BILLINGS — On Monday, Billings woke up to cloudy skies and warmer temperatures. In the early afternoon, the temperature in Billings was already up into the upper 60s.

Around the rest of the state, we see 50s and 60s in the west with most of the 70s back in the east. However, we do see places like Great Falls, Lewistown and Billings all in the 60s.

The big story Monday is the thunderstorm outlook. It shows a marginal risk of severe thunderstorms in west-central Montana between Missoula and Bozeman, all the way into Great Falls and Havre. On either side of that, we see non-severe thunderstorms possible.

On Tuesday, everything shifts a little bit with an elevated risk of severe storms in north-central Montana a marginal risk of severe storms all around that and isolated thunderstorms beyond that.

In the Billings area, we expect isolated thunderstorms with the severe stuff a little farther to the north and west.

The Doppler radar shows most of the rain continuing around Missoula up to Glacier National Park, with just light to moderate rain.

Later Monday night, the high-resolution forecast model shows the big stuff will to be moving into the Missoula area about 5:30 p.m. and then continue to track on in the Canada.

On Tuesday afternoon, we see more showers and thunderstorms stream into western Montana and heading into the north-central part of the state. Here in the Billings area, we are expecting mostly dry conditions, with most of the heavier storms out in the West.

Our temperature next hour gets back up into the mid-80s and stay there through 6:30 p.m. then cool back down into the 50s in the morning, then and back up to the 70s early Tuesday afternoon.

We will top out at 84 on Tuesday, then roll it back into the 70s on Wednesday Thursday and Friday and into the 60s over the weekend.


TONIGHT: Decreasing clouds and mild. Southwest winds 5 to 10 mph. Low 54 degrees.

TUESDAY: Mostly sunny with a 20% chance for showers and thunderstorms in the afternoon. West winds 5 to 10 mph the morning shifting to the East at 5 to 15 mph in the afternoon. High 84 degrees.

WEDNESDAY: Partly sunny with a 40% chance for showers and thunderstorms in the morning and then again in the afternoon. West winds 5 to 15 mph. High 76 degrees.
