SYNOPSIS: A weak upper trough and its slight chance of flurries is currently exiting southeast of Fernie.  A dryer north-northwesterly flow aloft and surface based high pressure building from the central interior should result in a mixture of sun & cloud during the remainder of today and dry, partly cloudy conditions tonight through Wednesday night.  Relatively cold temperatures will continue.

FREEZING LEVEL: Surface.

FERNIE ALPINE RESORT FORECAST (1615 metres):

TODAY: Sunny with cloudy periods.  Slight chance of flurries, mainly during the early-mid morning.  Windy at times, high wind chill possible at the upper elevations.  High temperature -9 or -10.

TONIGHT: Clear with cloudy periods, greater cloud cover and fog patches possible overnight. Windy at times, mainly at the upper elevations.  Low near -16.

WEDNESDAY: Sunny with cloudy periods, patchy low cloud and fog possible during the morning.  High -8 or -9.

WEDNESDAY NIGHT: Clear with cloudy periods, increasing cloud and increased wind overnight.  Low near -14.

OUTLOOK:

THURSDAY: Cloudy with sunny breaks and a 40% chance of flurries.  Windy.  High -8 or -9.  60% chance of flurries or occasional light snow Thursday night, minor to low end light accumulation possible.  Low near -14.

FRIDAY: A mix of sun & cloud.  Slight chance of flurries, mainly during the early morning.  High near -8.  Low near -15.

SATURDAY: Possible morning low cloud and fog patches, otherwise mainly sunny.  High near -8.  Low -13 or -14.

CONFIDENCE/DISCUSSION: Fair to good confidence through Wednesday night, fair Thursday onward.  Limited moisture entrained in the northwesterly flow and airmass instability provide a slight chance of flurries this afternoon. A stagnating low level airmass could result in a patchy coverage of low cloud and fog tonight-Wednesday morning and again Wednesday night. The most recent computer models are trending lighter with the moisture content of the weak disturbances Thursday and Thursday night.  Thursday evening is currently favoured for a few flurries, any accumulation currently appears doubtful but more changes are possible.  High pressure should dominate again Friday afternoon through Saturday or Sunday, once again a stagnating low level airmass makes for some uncertainty of the local sky condition.
