Cheyenne, Wyoming
Off we go to the capital of the least populous state in the US. For some reason, it's totally opposite of what Wyoming is best-known for, Yellowstone Park. Perhaps they just like the nightlife in Denver better.
At 7:53PM MDT, the temperature at Cheyenne was 70 degrees under mostly cloudy skies. Most of these clouds were fairly high-based and will dissipate as the evening wears on. An upper-level trough has been very slowly pushing its' way eastward over the last few days, mainly due to the overpowering ridge that's parked itself over the eastern US with triple-digit highs. This trough will continue to slowly shift its way through the Northern Plains over the next couple of days as the mega-ridge breaks down somewhere. At the surface, a stationary front has set up shop from ND through northern WY back into ID. This front, however, will turn into a slow-moving cold front as it reluctantly travels towards the southeast. As the front approaches the Central Dakotas down into southeast WY, the base of the trough will be swinging through the Cowboy State as well. This influx of energy could set off some strong to severe thunderstorms around the capital late in the day into the overnight hours. A few lingering showers could last into early Wednesday, with much cooler weather expected as a cooler airmass settles in overhead. While there will still be a chance of some scattered showers/isolated thunderstorms on Wednesday, it'll be significantly cooler. Gotta love these crazy summer months!

Here we see a deck of clouds off to the north dropping some showers and isolated thunderstorms. These will be dropping southward tomorrow and affect Cheyenne by evening.
