CHEYENNE, Wyo. (Wyoming News Now) - Today brought back weather that we haven’t seen in a hot minute, thanks to a cold front coming through which gave us some pretty seasonably cool temperatures lately. But for now, summer is back -- at least for today and tomorrow until a trough comes in and gives us another opportunity for a cool down.

One a positive note, the smoke is beginning to clear little by little. By tomorrow afternoon, we’ll start to see a nice clear pocket open up over the northwestern corner of the state. As we head into tomorrow night, that pocket will shift and start to move south where the southern border will see some nice clear skies. Then, by Monday morning, that smoke will disperse a little bit and the southern half of the state will start to see some slightly heavier smoke with the upper regions clearing out a bit.

We can expect these warmer temperatures to persist in the southeast corner until the that trough sweeping over half of the state starts to move east. We can expect some cooler temperatures from this trough as well as some chances of precipitation. Rain can be expected in the lower regions, with some snow in the mountains. The northern parts of the state can expect to see some snow as well. Also, with this trough movement, we can also expect to see some strong winds with gusts up to 30 plus miles per hour and sustained winds around there as well heading into Sunday night.

As that trough moves through, we can expect to see some thunderstorms, and the SPC issues a general thunderstorm risk for the western side of the state, with a marginal risk over the southwestern corner around Evanston.

Tonight’s lows are going to be brisk, but we will be seeing some even cooler temperatures over the next few days.

It will be getting chilly tonight, but it will be becoming even cooler as the days progress.

The highs on Sunday will be a bit cooler for some of the state, and more an extreme change for other regions around Wyoming. Yellowstone and Jackson are going to be very chilly, with highs in the 40s. That’s where we can expect to see some of that snowfall -- but it should just be a couple inches in those areas.

The extended forecast for Cheyenne shows that we will see more seasonable and fall-like temperatures return later in the week with highs in the 60s and 70s. Casper as well will be cooling down a little bit, but not too much. Just enough to give them a taste of fall.
