Next round of storms:

The flood watch has been expanded to cover the Hill Country and South Texas, marking a significant shift since this time yesterday. While the flood watch originally focused southwest of Houston, it now includes a much larger area and it may soon include the city itself, especially as the weekend weather pattern develops.

The flood watch remains in effect through Memorial Day on Monday. Some spots haven’t picked up much rain yet this week, but that doesn’t mean the risk is over. More storms are expected before the end of the holiday weekend, and areas north of Houston could start to see those higher totals soon.

Areas south of Houston have seen the most rain so far, anywhere from 5.5 to 7.5 inches in towns such as Angleton, Lake Jackson, Freeport, and Bay City. Houston itself has measured 1.5 to 2.5 inches, with less than a half inch in cities like Huntsville.

Friday and beyond: Flood risks and daily breakdown:

With the ground already saturated in our southwestern cities, street, stream and river flooding is possible with another round of heavy rain. Placement is key, and so far the Houston area’s rain totals have been manageable. But if too much rain falls in a short amount of time, we could get street flooding in the Houston area. Here’s how the next several days look.

  • Friday: Storms are much more hit and miss. The storms that develop will be strong but most of the day should be quiet.
  • Saturday and Sunday: More waves of heavy rainfall could develop, keeping the flood risk in play.
  • Memorial Day: Flood watch moves east. There will be storms, but the rain should be isolated.

Additional rainfall totals are forecast to reach 2 to 3 inches for many areas along the upper Texas coast through Monday. Temperatures are expected to stay mostly in the low to mid-80s. It won’t rain all day long so don’t cancel any plans but be ready to adjust those plans.

Memorial Day Weekend:

The number one question I’ve received about this upcoming weekend is timing of the rain. Unfortunately, the weather pattern we have isn’t giving us this luxury. We aren’t able to see these small disturbances until 12 to 24 hours before the rain starts. Stay tuned, we’ll continue to update our forecast and tell you as soon as we see what’s coming next.

7-Day Forecast:

This active pattern should stay with us through at least Tuesday. The hope is next week we head into a hit and miss afternoon storm pattern and not the widespread daily flood threat. We’ll keep you posted.
