May 27th, 2026 - 70s Lakefront, 80s Inland for SE Wisconsin #wiwx

Added: 2026-05-28

[00:00:01]Hi guys, meteorologist Lindsay Slater here. So, let's talk about today. We did hit that high exactly of 86 degrees yesterday. I keep a record of my forecast. I know this is backwards. I keep a record of my forecast and how I did basically and got it on the money.

[00:00:17]Sure as heck that didn't happen last week. There was a day I forecasted 56.

[00:00:20]We hit 50 because of the lake. And that is my point for today. The lake breeze is kicking in. And that lake is going to be allowing for us. The lake right now is still sitting at 48 degrees. So any wind that's coming off that lake is going to be cold. Okay. So we're going to be a little cooler near the lakefront. If you get to like Brookfield, you're probably going to be much warmer. I would say low 80s. So uh we do have this stationary boundary that's just hanging out. Remember I talked about the backdoor cold front. So that's still happening. This boundary will turn into a cold front later today.

[00:00:51]If you notice this little dashed line right here, that is actually what we call an outflow boundary. So, let me show you here as I draw. So, this frontal boundary eventually will be turning into our cold front later today.

[00:01:05]This dashed line is basically thunderstorms that have now passed and there's just leftover basically showers and a couple of storms that are exceeding the actual frontal boundary. We call that an outflow boundary. So sometimes outflow boundaries can get pretty sassy, but in this case, um I don't believe it's still causing a lot of issues, but you still can get damaging wind gust. You can get lingering flooding going on. So something that I think we should be aware of. If you see that dash line, sometimes this actually, you know, it actually does say something like outflow boundary next to it, but in this case, it does not. However, very interesting to see. I do want to show you the radar.

[00:01:45]I think that would probably actually you know what I have G I subscribe to GR2 analyst that's or GRE GRE earth which is my favorite platform to assess energy you can see all the energy coming in from the Gulf it's not just about it being hot cape is actually convective available potential energy is also a function of how much moisture is in the atmosphere to give a better chance for showers and thunderstorms to get spicy as I like to say or sassy um and you can already see that coming in from the Gulf That's why the Gulf typically is has had these incredible cave values, but that's surface space cave, mid and upper level cave. I mean, we're talking 4,000 cave.

[00:02:23]That's quite impressive. So, none of that's here. Um, the radar, I think the leftover outflow boundary is almost gone at this point. So, I don't see it here on the radar at all. This could be a little bit of leftover outflow stuff as well because storms happened in like Apple yesterday, Green Bay, and they kind of worked their way down. We didn't get much of that activity. Um, what I can do is I can pull I can pull up the let's see the Mosaic loop. And I love this website. It is from Mezone.

[00:02:52]Mezoneet, excuse me. And had a little hiccup. Um, basically Mezzonet. What's What month are we in? We're in May and yesterday was the 26th. So, what I can do is I can basically verify what happened yesterday. And you can see there are some of those showers and thunderstorms associated with the backdoor cold front. And I mentioned that front was likely going to stall and then continue today. As it continues today, we have a better chance of seeing some a couple of showers, maybe a few thunderstorms. But you can see as we get to the overnight hours, no energy or basically all the energy. I'm going to stop it here so I can point out a feature. The energy basically just got zapped. So you can see these storms were hot and heavy for a while and then they started eroding. Nothing left to work with. The frontal boundary didn't do much. This right here is a leftover outflow boundary. You can see based on the curve there. So, those are showers and storms that have continued up ahead of the front. Here's another one right there. And also right here that basically can sometimes show you where convection aka showers and storms will initiate the next day because that boundary is still there.

[00:04:01]So, right now you have a leftover boundary that's hanging out. You have one right here and you have one right there. And so today, this is likely where storms are going to form. I'm going to verify that by showing you the weather models and how it initiates that convection. Um here's a look at the latest. I'm going to load it a little bit later so you can see some of the eroding showers and storms. And that boundary is still here. So Iowa and also in Wisconsin, there's likely going to be something happening here later today.

