🌩️ Severe Weather Forecast and Trough-Ridge Pattern Analysis

The video script begins with a discussion of the active weather patterns, particularly focusing on the satellite imagery showing showers and thunderstorms in Florida and fast-moving clouds across the Pacific, indicating a significant weather event. The presenter highlights the convergence of air masses from the north and the south, which is a precursor to severe weather downstream. The main driver of the upcoming weather is the contrast between below-average temperatures in the West and above-average temperatures in the East, creating a trough and ridge pattern. This is expected to result in extreme heat in Texas and Florida over the next 10 days. The potential for severe weather is underscored by the expected rainfall map, which shows hot spots for storms in the northern and mid Mississippi River Valley areas. The script details the risk of severe weather, particularly in Dodge City and Wichita, with a moderate risk of 80 mph wind gusts and the possibility of a derecho. The tornado threat is present but not the primary concern. The radar forecast shows potential for storms to intensify into a mesoscale convective system (MCS) with damaging winds, especially in Kansas. The script concludes with a look at the HRRR model, which suggests a potential for supercells and further severe weather development.

🌪️ Anticipated Severe Weather Outbreak and Impact Analysis

The second paragraph delves into the forecast for a severe weather outbreak, potentially of epic proportions, driven by a significant dip in the jet stream and the convergence of cold air from Canada with warm, moist air from the Gulf of Mexico and the Pacific Stream. The script discusses the likelihood of this setup leading to severe weather, especially given the time of year and the lack of blocking weather patterns. The presenter anticipates an enhanced risk of severe weather on Tuesday, with a focus on areas that have already been impacted by severe weather this year. The potential for high convective available potential energy (CAPE) is highlighted, which could lead to a rapid development of storms. The recurring pattern of unstable air masses in the Midwest and South Central US is expected to continue, with the Storm Prediction Center already indicating a large area under a slight risk of severe weather for Wednesday, May 22nd. The script concludes with a mention of the ongoing efforts to support those affected by severe weather, including a recent tornado outbreak, and an invitation to subscribe to the channel for updates.

Keywords

💡Severe Weather

Severe weather refers to any potentially hazardous meteorological phenomenon that can cause damage, injury, or loss of life. In the video, the speaker discusses the potential for severe weather, including thunderstorms and tornadoes, across various regions of the United States. It is a central theme of the video as the speaker aims to inform viewers about the risks and developments of such weather events.

💡Trough

A trough, in meteorology, is a long, narrow region of low atmospheric pressure. The video mentions a trough and ridge pattern as a key driving mechanism for the expected weather. Troughs can lead to unsettled weather and are associated with the development of storms and precipitation, which is relevant to the discussion of severe weather threats.

💡Ridge

A ridge is the opposite of a trough; it is a region of high atmospheric pressure. The script refers to a ridge pattern in the context of above-average temperatures, particularly in Texas and Florida. Ridges often bring settled weather, but in this case, it's associated with the potential for very hot conditions that could contribute to severe weather.

💡Convective Available Potential Energy (CAPE)

CAPE is a measure of the amount of energy available for the development of thunderstorms. It is a key concept in the video as it quantifies the potential for severe weather. The speaker mentions that there will be a significant amount of CAPE, indicating a high likelihood of thunderstorm development and severe weather events.

💡Mesoscale Convective System (MCS)

An MCS is a complex of thunderstorms that covers a large area, typically over 400 km across. In the video, the speaker anticipates the formation of an MCS in Kansas, which is expected to produce damaging winds. MCSs are significant weather phenomena that can lead to severe weather conditions such as heavy rain, hail, and strong winds.

💡Derecho

A derecho is a widespread, long-lived windstorm associated with a band of rapidly moving thunderstorms. The term is used in the video to describe a potential severe weather event. Derechos can cause extensive damage due to high winds and are an example of the type of severe weather the speaker is monitoring.

💡Tornado

A tornado is a rapidly rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. The video discusses the potential for tornadoes, particularly in the context of the interaction between different air masses. Tornadoes are a significant concern in severe weather forecasts due to their potential for causing destruction.

💡Hail

Hail is a form of solid precipitation consisting of balls or irregular lumps of ice. In the video, hail is mentioned as a potential weather hazard, particularly in the early stages of storm development. Hail can cause damage to property and crops and is a common feature of severe thunderstorms.

