HOUSTON – Watch for flooding late week as scattered to widespread rain moves through Thursday through Friday.
Thursday’s Flood Risk (1 out of 4):
Thursday’s flood risk is focused is mainly north of I-10.
Friday, the flood risk increases and includes all counties in southeast Texas. More waves of rain and storms move in along a slow-moving cold front. Watch for street flooding and ponding, and give yourself extra time for morning and evening commutes.
Flooding is the main concern as some areas could pick up to 3 inches of rain. Strong to severe storms are expected to develop on Friday, producing strong winds and hail. Thankfully, the risk is marginal.
If you look down at the list, a marginal risk generally means short-lived but intense storms, but isolated coverage.
Now let’s talk about timing:
There will be non-severe storms and scattered rain starting as early as 8 AM and moving north through the afternoon.
The rain chance winds down briefly before more waves of rain return late Thursday night into Friday.
By the evening, Houston sees a slight lull before more rain and storm activity fires overnight into Friday. By Friday morning, widespread rain continues, but notice some bright purple and black colors in the middle of some storms on the maps below. Those are the clusters that likely will have a lot of lightning and hail if it forms. Some of the hail could turn severe, reaching a quarter-size or larger.
Friday afternoon storm continue but focused north of I-10.
