There is no new snow. Temperatures this morning are in the teens and low 20s F. Winds are blowing 10-15 mph out of the west and northwest (a little stronger in Hyalite).

The weather today will look a lot like yesterday. Temperatures will be quite moderate, with highs in the 20s and 30s F. Expect mostly sunny skies around Bozeman and Big Sky with more clouds as you head south. Winds will be moderate and westerly.

Snowfall will begin tomorrow, favoring the Cooke City and Island Park areas.

This morning, winds are generally light (5-10 mph). Except for in the Bridger Range, where they picked up overnight and are blowing 20-25 mph out of the west, with 40 mph gusts. There is no new snow. Temperatures are in the teens and low 20s F. 

Today will have generally calm winds (again, excepting the Bridger Range, where moderate west winds with stronger gusts will continue). Temperatures will rise into the high 20s and low 30s F. Skies will be mostly sunny in the north, with increasing clouds as you go further south in our advisory area. No new snow is expected.

Ridgetop winds in the Bridgers and Hyalite are blowing 10-14 mph gusting 20-32 mph from the W. In all other areas, winds are blowing 5-10 mph from the W & NW. An inch or two of snow fell overnight.

Today expect mostly cloudy skies this morning with a few snowflakes in the air and maybe a little clearing this afternoon. High temperatures should be mostly in the mid 20s F. Winds will be light in most areas but will blow a bit stronger in the mountains near Bozeman this morning.

Note about winds - Friday should have mostly light winds. On Saturday, winds pick up  in the mountains near Bozeman, and on Sunday winds from the SW crank up for most areas. There is tons of soft snow available for the winds to transport

Yesterday some snow fell in most areas with the mountains near Big Sky and Bozeman getting 2-4 inches. Further south a trace to 2 inches fell. More importantly, the strongest winds blew yesterday morning to midday from the NW at 15 mph gusting to 40 mph.

This morning temperatures are hovering near 10 degrees F. Winds are blowing 8-18 mph from the W and NW gusting in the low 20s. Skies are mostly clear.

Today clouds will increase as moisture moves over the area. Temperatures should warm into the low 20s F. Winds will slowly shift direction and blow from the SW but not increase in speed. Tonight a few more inches of snow should fall.

WIND is really driving the avalanche danger now (especially with so much powder available to drift) and it looks like we’ll have a few days without much wind. Strong winds will blow in northern and central Montana tomorrow and Friday which could affect the Bridger Range. Otherwise, the next significant wind may not arrive until Sunday.