[00:04:34]bigger weather system down to the south.

[00:04:36]Oh, wow. That was a really cool feature.

[00:04:37]If you look right here, right there, that little storm.

[00:04:41]Look at that guy. Just wow. Sorry, my phone keeps going off. I'll make sure that it's uh not making so much noise.

[00:04:48]So, that's something we'll be watching.

[00:04:49]Here is a look at where that boundary is sitting basically right now. Um, you can see it right there stretching from basically what like north central or I'm sorry, east central Minnesota kind of a little bit above 94.

[00:05:04]So there's 94. It going goes all the way into basically northern Shboen County.

[00:05:09]So this is where I would anticipate storms to fire later today. Um, here's a look. You can actually see how much warmer that boundary or this air is because this is cooled air from the rain they had last night and now we have some warmth cooled air from the rain last night. So yeah, areas that didn't get much in the way of rain. Probably didn't really see a lot of cooling going on.

[00:05:29]Temperatures right now are sitting near 59 degrees. We're going to see that go up as we go through the day. Today it is going to be cooler near the lakefront.

[00:05:36]This is a graphical forecast from the weather service. And if I zoom in the map, you can clearly see the coolness near the lake versus if you just go to like Brookfield, you can see some warmth. I don't know why that little box is there. You can see some warmth. I mean, that is the difference. You know, that's like probably 70ish degrees and then you have 81 in FondeLac and you have likely 75 just to the west of Shboen. So, I love showcasing the graphical forecast when I can because you can clearly see that the lake still has an influence this time of the year.

[00:06:08]Um, speaking of the lake, we do have some swim risk issues. Now that Memorial Day has passed, the beaches are officially open. You can go to the DNR website to track that. Um, Wisconsin beaches, if you are to click, you can actually click on different beaches from the DNR to check the beach health. I think that's a great idea to do because quite frankly, you don't want to go and plan your whole day around. Yeah, we're going to go to the beach today and then you go to the beach and it's closed because of bacteria or something. So, I love this advisory website. You can zoom into the beach that you want. It'll populate here in a second. But you can see that little triangle, upside down triangle that basically showcases there's some kind of an advisory. So, green means that it's open. You can click more on it. So I can click on McKinley right now. It says it's open and then you can click on it and it'll tell you things about it. So it does look like on May 23rd there was some E.coli issues but the uh criteria was not exceeded. So they did not have to worry about, you know, having an advisory on that beach. Um but if we go to this one, Bradford, this was also elevated bacteria for the 23rd. That's not today. Today's the 27th. So it just kind of shows you the health of the beach. and they all look really good, which is great. Um, you can go back to that beach state beach advisory reports, monitoring questions, reasons for advisories and closures. I think this is just a great website and the DNR does a great job showcasing what and how they issue these uh alerts so that you don't plan your whole day around going to Bradford Beach and then find out it's not open. So, wanted to put that out there. We do have high swim risks for tomorrow. So, tonight and tomorrow, uh, likely because of that backdoor cold front moving through. You probably don't want to go to the beach anyway tomorrow because it's going to be 66.

[00:07:58]Seems a little chilly. Plus, the water is 48. But you know what? There are people that surf in Shbboan at those beach at those waves and those beaches when it's like middle of winter. To each their own. But yes, there is going to be high swim risk mainly due to the fact that the temperature low 40s. We also have sunny conditions, but those waves are three to five feet. So that could definitely make things a little tough.

[00:08:22]Um, so high swim risk. I don't know if the beach is closed closed because of those high swim risks, but it is something that I want you to be aware of. All right, let's talk about preip in the forecast. We're talking about that backdoor cold front and look at that.

[00:08:37]See where the initiation started?

[00:08:40]Yep, that's that leftover boundary. So now we watch that area as we go through the day.

