|Alpine Weather Report|
ISSUED: Saturday January 19, 2019 10:30 MST
SYNOPSIS: Snow should ease to scattered flurries as the current Pacific system exits east of the Rockies later this morning, near noon. Patchy moisture entrained in a strong and potentially unstable westerly flow should allow for mainly cloudy skies, scattered flurries or snow showers and gusty winds this afternoon and evening. Partial clearing is possible overnight. A system approaching the coast of Oregon should spiral moisture northeastward for mainly cloudy skies and a 60% chance of flurries Sunday and Sunday evening. A dryer northwesterly flow should develop for partial clearing later Sunday night. Today will be unseasonably mild, Sunday should be 2 or 3 degrees cooler.
FREEZING LEVEL: Rising to between 1100 & 1400 metres this afternoon. Surface tonight. Possibly rising slightly above surface Sunday afternoon.
FERNIE ALPINE RESORT FORECAST (1615 metres):
TODAY: Snow easing to a few flurries near noon. Mainly cloudy with a 60% chance of flurries during the afternoon. Accumulation from 4 to 8 cm. Windy at times, strong gusts possible. High near -1.
TONIGHT: Mainly cloudy with gusty winds, a 70% chance of flurries and possible snow showers during the evening. Accumulation from 1 to 4 cm. Cloudy with clear periods, fog patches and a slight chance of flurries overnight. Low near -5.
SUNDAY: Mainly cloudy with a 60% chance of flurries, minor accumulation possible. High near -3.
SUNDAY NIGHT: Mainly cloudy with a 60% chance of flurries during the evening. Cloudy with clear periods and possible fog patches overnight. Low near -8.
MONDAY: Sunny with cloudy periods, possible morning fog patches. High near -3.
TUESDAY: Mainly cloudy with a few flurries or occasional snow, minor or light accumulation. High near -5.
WEDNESDAY: A few flurries or occasional snow, light accumulation possible. High near -3.
CONFIDENCE/DISCUSSION: Fair confidence. Most of the guidance confines the main band of flurries north of Fernie this afternoon, local upslope conditions suggest otherwise. Airmass instability is a risk for local snow showers (greater rate of fall) this afternoon and more so early this evening. The main feed of moisture from Oregon-Washington should remain just south of the border but some guidance does now suggest a chance of light precipitation spreading just north of the 49th Sunday and Sunday evening, local upslope conditions are also favourable for a few flurries again. High pressure centred over the south coast should be the main feature of influence Monday. A series of weakening systems should push southeastward from the central coast Tuesday and Wednesday, the timing and moisture content of each will require some fine tuning.
