BILLINGS — Mostly cloudy skies are to the west of Billings Friday. That’s where all the rain is just on the other of the Yellowstone County line.

Copious amounts of rain continue to move from south to north out of Wyoming into south-central Montana.

However, so far, that line of showers is just to the west of Billings and continues to move very slowly to the east. This is why we remain pretty much dry Friday.

In the early afternoon, the temperatures continue to remain cool. It is 57 degrees and mostly cloudy in Billings.

Out in the west, temps are really cool. The Southwest is into the 40s at 1:30 p.m. It's 50s and 60s are along the Hi-Line and eastern Montana. That's where the hot stuff is, 68 at Miles City and 70 in Glendive.

Our thunderstorm outlook for Friday shows isolated thundershowers from Bozeman to Billings up the Glasgow, while there is a marginal risk for severe storms just the South and East of Billings and all the way to the southeast corner the state.

We have an increased risk of severe storms in the extreme southeast corner of Carter County in southeastern Montana.

Right now, the Doppler radar shows most of the heavy rain and snow showers continue to move straight out of Cody and head due north on a direct line toward Havre, staying just west of Billings.

The high-resolution forecast model shows most of the rain and snow continue to stay there in the early afternoon.

But by 6:30 p.m., a band of heavy showers and thunderstorms will continue to move over Stillwater, Sweet Grass and Big Horn counties and smack in the middle Billings in Yellowstone County.

Those showers are forecast to stay with us through Saturday morning, but tend to lighten up little bit.

And by Saturday night, the whole storm picks up and moves out of here, leaving us with mostly sunny skies and warmer temperatures on Sunday.

For the rest of the day, Billings will cool back down from 60s to maybe 51 degrees in the morning then back up to 59 degrees about 1:30 p.m. Saturday afternoon.

We will actually top out at 64 degrees on Saturday and work our way up to the mid-70s, by Sunday through Tuesday and then back down into the 60s Wednesday and Thursday.


TONIGHT: Mostly cloudy with a 100% chance for showers and thunderstorms in the evening the evening and again overnight.

SATURDAY: Decreasing clouds with a 60% chance for rain in the morning and a slight chance for showers in the afternoon. West winds 15 to 25 mph. High 64 degrees.

SUNDAY: Mostly sunny and a little but warmer. Southwest winds 10 to 20 mph. High 74 degrees.