[00:08:45]And boom. See that science? Exactly where I mentioned it would be because if you go back to the model, that's where we had the activity last night and it just kind of faded away. So that boundary still lives there. Now we go later on in the afternoon. Now we're into this is 3:00, four, five, six. And you can see actually that's seven. And you can see that activity is now in the same area.

[00:09:11]And that will likely push its way. I would say 9:00 in Milwaukee is the best option. It really fizzles. High pressure takes over and it fizzles. Doesn't have a lot to work with. I mean, it's a it's an old boundary and that cold front just passes through and then high pressure takes over. It's like, "Hey, I'm here."

[00:09:26]That high pressure stays a while. My 7-day forecast is boring, which means you're going to have a wonderful time with it. Um, I'm going to pop up here the GFS. GFS also has the feature, the little bits right there. See that little bit? It has a little bit more of it, but yeah, you can see that we do have that boundary and then it kind of pushes through and you're done right there.

[00:09:48]After that, high pressure moves in and that high pressure is staying put. There are systems all around us moving through, but nothing actually comes back here until potentially.

[00:09:59]I mean, we get to Monday of next week. I mean, it's a maybe chance as we get a low moving through, but then high pressure returns.

[00:10:07]There's a lot going on on the east coast and to the west of us, but we're in this omega block pattern, which I talked about in a previous video. And yeah, that high pressure just stays stays tight and it doesn't really allow for a lot of activity to be here. In fact, my whole 7-day forecast, minus tonight, doesn't have any rain in it. And you can see that omega blocking pattern by just looking here. I mean, it's a little bit skewed looking, but you see it right there. Boom, boom, boom, boom, boom.

[00:10:33]heat for the central United States all the way up into the Midwest. Um a cool and and stormy conditions for the West Coast and the East Coast until that block breaks. And it's still very present going into much of June. So, all right, let's talk some graphics that I made for you guys today. And these graphics do include one of my new favorites. It's a plant cast because I know people have plants and the rain chance is pretty low. So, watering your plants is a yes. I would water that garden, water that lawn. The little bit we get tonight is like 210 of an inch. That is not enough. My grass is hasn't really grown very much, which I appreciate the less one less chore to have to do. But yes, plant cast today.

[00:11:17]Definitely do some watering. Um the swim risk that's for tomorrow. Today it's low, but tonight and tomorrow throughout the lakefront regions are going to be high due to those 3 to 5 foot waves.

[00:11:28]Mocast for the next three days looks fine because the rain chances are overnight. No issues there. Brewers play today. It's a 1240 game. We won yesterday again. So let's, you know, get another W on the list here. Temperatures are going to be cooler. So maybe a more pleasant game for you as uh we do have first pitch is 76 degrees. Uh at a glance forecast. I like this one. It's kind of a new one in my arsenal. Temp today 77, due point 52. So, it's dry.

[00:11:55]Um, due points getting into like the 60s. You'll notice it being muggy and then once we get to like 70s, that's when it becomes unbearable. UV index is moderate to high today. So, grab the sunblock and air quality is good, which we like. Here's a dupoint forecast. As I mentioned, it's pretty low. I can't even add it to my little map here graphic because it goes into the 40s for the next four days. So, heads up on the due points. And what else did I have for you guys? Rain chances are low. Oh yeah, 7day. Where are you? There you are.

[00:12:26]There is your 7-day forecast as I end this video today. Lot of sun on that one. The next best chance would be Monday for any rain, but I just the GFS puts it in there, but nothing else does.

[00:12:37]So, I'm going to keep it sunny for now, but we're getting warmer uh through the weekend, and we're going to maintain some of those 70s. Next Wednesday, I have a high of 83. So, we'll likely see some warming continue to happen as we round as we go into June. I would say second and third, you're going to notice a pretty big warming trend. So, you guys have a good day. I'll see you Friday. Or wait, what's today? Wednesday. I'll see you Thursday.
