Another round of light rain has begun in the Billings area and much of south-central Montana. So far, Billings has measured .05 inches of rain since Tuesday morning.

More rain is expected to continue. At 2 p.m., light rain was still falling, and the temperature was 44° in Billings.

Elsewhere around the state, the temps were mostly into the 40s and low 50s in Eastern Montana, but Kalispell and Missoula had popped up into the low 60s while Cody was only 37°.

Our Thunderstorm Outlook for today does show some isolated thunderstorms are possible in the Southwest corner the state.

Meanwhile, the threat board continues to fill up with a Winter Storm Warning for the Crazy, Beartooth and Bighorn Mountains.

A foot or more is possible through Thursday morning in those locations. Plus, we have a Flood Watch for south-central and eastern Montana.

This covers small streams and rivers, but not including the larger ones like Yellowstone.

The Doppler radar shows rain continues to move into the state from northeastern Wyoming on a southeast flow.

This is the wraparound moisture from a larger low pressure cell in Colorado that slings moisture up towards Wyoming and Montana.

Our forecast model shows that rain will continue off and on in south central Montana including Billings through the rest of Tuesday and begin to dry up on Wednesday morning.

The moisture returns by Wednesday evening at 6 p.m. and is totally gone by Thursday afternoon.

The computer models estimate Billings could see another half an inch of rain and the same for Miles City, Sheridan could get another one a half inches of rain.
