SYNOPSIS: A large Pacific frontal system will gradually push eastward across southern BC for occasional snow, a few flurries (rising snow level) and increased wind at times today, tonight and Friday morning. An upper trough should follow the cold front for a few snow showers and then scattered flurries Friday afternoon and evening. Lingering moisture suggests variable cloud and limited flurries later Friday night. The temperatures should trend a few degrees milder.
FREEZING LEVEL: Rising to between 1400 & 1600 metres this afternoon and tonight, a near freezing layer could also develop above 2000 metres. Similar Friday morning, trending lower Friday afternoon.
FERNIE ALPINE RESORT FORECAST (1615 metres):
TODAY: Cloudy with occasional snow, accumulation from 6 to 12 cm. Windy at times. Small risk of freezing rain. High near -1.
TONIGHT: Cloudy with a few flurries, occasional snow developing late overnight. Accumulation from 3 to 8 cm. Small risk of freezing rain. Windy at times. Low near -2, possibly trending slightly milder overnight.
FRIDAY: Periods of snow during the morning, a few afternoon snow showers or flurries. Light to moderate accumulation, possible 8 to 15 cm. High near 0, possibly trending cooler during the afternoon.
FRIDAY NIGHT: Mainly cloudy. A few evening flurries, 60% chance of flurries overnight. Minor to light accumulation possible. Low near -3.
SATURDAY: Cloudy with possible sunny breaks and morning fog patches. 40% chance of flurries, early morning and again late in the day. High near -1.
SUNDAY: Periods of snow, rising snow level. Light to moderate accumulation. Windy at times. High near 0.
MONDAY: Mainly cloudy with a 60% chance of flurries. High near -2.
CONFIDENCE/DISCUSSION: Fair to good confidence of the general pattern, all of the guidance is in agreement to maintain an active and relatively mild pattern during the next several days. Fair confidence of the local details, the timing and moisture content of each system are questionable, changes are likely. The current wave of moisture (warm front) is favoured for relatively steady snow today, light accumulation. The snow is expected to ease between fronts this evening and then redevelop late overnight or early Friday morning as the cold front approaches. The cold fronts passage and airmass instability in its wake could result in highly variable snow showers Friday late morning and early-mid afternoon. The next disturbance appears likely to largely dissipate before reaching the Rockies but could produce a few flurries Saturday night. A more significant wave of Pacific moisture is expected Sunday. An upper trough should follow Sunday night. There’s also some uncertainty of the snow level this afternoon through Friday and again Sunday, it could rise to near 1500-1600 metres at times.
