|Alpine Weather Report|
ISSUED: Thursday January 21, 2021 10:15 MST
SYNOPSIS: A minor feed of moisture from a small upper low pressure dropping southward off the coast of Washington-Oregon should result in a few bands of cloud today. A stagnating low level airmass should also allow for patchy low cloud and fog at times. Otherwise Fernie should generally reside between disturbances for dry and fairly clear to partly cloudy conditions during the next few days. The temperatures should continue to trend a few degrees colder.
FREEZING LEVEL: Surface.
FERNIE ALPINE RESORT FORECAST (1615 metres):
TODAY: Sunny with morning cloudy periods. High near -7.
TONIGHT: Clear with cloudy periods. Fog patches and more extensive low cloud possible overnight. Low near -13.
FRIDAY: Sunny with cloudy periods, greater cloud cover and fog patches possible during the morning. High near -7.
FRIDAY NIGHT: Clear with cloudy periods and possible fog patches. Low near -13.
SATURDAY: A mix of sun & cloud, possible morning fog patches. High near -8.
SUNDAY: Cloudy, possible early morning fog patches and sunny breaks. 50% chance of flurries by afternoon. High near -6. 60% chance of flurries Sunday night.
MONDAY: Cloudy with a few flurries or occasional snow, minor to light accumulation possible. Increasing wind possible during the afternoon. High near -8.
CONFIDENCE/DISCUSSION: Fair to good confidence through Saturday, fair beyond. Cloud associated with the coastal system could be confined south of Fernie by this afternoon. The patchy low cloud which developed in the vicinity of Fernie last night could briefly expand in coverage during the next couple of hours before it dissipates this afternoon. There’s greater uncertainty of the coverage and duration of the low cloud/fog patches late tonight through Saturday night or Sunday morning. Limited moisture could also clip just west of the Continental Divide for variable cloud or cloudy periods Friday night and early Saturday. A large upper trough is still anticipated to push southward from the north coast Saturday night and Sunday. A southwesterly flow should develop in its advance however the computer models continue to struggle with its moisture content and chance of light snow across southeastern BC Sunday and Sunday night. The upper trough is favoured to reside over western Washington-Oregon on Monday, some guidance suggests its main feed of moisture and light snow will remain just west of Fernie.
