Over the past 24 hours a cold northwest flow dropped a trace to one inch of snow in the northern Gallatin and Madison Ranges. This weak system has been pushed to the east by a building ridge of high pressure, which is producing clear skies and relatively calm conditions.
Currently, mountain temperatures are ranging from the high teens to mid twenties and winds are blowing out of the WNW at 5-15 mph, with the exception of the Bridger Range where ridgetop winds are blowing 25-35 mph. Today, skies will remain clear and temperatures will climb into the low 30s F. Winds will gradually increase through the day, blowing 20-30 mph out of W. Skies will become partly to mostly cloudy by this evening as the next weather system approaches from the west.
Montana is currently positioned on the leeward side of a ridge of high pressure sitting off the coast of California. This is generating a northwest flow over our area, producing mostly cloudy skies and cool temperatures. At 4 am this morning, mountain temperatures are ranging between 10 and 15⁰ F with Cooke City weather station being the coldest at 3⁰ F. Winds are averaging 10-20 mph out of the WNW with the exception of the Bridger Range where ridgetop winds are blowing 30-40 mph out of WNW. Today, temperatures will climb into the mid to high twenties under partly cloudy skies and winds will continue to blow 15-30 out of the WNW.
MOUNTAIN WEATHER
A dry cold front moving over southwest Montana is currently producing mountain temperatures in the low to mid teens. Winds are blowing out of the WNW at 10-15 mph. Very little moisture is associated with this front, but a trace to one inch of snow is possible in the mountains by early afternoon. This front will exit the area by mid day allowing temperatures to rise into the high teens to low 20’s under partly cloudy skies. Winds will remain out of the WNW at 10-15 mph.

A resident of Cooke City hiked into Hayden Creek yesterday and confirmed that Ole the dog survived for 4 days buried 3ft deep. He likely heard Doug and Karl walking on the debris conducting the accident investigation while he was still buried. A video was posted documenting this tale of survival.
This morning temperatures were in the 30s F and winds were averaging 15-30 mph from the W and SW gusting 35-50 mph. This morning will remain warm and windy. Clouds will move over the area and by afternoon bring cooler air which will keep temperatures in the 30s F. Winds shouldn’t ease until this evening, and some areas could receive a dusting or even an inch of snow by tomorrow morning.
AVALANCHE INCIDENTS
We have posted many photos and several videos from the two avalanche fatalities outside Cooke City. Full reports will be made public later this week.
Good news: In the avalanche in Hayden Creek south of Cooke City, a dog (a Corgi) was caught and presumed to be buried and dead. However, yesterday afternoon this dog appeared at the Antlers Lodge outside the hotel room where the victim and his wife were staying. Residents of Cooke City helped reunite this dog with its family.
Yesterday, under sunny skies, mountain temperatures hovered in the high 20s except in the Bridger Range where they hit the mid 30s.

Temperatures, however, will approach their record highs and near 40F in the early afternoon.

We have posted many photos on our website from the two avalanche fatalities outside Cooke City. We also have two video clips of our investigations posted:
- Henderson Mountain avalanche involving a snowmobiler (video).
- Hayden Creek avalanche involving a skier (video).

Full reports will be made public later this week.
Yesterday was sunny and unseasonably warm with high temperatures in the Bridger Range reaching 45F. Other mountain areas had temperatures in the high 20s to low thirties. Winds blew hard out of the west to southwest with gusts hitting the 50s, but have lessened overnight and will die down even further this afternoon. Today will be more of the same: sunny and mild. This pattern of high pressure looks to stay with us through Thursday.
A building ridge of high pressure will bring sunny and unseasonably warm conditions to southwest Montana today. Currently mountain temperatures are in the mid twenties to low thirties with the exception of the mountains around West Yellowstone and Cooke City where temperatures are in the mid teens. Winds are blowing 10-20 mph out of the WSW and will gradually increase to 15-30 mph by this afternoon. Clear skies and warmer temperatures are expected through tomorrow.
Yesterday was a beautiful sunny day, and so will today.
