|Alpine Weather Report|
ISSUED: Sunday February 16, 2020 10:15 MST
SYNOPSIS: A broad upper trough and its unstable airmass should provide variable cloud and a few flurries today. Variable cloud to partly cloudy skies are expected and limited flurries are also possible at times as patchy moisture/a series of very weak disturbances drift southeastward across the area tonight, Monday and Monday night. The temperatures should be near seasonal.
FREEZING LEVEL: Rising slightly above surface this afternoon and possibly again Monday afternoon.
FERNIE ALPINE RESORT FORECAST (1615 metres):
TODAY: Cloudy with a few flurries and possible sunny breaks. Accumulation from 1 to 4 cm. Gusty winds possible. High near -4.
TONIGHT: Cloudy with clear periods. 60% chance of flurries, early evening and again late overnight. Minor accumulation possible. Low near -12.
MONDAY: Cloudy with sunny periods and a 40% chance of flurries. High near -4.
MONDAY NIGHT: Cloudy with clear periods and a 40% chance of flurries. Low near -10.
TUESDAY: A mix of sun & cloud, possible morning low cloud and fog patches. High near -3.
WEDNESDAY: A mix of sun & cloud, morning fog and low cloud. High near -2.
THURSDAY: Cloudy with sunny periods, increasing wind during the afternoon. High near -1.
CONFIDENCE/DISCUSSION: Fair to good confidence except fair confidence of the local amount of snow today and this evening. Airmass instability is also a risk for local snow showers (greater rate of fall in comparison to flurries) this afternoon and early evening, a slightly greater than predicted accumulation of snow is possible. Most of the guidance suggests the cells will be confined south of Fernie. High pressure will gradually build inland from the coast Monday through Wednesday and is then suggested to flatten southward across southern BC on Thursday. A very weak disturbance entrained in the northwesterly flow aloft could maintain a slight chance of flurries Tuesday morning. A stagnating airmass and deepening temperature inversion support patchy to extensive low cloud Monday night through Thursday. A westerly flow could result in increasing or thickening cloud Thursday afternoon.
