Flash flood threat stretches across the South

Rounds of heavy rain on Tuesday caused flood warnings from the Texas coast to the Tennessee Valley, and the threat isn't over yet.

Transcript

00:00 Our top story tonight is going to take us to the south where we're warming up but we now have a

00:04 flash flood threat. We saw flash flooding yesterday near Austin, Texas. Now the flood threat has

00:09 shifted east and I'll tell you what here folks, we've got a very slow moving upper level low

00:14 pressure system which is just going to wreak havoc across east Texas and eastward as we head through

00:20 the next couple of days. So we're not even close to being done with this flooding event. Here's a

00:24 look at the radar picture. You see a fetch of moisture stretching from yeah southeast Texas

00:29 between Houston and Dallas and San Antonio all the way up into areas around St. Louis. So some

00:34 major areas are being impacted here with heavy rain and thunderstorms. We've also had a lot of

00:39 flash flood reports here across portions of east Texas and up into Arkansas as well. You see them

00:45 flashing those flashing green polygons and of course we've got some thunderstorms in here too.

00:49 A few of these storms could produce some not just flooding downpours between Houston, Dallas,

00:55 Austin and San Antonio in the coming hours but also some gusty winds. You know we have another

00:59 weather hazard out there folks. I want to show you a dense fog advisory is in effect for the

01:04 second straight night for much of the center of the nation. Now this includes places like Dallas

01:08 and DFW airport just said they've got a ground stop. They've got too much fog in Dallas to bring

01:13 the planes in or out so that's a big problem for us. Weather delays all over the place here from

01:18 Chicago southward. I mean fog is one of the worst conditions you can have when you're trying to fly.

01:24 You have to be able to see. Now we also have a lot of flood watches and warnings as you might

01:28 imagine. It's been a very rainy day here from the Texas coast into east Texas and all the way up

01:34 into the Tennessee valley. Flood watches continue because we're going to have another couple of

01:38 rainy days to come. I mean we are sitting here on Tuesday night and through Thursday at least

01:44 there'll be a zone here from the Texas coast all the way up to the lower Mississippi valley and

01:49 even the Tennessee valley where we will have frequent downpours, flash flooding and big-time

01:54 travel disruptions. The rainfall forecast is still formidable. If you're in the yellow here over the

01:59 next several days that's at least two inches, orange is at least four inches. There will be

02:03 pockets of well over that as we move forward in time. The rainfall forecast here includes some

02:08 rain that has already fallen which started on Sunday night and it lasts through Thursday night.

02:12 This darkest green shade here has expanded a bit. That's the 8 to 12 inch zone here folks.

02:18 That is way too much rain. Even though you're into drought it'll be beneficial in that sense but we

02:23 know we're going to have big-time flooding concerns. Now here's a wide view of the radar.

02:27 Again you see the flash flood warnings firing off here between right around the Arklatex.

02:32 I'm going to be watching for some heavy rain into Memphis tonight. Some of these storms from

02:37 tonight, tomorrow and tomorrow night could be severe. We've got some risk of flooding, hail

02:42 and even a few tornadoes. So to go along with that flood threat and water over the roads we're also

02:47 going to be having to watch out for the the severe thunderstorm aspect of this situation.

02:51 Wednesday's forecast, yeah some of the same areas getting hit hard with the heavy rain and the

02:56 thunderstorms. Fast forward to Thursday the rain moves a bit farther to the east so Texas will dry

03:02 out by Thursday the way it looks now and Friday there will be some lingering rain around the

03:07 southeast U.S. New Orleans it's not going to be very easy to navigate there for the next few days.

03:13 A lot of rain.
