BILLINGS — Low clouds and fog are covering many lower-elevation locations this morning. Fog is expected to thicken up before sunrise as moisture settles in, with some spots dropping to a quarter-mile of visibility or less. Take it easy on your morning drive!
Most of the area stays dry for much of the week, though a quick-moving disturbance could bring scattered showers and isolated thunderstorms Tuesday night into Wednesday morning.
We can also expect a warm-up this week with afternoon highs climbing into the 70s Monday through Wednesday before reaching into the 80s the second half of the week.
By late week, models are showing a deep area of low pressure moving through the Pacific Northwest and northern MT. If this system does develop, it could bring a cool-down and a chance for rain. Something to keep an eye on as we get closer to the weekend.
