CHEYENNE, Wyo. (Wyoming News Now) - High pressure remains the dominant feature which will continue to bring those warm and dry conditions as well as some strong winds to our state over the next several days.

Today we definitely saw the by-product of that a little bit. We had some toasty temperatures today and our highs all over the state were a bit higher than what we have seen over the past couple of days -- 80s and 90s were the most predominant with Afton and Yellowstone standing alone in the 70s.

Smoke will be swooping in from the north and northwest and we will see many states experiencing heavier smoke into the overnight hours of tonight and into early tomorrow morning. That smoke will continue to head south, though, clearing up the air a little bit in northern Wyoming and settling in the central and southern regions. However, by Wednesday morning, things will start to look good for the eastern and northern regions as that smoke clears from those areas and settles along the western quarter of the state.

Smoke will be heading south, clearing up the northern border and then settling in the west.

Unfortunately, those warning and alerts have returned in full force. We have air quality alerts and red flag warnings covering most of the state. Our fire outlook is elevated for a majority of our state and critical in the central region around Rawlins, Riverton and Casper.

Air quality alerts are present over most of the state and there are even fire weather warnings covering most of the state as well that expire at 8pm tonight, but we expect to see an extension on that as the night goes on.(Rachel Saurer)

We’re currently seeing the end of a shortwave trough which has been to blame for a lot of the strong winds and some upper altitude clouds that made their way into the state early in the evening. You can see we are clearly dominated by a high pressure system which will continue to provide us with warm and dry conditions and we will see those temperatures steadily increase throughout the week. Something worth watching will be some possible record breaking highs into the middle of the week, and we’ll keep you updated on the occurrence of those. We’re also keeping an eye on the northern fronts and we will eventually see a cold front making its way from Montana and into our state later on.

A trough is moving out of the state giving us some higher winds and we are dominated by high pressure systems so we will be seeing clear skies and warmer temperature moving foreward.(Rachel Saurer)

Satellite and radar shows those upper level clouds driven by that shortwave trough making its way into the northern part of the state. Those will all quickly pass into the overnight hours if we look at our predictor, leaving the state with relatively clear skies and a better chance for some radiational cooling, which will be a nice reprieve from the warmth we experienced today.

As we can see from our wind predictor, we experienced a weak cold front from the north this afternoon that fueled those winds and we saw those increase throughout the day. However, those winds will start to decrease heading into tonight and remain fairly steady into tomorrow.

Wind speeds will be increasing heading into tonight, and then start to decrease into the...
Wind speeds will be increasing heading into tonight, and then start to decrease into the overnight hours. Then, they will remain pretty steady into Tuesday.(Rachel Saurer)

Tonight, we’ll see 50s and 40s all across the state, with a pocket in the northwest cooling down into the 30s. We’ll be also cooling by a couple degrees tomorrow thanks to that weak cold front that managed to make its way in and we will see mostly 80s and a couple 70s in that northwestern corner.

As mentioned before, those high pressure systems will continue to keep things quiet in the long run and we even have the opportunity to witness some record breakers over the next few days.