💡Wind Gusts

Wind gusts are brief bursts of wind that are significantly stronger than the average wind speed. The video discusses the potential for 80-mile-per-hour wind gusts, which are associated with the severe weather risk. Wind gusts can cause damage, especially when they are strong and unexpected.

💡Storm Prediction Center

The Storm Prediction Center is a branch of the National Weather Service that issues forecasts and warnings for severe thunderstorms and tornadoes across the United States. The video references the Storm Prediction Center's role in highlighting areas under risk for severe weather, indicating the importance of their forecasts in preparing for and responding to severe weather events.

💡Jet Stream

The jet stream is a relatively narrow, meandering air current in the upper part of the Earth's troposphere which moves weather systems across the atmosphere. The video mentions a dip in the jet stream as a factor contributing to the severe weather. Jet streams can influence the development and movement of weather systems, including the potential for severe weather.

Highlights

A very busy week of weather events is anticipated with showers and thunderstorms moving through Florida.

Clouds racing across the Pacific are expected to affect Mexico and the southwestern United States.

The interaction of air masses from the north and the Pacific suggests an active weather period for downstream areas.

Below average temperatures in the West and above average in the East are the main drivers for the upcoming weather.

Severe weather potential is heightened where these air masses meet, particularly in Texas and Florida over the next 10 days.

Total expected rainfall through Sunday, May 26th, shows two significant hot spots for storms.

A moderate risk of severe weather is forecast for Dodge City and Wichita, with a slight risk extending to North Dakota.

The primary threat of severe weather today is from 80 mph wind gusts, with a possibility of a derecho.

A 5% probability of tornadoes exists in Topeka, Wichita, and Dodge City, though not the main concern.

Storms are expected to intensify in the evening with damaging winds becoming a larger problem.

A mesoscale convective system (MCS) is expected to form in Kansas by the evening, posing a threat of damaging winds.

The HRRR model suggests a potential for supercells or a multi-cellular cluster in Oklahoma, indicating a tornado threat.

Severe weather threat is predicted to decrease in the early morning hours but will ramp up again on Monday.

A more discrete cellular system on Monday might increase the tornado threat, although conditions for tornado genesis are limited.

A significant severe weather outbreak is anticipated on Tuesday with a large dip in the jet stream.

Convective Available Potential Energy (CAPE) is expected to be very high, particularly in Nebraska and Iowa.

The pattern of trough dips suggests a continuation of severe weather through the end of May.

The Storm Prediction Center has highlighted a large area under a slight risk of severe weather for Wednesday, May 22nd.

A potential break in severe weather may occur around the beginning of June.

00:00

Things are getting plum wild out there in the  weather world. It's about to be a very busy week,  

00:05

and I'm here to try to make it all make sense to  you. This is what the satellite looks like as I'm  

00:10

recording this video. We've got some showers and  thunderstorms moving through Florida. This is our  

00:14

next big troublemaker, okay? This is what we're  going to be talking about a lot today, but I want  

00:18

you to pay attention to these clouds down here,  okay? See how they're racing across the Pacific,  

00:23

getting ready to go over the Baja Peninsula. All  of that moisture is working up towards Mexico and  

00:27

the southwestern United States. eventually  that's gonna pour over into the plains. But  

00:31

I want you to notice something else. Look at  these clouds from the north also coming down  

00:35

in the same area. Whenever we see that kind of  mixing, whenever we see those two air masses  

00:40

pointing towards each other, it usually means  a very active or at least a very interesting  

00:45

period of weather for the areas downstream, okay? So that's what's going on. The main driving  

00:51

mechanism for all the crazy weather we're about  to experience is the below average temperatures  

00:56

in the West and the very much above average  temperatures in the east. We've got this trough  

01:01

and ridge pattern. We're going to be, I mean, just  absolutely blazing hot in Texas and Florida over  

01:06

the next 10 days or so. And remember, where those  two air masses meet, that's where we are mostly  

01:12

concerned about the very real potential for severe  weather. We're going to have a lot of different  

01:16

opportunities right here in this channel. A pretty  good way to quantify this is by looking at the  

01:21

total expected rainfall over the next week or so.  This is through Sunday May 26th. You can see that  

01:27

we've got two big hot spots one up here towards  the north and then another one down here towards  

01:31

the mid Mississippi River Valley back towards the  Red River Valley. This is where we're gonna see a  

