Winter Storm Overview

As winter tightens its grip, snowfall warnings have been ramped up across Alberta, British Columbia, and Saskatchewan as residents prepare for an extensive and potentially dangerous snow event.

Forecast and Timing

Environment and Climate Change Canada has forecasted a significant snow accumulation, with predictions ranging from 15 to 25 centimeters over the coming days. The snowfall is expected to kick off in southern Alberta around midday Friday and could persist until late Saturday or early Sunday, intensifying on Saturday when the heaviest snow is forecasted.

Weather System Dynamics

What’s driving this weather phenomenon? A robust weather system is drawing moisture from the south Pacific, which will clash with a cold air mass from the north as it crosses the southern B.C. border. The interaction of these weather patterns is being compounded by the counterclockwise rotation within an inverted trough, complicating predictions about the exact snowfall totals in southern Alberta due to the imposing Rockies.

Areas of Concern

Although pinpointing the snowfall's maximum accumulation is challenging, meteorologists lean toward the southeast corner of Alberta receiving the highest totals. However, cities like Calgary might also find themselves on the cusp of significant snowfall as this storm system advances.

Temperature and Wind Chill Effects

The chilling reality for the region is that both daytime highs and overnight lows are forecasted to fall well below seasonal averages, lasting until at least the middle of next week. Wind chill factors could plunge temperatures to feel as frigid as -20°C, making for a bitterly cold weekend ahead.

Advisories and Preparations

Residents are advised to prepare for dangerous driving conditions and power outages that may arise from heavy, wet snow. With schools and workplaces possibly facing disruptions, communities are urged to stay informed and plan accordingly as this winter storm unfolds.
