Thanks to Sam Collentine for filling in for me on Tuesday! I had some injuries from nabbing a rock on Monday at the Bird (1st turn of the day) but somehow still managed to ride all day (Best day of the season for Utah). Typing was not possible yesterday.
Significant dry blower is falling per radar and the current models near the Montana Snowbowl near Missoula. Moderate snow is falling near Brundage in Idaho. The hot spots to watch will be the Tetons today (Storm Ski), most of north-central Montana resorts and perhaps southern Montana (Big Sky or Bridger).
As of 4:30 AM there were 3-5 inches at Brundage (Light to moderate additional), 4-6 inches at Grand Targhee, and 2-4 inches at JHMR. Snow was falling at all of these areas. Models show 5-10 inches by your last chair in the Tetons today (Very dry density feathers- very cold temps). You may actually be feeling bottom with the very low-density snow (20:1 snow ratio). If you're in southern MT aim for Big Sky with 4-8 inches expected by noon Wednesday (4-5 as of 4 AM). Bridger should see similar amounts.
As for the Wasatch some light snow today will turn moderate or heavy this evening. With high snow ratios, its likey you grab powder for Thursday morning (4-7 inches Park City- 6-10- Cottonwoods, 5-9 Northern Wasatch near Ogden.
Colorado grabs leftovers late Wednesday into Thursday morning. NW flow will bring 5-8 inches to most ski areas with Thursday morning being your best bet for a powder day. Steamboat may see higher amounts. Most snow will focus in the central and northern mountains from Aspen north including Summit, Eagle, and Grand County. Chase along I-70 based on snow reports Thursday morning but don't forget the Boat could sneak out higher amounts (Just a hunch). It's not a very moist system but with cold temps, just a small amount of moisture can bring some surprises. I might also favor the Gore Range near Vail due to the NW wind direction. Sunlight is also in the mix.
Enjoy the powder everyone! I might update this post tonight?
