BILLINGS- It is another hazy, smoky type of day out there in Billings. It’s kind of a combination of stagnant air mixing with smoke creating a haze.

Although the early afternoon temperature in Billings is 81 degrees under a mostly sunny sky, once you get above the haze.

Our thunderstorm outlook for Monday shows only a few isolated showers possible in the extreme northwest corner of the state today.

That’s where the jet stream is tracking across northern Montana Monday and up into Canada.

Everywhere else in the state, we have mostly sunny skies and very comfortable temperatures, mostly into the 70s and 80s.

Our high-resolution forecast model does shows a southwesterly flow of air coming up the other side of the Beartooth Mountains.

Once those winds blow downslope, they have a tendency to compress the air that’s here and heat it up, warming us while drying up any available moisture there could be for making rain.

By 6 p.m. Monday, those downsloping winds will evaporate moisture coming over the mountains and Billings will be dry once again.

By 6 p.m. Tuesday, those southwesterly winds will be working with southeasterly winds taking any showers in the mountains and pushing them up and around south-central Montana.

Temperatures will continue to stay into the 80s throughout the rest of the afternoon and cool down to the 50s in the morning and get back up to 69 by Tuesday afternoon.

In fact, we will top out at 75 degrees on Tuesday and stay in the mid-70s throughout the rest of the week and cool down to 65 on Sunday.


TONIGHT: Mostly clear and mild. Northwest winds 10 to 20 mph. Low 51 degrees.

TUESDAY: Mostly sunny and cooler. Southeast winds 5 to 15 mph. High 75 degrees.

WEDNESDAY: Mostly sunny and continued mild. Northwest winds 5 to 15 mph. High 76 degrees.
