer this weekend. A series of storm systems will move across Southeast Texas, bringing the potential for significant rainfall totals starting late Tuesday through the holiday weekend.

Our forecast indicates widespread amounts of 2 to 4 inches, with isolated areas north of I-10 potentially receiving over 7 inches. Because we expect multiple rounds of rain, the ground will become saturated quickly, increasing the risk for runoff and street flooding.

In addition to the heavy rain, some storms Thursday and Friday morning could be strong to severe, capable of producing hail and strong wind gusts. Please stay weather aware this week and ensure you have multiple ways to receive weather alerts. Our weather app is a great place to start.

Round #2 Thursday:

This is where the timing gets tough. Because we are tracking small areas of low pressure, called short waves, they usually don’t show up on our micro cast models until 24 hours out.

So, for now the general timing is Thursday morning into lunchtime. The important thing to keep in mind is we have another street flooding threat. This is because we have seen so much rain in some spots over the past 2 days, the ground has become saturated and cannot take much more rain before having some flooding issues.

Round #3 Friday:

Similar to Thursday the timing and placement of the storms is unknown. But with the pattern we have, another flood threat is with us. If we had to give you a time I’d say late morning to early afternoon. Please check back for updates to the timing.

Saturday through Memorial Day Monday:

There is a chance of storms and heavy rain every day through Memorial Day. In fact, we’ve had to move our rain chances up to between 60-70% so indoor plans are a safe bet for your weekend plans.

After Memorial Day we may be looking at rain totals for the entire 7-days ranging from 3″-7″!
