Q2 Weather: More mountian snow and flooding rains overnight

The light rain continues to fall in the Billings area this Monday afternoon. So far Billings has measured 0.14 inches of rain and it is still coming down at 2 p.m. with 51 degrees.

The Thunderstorm Outlook for Monday does show isolated thunderstorms possible in northern Wyoming and southern Montana.

And the threat board continues to have a Flood Warning for the Bighorn River in Big Horn County Montana.

That river is running high thanks to the two to four inches of rain that fell Sunday, which is causing the Big Horn River to go out of its banks.

Plus, we have a Flood Watch until Tuesday afternoon for another possible one to two inches of rainfall in the dark green highlighted areas.

This includes Sheridan, Big Horn, Carbon, Sweet Grass and Stillwater counties.

Additionally, we have a Winter Storm Warning which remains in effect until noon Tuesday above the 8000-foot level of the mountains. There we could see eight to 15 inches of new snow.

As you can see on the Doppler radar the rain and snow continue to move out of Wyoming into south-central Montana and eventually up towards Great Falls.

This is all part of a much larger upper level low pressure cell over the great basin area and Salt Lake City.

The moisture is rotating around that now and sending it up through Wyoming into Montana and even into parts of Idaho.

Eventually that low will track into the central plains and as it does so it will take most of the moisture with it but not before southern Montana and northern Wyoming get a good drenching.

It seems like our reporting stations in northern Wyoming will catch the lion’s share of all this rain. Sheridan could pick up another 0.73 inches, Cody 0.85 inches and Worland 0.60 inches of rain.

Temperature wise we will still be comfortable at 64 for high on Tuesday, but then work our way all the way up to 80 degrees by Sunday.
