00:00 Well, so much needed rain.

00:01 That's what we're going to be

00:02 talking about across the central

00:04 Gulf Coast states and the Southeast.

00:05 As we go over the next 24 hours,

00:07 I say much needed.

00:08 Take a look at the drought monitor here.

00:11 You know when when the season started,

00:12 when the early summer started,

00:14 where was the drought?

00:15 It was in West Texas,

00:16 but as we continue to see that heat build,

00:19 not only across Texas,

00:20 but the central Gulf Coast states.

00:22 The drought then started to extend

00:24 eastward and does include most of

00:26 Mississippi Southern Mississippi

00:26 and also in the Louisiana area.

00:28 And now you're starting to see that

00:30 drought start to encroach to the

00:32 Northeast across southern parts of

00:34 Georgia, Alabama and the upstate

00:36 of South Carolina.

00:37 But we are looking at some much needed rain.

00:39 I want to show you the water vapor loop here.

00:43 Now we've had rain this morning from

00:45 what was a very powerful Hurricane Lydia.

00:47 It made made landfall near Porta

00:49 Vallarta yesterday afternoon.

00:51 That moisture going into Texas.

00:52 That's why it's been raining here,

00:54 but we've also watched this.

00:56 Look at this area.

00:57 Tropical moisture.

00:58 You see the dark greens and the white.

01:01 That's an area of low pressure that's

01:03 been moving northward from the Bay of

01:06 Campeche now I don't think this is going

01:08 to develop I think there's too much

01:10 wind shear here but there's a lot of

01:12 moisture with this and that is all

01:14 headed where and you can see as far

01:17 West as New Orleans as far east as

01:19 Tampa and Orlando within this zone.

01:21 We're going to be picking up a lot

01:23 of showers and thunderstorms and

01:24 actually some locally heavy rain here.

01:26 On on the satellite and radar you

01:28 could see already that rain falling.

01:30 Here's our an area of low pressure

01:32 now north of this warm front.

01:34 We have a drier air mass in place.

01:36 And what are you doing?

01:37 You taking all this tropical

01:39 moisture to ram it northward.

01:40 It's going to comply,

01:41 collide with that dry air.

01:43 That's why you're going to see a

01:45 large shield of rain with this as

01:47 we move through this afternoon and

01:48 tonight there it goes with the rain

01:50 getting all the way up toward Interstate

01:52 20 now from let's say Birmingham

01:54 toward Atlanta toward Columbia.

01:55 I don't think we're getting heavy rain,

01:57 but it's going to be a soaking rain.

02:00 I could see about 1/2 inch,

02:01 maybe up to an inch of rain,

02:03 and that's going to cause travel delays.

02:05 The heaviest rain that was going to be

02:07 farther South right along Interstate 20.

02:09 Soaking rain around New Orleans toward

02:11 Gulfport, Mississippi toward Mobile,

02:12 Alabama.

02:12 Watch that rain after 2 o'clock.

02:14 Start to spread into where Pensacola,

02:16 Panama City, Apalachicola.

02:16 Still, there's that soaking rain,

02:18 southern parts of Alabama and Georgia.

02:20 The other thing I want to point you out

02:22 with point out with the rain is that

02:24 I want to point out right now is look

02:27 at this what we call is a V notch signature.

02:29 You see that on the southern tail of this.

02:32 This is where you have severe weather.

02:34 Now this is at 6 o'clock where

02:36 watch where that area is going.

02:38 It is going into North Florida tonight.

02:40 I'm worried that we could be looking

02:42 at severe weather well after dark

02:44 tonight across North Florida and

02:46 that will include the big bend of

02:48 Florida toward Tampa as well and I

02:50 can see Orlando in this as well.

02:52 There's a heavier rain continuing

02:54 also across the eastern Carolinas.

02:56 And even tomorrow morning you see

02:58 these thunderstorms, southern Georgia,

02:59 and into the panhandle of Florida.

03:01 I'd worry about that.

03:03 These are severe,

03:04 so we have a very nasty night coming

03:06 here weather wise across North Florida

03:08 and southern parts of Georgia.

03:10 Then everything ends from West to

03:12 East as we head toward tomorrow and

03:15 will start to improve the weather.

03:17 However, keep an eye on this

03:18 area tomorrow afternoon.

03:19 Once again across the central

03:21 Florida Peninsula.

03:22 There may be additional strong

03:23 to severe thunderstorms.

03:24 How much rain?

03:25 Quite a bit now it's going to be

03:27 falling in about an 18 hour period,

03:29 so I don't think we're looking

03:31 at flash flooding,

03:32 but this rain will cause at least

03:34 localized flooding and there's going

03:35 to be a ponding of water on the roads.

03:38 I-10 is going to be impacted even I-20

03:40 and the reduced visibility will

03:42 cause slowdowns certainly from

03:43 New Orleans toward Appalachia,

03:45 Kola, Pensacola,

03:45 Tallahassee toward Jacksonville.

03:46 2 to 4 inches of rain,

03:48 but even from Tampa toward Savannah

03:50 and close to Montgomery there will

03:52 be an inch or two and then we can't

03:55 forget about the severe weather.

03:56 Some risk means spotty,

03:58 severe thunderstorms that will

03:59 have isolated tornadoes,

04:00 water spouts,

04:01 locally damaging wind gusts,

04:02 and there's certainly going

04:03 to be some downpours here.

04:05 Once you get in that moderate area,

04:07 that's where you're looking at the

04:08 orange from Cedar Key toward Miami.

04:10 Now you're talking that the severe

04:12 thunderstorms are going to be more numerous.

04:14 As I mentioned,

04:15 this is going to be a very stormy

04:18 night across the southeast,

04:19 specifically Central and Northern Florida.
