ISSUED: Tuesday December 18, 2018 09:50 MST
SYNOPSIS: An intense Pacific wave in a mild westerly flow is bringing precipitation. Snow will change to flurries and snow showers this afternoon as the front passes just south of the area. Occasional snow showers or flurries will persist overnight but a minor ridge between disturbances should keep things mostly dry for Wednesday with temperatures a little cooler. Continued mild and unsettled in the outlook.
FREEZING LEVEL: Near 1200 metres this morning rising to near 1400 metres this afternoon. Falling to at or near valley bottom overnight and rising to 1200 metres tomorrow.
FERNIE ALPINE RESORT FORECAST (1615 metres):
TODAY: Periods of snow becoming flurries or snow showers this afternoon. Accumulation 6 – 12 cm. High near zero. Strong SW winds at elevation.

CONFIDENCE/DISCUSSION: Fair confidence, poor in the outlook. Mild and wet pattern continues. Most of the energy with the current intense wave is west of us, with precp being wrung out in the Selkirks and Purcells as well as south of the border. Tomorrow should be relatively uneventful between storms. Model solutions vary considerably for the Thursday event. Given a slightly different model scenario, a heavy precipitation event is possible with instability developing behind an earlier cold front passage on Thursday night, followed by a fairly quiet and slightly cooler period for a couple of days before the next storm rolls in later o the weekend.
