A HUGE Storm Threat Is Coming...

Hinzugefügt: 2026-05-05

[00:00:00]Hey, good morning, good afternoon everybody. Welcome back to Weather on the Go, all your weather coverage. My name is Hunter and it is Tuesday, April 21st, 2026. Hopefully everybody's having a wonderful Tuesday. Wonderful week out there so far. We have a marathon of severe weather in the forecast and it really begins on Wednesday going through the next say week of weather going through the middle of next week. So, this could include damaging winds, large hail, and tornadoes. We got to be on high alert if you live across parts of the central United States into the southeast. And we got to look at some snowfall prospects in the mountains out west. We got a lot of snow coming there and our temperature trends heading through early May. Got a lot to cover in this forecast. So, make sure to like the video, give it a thumbs up, share the video, and subscribe to the YouTube channel. And it is free to do. It doesn't cost anything. We cover the United States, southern Canada, and the tropics. So, without further ado, let's get into the forecast details. And what we're looking at here is the upper levels of the atmosphere really kind of telling the story of what's going to happen over the next several days. We got a big ridge of high pressure that is highlighted here in yellow and orange.

[00:01:10]And what a ridge of high pressure does typically is bring sunnier conditions and drier weather. In the blue, that is a trough. And troughs typically bring cooler weather and lots of precipitation. And you can see that trough we have across the West Coast.

[00:01:26]That's a big storm that's moving into California and the West. And that is going to continue over the next 24 hours into tomorrow. Eventually, we're going to see a strong surface cyclone really start to develop here across Saskatchewan in Canada. Notice it's very slow moving, if not almost stalling out up here and oluding. So that means we're going to be seeing day after day after day of shower and storm activity across portions of the Northwest and into the northern part of the United States. As we get into the weekend, we got another trough developing over here just west of California offshore. This second trough is going to dig a little bit further to the south as we go in through the weekend. That one will be ejecting across the country here and bringing us a more widespread brand of some unsettled weather as we get into early next week. So, let's look at the jetream orientation. You can see it's almost a cut off low pressure. You got the polar jet up here to the north through Canada.

[00:02:26]You got a little bit of a branch of the subtropical jet underneath it, but in between it's kind of a cut off low. It's not really attached to anything. And that's why it's kind of slow moving until it really gets up here into Canada. And even then it becomes cut off because the polar jet is weakening. So that's going to in itself slow down the system. It's going to stall out a little bit and then the subtropical jet becomes the main feature as we get into the weekend and then especially early next week as that starts to move in across the south central tier of the United States. Here's what we got going for today. And we do have some precipitation with that cutoff low across the west. So California up into Oregon in green simple terms is rainfall and blue simplistic terms that is snowfall. And you can see there is some snow and some blue there across the Sierra Mountains in California. And that is going to be piling up fairly well over the next 24 hours straight through the day there on Wednesday. Eventually that snow is going to be moving up into the Cascades in the Northwest Rockies. So, we're talking more snow, higher elevations of Oregon, Idaho, northern Nevada, getting into western Wyoming, even northern Utah there, stretching up into Montana. And that's what we're going to be seeing going into the day on Wednesday. Look at all the precipitation we see out west, including parts of the Sacramento Valley here up there into the Pacific Northwest. Some measurable precipitation going through Wednesday morning. And the snowfall is going to be the big story in the higher elevations of the Sierra Mountains especially. We could be seeing up to four feet of snow and this is going to be coming down really within the next 24 to 36 hours at that. So going back to our trough, we can see here in blue across the Pacific Northwest on Wednesday. So this is for tomorrow, April 22nd. This is going to develop across Saskatchewan a low pressure system and it's going to stall out. It's going to slow down here as we go through Thursday and Friday and even into Saturday morning. And what that's going to do is kind of set up a little bit of a severe weather episode across the central United States because a dry line and a cold front will be moving through. Here's the dry line setup for tomorrow for Wednesday, April 22nd.

[00:04:35]Marginal risk in dark green for severe weather, isolated storms from South Dakota all the way down here into the portions of West Texas, the Texas panhandle, also through Nebraska, western Kansas there in the Oklahoma panhandle. You guys are also included.

[00:04:49]Going into Thursday, this shifts a little bit further to the east. A little bit more heightened day of severe weather on Thursday. You got a yellow zone here for scattered severe storms.

[00:04:57]That's a slight risk. It's a two out of five on the risk scale extending from southern Minnesota through western Iowa, eastern Nebraska down to the Kansas City area there in Missouri and northwest Missouri and then into much of Kansas and northern Oklahoma. That's kind of the zone for severe weather. But even all the way up into the arrowhead of Minnesota and northern Minnesota, western Wisconsin, we could still see some isolated severe storms on Thursday, April 23rd. And then Friday, it slips a little bit further to the south. Again, scattered severe storms. Dallas, Fort Worth to Little Rock, Branson, Missouri.

[00:05:29]You guys are also included going into Friday, April 24th. Moisture return is going to be a little bit limited as we go into the day on Wednesday ahead of the dry line as we're just starting to see the Gulf open up. So, due points will be limited to the 50s. So that will also limit our instability there on Wednesday. Thursday, richer moisture starts to move up here into the Midwest.

[00:05:49]So we got to watch out those 60°ree due points uh getting into Iowa, parts of Missouri there, eastern Kansas and Nebraska, and then even richer due points down here into Oklahoma, Texas on Thursday. And then as we go into Friday, we're going to see that cold front shifting further to the east, bringing us more severe weather down here to the mids south and the Arclletex region.

