NWS Forecast Discussion

Temperatures dropped into the high teens last night with 1-2 inches of new snow falling early this morning.  Yesterday, under partly cloudy skies, temperatures reached the upper 40s as west winds blew 15-25 mph.  Last night as the cold front moved in, winds speeds reached 40-60 mph.  Light snow will continue today and pick up intensity tonight through Friday.  Winds will be westerly at 15-25 mph with mountain temperatures dipping into the low teens tonight.  By tomorrow morning I expect this spring storm to deliver 4-6 inches of new snow.   

Mountain temperatures reached the mid to high 40s yesterday under sunny skies. Winds have been west to southwest at 10-20 mph.  Last night was clear, but not very cold. Bridger Bowl reads the mid-thirties this morning while other areas are in the high 20s to 31F; barely freezing. A cold front is headed our way from the Pacific coast. Today will start sunny, but later this morning high clouds will roll in as winds become stronger from the southwest. Mountain temperatures will rise into the high 40s and cool off significantly tonight.  Tomorrow and Friday look to be cloudy, twenty degrees colder and snowy. 

Yesterday was sunny, but mountain temperatures only reached into the mid-30s.  Under clear skies this morning temperatures are in the high teens as winds blow 10-20 mph out of the southwest.   Today will be sunny with temperatures reaching the 50s as winds remain light.  Tonight looks to be clear and cold again with more sunshine on Wednesday.  In the valleys I’m forecasting balmy temps in the 60s along with sightings of flip-flops, shorts and pasty white legs. 

Over the past 24 hours 10-12 inches of snow fell in the northern Madison Range, 8 inches fell in the Bridger Range, 4-6 inches fell in the southern Madison Range and 1-2 inches fell in the mountains around West Yellowstone and Cooke City.  Currently, temperatures are in the single digits on Lone Mountain and 10-20 degrees elsewhere.  Winds are blowing 10-20 mph out of the WSW.  Today, cool temperatures will persist with highs reaching into the upper 20s to low 30s.  Winds will continue to blow 10-20 mph out of the WSW.  A building ridge of high pressure will produce clear and calm conditions through the day.  A warming trend will begin tomorrow and last through Wednesday.

Unbelievable!  Last night a cold winter storm dropped over two feet of cold smoke powder in the mountains around Bozeman and Big Sky.  The riding conditions should be some of the best of the year. April Fools!  In fact a warm spring storm dropped nearly an inch of rain in the northern Gallatin Range.  Most other areas picked up .2-.3 inches of rain.  Currently, mountain temperatures are in the upper 20s to low 30s and winds are blowing 20-30 mph out of the WSW with gust reaching into the 40s.  Today, temperatures will only warm a few degrees as a cold front moves over the region.  Valley rain and mountain snow will be likely through the day.  The southern mountains including Big Sky should pick up 3-5 inches of snow by this afternoon.  The mountains near Bozeman will pick up 2-4 inches.

Since yesterday morning 4-6 inches of high density snow totaling 1.2 inches of SWE fell in the mountains around Cooke City.  The Lionhead area and southern Madison Range picked up .7-.8 inches of SWE which fell as very dense snow or rain.  The mountains around Bozeman and Big Sky picked up a trace to one inch of snow. 

At 4 am this morning, mountain temperatures are in the mid to high 30s and winds are blowing out of the WSW at 20-40 mph.  Today, skies will be partly to mostly cloudy, temperatures will warm into the 40s and winds will continue to blow 15-30 mph out of the WSW.  Another storm will move into southwest Montana by tomorrow morning.  Valley rain and mountain snow can be expected through the day tomorrow. 

Since yesterday the mountains near West Yellowstone and Cooke City received 4 inches of snow, the Taylor Fork area received 2 inches, Hyalite received 1 inch, and all other areas were mostly dry.  Yesterday all areas remained below freezing except the Bridger Range which didn’t get too warm with a high temperature of 38 degrees F.  This morning temperatures in the Bridger Range were hovering near freezing while other areas had temperatures in the high 20s F.  Winds were blowing 10-20 mph from the W and SW with gusts of 40 mph.

Today will be mostly cloudy and temperatures will rise into the upper 30s F (40s F for the Bridger Range.  The mountains near Cooke City and West Yellowstone will get 6 inches of snow.  Mountains near Big Sky will get 2-3 inches and maybe only an inch near Bozeman.  Spring storms can be surprising, and I have little confidence in these snowfall amounts.  A lot more or a lot less could easily accumulate.

Overnight 1-2 inches of snow fell and temperatures dropped into the high teens to low 20’s F. This morning winds were blowing 5-10 mph from the SW with gusts of 20 mph. Today’s weather will bring a mix of clouds and sun with some precipitation this afternoon and tonight.   By afternoon winds will increase and blow 15-20 mph from the SW with gusts of 40 mph. Temperatures will climb into the high 30’s and low 40’s F. Another inch of snow should accumulate by tomorrow morning.

Yesterday was sunny with temperatures ranging from the high 20s near West Yellowstone to the low 40s in the Bridger Range.  Winds blew 15-30 mph out of the west, but calmed to 10-20 mph out of the southwest last night.  Clouds are streaming in from the southwest this morning and winds will increase slightly to 20-30 mph. Temperatures will be near 40F in the north and stay near freezing in the south.  In the mountains isolated showers will drop 1-2 inches of snow by tomorrow morning.

My, my, how fast things change.  The Bridger Range and mountains around Big Sky received 9-10 inches of snow last night, but not before a bit of rain fell at lower elevations.  The southern mountains received five inches and the northern Gallatins got an inch.  West winds are blowing 20-30 mph out of the west to southwest but will decrease to 10-20 mph today.  Mountain temperatures are currently reading in the upper teens to low 20s, twenty degrees colder than yesterday morning. Today will start cloudy, but turn sunny with mountain temperatures warming into the high 40’s in the north and high 30s in the south. No additional snow is predicted for the next 24 hours.
