A temperature inversion or 'cap' of warmer air at altitude prevents thunderstorms from developing severe weather by dissipating rising air before it can intensify, as demonstrated when storms formed but weakened due to this atmospheric layer.

Warming trend ramping up with a few t-stormsAdded:
Here's First Alert, Chief Meteorologist Dave Aguilera. You know, earlier you promised to keep your eyes on the skies all day today.
>> I'm doing it. Yeah, all through the night because we may have some storms linger until about midnight tonight the way things are looking. We really dodged a bullet today. There were some storms blossoming up, but at altitude we had warmer air. Joe Ruck talked about the cap. It's warmer air at altitude. So, we need that rising air to continue to go up in the colder air, but once it hits that warm cap it just kind of dissipates and that's what happened today. Although we did see quite a bit in the way of rain in some locations and some very small hail, but nothing too severe.
Let's take a look at the radar now and this shows on only thing we got working is Southern Douglas County into the northern part of Teller County. Let's zoom into that and I'll show you that storm. It spreads from Castle Rock all the way down through West Creek and the northern part of Teller County little bit heavier there, but that will be moving into Douglas County. Castle Rock, Castle Pines, and Parker just had a couple of storms go through and as you look at that you can see those storms are weakening. Now we just have a pretty good rain shower in the central part of Douglas County. We've also had some storms down in southern parts of our state here over the Sangre de Cristos down into southeastern Colorado. Same thing there, nothing severe as of yet.
So, that is good news. Let's walk you through the forecast for the night now with the future cast here. Most of what we have going on will start to move out of the area, but as we go through the night. This is 11:30 tonight. We could have a few thunderstorms still coming through the metro area here all the way down south. So, it may be a night where the rumbling of thunder might wake you up especially if you go to bed early tonight. Tomorrow partly sunny skies again here across the east mix of clouds and sunshine little sun in the middle of the day and that should be enough to heat up the atmosphere and get some more thunderstorms going in the mountains and across the eastern plains. So, east of I-25 a few of these storms could be large or severe coming up for tomorrow.
So, that whole area tomorrow just outside of DIA and the Eastern Colorado up towards Greeley has the chance of damaging winds and large hail. And you can see Denver is pretty close to this, so I wouldn't be surprised tomorrow if the National Weather Service extends that back into Denver and we might have to be on the lookout for more severe weather again tomorrow. Things will calm down though by the time we get to Thursday, Friday, and the weekend.
Overnight tonight 50s and 40s down low will be in the 40s and 30s in the mountains and highs tomorrow lot of 80s here across the Eastern Plains, 70s and 60s in the mountains and maybe a few 80s. For example, 77 in Vail, 80 in Aspen, Leadville at 68, and 80s and 90s out there on the Western Slope. It is going to be hot in Grand Junction tomorrow about 92. So, if you are up in Wellington tomorrow, you'll be about 83, down in Castle Rock right around 80, Aurora back up into sections of downtown Denver, Lakewood right around 83-84 degrees. In some of the neighborhoods of Fort Collins in our neighborhood network here, Fossil Lake, Foxstone, Lake Sherwood, University Acres, all the way up to the CSU campus right around 84 degrees it looks like. And a quick look at what happens for the weekend, we've got this little trough here that's allowing the moisture to come in for thunderstorms each day, but watch what happens. Once we get into Saturday, Sunday, bam, a huge ridge of high pressure comes in and we have some of the temperatures over the weekend into next week that may be up in the 90s. So, let's roll through that. 83 tomorrow, scattered storms.
Thursday, 89, almost 90 and just a slight chance of a late day storm. Dry on Friday at 89, 92 on Saturday, and Sunday there's a slight chance of a late day storm, but we still make it to 92 and we keep it in the upper 80s to near 90 all the way through the end of next week. Here comes summer, it's ready to take over.
