Showers and thunderstorms will frequent parts of the Southeast through the weekend, and AccuWeather forecasters say there is a chance they could organize into a tropical system.

00:00 Well, the wet pattern continues across Florida, but it's not going to be as wet across Florida

00:07 as what we've seen so far this week.

00:09 Now the overall pattern hasn't changed.

00:11 We have this frontal boundary again that has been stalled across north Florida.

00:15 Here's what happens.

00:16 Out ahead of that front or north of the front, the wind comes in out of the north.

00:20 South of the front comes in out of the south-southeast.

00:22 And you know what you get?

00:23 You get this convergence along the boundary where the air comes together.

00:27 And when you get convergence, the air comes up.

00:30 It's forced.

00:31 It collides.

00:32 It's forced to go up.

00:33 You get showers and thunderstorms.

00:34 And of course, south of this boundary, what you're also dealing with is a lot of unsettled

00:38 air, warm, humid air.

00:40 With the sun out, we get some thunderstorms.

00:42 Now, the last couple of days, those thunderstorms have been numerous.

00:45 Not as much the next couple of days.

00:47 And here's why.

00:49 Last couple of days, we've had this surge of tropical moisture coming in from the Caribbean

00:55 into Florida.

00:56 Yesterday, it was more widespread.

00:57 It covered the entire state.

00:59 Today, notice where it is.

01:01 South Florida.

01:02 That's where it's been cloudy much of the time.

01:03 And this is where I think you're going to get the bulk of the thunderstorms as we go

01:07 through today.

01:08 Now, having said that, along that boundary, we're still going to have thunderstorms popping

01:12 as we go through the afternoon.

01:14 Here they are.

01:15 They're very spotty, though.

01:16 Watch what happens later on this afternoon.

01:19 Let me clear the screen here.

01:21 And let me highlight this for you.

01:23 We'll spotlight it.

01:24 Watch this area across south Florida.

01:27 Thunderstorms start to become a little more numerous, don't they?

01:29 And they're also very slow moving.

01:31 So there's going to be some big-time rain with these thunderstorms.

01:34 Now, same story in north Florida.

01:36 The thunderstorms are spottier, but they're going to be able to produce some locally heavy

01:40 rain as they sit in areas for an extended period of time.

01:43 The other story is, last couple of nights, the thunderstorm lingered well after midnight.

01:48 We're not going to see this.

01:50 Once the sun goes down, I think the thunderstorms are going to collapse.

01:53 As we head toward Friday and the upcoming weekend, you're going to start seeing that

01:56 frontal boundary push south a little bit here.

01:59 So less thunderstorms in north Florida.

02:01 But I'll tell you what, right through the weekend, it's south Florida that we're going

02:04 to see where we're going to see the lion's share of the thunderstorms.

02:08 And that's probably, certainly is the highest risk for flash flooding.
