Short Term Forecast
Below: The iconic Mt. Assiniboine under the frigid stillness of -28C Sunday morning at Sunshine Village.
Sunday: An arctic high-pressure ridge expands across the Rockies delivering clear skies north to south. It will be a sunny and frigid day for all resorts with alpine high temps rising to a humane -16C to -20C by midafternoon. Light W/SW winds. Frostbite concerns, cover all exposed skin.
Monday: Arctic high-pressure hangs in for most of the day on Monday before a weak disturbance brings increasing cloud cover moving north to south along the Rockies during the afternoon hours, with isolated flurries developing from Sunshine north to Marmot Basin. Moderate and gusty W/NW winds to 25 kph on Monday. Temps begin to moderate with alpine (2200m) high temps of -13C to -15C on Monday.
Tuesday: Widespread isolated flurries continue overnight Monday and into Tuesday morning with accumulations of a trace up to 8cm by noon Tuesday are 30% possible, mainly from Sunshine north to Marmot Basin. For Norquay, and the resorts south of Banff, skies generally will be a mix of sun and clouds. Moderate west winds for most resorts with gusty NW winds likely across the alpine at Castle Mountain. Upper-mountain high temps (2200m) across the Rockies warming to -10C to -14C on Tuesday.
Wednesday: Lingering cloud cover and chances of isolated flurries continue across the northern half of the Alberta Rockies (Banff to Jasper) as a trough of low-pressure persists. Trace accumulations up to 5cm possible by last chair Wednesday at Sunshine, Louise, and Marmot. South of Banff, mainly cloudy with some sunny spells. Predominantly west winds light increasing to moderate in the afternoon. Warming trend continues with highs at 2200m of -8C to -11C.
Thursday: Transient high-pressure builds across the Rockies on Thursday bringing a mix of sun and cloud to most resort locations. SW winds light to moderate will keep the warming trend going with alpine highs at 2200m ranging from -2C at Castle, to -7C at Louise.
Below: Canadian model for snowfall across BC and AB from 11am Monday 1/30 thru 11am Thursday shows decent chances of daily accumulations for the mountain from Banff north to Jasper.
All three models are pointing towards a Pacific trough moving into the Rockies beginning Friday 2/3 bringing chances of daily accumulating snow through the weekend as two shortwave lows move through on an active NW flow aloft. Temps will become slightly cooler but stay right around seasonal in temps through the weekend. Still too early to nail down numbers on daily snowfall amounts but most of the models are bringing these systems across the Alberta Rockies from Banff north to Jasper. Stay tuned.
Below: The Euro model for the period Thursday afternoon through Monday morning shows potential for a snowy Friday 2/3 through Sunday 2/5.
As always, thanks so much for tuning in. Next update, Tuesday 1/31.
