While snow beings to melt here in Prince George hopefully this post will give some indication to the SPADE crew on the ground an idea of what to expect in the next 12-24 hours.
Summary: The low pressure system that brought snow to areas of British Columbia Friday night will impact the Eastern side of the Rockies this evening and into the morning of the 28th. The passage of a cold front expected to affect the study area Saturday evening will bring snowfall amounts in the region of 10-30 cm, with strong winds up to 90 km/hr occurring in the wake of the front, with peak wind gusts around Saturday midnight.
The cyclonic rotation of the storm as passes down the Eastern flank of the Rockies could bring higher snow amounts due to up slope flow that can already be observed on CMC radar.
Snow and winds will taper from the Northern areas first, following a southwards trend. The location of the low can be seen on the CMC surface analysis from 18z. The upper level low in the 500 hPa panel (12z) is still to the west of the surface low indicating the westwards tilt with height will support the further development of the storm until after it exits the study area.
Good luck folks!
