Update 7:30 p.m. Wednesday:

As if the heavy rain and flooding weren't enough, a sanitary sewer system on University Drive near I-30 in Fort Worth, about a mile away from TCU's campus, has overflowed into the street.

"Heavy rains entering Fort Worth’s wastewater collection system caused discharges citywide Wednesday," a statement from the City of Fort Worth read.

Update 6 p.m. Wednesday: Rounds of rain continue to affect the evening commute home. The heaviest of the rain is now southeast of DFW. Areas west of Fort Worth are beginning to dry out. Expect this wet weather to taper off west to east over the next few hours. After 9 p.m. most of the activity will be east of the immediate DFW area. Again, the severe risk is extremely low with flooding being our main concern through tonight. Flash Flood Watch is in effect through midnight.

Update 4 p.m. Wednesday: Our next batch of rain has started to spread across North Texas. The heaviest of the rain is falling south of DFW with embedded thunderstorms as well. Rounds of heavy rain will affect most everyone's evening commute. The severe risk is very low for DFW. Our main concern continues to be flooding due to our impressive 24-hour rainfall totals. The rain should start to taper off and move east by 9 p.m. All of North Texas dries out after midnight, setting up for a much better morning commute on Thursday!

Update 12 p.m. Wednesday: Much of North Texas is seeing a brief break in the heavy rain. However, another batch of showers and storms is filling in to the southwest of us. That means more rain as we head into the afternoon and evening hours. This cluster will move in our direction, affecting North Texas around rush hour. It's going to be a messy, slow-moving evening commute home. Additional heavy rain will likely lead to more flooding issues. The Flash Flood Watch stays in effect through tonight. Govern yourselves accordingly!

Update 10 a.m. Wednesday: Heavy rain overnight has led to numerous problems on the roadways this morning. Though we expect to see a small break now through midday, another heavy round of rain is expected later this afternoon and evening. The severe risk is very low for North Texas. Our main concern will be flooding due to additional rainfall on top of these impressive 24-hour totals.

WATCH: DFW flooding

Update 8 a.m. Wednesday: Rounds of showers and storms will continue Wednesday. It will not rain 100 percent of the day, but it will likely rain more often than not.

Last night's widespread rain is moving east and northeast out of the DFW area, but more rain is on the way. This round may be more hit or miss or scattered, but most places will see rain through the morning. Another round of widespread, heavier rain is possible this afternoon into this evening before tapering off this evening into Wednesday night.

WEDNESDAY

The severe weather threat on Wednesday is low once again for North Texas. Can't rule out a storm or two with wind/hail, but the main concern will shift to heavy rain and localized flooding. Rounds of showers and storms starting tonight through the day on Wednesday will contribute to rain totals of 2 inches to 4 inches being common across North Texas. Isolated amounts of 5 inches to 6 inches will be possible. This is enough to cause localized flooding in some locations. Remember to not drive into or through flooded roadways!

THURSDAY

As the storm system exits, wrap-around or lingering showers will be possible mainly during the morning hours. Highest coverage will be across the eastern half of North Texas. Most rain will be on the light side with no severe weather expected.

Showers or storms will continue to move east with clearing skies. By Friday, rain is gone, and sunshine will return for Friday into this next weekend.