01:35

lot of storms over the next little bit and we're  also gonna see storms in the middle don't get me  

01:39

wrong in fact some of our strongest storms might  occur in the middle here we'll talk about that  

01:43

here in a minute but you can see where all the  stormy weather is gonna be most concentrated  

01:48

over the next week. Starting today we've got a  moderate risk a four out of five severe weather  

01:52

risk for Dodge City and Wichita. Slight risk goes  all the way up to close to Aberdeen and a little  

01:58

bit of southern portions of North Dakota. This  is mostly driven by a wind threat okay so most  

02:03

of our moderate risks this year have been tornado  driven. This one is 80 mile per hour wind gusts  

02:09

maybe even higher. We might even see a derecho  today. It's obviously we don't know that we won't  

02:14

know until after the storms over but that's kind  of what we're watching for in Dodge City, Topeka,  

02:19

and Wichita today as a really strong line of  storms is going to come through the hatched  

02:24

region here and we do expect to see some intense  damaging winds. The tornado threat is not the main  

02:29

driving factor behind today's severe weather  risk but it's also not zero. We do have a 5%  

02:34

probability of seeing a tornado or two in Topeka,  Wichita, and Dodge City as well. You know, I just  

02:39

don't think that the tornado threat is going to  be the main thing today. With that being said,  

02:43

let's take a look at the radar and what it could  look like as the day progresses. Here we are about  

02:48

4 or 5 p.m. We're gonna start to see storms fire  up in the front range of Colorado over towards  

02:53

the panhandle of Oklahoma, western Kansas, up here  into Nebraska and South Dakota as well. When these  

02:59

things first pop up, hail and winds are gonna be  a problem, but the big-time damaging winds won't  

03:05

become a larger problem until we get a little  bit more organization. You can see that we have  

03:09

a full-fledged MCS or mesoscale convective system  expected here in Kansas by around 7 or 8 p.m. this  

03:17

evening. We're also going to have some scattered  severe thunderstorms down here in the southeast as  

03:21

well. Look out down there near Savannah, Georgia  down towards pretty much the entire peninsula of  

03:26

Florida. But once again around 8 p.m. we're  gonna be watching this MCS potentially cause  

03:30

damaging winds here as it moves through Kansas.  Now the HRRR model is continuing to try to paint a  

03:36

supercell or maybe another multi cellular cluster  down here to the south of that main line. If this  

03:42

is the case, then we might have a little bit  more of a tornado threat down here in Oklahoma.  

03:47

But right now, most of the models and most of the  guidance is just expecting to see this big bowing  

03:51

segment of strong storms up here in Kansas.  Between 9 and 10 p.m. this evening, that's  

03:56

when some of the strongest winds are going to be  expected. We are expecting some strong storms up  

04:00

here farther to the north as well, as far north  as Canada. A lot of Minnesota down here into South  

04:05

Dakota and Nebraska, you guys are going to get in  on some of these strong storms, but they're not  

04:09

going to be nearly as intense what we're seeing  down here farther to the south. Now I think that  

04:14

once we lose that daytime heating and especially  as we go towards 1 a.m. 2 a.m. in the early  

04:18

morning hours tomorrow the severe weather threat  is going to die down a little bit but as you can  

04:23

see here as predicted by the Storm Prediction  Center it's gonna ramp right back up as we go  

04:27

into the heating of the day on Monday where we  have another slight risk of severe weather here.  

04:31

Notice how those original storms kind of fizzle  out and their outflow boundaries give way to new  

04:36

storms as we go into the afternoon and evening  hours. On Monday, a little bit more of a discrete  

04:42

kind of pop-up cellular kind of system on Monday.  That might mean that there's a little bit more of  

04:48

a tornado threat here. However, the ingredients  for tornado genesis aren't going to be very ample,  

04:54

I guess I should say. So I'm not seeing a huge  tornado outbreak with this. However, the fact that  

04:59

we are seeing some more isolated convection, maybe  it's a sign that we should watch it a little bit  

05:03

more closely. But this is also going to organize  into a big-time MCS or cluster of storms that'll  

05:10

probably mostly be a damaging wind producer as we  get into the early morning hours on Tuesday. And  

05:16

by Georgie's, it doesn't even stop there. I want  you to look at this. This little divot right here  

