Mountain Weather

ISSUED: Friday January 30, 2015 10:00 MST

SYNOPSIS: A flattening upper ridge of high pressure will provide one more day of dry and partly cloudy conditions, fog patches are also expected this morning. Increasing cloud is anticipated early this evening and a few flurries are likely (70% chance) late overnight as a weakening upper trough pushes southeastward from the north-central coast. The upper trough in combination with the leading edge of an Arctic airmass clipping just west of Alberta supports further light snow and could also result in increasing winds Saturday morning. Partial clearing could follow during the late afternoon or more likely Saturday evening. A Pacific frontal system should track inland for increasing cloud later Saturday night-early Sunday and occasional (generally light) snow Sunday afternoon and Sunday night. The temperature could trend colder beginning tonight or early Saturday.

FREEZING LEVEL: A deep temperature inversion will persist today, a -2 to -6 degree layer should extend up to or slightly above 2000 metres. Otherwise rising to near 1200 metres this afternoon. Surface tonight and Saturday.

TODAY: Sunny with cloudy periods and patchy morning fog & low cloud. High near -2.

TONIGHT: Increasing cloud, 70% chance of flurries late overnight, accumulation from a trace to 3 cm. Windy at times. Low near -6.

SATURDAY: Mainly cloudy with a few flurries or occasional light snow during the morning, minor accumulation. Possible afternoon sunny periods. Windy at times. High near -4.

SATURDAY NIGHT: Fairly clear during the evening, increasing cloud overnight. Windy at times. Low near -10.

SUNDAY: Mainly cloudy, occasional light snow developing near or shortly before noon. Accumulation from 1 to 4 cm. High near -5. Occasional light snow Sunday night.

MONDAY: Mainly cloudy. Snow developing near noon, light accumulation. High near -3. Occasional snow and a few snow showers Monday night, moderate accumulation possible.

TUESDAY: Mainly cloudy with a few flurries during the morning, minor accumulation possible. Sunny periods developing during the afternoon. Windy at times. High near -5.

CONFIDENCE/DISCUSSION: Fair to good confidence today, fair beyond. A minor band of moisture embedded in the westerly flow aloft will provide cloudy periods this morning. The most recent guidance has increased the chance of light snow locally late overnight and Saturday morning but the amounts still appear minor. The Arctic airmass now appears to be mainly confined east of the Continental Divide on Saturday, it’ll still likely seep into the Fernie area for colder temperatures Saturday night. The computer models are relatively consistent with the timing and moisture content of the Sunday-Sunday night frontal system, low snow density could result in a greater than predicted accumulation during the afternoon and evening. A following system is currently suggested to produce more significant snow Monday afternoon and Monday night. An Arctic airmass could clip west of Alberta again Tuesday or Tuesday night.
