Under partly cloudy skies temperatures are 10-15F in the south and 20F in the northern ranges.  Winds are currently west at 20-30 mph with gusts of 40 last night in Hyalite. Today will be mostly sunny and warm with temperatures rising into the high 30s. Winds will increase later this afternoon and high clouds will filter in. Today and tomorrow will be spring-like, but “Winter” is scheduled to return from her vacation in Boston and show up to work first thing Friday morning.

Under clearing skies mountain temperatures are a chilly 5F to 10F. Winds are currently blowing 10-20 mph out of the west to northwest except in Cooke City where they are much stronger and gusting to 35 mph. Today will warm into the upper 30s with moderate winds. High pressure will block any chance of precipitation and sunny spring-like weather is forecasted tomorrow.  The big question is, do I keep my snow shovel on my porch or my skateboard?

Winter is working hard to make an appearance. Over the past 24 hours most mountain locations picked up 3-5 inches of low density snow with the exception of the mountains near West Yellowstone which picked up around one inch. Temperatures are also the coldest they have been in weeks. At 4 am, mountain temperatures are in the single digits to mid-teens F and winds are light out of N-NW. Today, a northwest flow aloft will continue to produce light snow showers in the mountains, although no real accumulation is expected. Temperatures will warm into the upper teens to mid-20s F and winds will remain light out of N-NW. Winter will try and stick around until tomorrow then spring like conditions return on Wednesday.

Overnight the northern Gallatin Range picked up 1” of new snow while the rest of the advisory area remained dry. This morning, mountain temperatures are actually below freezing and range from the upper teens to mid-20s F under partly to mostly cloudy skies. Winds are blowing 10-20 mph out of the W-NW. Today, skies will remain partly to mostly cloudy and temperatures will warm into the upper 20s to low 30s F. Winds will continue to blow 10-20 mph out of the W-NW. No accumulating snowfall is expected over the course of the day. There is a better chance of precipitation tonight and tomorrow. The mountains should receive 1-3” of snow by tomorrow afternoon.

Spring like weather continues around southwest Montana. At 4 am temperatures range from the upper 20s to upper 30s F and winds are blowing 10-20 out of the W with gusts around Big Sky reaching 30 mph. Today, near record highs are possible around much of the region. By this afternoon mountain temperatures will warm into the mid to upper 40s F under partly to mostly cloudy skies. Winds will continue to blow 10-15 mph out of the W-NW with stronger gusts possible in upper elevation terrain. A weak storm system is approaching from the west which will produce increasing clouds throughout the day. Light rain and snow showers are possible in the mountains by late afternoon. The mountains could pick up 1-2 inches of snow by tomorrow morning.

Yesterday high temperatures in the mountains reached the low to mid 40s F, and this morning temperatures had dropped to a few degrees either side of freezing. Westerly winds were blowing 15-30 mph. Today will have more sunshine with temperatures reaching the 40s F again. Winds should ease this afternoon. Some snow should come tomorrow with cooler temperatures.

This morning temperatures were mostly in the mid 20’s F with SW winds blowing 10-15 mph gusting to 30 mph. Winds were blowing from the NW near Cooke City. Today will be similar to yesterday with mountain temperatures in the mid 30’s F and valley temperatures reaching the 50s F. Winds shouldn’t change much other than shifting a little more westerly.

Yesterday morning four inches of dense snow fell in the Bridger and northern Gallatin Ranges while all other areas picked up 1-2 inches. Under clearing skies mountain temperatures are in the low to mid 20s with west to southwest winds averaging 10-15 mph.  A strong high pressure system is building today and will block storms until Sunday. Mountain temperatures will reach 40F this afternoon under sunny skies.

This morning the southern areas have three inches of new snow around West Yellowstone, six inches in Taylor Fork and a foot in Cooke City. Snow just started falling and at 6 a.m. Bridger Bowl has an inch of new snow in addition to the inch from yesterday morning which also fell in the northern Madison and northern Gallatin Ranges. Mountain temperatures are in the low to mid 20s with winds out of the west to southwest averaging 20 mph and gusting to 30 mph. Today will remain windy at the ridgetops as temperatures climb to the upper 20s and snow falls. I expect 2-4 inches of new snow in the mountains with closer to six inches around Cooke City before skies clear tonight.

Snow started falling at 5 am this morning and the mountains have picked up 1-2 inches of new snow. At 6 am, mountain temperatures range from the upper 20s to mid-30s F and winds are blowing 15-25 mph out of the W-SW with gusts near 50 mph being recorded in Hyalite and Big Sky. Today, temps will warm into the upper 30s to low 40s F under cloudy skies. Winds will continue to blow 15-25 out of the W-SW with stronger gusts along the ridgelines. A weak storm system will continue to impact the area through the day. The northern mountains will likely receive an additional 1-2 inches of snow by this afternoon while the southern mountains will pick up 2-3 inches. Unsettled weather is likely through tomorrow.