[00:06:08]That's what we're going to be keeping an eye on with those low 60 due points going into Friday. Here's the instability. So, Wednesday, we're going to see instability all the way up along that dry line going through the Dakotas.

[00:06:19]And there's going to be enough instability, enough lift in the atmosphere to get some isolated severe storms on Wednesday. Going into Thursday, we can see a lot more instability, especially from Iowa down here into North Texas. You can see the greens, the yellows, and oranges. That's 1,000 to 2,000 jewels per kilogram of instability at the surface. And then as we go into the day on Friday, the cold front's going to shift that further to the east. The stronger instability again down here in the mids south and into the Arletex region. That's where the severe storms at least on a scattered basis will be ongoing into Friday. So here's what it looks like Wednesday morning.

[00:06:53]All is quiet tomorrow morning. And then as we go into the afternoon, really after lunchtime through around sunset, we're going to be watching out for isolated supercells. This is not a slam dunk for the dry line along the po portions of the plains here, but if a storm cell does pop up, the ingredients are there, especially for large hail and damaging wind gust and isolated brief tornado cannot be ruled out there. And the storm threat will really start to dwindle as we go into after sunset as the instability waines ahead of the dry line. Thursday morning, pretty quiet again. And then we reload the atmosphere, a more widespread brand of thunderstorms on Thursday, some of which could be severe. And this could extend all the way up to the arrowhead of Minnesota for some isolated severe weather. I think the stronger severe storms is from again southern Minnesota through Iowa, Missouri, Kansas down into northern Oklahoma. That's where damaging winds, large hail is going to be the main threat. You notice a lot of these storms are a linear. So it's a line and that's going to produce that large hail damaging wind threat. But a couple spin- up tornadoes cannot be ruled out, especially if we get any supercells out ahead of the main line here. And then Friday morning, we're going to see an ongoing threat of severe weather through the morning hours and into the afternoon. So it could be all day Friday. Could have a Boeing segment here, almost a bow echo. And that would produce a damaging wind threat down here across Arkansas, perhaps into northeast Texas, Louisiana, Mississippi. We got to watch as we go into Friday afternoon and Friday evening. That's with the first trough. So, as we go into the weekend, our second more southern trough going to be coming in here in blue across California and then skirting by across the south central United States through middle of next week. And this is going to bring a marathon of severe weather in very similar areas. That's why we call it a marathon of severe weather for Saturday, April 25th. We got severe weather from Oklahoma City and Tulsa down here to Little Rock, Dallas, Fort Worth, Waco, over towards Shreveport.

[00:08:41]Very similar areas literally as we go into Sunday, April 26th. And then as we go into Monday, shifting a little bit further to the east now we're talking over towards Nashville, Paduca, getting into Jackson, Mississippi there, Birmingham, Tuscaloosa and Huntsville all the way over toward Memphis and back to Shrivefeport as we go into Monday, April 27th. Here's the setup for then.

[00:09:02]As we go into Saturday, we're going to see that cold front dropping south and it'll start to turn back north as a warm front out ahead of the dry line. You can clearly see the dry line where the green and brown come together. That is the boundary between, you know, dry, stable air and moist, warm and unstable air out ahead of that. And you can see as we go through the weekend, very similar areas till we get a front to come through on Monday. And that kind of shifts it further to the east. A lot of instability out ahead of this uh dry line, we're going to be seeing a lot of capping issues, I think, across Oklahoma, Texas. But further east of I35, your threat for severe weather will get substantially higher, especially Sunday there and into Monday as the cap maybe isn't as strong over there. And that could promote a more widespread severe weather outbreak. So as we go into Sunday, we're going to be watching out for some big storms Monday as well.

[00:09:50]And again, Saturday can't uh you know, can't you can't discount the day on Saturday either, but I think the biggest days next week will be Sunday and then into Monday. So, the 26th, 27th of April, we really got to watch out for a more high-end day for severe weather, rainfall, and no short supply. This is a pattern change we've been waiting for across the deep south. A lot of us have been wanting some drought relief. Again, this is no drought busting rains expected, but just relief from the drought. And we could start to see that as we go into late this week, especially this weekend and then getting into next week. And a lot of us down here into Tennessee, Mississippi, Alabama, Georgia could see multiple inches of rainfall.

[00:10:28]This could cause flooding as we have more rounds coming in towards the middle of next week over the same areas. And then further west, a lot of mountain snow out here and it could be especially heavy there into the Sierras, but also up into Canada as well. Temperatures this afternoon, we're in the process of warming up across the Midwest. I know it's a chilly start to the week. Things are warming up there. As we go through the week, we're going to see more of those 80s across the Midwest. Ohio Valley, another cold front coming through as we get into the weekend.

[00:10:55]coming back north as a warm front across the deep south before yet another cold front here towards the end of April. So, a lot of ups and downs, especially the further north you go. Watching out for frost and freeze risks, especially along the US Canadian border. Brief preview of May. Looks to be near normal to below normal there in the Great Lakes Northeast for temperatures. A little bit warmer, maybe still some drought feedback across the southeast, but the warmest conditions across the inner mountain west to the west coast. And the precipitation looks a lot more above normal and uh healthier rains across the southern plains, the front range all the way down to the southeast. And these are areas that desperately need the moisture. So hopefully we can see that going through the month of May.

[00:11:34]Otherwise, a little bit drier for the Pacific Northwest, the Great Lakes, and southeastern Canada getting a little bit more dry time. So the flooding isn't as big of an issue into May. We can dry things out and the farmers can get things planted in the fields. Those corn and soybeans need to get planted here in the next few weeks obviously. So that will open up a window for the farmers as well. Thanks for watching folks.
