This morning in the northern areas near Bozeman and Big Sky, mountain temperatures were in the low 20s F and winds were blowing 20-40 mph from the W. Further south near West Yellowstone and Cooke City, temperatures were in the low teens F and winds were blowing 10-20 mph from the SW. Today will warm into the high 20s F and winds will increase ahead of an approaching cold front. Next week may get snow every day. While no snow will fall by tomorrow morning, we will see Tom Brady and the Patriots crush the Broncos this evening.

This morning mountain temperatures were in the mid teens F except near West Yellowstone and Cooke City where temperatures were in the single digits F. Ridgetop winds were blowing 5-15 mph mostly from the W with gusts of 25-35 mph. Over the Bridger Range and Hyalite winds were blowing stronger at 25-40 mph. Today will be similar to yesterday. Under mostly sunny skies temperatures will warm into the mid 20s F. Winds shouldn’t change much and remain westerly blowing 10-15 mph with gusts of 20-30 mph. Weather models continue to show the current ridge of high pressure flattening on Sunday followed by a trough of low pressure approaching SW Montana. This trough will bring cold temperatures and some precipitation.

This morning mountain temperatures were in the low teens F except near West Yellowstone and Cooke City where temperatures were near 0 degrees F. Ridgetop winds were averaging 15-25 mph mostly from the NW. A ridge of high pressure off the west coast is affecting our weather by blocking moisture and creating a NW flow over Montana, a common pattern this winter. This ridge will hopefully flatten late this weekend allowing a chance of precipitation. Today will be mostly sunny with some clouds, temperatures will rise into the low 20s in most areas, and ridgetop winds will blow 10-25 mph from the NW. 

Everyone got an equal helping of cold temperatures and wind, but not snow.  The Bridger Range along with West Yellowstone got skunked and only picked up an inch.  The northern Gallatin Range and mountains around Cooke City got 6-8 inches while the Big Sky area and southern Madison Range got 3-5 inches.  Mountain temperatures this morning are zero to -10F with 5-10 mph winds out of the northwest, but 20 mph out of the east in Cooke City.  As the snow fell yesterday, west to northwest winds blew strong and averaged 20-30 mph with gusts over 40 mph. Today will be sunny, temperatures will rise into the teens and winds will remain calm.  The next snowfall is predicted to be…Sunday night.   

Under sunny skies temperatures reached the mid 30’s yesterday with westerly winds averaging 10-20 mph. Today will be different. A dynamic and moist cold front will roll through this afternoon bringing snowfall through tonight.  West winds have already increased to 20-30 mph and will notch higher while temperatures fall to the single digits this evening.  The mountains should get 3-6 inches by tomorrow morning; however, it’s a strong northwest flow and dare I suggest the Bridgers may get a wee bit extra?   

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.

Temperatures dropped overnight and were in the mid teens F this morning. Winds were averaging 5-15 mph from the NW with gusts of 25-40 mph. No snow fell overnight and today will be mostly sunny.  Winds will blow 10-20 mph from the W and NW, and temperatures will climb into the mid 20s F.

AVALANCHE INCIDENTS

Final reports on last weekend’s avalanche accidents are available at: http://www.mtavalanche.com/accident

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.
