Milder air is spreading into Montana this morning as chinook breezes develop along the Rocky Mountain Front.
Locations along the Hi-Line will remain in the colder air longer with highs struggling to climb above freezing this afternoon. Along I-15, temperatures will warm into the upper 40s and lower 50s.
Clouds will continue to increase through the day as our next storm system approaches from the west. Gusty winds will also develop with gusts up to 40 mph across the plains and over 70 mph possible in the higher passes. A High Wind Warning is in effect from noon today until 5am Saturday for the Rocky Mountain Front.
Snow will start to develop along the Divide overnight and then continue into Saturday. 2-7" of snow will fall at the higher elevations by Saturday morning and a Winter Weather Advisory has been issued for portions of the Rocky Mountain Front.
Rain showers will start to develop on the plains on Saturday as a cold front moves through. As colder air arrives Saturday night, much of the rain will change over to snow. Periods of light snow will then continue into Sunday night.
Forecast models this morning are indicating this will be a relatively weak storm system. Right now, I'm just expecting 1-3" of snow for the lower elevations. Mountain areas could see much more though with 6-9" of accumulation which could cause some tough travel across the higher passes.
Colder air will move in behind the front with highs in the 30s.
Warmer and drier weather returns next week as a ridge of high pressure builds across the West.
Have a great weekend!
