CHEYENNE, Wyo. (Wyoming News Now) - Very similar weather will be occurring today and tomorrow due to the high pressure system currently dominating our state. We saw above average temperatures today, but they ranged anywhere from upper the 60s to low 90s. We also saw some pretty strong winds head through our area as well prompting some fire weather watches in some places.

Even though we are experiencing clear skies as far as clouds go, haze has made a comeback. That heavier smoke has returned and we will see it sticking around at least through Tuesday, which as far out as our models go. A heavier pocket from the west crept in last night and it will continue sweeping in and getting heavier by tomorrow afternoon. So, we can also expect some air quality alerts to return for Monday.

Smoke will start coming back into tonight and early tomorrow morning.

As far as those alerts go, we have a small area of the state with an air quality alert, but it is too small a region to be too concerned with yet. But, certainly we do have fire weather warnings in effect until later this evening in the southeastern region of the state due to these seasonably high temperatures and strong winds.

Cooler temperatures and even some rain can be expected later in the week thanks to a cold front coming from the northern pacific region. It will slowly be moving east and it will reach our state by Tuesday. Cheyenne will see some possible showers on Tuesday with Casper not too far behind. We can expect to see some isolated showers Tuesday afternoon, but the chances are higher into those overnight hours and on Wednesday when that cold front is expected to pass through our state. The mountainous areas can even expect to get a few inches of snow from this system. But until then, weather will be fairly quiet.

Overnight temperatures will be slightly cooler tonight than they were last night, with 50s, 40s, and some cities hitting those low 30s. Tomorrow will be a little bit cooler, but still well above average. Thankfully, our winds speeds will taper off tomorrow so we can expect just some light breezes for the start of our work week.

We will be continuing that trend of warm and quiet weather.

If we look ahead at the extended forecast, we can see exactly when that cold front will be heading into our region. There is a potential 10- to 20-degree difference that we can see, along with some precipitation potential. For the next week after Tuesday, we will be seeing those seasonable temperatures return.
