Record heat - Monday evening forecast

Añadido: 2026-05-12

[00:00:00]Take a look at your weather and focusing on watering your lawn. Now, we showed you this last week where this is the watering guide up through May 15th where most of northern through northeastern Utah, the recommendation is you don't water your lawn. But again this week with these hot temperatures in place, the temptation is there. We need to be mindful, yes, if we're going to water our lawns, do it in the early morning hours. But also we should be looking at where temperatures are at where it's been 90s here today through tomorrow as well. I would delay watering the lawn where here across northern Utah, temperatures are going to be dropping it back into the 70s. Good opportunity where was we take a look at the evaporation rate of that water. For instance, if we're in the low 90s versus the low 70s, that evaporation rate doubles. So this is a situation where yeah, the timing of the day, but also look at the days of the week where we do have some cooler temperatures which we're going to get that a little bit later on in the week. Right now though, it's just all hot here all throughout the state. St. George at 98°. You've got the sunshine, some high-level clouds, but some haze in place. We've been talking about air quality diminishing with this high pressure in place. The air is just stagnant, it's not moving, we're not mixing out. Where as I said, specifically looking towards Davis, Salt Lake, Tooele counties right now in the unhealthy for sensitive groups. And it's really ozone that's driving the concern with the air quality right now. I don't see much improvement at least up until Thursday before a cool front moves in.

[00:01:22]So tomorrow, expected high 93°. You can see we're looking at another day breaking records where we broke the record today at 92°. Now, I mentioned that cool down, not so much tomorrow.

[00:01:33]And then heading into Wednesday, we're going to be hanging on to low 90s here along the Wasatch Front, but a little bit cooler as we look towards St. George. And then we start to see a drop as we go into Thursday here across the state where high pressure in place, a few high-level clouds, but again we're keeping the moisture away. There'll be moments of some clouds as we take a look at our computer models waiting for the arrival of this next cool front. So as we go into Tuesday, sunny day, mountains maybe seeing some cloud cover. Oh, we can't rule out maybe a very isolated shower near the Utah-Idaho border. Then we start to bring in that flow out of the south, some cloud cover in place, front on its way. Now, as we look at the situation, this next front is going to drive in a little bit of moisture. We're mainly looking at some mountain showers there as we go in late Wednesday night and then overnight Wednesday through Thursday, front moves in and then that moves on, which means we're going to still see a lot of sunshine, but temperatures noticeably different where we're going to see almost about a 20° swing. Now, as we see for tonight, it's mostly clear, overnight lows in the upper 50s, so cool enough that again you can open up your windows, allowing that cooler air to track in, where tomorrow it's a once again very toasty here across the state as we're seeing 90s for many locations and triple digits in St. George, but again we drop back down into the 90s and stay there as we look even from the weekend into the beginning of next week. Now, for northern Utah, you've got the heat record-breaking tomorrow, close to record tying on Wednesday, then it's 70s, 80s, and then 60s on Sunday. So, you like the trend.

[00:02:58]Again, this is when you should water your lawns when we do have some cooler temperatures, but for the next couple of days, we're hanging on to the heat.
