Strong SW winds will continue today. By tomorrow morning the southern half of the advisory area should get 2-3 inches of snow with more falling during the day on Saturday.
Last night most places received a trace to 2 inches of snow while the mountains near Cooke City received 3-4 inches. Temperatures did not cool overnight and were near freezing in the Bridger Range and mid 20’s F all other places. The big story is winds which were dead calm yesterday morning, but increased significantly this morning averaging 10-20 mph from the SW and gusting 30-50 mph. Snowfall will return late Friday night though we may see a few snowflakes fall between now and then. Strong southerly winds will continue and push temperatures near 30 degrees F or higher today.
Snowfall yesterday and last night favored the Yellowstone Club with a foot of powder. The northern Madison, Gallatin and Bridger Ranges show 6-8 inches, while only 2-4 inches fell in the south. Winds decreased yesterday afternoon and are currently 5-10 mph out of the west to north. Mountain temperatures are in the mid-teens under mostly cloudy skies. Today will see some sun but cloud up again tonight with a trace to an inch falling by morning.
Cooke City received another six inches of snow, most of it falling last night, while the other mountain ranges just received wind. Under mostly cloudy skies mountain temperatures are in the low to mid 20s with west to southwest winds gusting 35-50 mph and averaging 20-30 mph at the ridgetops. Today will be windy and cloudy with snow falling later this afternoon. By morning the northern mountains could have 3-4 inches, the mountains towards West Yellowstone 4-6 inches, and Cooke City 6-10 inches. Winter is back!
