SYNOPSIS: Fairly clear skies should persist this evening and dry, uneventful conditions are anticipated during the next several days as a strong, blocking area of high pressure remains over southern BC. This stable airmass should allow variable low cloud and fog patches to redevelop at times, mainly during the overnight and morning hours. A deep temperature inversion continues to develop, above freezing temperatures should develop at ridge top elevation.
FREEZING LEVEL: A freezing layer will redevelop at surface each night. Rising to between 1300 & 1500 metres Saturday & Sunday afternoons. A near to slightly above freezing layer is also expected at ridge top elevation.
FERNIE ALPINE RESORT FORECAST: TONIGHT: Mainly clear during the evening, variable low cloud and fog patches developing overnight. Low near -9.
SATURDAY: Variable low cloud and fog patches during the morning, dissipating to afternoon sunny periods. High near -3.
SATURDAY NIGHT: Mainly clear during the evening, low cloud and fog patches developing overnight. Low near -8.
OUTLOOK: SUNDAY: Cloudy with morning fog patches and afternoon sunny periods. High near -1.
MONDAY: Cloudy with morning fog patches and afternoon sunny periods. High near 0.
TUESDAY: Cloudy with sunny breaks. High near -2.
CONFIDENCE/DISCUSSION: Good on the general pattern, fair on the local sky conditions and temperatures. The February doldrums have set in, the main difficulty with this pattern is determining where the low cloud & fog will develop/dissipate. A light easterly flow may prevent or minimize the local development of the low cloud & fog tonight and Saturday morning, the resulting temperature would be cooler and then milder than the predicted values. With the stagnant airmass and temperature inversion expected to persist the low cloud could become more persistent Sunday & Monday. Low cloud can produce light flurries at times. Some guidance suggests a weak disturbance could clip the Rockies with a slight chance of flurries late Sunday night and Monday.
