|Alpine Weather Report|
ISSUED: Saturday March 21, 2020 10:15 MDT
SYNOPSIS: A weakening upper trough will clip southeastward along the Rockies with variable cloud, increased wind and a 30-60% chance of flurries this afternoon and evening, the greater chance of flurries during the evening. High pressure should briefly rebuild in its wake for partial clearing overnight and dry, fairly sunny conditions during the majority of Sunday. Increasing cloud is expected Sunday afternoon or evening as an upper low pressure tracking southward along the coast begins to spread patchy moisture inland.
FREEZING LEVEL: Rising to near 1700-1800 metres early this afternoon. Surface tonight. Rising to between 1400 & 1600 metres Sunday afternoon.
FERNIE ALPINE RESORT FORECAST (1615 metres):
TODAY: Mainly sunny during the morning. Increasing cloud and gusty winds during the afternoon, 30% chance of late day flurries. High near 2.
TONIGHT: Mainly cloudy with gusty winds a 60% chance of flurries during the evening, minor accumulation possible. Clear with cloudy periods overnight. Low near -7.
SUNDAY: Sunny with cloudy periods, increasing cloud mid or late afternoon. High near 1.
SUNDAY NIGHT: Cloudy with clear breaks. Windy at times. Low near -4.
MONDAY: Cloudy with sunny breaks. 40% chance of flurries, mainly during the afternoon. High near 1. 70% chance of flurries or occasional snow late Monday night, minor to light accumulation possible.
TUESDAY and TUESDAY NIGHT: Cloudy with a few flurries or occasional snow and possible snow showers. Light to moderate accumulation possible. Windy at times. High near -2. Low near -8.
WEDNESDAY: Mainly cloudy with a 70% chance of flurries during the morning, minor accumulation possible. Cloudy with sunny breaks and a slight chance of flurries during the afternoon. High near -2.
CONFIDENCE/DISCUSSION: Fair to good confidence today and again Sunday, otherwise fair confidence. The main band of flurries appears likely to skirt just east of Fernie this evening, its passage also appears brief. The upper low pressure is favoured to gradually continue southward along the coast or stall over the coast of Washington-Oregon Monday and Tuesday. The majority of the precipitation associated with the developing southwesterly flow is still suggested to remain west of Fernie Monday and the majority of Monday night. A large upper trough (associated with the upper low) and its unstable airmass increases the likelihood of a few flurries and variable snow showers of hit & miss coverage Tuesday and Tuesday night. A cooler airmass could also seep just west of Alberta Tuesday afternoon and Tuesday night. Limited moisture should linger early Wednesday, a drier northwesterly flow could develop Wednesday afternoon.
