SYNOPSIS: A series of weak disturbances embedded in a northwesterly flow aloft will provide mainly cloudy skies and a few flurries or occasional light snow today and tonight. Similar conditions are expected Wednesday as the leading edge (warm front) of a Pacific frontal system drifts over an upper ridge of high pressure. The area of high pressure should be of greater influence for limited clearing and a reduced chance of flurries Wednesday night. The temperatures will gradually moderate.
FREEZING LEVEL: Surface.
FERNIE ALPINE RESORT FORECAST (1615 metres):
TODAY: Mainly cloudy with a few flurries or occasional light snow. Accumulation from 1 to 4 cm. Possibly windy at times, mainly at the upper elevations, high wind chill. High -12 or -13.
TONIGHT: Mainly cloudy with a few flurries or occasional light snow. Accumulation from 2 to 5 cm. Possibly windy at times, mainly at the upper elevations, high wind chill. Low near -14.
WEDNESDAY: Mainly cloudy with a few flurries or occasional (generally light) snow. Minor to light accumulation, possible 2 to 6 cm. High -8 or -9.
WEDNESDAY NIGHT: Cloudy with clear breaks and fog patches, slight chance of flurries. Low near -11.
THURSDAY: Cloudy with morning fog patches and possible afternoon sunny breaks or sunny periods. High near -4. Increasing or thickening cloud Thursday night. Low near -8.
FRIDAY and FRIDAY NIGHT: Mainly cloudy with a few flurries or occasional snow, light accumulation possible. Windy at times. High near -2. Low near -4.
SATURDAY: Cloudy with fog patches and a 40% chance of flurries during the morning, possible afternoon sunny breaks. High near -2.
CONFIDENCE/DISCUSSION: Fair confidence. This mornings guidance is in better agreement that there will be some snow at times during the next couple of days however the computer models are still highly variable when it comes to the local amounts of snow. The temperature profile is favourable for very low density snow which further complicates the snowfall predictions today, tonight and Wednesday. Greater than predicted amounts of powder are possible. A deep temperature inversion/stagnating airmass could result in an extensive coverage of low cloud & fog Wednesday night through Thursday night. A weakening Pacific system should push inland Friday and Friday night, its timing and moisture content are questionable. Another Pacific system could follow Saturday night-Sunday.
