There are some strong storm is erupting in the central High Plains this evening, will they be a problem for the Mile High City? Well, let’s investigate..
At 653PM, MT,, Denver was reporting a temperature of 85 degrees with mostly sunny skies. There was a field of thunderstorms that started east of DIA and have now shifted into Kansas and Nebraska that was appearing brightly on satellite. There is still a tornado watch in effect for far northeastern Colorado as an offshoot of this activity, though it had mostly deteriorated around Denver. Expect a few isolated cells as the cap wears down as the night cools off. .
There is a brisk northwest flow over the Rockies, which is leading to the development of a lee trough in Colorado. A surface vorticity maximum will ripple through the Front Range of Wyoming towards the northern end of that lee wave, which will help to touch off thunderstorms in what will be a juicy environment. The surface low will be too close to the mountains for any of the unstable, juicy air to cycle south to Denver, rendering the area dry tomorrow until the cap weakens and breaks late in the evening. After the surface feature moves away from the mountains on Wednesday, there will be an increase in surface upsloping around Denver. The prevailing northwesterly flow will mean a high shear environment, and while many of the storms will be high based, they will also have very tall tops, meaning vivid lightning and some gusty winds for Wednesday, even if rainfall is minimal at the back side of the surface low.

Here is the satellite, discussing those complexes headed towards Kansas as I was discussing, but since I started working on this, a couple of thunderstorms have popped up outside of town, including a severe cell east of Greeley. I should note one thing about the weather too: When you get air moving up hill, it gets HOT.
