In today's Forecast Feed, AccuWeather's Bernie Rayno breaks down the severe weather that is expected to persist throughout the week in the central U.S. with hail, heavy rain and isolated tornadoes.
Transcript
00:00All right, we've had a break from severe weather this week, but on the feed, we're going to talk
00:03about the return to severe weather, but I don't see any widespread severe weather outbreaks here
00:10over the next three to four days. We may have to worry about the middle part of the week.
00:14Now, there's going to be some severe weather, but I just don't think it's going to be widespread.
00:18Let me show you what it's going to look like here over the next few days. We begin on Thursday.
00:23There it is across the Plains states, mostly wind and hail with this one, wind and hail,
00:27wind and hail, Thursday, Friday, Saturday, any tornadoes are going to be isolated.
00:32And the severe weather threats continue even beyond this time period. Take a look. Here's
00:37what we have for you on Sunday, or I should say, yeah, on Sunday, again, an elongated area. But as
00:43you're going to see, there's not a lot of energy with this right now. There's enough warmth and
00:49enough humidity, but not a lot of energy for widespread severe weather. And even as we head
00:54into Monday, same story, it's an elongated area from the Midwest toward Texas. Can there be isolated
01:00severe weather, including tornadoes? Yes, but nothing widespread. Now, we're going to keep an eye
01:06on Tuesday. As we get in the middle part of next week, and I'll show you why. Now, here's where
01:11the
01:11energy is coming. It's off the West Coast. This is what's going to produce the severe weather here
01:16over the weekend, this upper low. But as you're going to see, it's going to weaken. Now, middle part of
01:21next week, we have energy in the Gulf of Alaska. That's going to come southeast. Our first system
01:27in the plains, this has more energy with it than our storm off the West Coast. It just doesn't have
01:34a lot of unstable air associated with it. Let me show you what I mean. Let's go to the modeling
01:40here,
01:40and I'm going to show you the tools that I use as we try to predict this severe weather here
01:46over
01:46the next couple of days. So, let's talk about this system coming in down across the Canadian
01:51prairies. Here it comes as we head into Thursday and Friday. A lot of energy with this. See how that
01:56swings through? And there's a frontal boundary. And even this, this is always a little concerning to
02:01me. Thursday night, Friday morning, you see this little low pressure system here? We call it a
02:06triple point low because you have a cold front, you have a warm front here, cold front here, storm here,
02:12cold front. We call this a triple point low. And oftentimes, you can get tornadoes with these
02:18if you have a right amount of air. You see how you have that low pressure system going across
02:21Illinois? But as I take a look, a closer look at this, while we look at the low-level jet
02:27for
02:27energy, and look, you have a pretty strong low-level jet here showing you you have energy in the
02:31atmosphere. You see this? As we get in the late Thursday night, Friday morning, what you are lacking
02:38is moisture. And dew point temperature is only in the, you see this dew point temperature? Middle
02:4350s. Now, if you had 65 or 70 degree dew points coming in here, I'd be a little more worried.
02:49But I think you have the energy, but you don't have the moisture. So that's why I'm not too worried
02:53about this area as we get into Friday. But as mentioned, we're also tracking that system off
03:00the West Coast. And little pieces start coming out. Here's one on Thursday and Friday. You see
03:06that? Not a lot of energy. Not a lot of energy. But we do have thunderstorms posted on Thursday and
03:13Friday. And let me show you why I'm not too worried. While you certainly have Thursday and Friday,
03:18you've got plenty of moisture coming in and out of the Gulf. Look at it certainly by Friday.
03:22You've got all this energy coming out of the Gulf of Mexico, a lot of this moisture. There's just
03:28not a lot of energy associated with this. You go back to the 500 millibar here. What do you have
03:34Thursday and Friday? Not much. Little pieces, but not a lot. Another way to look at it is the low
03:41-level
03:41jet Thursday and Friday. You see, you've got the low-level jet up here showing you a lot of wind
03:47energy, but not much in Texas. And even on Saturday, where's a lot of the energy? Up here. Up here
03:54across the Plains states. That's why we have some risk up there. But when you look at, well, okay,
04:01do you have the energy? Do you have the moisture up there on Friday? Look at our dew point temperatures
04:06up on Friday. Not really. See, you've got the energy Friday and Saturday. There it is, Saturday night.
04:13All the energy across the Plains, but all the moisture is down in Texas. So where you have the energy,
04:20you don't have the moisture. And where you have the moisture, you don't have the energy. Nothing is
04:25coming together as we get in the Saturday and even Sunday. And if I go back to this, you'll notice
04:32that
04:32our severe weather threat on Sunday, that's why we only have a some risk. You see that? Because
04:40not all of the ingredients are coming together. Now, take a look. There's Monday. All right. There's
04:47what we have on Monday. Again, it's a some risk. Why don't we have a moderate? Well, let's take a
04:52look at it. What are we going on on Monday with energy? You do have some. You do have some.
04:57But
04:57what's happening is this upper low off the California coast is going to weaken. Watch me
05:03play it forward. Friday, you see how it weakens? Because that other piece of energy in the Gulf of
05:07Alaska follows it. So what happens is it comes out in pieces. So instead of getting one big day of
05:14severe weather, you just get pieces of severe weather. That's it. Look at Monday. There's that
05:18piece of energy. You can see models showing showers and thunderstorms in here. But when you take a look
05:24at the energy and dew points. So Monday, you've got plenty of moisture. Look at our dew point
05:30temperatures in the 60s in here. You see? But when you look at the wind energy, there's just not a
05:36lot.
05:37There's just not a lot. Now, one thing I think you do have to worry about is this next piece
05:45coming
05:45in across the Gulf of Alaska. There it is. See this in here? This is the one to keep an
05:50eye on.
05:51Because as we go forward, watch it come across the country. And you start talking Tuesday and
05:56Wednesday. This is where I start getting worried as we get into Wednesday. Tuesday, let me go back to
06:06this. Tuesday, we still only have some risk. Once again, no moderate. Why? Well, when you look at the
06:13ingredients here, you have some energy coming out here across the Midwest. But again, as you look at
06:22the low-level jet, it's weakening during the day. On Tuesday, you have the moisture, but the energy is
06:26weakening. But here's the time to watch Wednesday into Thursday. You see this? All of a sudden, you have
06:34that energy coming out. Look at the increasing low-level jet across Indiana, Tennessee, and you
06:40have higher dew point air. That's the time frame to watch for more severe weather than what we're
06:46going to see over the next couple of days. Middle part of next week, and that's the feed.