05:20

on our 500 millibar map, that's what's causing  all of our problems with our potential derecho  

05:24

and all that stuff today and tomorrow. That little  dip, alright, as inconspicuous as a little blip,  

05:30

never underestimate a dip. We've got ourselves  a much bigger dip coming in on Tuesday, okay,  

05:35

so this more substantial trough here is going to  bring in some of that cold air from Canada and  

05:39

allow for a lot of lift from you know the Gulf  of Mexico and it's also going to combine that  

05:44

Pacific Stream in this mixture and this is when  we're really going to start to see our big-time  

05:48

severe weather threats start to actualize.  Tuesday we're gonna see all these ingredients  

05:53

come together we're gonna have a much larger  dip in the jet stream here. I do expect a severe  

05:58

weather outbreak of potentially epic proportions  on Tuesday. Now I don't know if this is going to  

06:03

be a tornado outbreak or a, you know, another  derecho kind of thing. It's too early to talk  

06:08

about that right now, but I am very confident  that given climatology, okay, it's May 21st,  

06:14

whenever we see a, you know, a big trough like  this on May 21st and there's not anything blocking  

06:19

the southern flow from the Gulf of Mexico, this  is going to be a pretty big time severe weather  

06:23

event. So we're watching it closely. So is the  storm prediction. Already got that day enhanced  

06:28

risk here for La Crosse, down through Des Moines,  Kansas City, Topeka once again. Unfortunately it's  

06:34

gonna be impacting a lot of people that have  been impacted already by severe weather this  

06:38

year and probably are done with it. If there's a  day that we're gonna go live on this channel this  

06:43

is gonna be it I think. On Tuesday we are gonna  have quite a bit of CAPE convective available  

06:48

potential energy. Maybe you know as far north as  into Nebraska and Iowa maybe over 3,000 joules  

06:53

per kilogram which is and we're gonna see that  kind of getting eaten up really quickly as that  

06:57

line of storms does eventually form. But you  can see here that we're just going to have a  

07:01

recurring pattern where very unstable air masses  are going to be able to form here in the Midwest  

07:07

down into the South Central US. And if we continue  to watch our trough patterns, look there's another  

07:12

dip that comes through on Wednesday May 22nd.  Another dip, another dip, like this is a pattern,  

07:18

this southwest to northeast pattern where we have  a Separation between cool air and warm air in May  

07:25

is just kind of the perfect setup for severe  weather So like as long as that continues to  

07:29

be the case We're gonna have a lot of chances  of severe weather and it looks like that's  

07:33

gonna continue to be the case all the way through  Maybe the end of May so we might get a little bit  

07:37

of a break right around the beginning of June it  seems But right now we are locked in Sun all the  

07:42

way through May 28th At least storm prediction  center already highlighting a huge area under a  

07:48

slight risk of severe weather on Wednesday, May  22nd This is from Detroit and Cleveland, Ohio,  

07:53

back towards Dallas and Waco. And then a rare  day five, slight risk in Oklahoma, Arkansas, 

07:59

Texas, and Louisiana. So you guys, once again,  

08:02

are going to get tired of seeing my face. I think  over the next week or so. All right. That's all  

08:06

the weather talk I have for you today. Once  again, I don't think that I'm going to be going  

08:10

live for today's wind threat. However, there  is a chance that I go live tomorrow. There's  

08:14

a chance that I go live on Tuesday, especially  there's a chance I go live Wednesday and Thursday  

08:20

as well. So make sure you're subscribed to  the channel with notifications on and also,  

08:23

please subscribe to the y'all squad our channel  over here We're about to hit 35,000 subscribers.  

08:29

Just search the y'all squad on YouTube We've got a  new video that we just did on the tornado outbreak  

08:34

that occurred in Nebraska, Iowa and Oklahoma On  April 26th and April 27th We've spent well over  

08:40

a hundred thousand dollars at this point helping  people that have been impacted by severe weather  

08:44

and we're still on the ground Doing work right  now We've got another update video coming for  

08:48

you at the end of May if anybody has you know  Contributed at all you can see how that money is  

08:54

doing work here through these videos once again a  tornado Destroyed her house while she was inside.  

08:59

That's the latest one there about our  significant tornado outbreak that occurred  

09:03

last month Thank you all so much for watching.  I'll see you in the next one. Goodbye Whoop!
