BILLINGS- The sun is out Thursday, and the temperatures have already responded by warming up into the low 80s in Billings. There’s also a little haze from the Canadian wildfires out there.

The temperatures around the rest of the state are also into the 70s and 80s. It’s all the 80s in northeastern Montana. Everywhere else, the temps are still into the 70s.

However, we are already starting to see a mixture of heat and moisture come together in western Montana and that’s where we’re starting to see some splash and dash thundershowers.

On a threat board, we still have a Flood Watch for the Rocky Mountain front, beginning Thursday evening and going through Saturday morning.

We are expecting slow-moving heavy thunderstorms causing some additional flooding along the front. Plus, we still have a Flood Warning for the Teton River.

The Flood Warning for the Musselshell River near Shawmut is still in force and the Tongue River at Miles City is still in Flood Watch. But there’s a Flood Warning at Birney.

And now this. The National Weather Service says issued a Flash Flood Watch for Friday afternoon through Friday evening.

Heavy rain on soggy ground will cause widespread flooding from Stillwater County through Billings all the way down into Big Horn County and Sheridan County, Wyoming.

Here again, these will be slow-moving, lumbering types of heavy thunderstorms with a lot of rain in them.

The high-resolution forecast model shows that most of those showers and thunderstorms will be moving in and around the Billings area by about 5 p.m. Friday.

After that, we see a few isolated showers out in the western part of the state on Saturday. Billings should be totally dry that afternoon.


TONIGHT: Partly cloudy and continued warm. Southwest winds 5 to 15 mph. Low 54 degrees.

FRIDAY: Partly sunny with a Flash Flood Watch in the afternoon through Friday evening. Look for isolated showers in the morning then a 50% chance of scattered showers and thunderstorms in the afternoon. West winds 5 to 15 mph that morning shifting to the North by the afternoon. High 74 degrees.

SATURDAY: Mostly sunny with a 30% chance for scattered showers and thunderstorms in the afternoon. South winds 5 to 10 mph. High 79 degrees.
